Description
The application is a divisional application of a patent of a slope plant-growing base material fixing method capable of effectively preventing collapse and landslide, with an application number of 202010899143.6, an application date of 2020-08-31.
Technical Field
The invention relates to the technical field of ecological restoration greening, in particular to a top anchoring type slope vegetation base material greening system.
Background
Due to mineral resource mining and road engineering construction in arid and semiarid regions, the landform and the ecological environment of a large number of closed-pit mines and roads along the line are seriously damaged, and a plurality of rocky slopes with large gradients and high heights appear. Generally, the steep rocky slope is not covered by planting soil, has small rain bearing area and poor water retention, and is difficult to repair vegetation on the slope due to little rainfall in a drought region and unstable rock mass on the slope. And the ecological environment is seriously influenced because the ecological environment can not be restored, so geological disasters such as collapse, falling rocks and the like are caused. Therefore, the vegetation restoration of the artificial high and steep rocky slopes along the closed-pit mines and roads in the dry area is urgently needed.
At present, for low (slow) rocky slopes in humid and semi-humid areas, vegetation restoration is mainly carried out by two technologies of piling vegetation soil bags on the slopes and spraying vegetation soil (common vegetation concrete) on three-dimensional nets. However, the vegetation restoration technology for the high and steep rocky slope in the arid region is still not mature, and the two conventional restoration technologies for the vegetation restoration of the high and steep rocky slope in the arid region have the following problems: and (1) the construction is difficult and the cost is high. The three-dimensional net spray seeding technology has large and dangerous working load and high construction cost on the anchor rod operation of the high and steep rocky slope; the method for piling the plant-growing bags has the advantages of high risk, large workload, large thickness of the plant-growing bags and high cost when the plant-growing bags are piled on the high and steep rocky slope surface with unstable rock mass. (2) applicability is limited by complex terrain environments. The three-dimensional net spray-seeding technology is characterized in that the spray-seeding equipment is limited by terrain and roads in transportation, and spray-seeding water in partial areas is difficult to obtain; the stacking height of the stacking vegetation bags on the high and steep rocky slope is limited, and the vegetation soil on the high and steep rocky slope is easy to collapse or slide along the shallow layer of the slope and other geological disasters. (3) Has no supporting function on the rock blocks of the high and steep rocky slope. (4) Rainwater can not be collected and stored, irrigation water can not be automatically regulated and controlled, the water retention of a single vegetation soil layer is poor, so that long-term sufficient moisture can not be provided for the slope vegetation of the high and steep rocky rocks in the arid region, the vegetation restoration time is long, the effect is poor, and the later cultivation cost is very high.
CN201910384331.2 discloses a method for greening and repairing a hard slope, which comprises slope cleaning, anchor rod setting, galvanized wire mesh sheet laying, red sandstone improvement planting soil, geomembrane laying, seeding, automatic irrigation system establishment, operation and maintenance, improvement by doping modifying agents into red sandstone rock-soil layers with different sandstone contents, and meanwhile, a spray head is installed on a pre-buried spraying system by utilizing an automatic control system, plants are irrigated through the spray head, and the spray irrigation system can be automatically controlled according to temperature and humidity. The invention discloses a means of anchoring by adopting an anchor rod and carrying out sprinkling irrigation by adopting rainwater collection. The following drawbacks still remain: 1 simple anchoring can not provide a supporting effect with enough strength, and deep anchoring has the defects of difficult operation, high anchoring risk, reduced slope stability and the like. 2, rainwater is directly collected for sprinkling irrigation, dirt is easily mixed in the rainwater to cause pipeline blockage, and the sprinkling irrigation electric control equipment in the field environment is restricted by power supply conditions and is easy to lose efficacy; 3 the water-holding capacity of the plant growth structure is limited, the plant growth structure needs to depend on more frequent sprinkling irrigation times, the cost is higher, and the plant growth structure is not beneficial to long-term maintenance.
Therefore, how to provide a technology suitable for ecological restoration of a high and steep rocky slope in a dry area can improve the supporting and fixing effects on the rock blocks of the high and steep rocky slope; can collect rainwater regularly and water better, reduce the irrigation control and to the dependence of consumer, improve afforestation effect, ecological remediation effect, improve construction safety and economic nature, become the domatic vegetation restoration technical research of high steep rock in arid area and await the critical problem of solving urgently.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a method for fixing a slope plant-growing base material, which can improve the fixing and supporting effect on the slope plant-growing base material, reduce the construction difficulty and effectively prevent a collapse and a landslide, and is particularly suitable for vegetation restoration of a high and steep rocky slope in a arid region, wherein the high and steep rocky slope is a rocky slope with the height of more than 20 meters and the slope within the range of 50-90 degrees. Still provide a corresponding top anchor formula side slope plant and grow substrate greening system.
In order to solve the technical problems, the invention adopts the following technical scheme:
a side slope plant-growing base material fixing method capable of effectively preventing landslide and collapse is characterized in that anchor piles are arranged at the top of a side slope to provide tensile force as supports, and the plant-growing base material is supported by adopting anchor cables which are vertically arranged and the upper ends of the anchor piles are connected to the anchor piles and a rib belt net which is transversely arranged layer by layer and connected to the anchor cables, so that the plant-growing base material is prevented from collapsing and landslide.
By adopting the method, the anchor rod does not need to be arranged on the slope surface of the side slope for fixing, the construction difficulty and risk can be greatly reduced, and the construction safety is improved. Meanwhile, the top anchor pile is used as a stress support mode, so that the construction of the anchor pile is facilitated, the top anchor pile can better bear downward tension, and the fixing and supporting effect on the vegetation base material is improved.
The method is realized by adopting the following top anchoring type slope plant-growing substrate greening system which comprises a rainwater collecting and storing unit arranged at the top of a slope, plant-growing substrates laid and fixed on the slope, an anchoring system used for fixing the plant-growing substrates and an irrigation pipe network embedded in the plant-growing substrates, wherein the water inlet end of the irrigation pipe network is connected with the rainwater collecting and storing unit; the anchoring system comprises a plurality of rib belt nets transversely arranged along the side slope, spaces for stacking plant growth substrates are formed above the rib belt nets, two sides of the rib belt nets are fixed on anchor cables vertically arranged along the side slope, and the upper ends of the anchor cables are fixed on anchor piles at the top of the side slope.
Thus, the transversely arranged reinforcing mesh bears the gravity of the plant-growing base material on the side slope, and the gravity is transferred to the anchor piles at the top of the side slope through the anchor cables. Therefore, the anchor pile is constructed at the top of the side slope more conveniently, simply and safely, the anchor pile can be constructed more deeply to bear larger tensile force, and meanwhile, compared with the mode that a vertical anchor pile is arranged on the side slope, the anchor pile at the top is vertically arranged to bear oblique downward tensile force, so that the anchor pile is more difficult to be cast off, and the anchor rope can generate pressure towards the inside of the side slope to maintain the stability of the slope rock mass; the slope surface of the side slope is not required to be deeply drilled with anchor holes, so that the self structural stability of the side slope is maintained. Therefore, the plant growth base material on the side slope can be fixed more conveniently, quickly, efficiently and reliably, and the reliability of ecological restoration is improved.
Further, the anchor cables are arranged in groups, each group is provided with two anchor cables, the two anchor cables are arranged at intervals along the plane perpendicular to the side slope, a plurality of rib belt nets are arranged between every two adjacent groups of anchor cables at intervals along the height direction of the side slope, and the inner ends and the outer ends of the two sides of each rib belt net are respectively fixed on the two anchor cables of each group.
Therefore, each group of two anchor cables can facilitate the installation and the bearing of the rib belt net, and the anchor cables and the rib belt net divide the slope into a plurality of corresponding grid spaces, so that an effective three-dimensional flexible force transmission structure is formed on the slope surface; the plant growth materials stacked in each space bear the gravity by the rib belt net and act on the double-layer anchor cables on two sides, and then are transmitted to anchor piles on the top of the slope through the double-layer anchor cables, so that the pressure of the plant growth base material of the upper grid space unit on the plant growth base material of the lower grid space unit is very small and cannot be influenced by the slope height, and the height of the slope plant growth base material is not limited by the slope height; can better realize the fixation of the plant growth material.
The anchor cable is preferably made of high-strength steel cable to better guarantee the strength.
Furthermore, the rib belt net is composed of rib belts and positioning steel bars at two ends, the rib belts and the positioning steel bars are horizontally arranged on the slope, and the positioning steel bars at the two ends of the rib belt net are connected with the double-layer anchor cables at two sides through anchor cable buckles.
Like this, can make things convenient for the erection joint of muscle area net fixed, and can guarantee the fixed reliability between muscle area net and the anchor rope better, avoid the muscle area to break away from the anchor rope under the action of plant living material gravity.
Preferably, the length of the rib belt net is about 2m, the width of the rib belt net is about 23cm, and the vertical interval of the rib belt net on the slope surface is about 1.5 m. Therefore, the plant growing material in the grid unit where each rib belt net is located has moderate gravity, and the stability and the reliability of integral fixation are ensured.
Furthermore, in each group of anchor cables, the anchor cable close to the inner part is away from the bottom of the slope surface by a certain distance.
So because plant and grow in the substrate innermost layer be the soil dressing layer, so this structure can be when guaranteeing the fixed effect of muscle area net to the maintenance of vegetation substrate, leave a section spacing distance between muscle area net and domatic bottom for domatic bottom is piled up and is planted the soil dressing layer that is located the bottom in the living substrate and can be linked into one piece, makes things convenient for vegetation's root system to get into can tightly grasp side slope rock surface better after the soil dressing layer and extend the growth one-tenth. And then can rely on plant roots to better improve the stability of whole slope greening system structure after the plant grows out. This distance is preferably 2cm, which makes it possible to optimize the effect described above.
Further, the anchor pile is a profile steel concrete pile, a pile body of the anchor pile is embedded and fixed in a slope top rock stratum, a pile top and a middle-lower part (preferably a part which is about 20cm away from the ground) of the anchor pile are respectively provided with an anchor cable hole which is through from front to back and is inclined, and an anchor is installed in the anchor cable hole and used for fixing the anchor cable.
Therefore, the self structural strength of the anchor pile can be better ensured, the bearing effect on the anchor cable is ensured, and the gravity load of the slope plant-growing base material transmitted by the anchor cable is borne.
Furthermore, the edge position of the top of the side slope corresponding to each group of anchor cables is also provided with a guide pier, a guide limiting hole penetrates through the guide pier along the front-back direction, and the upper end of each anchor cable penetrates through the guide limiting hole and then is fixed on the anchor pile backwards.
Therefore, the anchor cables are guided by the guide piers to change the direction and then are connected with the anchor piles, the guide piers can arrange all groups of anchor cables at different positions of the slope top according to design, force bearing and force transmission are better realized, partial anchor cable tension can be decomposed and offset, and the stability and reliability of the whole anchoring system are better improved. When the anchor cable guide device is implemented, the guide piers are arranged at intervals of about 2m and are consistent with the intervals of two adjacent anchor cables.
Furthermore, the guide pier is a reinforced concrete pier and is embedded in the slope top bedrock, steel pipes are embedded in the top and the middle lower portion of the guide pier respectively along the front and back direction, and guide limiting holes of the guide pier are formed in inner holes of the steel pipes.
Thus, the construction and arrangement of the guide pier are facilitated. During implementation, a steel pipe with the inner diameter about 1.1 times of the diameter of the designed anchor cable is preferably adopted, so that the anchor cable can conveniently pass through the steel pipe.
Furthermore, still be provided with a locating lever on the domatic at vertical interval that every anchor rope of group corresponds the place, the locating lever lower extreme is fixed to domatic, and locating lever top and middle part are provided with the locating hole along the anchor rope direction is run through, and anchor rope slidable ground passes the locating hole.
Like this, because the pulling force of anchor rope is born by the anchor stake, the locating lever does not bear plant living substrate gravity basically, and the locating lever effect is mainly kept the anchor rope and arranges according to required position and interval. Therefore, the lower end of the positioning rod only needs to be fixed to the slope surface shallowly, and the slope surface structure is not damaged by drilling deep anchoring holes on the slope surface. Therefore, the construction is convenient, and the overall stability of the system can be better improved.
During implementation, the better size parameter selection is that the distance between every two positioning rods is about 2-3m, the length of each positioning rod outside the slope rock wall is about 30cm, the positioning holes in the middle lower parts of the positioning rods are arranged about 2cm away from the slope, and the inner diameter of each positioning hole is about 1.1 times of the diameter of the designed anchor cable. The positioning effect can be optimized.
And further, an anchor rod is arranged at the bottom of the side slope below each group of anchor cables, the lower end of the anchor rod is anchored in a rock stratum at the bottom of the side slope obliquely downwards, the bottom of each anchor cable is fixedly connected to the anchor rod through an anchor cable buckle, and the anchor cables are in a prestress state applying pressure to the positioning rod to the slope body.
Like this, the setting of stock for both ends are by the tensioning about the anchor rope and are the prestressing force state of inside applied pressure, make the locating lever inwards compress tightly like this, are difficult for droing more, can improve whole anchoring system's stability and reliability better.
Thus, after the anchoring system is arranged, each group of vertical anchor cables and horizontal rib belt nets form an effective three-dimensional flexible force transmission structure on the high and steep rocky slope, when the plant-growing base material is laid on the high and steep rocky slope, the gravity of the plant-growing base material is transmitted to the vertical double-layer anchor cables through the rib belt nets and then transmitted to anchor piles on the top of the slope through the double-layer anchor cables, and therefore the top-anchored plant-growing base material fixing system (namely the anchoring system) is formed. Because the top anchor type plant growth substrate fixing system divides the slope plant growth substrate into a plurality of units of 2m multiplied by 1.5m, the units are mutually independent, and the gravity of each unit is transferred to the anchor pile at the top of the slope by the pulling force of the anchor rope to balance, so that the pressure of the plant growth substrate of the upper unit on the plant growth substrate of the lower unit is very small and cannot be influenced by the slope height, the height of the slope plant growth substrate is not limited by the height of the slope, and the thickness of the plant growth substrate can be kept unchanged along the whole slope height; meanwhile, the damage of a single unit only has little influence on the adjacent lower unit, so that the integral collapse disaster of the vegetation base material cannot happen; in addition, compared with a slope stressed anchor rod of a three-dimensional plant spraying technology, the top anchoring type plant growth base material fixing system is not acted by the downward gravity of the plant growth base material on the locating rod of the slope, so that the distance between the fixing points is large, the requirement on the embedding depth is low, the high-risk workload of a high and steep rocky slope can be greatly reduced, and the construction difficulty and the safety are effectively improved; furthermore, double-deck anchor rope can exert a perpendicular domatic power inwards through the locating lever to not only can not cause adverse effect to the domatic stability of rock matter, the domatic stability of improvement can be imitated to the contrary.
Preferably, the irrigation pipe network comprises a dry flow pipe arranged downwards along the slope surface of the side slope, a water inlet at the upper end of the dry flow pipe is connected with the automatic irrigation device (specifically connected with the bottom of the water control chamber), branch pipes are arranged on the dry flow pipe in a communication mode at intervals, the branch pipes are horizontally arranged along the side slope and buried in the plant growth substrate, and seepage holes are arranged on the branch pipes at intervals.
Like this, automatic watering device is in time quantitative during the watering and is supplied the watering water to the mainstream intraductal, through each tributary pipe and the infiltration hole on it, directly the infiltration enters into in the plant living substrate, can avoid the evaporation of water better, has improved the utilization effect to the water resource.
Furthermore, a plurality of shutoff type water outlets are arranged in the main flow pipe at intervals from top to bottom; the intercepting type water outlet comprises a water outlet joint communicated with the main flow pipe, the lower side edge of the joint of the water outlet joint and the main flow pipe extends obliquely upwards to the inner cavity of the main flow pipe to form a sheet-shaped water receiving bulge, and the edge of the water receiving bulge and the inner cavity of the main flow pipe are encircled to form an intercepting groove; the outer end of the water outlet joint is fixedly connected with the branch pipe.
Therefore, in the application, the irrigation is performed at regular time and quantity in each time, and the problems that the irrigation close to a water source is sufficient and the irrigation at the tail end of a pipe network is insufficient due to long-time small-flow irrigation are solved. The regular and quantitative irrigation has the characteristics of large water volume and short time, and if the conventional irrigation pipe network is arranged, the equivalent irrigation of branch pipes with different heights on the same main flow pipe cannot be realized. Therefore, the interception type water outlet structure is arranged in the application. When the main flow pipe supplies water quantitatively each time, the water supplied quantitatively flows downwards from the main flow pipe, and each branch flow pipe is intercepted actively by the intercepting groove to smoothly and rapidly introduce the water into each branch flow pipe, so that the water supply effect of each branch flow pipe is ensured. Meanwhile, the structure can ensure the balance of water amount accessed by the branch flow pipes at different heights by adjusting the size of the intercepting groove, thereby providing a balanced irrigation effect.
As optimization, the upward inclination angle of the water receiving bulge is about 45 degrees.
Therefore, the water retaining device can ensure a better water retaining effect and has better structural strength to avoid being quickly damaged by water flow scouring.
Preferably, the intercepting type water outlets are arranged on the main flow pipe at intervals from top to bottom and from left to right.
Therefore, the uniformity of the water quantity intercepted by each branch pipe is improved.
Preferably, the end part of the water inlet end of the branch pipe is bent or inclined upwards and then is connected to the water outlet joint.
Therefore, the intercepted irrigation water is more conveniently led into the branch flow pipes by the intercepting type water outlets.
Further, the height of the upward bending or the inclination of the end part of the water inlet end of the branch pipe is 50cm. Irrigation water can be better introduced into the branch pipes.
As a structure mode, the intercepting area of the intercepting groove of each intercepting type water outlet is gradually increased from top to bottom along the main flow pipe.
In this way, the simultaneous water interception of the branch pipes can be better realized under the condition of timing and quantitative irrigation. The water inflow time of the main flow pipe is the same, so that the water amount intercepted by each branch flow pipe is approximately equal. And the irrigation water in each branch flow pipe flows in at the same time, so that the irrigation uniformity of the whole irrigation pipe network can be better improved.
As another structure mode, the edge of the water receiving bulge in each intercepting type water outlet is in a semi-elliptical shape as a whole, and the diameter of the short side is the same as the inner diameter of the main flow pipe, so that the intercepting groove occupies half the cross-sectional area of the main flow pipe.
By adopting the structure mode, a pair of branch flow pipes which are opposite to each other at the left and right sides in the middle upper part of the main flow pipe can intercept pouring water and fill the pouring water, and then overflow from the interception type water outlet to flow downwards. So that the branch pipes with different heights are filled with water one by one from top to bottom. This has the advantage of facilitating more accurate calculation and control of the amount of water required for each pour. The defects are that the upper main flow pipe is filled with water firstly, the irrigation is often longer, the irrigation uniformity is influenced, and the irrigation uniformity can be improved by adjusting the way that the distance between the adjacent main flow pipes is gradually reduced from top to bottom.
Furthermore, the diameter of the main flow pipe is about 10cm, and the diameters of the water outlet joint and the branch flow pipe are about 5 cm. Better guarantee the drainage watering effect.
As optimization, a water guide layer with strong capillary action is arranged in the plant growth base material, and the branch pipe is buried at the position of the water guide layer.
Thus, the irrigation water which is easy to permeate from the water seepage holes of the branch flow pipes can slowly permeate to the whole side slope through the water guide layer to realize irrigation.
Preferably, the water guide layer is made of a geotechnical blanket, and the branch pipes are wrapped in the geotechnical blanket.
The fine effect of geotechnological blanket is excellent like this, can realize evenly distributed water better, and the branching pipe parcel can play good protection effect in it simultaneously, avoids in the soil entering such as worm or silt and destroys the branching pipe.
Furthermore, an exhaust pipe which extends upwards to form the plant growing base material and is communicated with the atmosphere is arranged at the tail end of the branch pipe.
Can make things convenient for the lateral flow pipe entry end to introduce the watering water of holding back more smoothly like this through the quick exhaust of blast pipe to make the watering water of entering lateral flow pipe fill whole pipeline rapidly, then rely on the infiltration hole to slowly ooze water realization watering again. The defects that the watering effect is good when one end of the main flow pipe is close to and the watering effect is poor when one end of the main flow pipe is far away from are overcome. The uniformity of irrigation is better ensured.
Further, the upper end of the exhaust pipe is bent downwards.
The blockage caused by the fact that mud or sundries enter the exhaust pipe can be better avoided.
Further, the upper end of the exhaust pipe is higher than the corresponding intercepting type water outlet of the branch pipe during implementation. The waste of irrigation water flushed from the exhaust pipe can be better avoided; the height of the exhaust pipe can be about 1 m during implementation. During implementation, the diameter of the exhaust pipe can be 1cm, the exhaust requirement can be met, and impurities can be better prevented from entering the exhaust pipe.
In the implementation process, a better choice is that a water seepage hole is arranged on the pipe wall of the lower edge of the branch pipe at intervals of about 15cm, so that the slope in the whole range of the branch pipe can be uniformly irrigated.
As optimization, the automatic irrigation device also comprises an automatic irrigation control device arranged between the water storage chamber of the rainwater collection and storage unit and the irrigation pipe network, and the automatic irrigation control device is used for controlling the water storage chamber to supply water to the irrigation pipe network at regular time and quantity.
Therefore, the timed and quantitative water supply control of the processing pipe network can be realized, and the timed and quantitative irrigation effect is ensured.
Further, automatic watering controlling means, including being located a accuse hydroecium of aqua storage room below, the accuse hydroecium support that has vertical setting in the accuse hydroecium, accuse hydroecium support upper end is articulated to be provided with accuse water tank, accuse water tank bottom proportion is greater than rest part proportion and pin joint is located the middle part and leans on the rear position, make when accuse water tank is empty the focus be located pin joint rear position and contain water to certain proportion after the focus can be forward (indicate towards accuse water tank export end direction) exceed the pin joint position, the case mouth is upwards and just to setting up with the aqua storage room delivery port when accuse water tank is empty, the case mouth is just right with the dry flow pipe entry of watering pipe network when accuse water tank mouth tumbles downwards.
Therefore, the reversible water control tank is arranged in the water control chamber, the center of gravity of the water control tank enables the tank opening to be upward when the water control tank is empty, the water stored in the upper water storage chamber is injected into the water control tank through the water outlet, and after the water injection exceeds a certain proportion, the tank opening of the water control tank is tilted downward and water is poured into the inlet of the main flow pipe of the irrigation pipe network. Thus, the pure mechanical structure is adopted to realize the quantitative control of rainwater entering the irrigation pipe network each time. An electric control valve is not needed, the restriction of power utilization is avoided, the reliability and the stability are better, and the service life is longer.
Furthermore, the plane where the tank opening of the water control tank is located is obliquely arranged, and the plane where the tank opening is located is upward in an empty tank state.
Like this, the hydroenergy of storage water tank can flow into in the accuse water tank better when making things convenient for the empty case state, and hydroenergy can pour the main current pipe inlet of watering pipe network in better when the accuse water tank is emptyd.
Furtherly, the accuse water tank includes outside alignment jig and installs the box in the alignment jig, and the alignment jig is whole to be the trough-shaped and articulates in accuse water tank support upper end, and alignment jig both sides level runs through and is provided with regulation set screw, adjusts set screw rotationally connect on the alignment jig and inner and box butt realize the fixed of box, and the position grafting of alignment jig groove bottom is provided with the balancing weight.
Like this, can be through changing the upper and lower position of box in the alignment jig to the cooperation increases and decreases the balancing weight, adjust the flourishing water yield size of water control box when tumbling in a flexible way, make the water yield of pouring into in the watering pipe network at every turn can adjust to and slope area size better match the correspondence.
Furthermore, a water pipe is arranged in the water storage chamber, and the lower end of the water pipe penetrates out of the water storage chamber downwards in a sealed mode and extends to the position above the opening of the water control tank.
Therefore, rainwater in the water storage chamber can be accurately introduced into the water control tank by virtue of the water through pipe.
Furthermore, the water pipe is a hose, the length of the water pipe exceeds the height of the inner cavity of the water storage chamber, the upper end of the water pipe is connected with a flow control floating ball floating on the water surface, the part of the flow control floating ball immersed under the water surface is transversely provided with a flow limiting hole in a penetrating manner, the flow control floating ball is also vertically provided with an air hole in a penetrating manner, and the air hole is communicated with the flow limiting hole in a crossing manner; the lower end of the vent hole is communicated with the upper end of the water pipe in a sealing way.
Like this, the water in the water storage chamber can flow through the interior outflow of restriction orifice drainage water pipe to the accuse water tank in, and the restriction orifice can set up sufficient little so that the extension is held water in the accuse water tank and is toppled over once required time. The flow control floating ball is arranged to ensure that the flow limiting hole is always at a fixed height from the water surface no matter how much water is reserved in the water storage chamber, and the water flow entering the water service pipe through the flow limiting hole is ensured to be constant. Further, the time required from water storage in the water control tank to pouring is fixed and unchanged, so that the timing and quantitative automatic water supply of the irrigation pipe network is ensured by depending on a pure mechanical structure. Meanwhile, the vent hole can exhaust air, so that the water can be stably supplied downwards even if the flow limiting hole is small enough.
Further, the diameter of the vent hole is more than 4 times of the diameter of the flow limiting hole. So that the diameter of the vent hole is large enough to avoid the mutual blockage of the exhaust and the water flow from influencing the water amount flowing in through the flow limiting hole.
Furthermore, the lower part of the flow control floating ball is a solid floating ball body, the upper part of the flow control floating ball is a hollow floating ball cavity, the limiting hole is positioned on the floating ball body, and the vent hole and the floating ball cavity are isolated and sealed mutually.
Furthermore, the upper end of the flow control floating ball is also provided with a counterweight material inlet communicated with the floating ball cavity.
Therefore, the counterweight material can be added into the cavity of the floating ball through the counterweight material inlet, so that the draft of the floating ball is adjusted and changed, and the flow speed of water flowing into the water service pipe through the flow limiting hole is adjusted. And then can adjust every time water supply interval time as required, make its area size that adapts to the side slope better.
Thus, the working principle of the automatic irrigation control device is as follows: the floating ball can lift along with the rise and fall of the water level in the water storage chamber, and the depth of immersed water is kept unchanged, so that the water pressure of the flow limiting hole at 1/4 of the bottom surface of the water control floating ball is unchanged, and the stable control of the water quantity entering the vent hole through the flow limiting hole is realized; because the vent hole and the floating ball cavity are sealed and isolated from each other, water entering the vent hole cannot enter the floating ball cavity, and the buoyancy and the immersion depth of the floating ball are not influenced while the vent hole exhausts air upwards; the water entering the vent hole flows into the water control tank through the water pipe at the lower end of the floating ball; when the automatic irrigation device is used, the gravity center of the water control tank in the water-free state deviates from the water control tank support and is deviated to one side of the bottom of the water control tank, so that the tank opening faces upwards when the designed water amount of the water control tank is not reached, water flowing from a water pipe is accessed, the gravity center of the water control tank gradually moves towards the tank opening along with the increase of water in the water control tank, when the water amount reaches the designed water amount, the gravity center of the water control tank crosses the position of the water control tank support and moves to one side of the tank opening, so that the water control tank is toppled over, and after toppling over, the water control tank returns to the upward state of the tank opening, so that periodic timing and quantitative automatic irrigation is realized through repeated circulation.

And the mouth of the vent pipe is downward to prevent ground soil and stones from falling into the water storage chamber. In practice, the upper end of the vent pipe is preferably 50cm higher than the ground, so that the soil is prevented from splashing into the upper end of the vent pipe in rainy days.
In this embodiment, referring to fig. 1, 3-4, the irrigation system further comprises an automatic irrigation control device a-3 disposed between the water storage chamber and the irrigation pipe network, wherein the automatic irrigation control device is used for controlling the water storage chamber to supply water to the irrigation pipe network at regular time and quantity.
Therefore, the timed and quantitative water supply control of the processing pipe network can be realized, and the timed and quantitative irrigation effect is ensured.

Therefore, the reversible water control tank is arranged in the water control chamber, the center of gravity of the water control tank enables the tank opening to be upward when the water control tank is empty, the water stored in the upper water storage chamber is injected into the water control tank through the water outlet, and after the water injection exceeds a certain proportion, the tank opening of the water control tank is tilted downward and water is poured into the inlet of the main flow pipe of the irrigation pipe network. Thus, the pure mechanical structure is adopted to realize the quantitative control of rainwater entering the irrigation pipe network each time. An electric control valve is not needed, the restriction of power utilization is avoided, the reliability and the stability are better, and the service life is longer.
Wherein, the plane of the water control tank opening is arranged obliquely, and the plane of the tank opening is upward when the tank is in an empty state.
Like this, the hydroenergy of storage water tank can flow into in the accuse water tank better when making things convenient for the empty case state, and hydroenergy can pour the main current pipe inlet of watering pipe network in better when the accuse water tank is emptyd.
The water control tank comprises an external adjusting frame A-3-3 and a tank body arranged in the adjusting frame, the adjusting frame is integrally in a groove shape and is hinged to the upper end of a water control tank support, adjusting fixing screws horizontally penetrate through two sides of the adjusting frame, the adjusting fixing screws are rotatably screwed on the adjusting frame, the inner end of the adjusting fixing screws is abutted to the tank body to fix the tank body, and a balancing weight A-3-7 is inserted and connected to the bottom of the groove of the adjusting frame.
Like this, can be through changing the upper and lower position of box in the alignment jig to the cooperation increase and decrease balancing weight, adjust the flourishing water yield size of water control box when tumbling in its in a flexible way, make the water yield of pouring into in the watering pipe network at every turn can adjust to and the slope area size matches the correspondence better. When the water tank is specifically implemented, the middle part of the lower end of the adjusting frame is provided with a hinge shaft which is horizontally arranged and can be rotatably hinged at the upper end of the water tank control bracket by the hinge shaft. When the water control tank is installed, the water control tank can be opened upwards by adjusting the installation position and specific gravity, and forms an angle of about 15 degrees with the horizontal plane; when the water in the water tank is poured after reaching the designed water quantity, the opening faces downwards and forms an angle of about 15 degrees with the horizontal plane. Therefore, the water tank can be ensured to return to the state with the upward opening after the water is poured; and the circulation function of dumping after the designed water amount is achieved.
Wherein, a water pipe A-3-2 is arranged in the water storage chamber, and the lower end of the water pipe penetrates out of the water storage chamber downwards in a sealing way and extends to the upper part of the opening of the water control tank.
Therefore, rainwater in the water storage chamber can be accurately introduced into the water control tank by virtue of the water through pipe.
The water pipe A-3-2 is a hose, the length of the hose exceeds the height of the inner cavity of the water storage chamber, the upper end of the water pipe is connected with a flow control floating ball A-3-1 floating on the water surface, the part of the flow control floating ball submerged under the water surface is transversely provided with a flow limiting hole A-3-1c in a penetrating mode, the flow control floating ball is also vertically provided with an air hole A-3-1d in a penetrating mode, and the air hole is communicated with the flow limiting hole in a crossing mode; the lower end of the vent hole is communicated with the upper end of the water pipe in a sealing way.
Like this, the water in the water storage chamber can flow through the interior outflow of restriction orifice drainage water pipe to the accuse water tank in, and the restriction orifice can set up sufficient little so that the extension is held water in the accuse water tank and is toppled over once required time. The flow control floating ball is arranged to ensure that the flow limiting hole is always at a fixed height from the water surface no matter how much water is reserved in the water storage chamber, and the water flow entering the water service pipe through the flow limiting hole is ensured to be constant. Further, the time required from water storage in the water control tank to one-time pouring is fixed and unchanged, so that the timed and quantitative automatic water supply for the irrigation pipe network is ensured by depending on a pure mechanical structure. Meanwhile, the vent hole can exhaust air, so that the flow limiting hole can stably supply water downwards.
Wherein, the diameter of the vent hole A-3-1d is more than 4 times of that of the flow limiting hole A-3-1 c. So that the diameter of the vent hole is large enough to avoid the mutual blockage of the exhaust and the water flow to influence the water quantity flowing in through the flow limiting hole.
Wherein, the lower part of the flow control floating ball is a solid floating ball entity A-3-1a, the upper part is a hollow floating ball cavity A-3-1b, the limiting hole is positioned on the floating ball entity A-3-1a, and the vent hole and the floating ball cavity A-3-1b are mutually isolated and sealed.
Wherein, the upper end of the flow control floating ball is also provided with a counterweight material inlet communicated with the floating ball cavity.
Therefore, the counterweight material can be added into the cavity of the floating ball through the counterweight material inlet, so that the draft of the floating ball is adjusted and changed, and the flow speed of water flowing into the water service pipe through the flow limiting hole is adjusted. And then can adjust every water supply interval time as required, make its area size that adapts to the side slope better.
Thus, the working principle of the automatic irrigation control device is as follows: the floating ball can lift along with the rise and fall of the water level in the water storage chamber, and the depth of immersed water is kept unchanged, so that the water pressure of the flow limiting hole at 1/4 of the bottom surface of the water control floating ball is unchanged, and the stable control of the water quantity entering the vent hole through the flow limiting hole is realized; because the vent hole and the floating ball cavity are sealed and isolated from each other, water entering the vent hole cannot enter the floating ball cavity, and the buoyancy and the immersion depth of the floating ball are not influenced while the vent hole exhausts air upwards; the water entering the vent hole flows into the water control tank through the water pipe at the lower end of the floating ball; when the automatic irrigation device is used, the gravity center of the water control tank in the water-free state deviates from the water control tank support and is deviated to one side of the bottom of the water control tank, so that the tank opening faces upwards when the designed water amount of the water control tank is not reached, water flowing from a water pipe is accessed, the gravity center of the water control tank gradually moves towards the tank opening along with the increase of water in the water control tank, when the water amount reaches the designed water amount, the gravity center of the water control tank crosses the position of the water control tank support and moves to one side of the tank opening, so that the water control tank is toppled over, and after toppling over, the water control tank returns to the upward state of the tank opening, so that periodic timing and quantitative automatic irrigation is realized through repeated circulation.
Referring to fig. 1 and 5, the irrigation pipe network a-4 comprises a main flow pipe a-4-1 arranged downwards along the slope surface of the side slope, a water inlet at the upper end of the main flow pipe is connected with an automatic irrigation device (specifically connected with the bottom of the water control chamber), branch flow pipes a-4-3 are arranged on the main flow pipe at intervals in a communicating manner, the branch flow pipes are horizontally arranged along the side slope and are embedded in the plant growth base material, and water seepage holes a-4-3a are arranged on the branch flow pipes at intervals.
Like this, automatic watering device is in time quantitative during the watering and is supplied the watering water to the mainstream intraductal, through each tributary pipe and the infiltration hole on it, directly the infiltration enters into in the plant living substrate, can avoid the evaporation of water better, has improved the utilization effect to the water resource.
Wherein, a plurality of shutoff type water outlets A-4-2 are arranged in the main flow pipe A-4-1 at intervals from top to bottom; the intercepting type water outlet A-4-2 comprises a water outlet joint A-4-2b communicated with the main flow pipe, the lower side edge of the joint of the water outlet joint and the main flow pipe extends to the oblique upper part of the inner cavity of the main flow pipe to form a sheet-shaped water receiving bulge, and the edge of the water receiving bulge and the inner cavity of the main flow pipe are encircled to form an intercepting groove A-4-2a; the outer end of the water outlet joint is fixedly connected with the branch pipe.
Therefore, in the application, the irrigation is performed at regular time and quantity in each time, and the problems that the irrigation close to a water source is sufficient and the irrigation at the tail end of a pipe network is insufficient due to long-time small-flow irrigation are solved. The regular and quantitative irrigation has the characteristics of large water volume and short time, and if the conventional irrigation pipe network is arranged, the equivalent irrigation of branch pipes with different heights on the same main flow pipe cannot be realized. Therefore, the interception type water outlet structure is arranged in the application. When the main flow pipe supplies water quantitatively each time, the water supplied quantitatively flows downwards from the main flow pipe, and each branch flow pipe is intercepted actively by the intercepting groove to smoothly and rapidly introduce the water into each branch flow pipe, so that the water supply effect of each branch flow pipe is ensured. Meanwhile, the structure can ensure the balance of water amount accessed by the branch flow pipes at different heights by adjusting the size of the intercepting groove, thereby providing a balanced irrigation effect.
Wherein, the upward inclination angle of the water receiving bulge is about 45 degrees.
Therefore, the water retaining device can ensure a better water retaining effect and has better structural strength to avoid being quickly damaged by water flow scouring.
The intercepting water outlets A-4-2 are arranged on the dry flow pipe at intervals from top to bottom and from left to right.
Therefore, the uniformity of the water quantity intercepted by each branch pipe is improved.
Wherein, the end part of the water inlet end of the branch pipe is bent or inclined upwards and then is connected to the water outlet joint.
Therefore, the intercepted irrigation water is more conveniently led into the branch flow pipes by the intercepting type water outlets.
Wherein, the height that the branch pipe intake end tip upwards bends or inclines is 50cm. Irrigation water can be better introduced into the branch pipes.
In this embodiment, the intercepting area of the intercepting groove of each intercepting type water outlet gradually increases from top to bottom along the main flow pipe.
In this way, the simultaneous water interception of the branch pipes can be better realized under the condition of timing and quantitative irrigation. The water inflow time of the main flow pipe is the same, so that the water inflow intercepted by each branch flow pipe is equal. And the irrigation water in each branch flow pipe flows in at the same time, so that the irrigation uniformity of the whole irrigation pipe network can be better improved.
As another practical structure mode, the edge of the water receiving bulge in each intercepting type water outlet is in a semi-elliptical shape as a whole, and the diameter of the short side is the same as the inner diameter of the main flow pipe, so that the intercepting groove occupies half the cross-sectional area of the main flow pipe.
By adopting the structure mode, a pair of branch flow pipes which are opposite to each other at the left and right sides in the middle upper part of the main flow pipe can intercept pouring water and fill the pouring water, and then overflow from the interception type water outlet to flow downwards. So that the branch pipes with different heights are filled with water one by one from top to bottom. This has the advantage of facilitating more accurate calculation and control of the amount of water required for each pour. The defects are that the upper main flow pipe is filled with water firstly, the irrigation is often longer, the irrigation uniformity is influenced, and the irrigation uniformity can be improved by adjusting the way that the distance between the adjacent main flow pipes is gradually reduced from top to bottom.
In this embodiment, the diameter of the main flow pipe is about 10cm, and the diameters of the water outlet joint and the branch pipe are about 5 cm. Better guarantee the drainage watering effect.
Wherein, be provided with the water guide layer of a strong capillary action in the vegetation substrate, the tributary pipe is buried in the water guide layer position underground.
Thus, the irrigation water which is easy to permeate from the water seepage holes of the branch flow pipes can slowly permeate to the whole side slope through the water guide layer to realize irrigation.
In the embodiment, the water guide layer is obtained by adopting a geotechnical blanket, and the branch pipes are wrapped in the geotechnical blanket.
The geotechnical blanket capillary effect is excellent like this, can realize evenly distributed water better, and the tributary pipe parcel can play good protection effect in it simultaneously, avoids in the soil worm or silt etc. to get into and destroy the tributary pipe.
Wherein, the tail end of the branch flow pipe A-4-3 is provided with an exhaust pipe A-4-4 which extends upwards to form the plant growing base material and is communicated with the atmosphere.
Can make things convenient for the lateral flow pipe entry end to introduce the watering water of holding back more smoothly like this through the quick exhaust of blast pipe to make the watering water of entering lateral flow pipe fill whole pipeline rapidly, then rely on the infiltration hole to slowly ooze water realization watering again. The defects that the watering effect is good when one end of the main flow pipe is close to and the watering effect is poor when one end of the main flow pipe is far away from are overcome. The uniformity of irrigation is better ensured.
Wherein, the blast pipe upper end is the downward bending setting.
The blockage caused by the fact that mud or sundries enter the exhaust pipe can be better avoided.
When the device is implemented, the height of the upper end of the exhaust pipe is higher than that of the shutoff type water outlet corresponding to the branch pipe. The waste of irrigation water flushed from the exhaust pipe can be better avoided; the height of the exhaust pipe can be about 1 m during implementation. When the exhaust pipe is used, the diameter of the exhaust pipe can be 1cm, the exhaust requirement can be met, and impurities can be better prevented from entering.
In the implementation, a better choice is that the lower edge pipe wall of the branch pipe A-4-3 is provided with a water seepage hole A-4-3a at intervals of 15cm, so that the slope surface in the whole branch pipe range can be uniformly irrigated.
In this embodiment, referring to fig. 6-11, the anchoring system B includes a plurality of rib belt nets B-6 arranged transversely along the slope, a space for stacking plant growth substrates is formed above the rib belt net, two sides of the rib belt net are fixed on anchor cables B-5 arranged vertically along the slope, and upper ends of the anchor cables are fixed on anchor piles B-1 at the top of the slope.
Thus, the transversely arranged reinforcing mesh bears the gravity of the plant-growing base material on the side slope, and the gravity is transferred to the anchor piles at the top of the side slope through the anchor cables. Therefore, the anchor pile is constructed at the top of the side slope more conveniently, simply and safely, the anchor pile can be constructed more deeply to bear larger tensile force, and meanwhile, compared with the mode that a vertical anchor pile is arranged on the side slope, the anchor pile at the top is vertically arranged to bear oblique downward tensile force, so that the anchor pile is more difficult to be cast off, and the anchor rope can generate pressure towards the inside of the side slope to maintain the stability of the slope rock mass; the slope surface of the side slope is not required to be deeply drilled with anchor holes, so that the self structural stability of the side slope is maintained. Therefore, the plant growth base material on the side slope can be fixed more conveniently, quickly, efficiently and reliably, and the reliability of ecological restoration is improved.
Wherein, the anchor rope sets up in groups, and every group is provided with two anchor ropes, and two anchor ropes set up along the plane interval of perpendicular to side slope, all along the edge slope height direction interval between every two sets of adjacent anchor ropes and be provided with a plurality of muscle area nets, and the inside and outside both ends of muscle area net both sides are fixed respectively on two anchor ropes of every group.
Therefore, each group of two anchor cables can facilitate the installation and the bearing of the rib belt net, and the anchor cables and the rib belt net divide the slope into a plurality of corresponding grid spaces, so that an effective three-dimensional flexible force transmission structure is formed on the slope surface; the plant growth materials stacked in each space bear the gravity by the aid of the rib belt nets and act on the double-layer anchor cables on the two sides, and then are transmitted to anchor piles on the top of the slope through the double-layer anchor cables, so that the pressure of the plant growth base materials of the upper grid space units on the plant growth base materials of the lower grid space units is very small and cannot be influenced by the slope height, and the height of the slope plant growth base materials is not limited by the slope height; can better realize the fixation of the plant growth material.
The anchor cable is preferably made of high-strength steel cable to better guarantee the strength.
The reinforcement belt net is composed of reinforcement belts B-6-1 and positioning reinforcements B-6-2 at two ends, the reinforcement belts are horizontally arranged on the slope, and the positioning reinforcements B-6-2 at two ends of the reinforcement belt net are connected with double-layer anchor cables B-5 at two sides through anchor cable buckles B-5-1.
Therefore, the installation, connection and fixation of the rib belt net can be facilitated, the fixation reliability between the rib belt net and the anchor cable can be better ensured, and the rib belt B-6-1 is prevented from being separated from the anchor cable under the action of the gravity of the plant-growing material.
In the embodiment, the length of the rib belt net B-6 is about 2m, the width is about 23cm, and the interval of the rib belt net B-6 in the slope surface vertical direction is about 1.5 m. Therefore, the plant growing material in the grid unit where each rib belt net is located has moderate gravity, and the stability and the reliability of integral fixation are ensured.
In this embodiment, in each group of anchor cables, the anchor cable close to the inner part is away from the bottom of the slope surface by a certain distance.
So because plant and grow the most nexine in the substrate and be the soil dressing layer, so this structure can be when guaranteeing that the muscle area net is to the fixed effect of keeping of living substrate, leave a section of interval distance between muscle area net and domatic bottom for domatic bottom is piled up and is planted the soil dressing layer that is located the bottom in living substrate and can be linked into one piece, makes things convenient for plant growth's root system to get into can tightly grasp side slope rock surface better after the soil dressing layer and extend the growth one-tenth. And then can rely on plant roots to better improve the stability of whole slope greening system structure after the plant grows out. This distance is preferably 2cm, which makes it possible to optimize the effect described above.
The top edge position of the side slope corresponding to each group of anchor cables is also provided with a guide pier B-2, guide limiting holes B-2-1 penetrate through the guide pier along the front-back direction, and the upper ends of the anchor cables penetrate through the guide limiting holes and then are fixed on the anchor piles backwards.
Therefore, the anchor cables are guided by the guide piers to change the direction and then are connected with the anchor piles, the guide piers can arrange all groups of anchor cables at different positions of the slope top according to design, force bearing and force transmission are better realized, partial anchor cable tension can be decomposed and offset, and the stability and reliability of the whole anchoring system are better improved. When the anchor cable guide device is implemented, the guide piers are arranged at intervals of about 2m and are consistent with the intervals of two adjacent anchor cables.
The guide pier is a reinforced concrete pier and is embedded and fixed in the slope top bedrock, steel pipes are embedded in the top and the middle lower part of the guide pier respectively along the front and back direction, and guide limiting holes B-2-1 of the guide pier are formed in inner holes of the steel pipes.
Thus, the construction and arrangement of the guide pier are facilitated. During implementation, a steel pipe with the inner diameter about 1.1 times of the diameter of the designed anchor rope is preferably adopted, so that the anchor rope can conveniently pass through the steel pipe.
Wherein, the anchor pile B-1 is a section steel concrete pile, the pile body of the anchor pile is embedded and fixed in a rock stratum with stable slope top, the pile top and the middle-lower part (preferably about 20cm away from the ground) of the anchor pile are respectively provided with an anchor cable hole B-1-2 which is through from front to back and is inclined, and an anchor B-1-1 is arranged in the anchor cable hole B-1-2 and is used for fixing an anchor cable.
Therefore, the self structural strength of the anchor pile can be better ensured, the bearing effect on the anchor cable is ensured, and the gravity load of the slope plant-growing base material transmitted by the anchor cable is borne.
A row of positioning rods B-3 are further vertically arranged on the slope surface where each group of anchor cables are correspondingly arranged at intervals, the lower ends of the positioning rods are fixed to the slope surface, positioning holes B-3-1 are arranged in the top and middle of each positioning rod in a penetrating mode along the direction of the anchor cables, and the anchor cables can slidably penetrate through the positioning holes.
Like this, because the pulling force of anchor rope is born by the anchor stake, the locating lever does not bear plant living substrate gravity basically, and the locating lever effect is mainly kept the anchor rope and arranges according to required position and interval. Therefore, the lower end of the positioning rod only needs to be fixed to the slope surface shallowly, and the slope surface structure is not damaged by drilling a deep anchoring hole on the slope surface. Therefore, the construction is convenient, and the overall stability of the system can be better improved.
During implementation, the better size parameter selection is that the distance between every two positioning rods is about 2-3m, the length of each positioning rod outside the slope rock wall is about 30cm, the positioning holes in the middle lower parts of the positioning rods are arranged about 2cm away from the slope, and the inner diameter of each positioning hole is about 1.1 times of the diameter of the designed anchor cable. The positioning effect can be optimized.
And the bottom of the side slope below each group of anchor cables is also provided with an anchor rod B-4, the lower end of the anchor rod is anchored in a rock stratum at the bottom of the side slope obliquely downwards, and the bottom of each anchor cable is fixedly connected to the anchor rod through an anchor cable buckle and is in a prestress state of applying pressure to the positioning rod to the slope body.
Like this, the setting of stock for both ends are by the tensioning about the anchor rope and are the prestressing force state of inside applied pressure, make the locating lever inwards compress tightly like this, are difficult for droing more, can improve whole anchoring system's stability and reliability better.
Thus, after the anchoring system is arranged, each group of vertical anchor cables B-5 and horizontal rib belt nets B-6 form an effective three-dimensional flexible force transmission structure on the high and steep rocky slope, when the plant growth base materials are laid on the high and steep rocky slope, the gravity of all the plant growth base materials is transmitted to the vertical double-layer anchor cables B-5 through the rib belt nets B-6 and then transmitted to the anchor piles B-1 on the top of the slope through the double-layer anchor cables B-5, and therefore the top anchor type plant growth base material fixing system (namely the anchoring system) is formed. Because the top anchor type plant growth substrate fixing system divides the slope plant growth substrate into a plurality of units of 2m multiplied by 1.5m, the units are mutually independent, and the gravity of each unit is transferred to the anchor pile at the top of the slope by the pulling force of the anchor rope to balance, so that the pressure of the plant growth substrate of the upper unit on the plant growth substrate of the lower unit is very small and cannot be influenced by the slope height, the height of the slope plant growth substrate is not limited by the height of the slope, and the thickness of the plant growth substrate can be kept unchanged along the whole slope height; meanwhile, the damage of a single unit only has little influence on the adjacent lower unit, so that the integral collapse disaster of the vegetation base material cannot happen; in addition, compared with a slope stressed anchor rod of a three-dimensional plant spraying technology, the top anchoring type plant growth base material fixing system is not acted by the downward gravity of the plant growth base material on the locating rod of the slope, so that the distance between the fixing points is large, the requirement on the embedding depth is low, the high-risk workload of a high and steep rocky slope can be greatly reduced, and the construction difficulty and the safety are effectively improved; moreover, the double-layer anchor cable B-5 can apply a force which is perpendicular to the slope surface and inwards through the positioning rod, so that the stability of the rock slope surface cannot be adversely affected, and the stability of the slope surface can be effectively improved.
In this embodiment, referring to fig. 12 to 15, the plant growth substrate C includes a water-holding soil layer C-1 laid on the bottom surface of the side slope, and a plant growth layer C-3 disposed above the water-holding soil layer, the plant growth layer contains plant seeds, a water retention layer C-4 is further disposed above the plant growth layer, and at least one layer of gravel material is disposed in the water retention layer.
Therefore, the water holding guest soil layer C-1 is connected with the rocky slope, has good water absorption and strong water holding capacity, and is mainly used for storing water irrigated by the rainwater harvesting irrigation system A on the rocky slope to provide long-term stable water for vegetation growth of the rocky slope, and after plant seeds in the vegetation layer germinate, root systems roll into the water holding guest soil layer to absorb water and grow nutritionally. Meanwhile, the water retention layer mainly formed by the breccia material is arranged, so that the advantage of weak capillary action of the breccia material can be utilized, the water evaporation is better avoided, and the water retention maintenance is realized. Is more beneficial to the growth and the restoration of the vegetation on the side slope. In the implementation, the thickness of the water-holding foreign soil layer is preferably about 10cm, so that the effect can be better ensured.
In the embodiment, the water-holding soil dressing layer is prepared by spraying a three-dimensional net. Has the characteristics of simple, convenient and quick construction, and is more suitable for areas with relatively sufficient construction water.
As an alternative to this embodiment, the water-holding soil layer is obtained by stacking soil-carrying bags. Has the characteristic of low cost and is more suitable for areas with relatively less construction water.
In the embodiment, a water guide layer C-2 with strong capillary action is also arranged between the water holding layer C-1 and the vegetation layer C-3.
Therefore, the water guide layer can uniformly distribute the irrigated water to the water holding foreign soil layer on the whole slope surface, and the irrigation effect is better ensured. Meanwhile, the arrangement of the water guide layer can effectively increase the distance between the upper and lower adjacent pipelines of the horizontal branch flow pipe for irrigation, reduce the using amount of the branch flow pipe and reduce the engineering cost.
Wherein, the water guide layer is obtained by laying a geotechnical blanket. The water guide device has the advantages of low cost, easiness in implementation, good water guide effect and the like.
Wherein, the winding is provided with the tributary pipe that is used for the watering in the geotechnological blanket. Therefore, water poured by the branch pipes directly passes through the geotechnical blanket water guide layer, so that the water is uniformly distributed on the slope surface, and the pouring uniformity is better improved. Meanwhile, the branch pipe is protected, and the service life of the branch pipe is prolonged.
In practice, the thickness of the geotechnical blanket is preferably about 1 cm. If the thickness is too thin, the water distributing and guiding effect is not good, and if the thickness is too thick, the water conducting range and the plant root growth are easily influenced.
In practice, the plant growing layer can be prepared by mixing plant growing material with plant seeds, stirring and pressing, and the thickness is about 8 cm.
