Description
Technical field
The invention belongs to hillside fields irrigation technique field, it is related to a kind of hillside fields rainwater-collecting gravity irrigation system and its to apply on the spot
Work method.
Background technology
Hillside fields irrigate conventional method be exactly collect and save using intercepting drain and water cellar rainwater or south frequently with
Pond on a hill retaining, then using the method for pump irrigation by pumping.Water cellar has the advantages that its material price is cheap, but also has a disadvantage that：
(1) intercepting drain is bright ditch, and it is larger to take up an area more, larger to the vegetation deterioration in hillside fields, influence to facilities such as roads,
And flood enters the silt that ditch brings and easily silts ditch and water cellar up.Setting pot is such as set, then except wanting design arrangement, this is consolidated
Determine outside facility, but also periodic cleaning, maintenance and management are carried out to it.
(2) when locality is without impermeable soils such as yellow mud must using the heavier construction material such as sandstone cement, carry because of mountain region and
Constructional difficulties and it is time-consuming take a lot of work, cost also accordingly increases, and in price of labour power area higher, expense increases more.
(3) when there are the impermeable soils such as yellow mud locality, though cost is cheap because the strength of materials is poor fragile, maintenance relatively frequency
It is numerous.
(4) intercepting drain and water cellar position are relatively fixed, and need to build setting pot, and be difficult adjustment and reorganization and expansion.
(5) traditional cistern system water saving irrigation facility without run-on.
Pond on a hill adds the method for irrigation by pumping also to have many shortcomings, such as：
(1) often seepage is more serious for pond on a hill, and Anti-seeping technology is done to whole pond on a hill, invests very big.
(2) irrigation by pumping needs to build pump house and water tower, and investment is big, and water pump operation needs power consumption power, along with installations and facilities pipe
Reason, cost is very high, and the place that many hillside fields do not reach for electric power, and irrigating by lifting water to a higher level with a water pump, etc. to implement.
(3) pond on a hill adds the pattern irrigated by lifting water to a higher level with a water pump, etc. to still need water-supply-pipe/canal more long, further steps up its investment.
The content of the invention
In order to overcome defect present in prior art, the present invention to provide a kind of hillside fields rainwater-collecting gravity irrigation system on the spot
System and its construction method, solve the problems, such as southern mountain forest ground, the rainwater-collecting on Gentle hillside ground and irrigation on the spot.Slope runoff generation
Characteristic be that flood comes anxious, goes soon, if the storing facilities of water that drains off floodwaters does not catch up with, to the inereasing water area of rainwater not enough, hillside fields footpath
In violent scour earth's surface, while causing serious water and soil resources to be lost in, Slopeland Agriculture but may all occur drought to stream in each season
Feelings.Gravity irrigation system is designed neoteric rainwater-collecting in order to solve this contradiction on the spot.If mountain forest ground and
Gentle hillside ground plantation water requirement less drought-enduring plant or forest, can be using the system as iirigation water source；If plantation is needed
The more plant of water, mountain vegetables such as, the system can act also as supplement irrigation water source.By the systematic difference, can be with
Unbalanced natural precipitation accumulation is distributed space-time, at one's command, the efficient water resource for utilizing is converted into, gentle slope ground
It is changed into irrigating the fields, for the irrigation of gentle slope ground drought-resistant agriculture provides advantage.Its technical scheme is as follows：
A kind of hillside fields rainwater-collecting gravity irrigation system on the spot, including water guide film, collection rain covered conduit, filter pipe, water storage film bag
And water-saving irrigation pipe, water guide film be laid on collection rain covered conduit bottom and both sides, collection rain covered conduit along contour slow down slope arrange, collection rain it is dark
Filter pipe is placed in ditch, filter pipe is connected with water storage film bag, the device on water storage film bag with release medicine, water storage film bag bottom
Delivery port is provided with, top is provided with passage.
Preferably, the drainage tube wall is knitted using cheap, light weight, product diversification degree geotextiles very high or geotechnique
Thing.
Preferably, the filter pipe can be directly connected to one section or one section of PE of overcoat when the barriers such as road, gully are passed through
Pipe.
Preferably, the water storage film bag is using red soil film bag.
A kind of construction method of hillside fields rainwater-collecting gravity irrigation system on the spot, comprises the following steps：
1) ditching：Gesture excavates collecting gutter along contour near the mountain, bottom of trench should have certain slope, typically 1/1000~1/
Between 3000, section can scrape out U-shaped, and size is advisable with that can pass through intercepted slope runoff under corresponding base slope and roughness.
Hillside middle and upper part can be selected into " Y " font arrangement collecting gutter upper-part centralized rain face in sector.Collecting gutter arc length, radius and collection
Rain area can be designed according to the water requirement of local standard rainfall intensity, crop or nursery stock, also will be with the appearance of water storage film bag
Amount size matches.
2) plastic film mulch：To prevent seepage, membrane material preferably selects the geomembrane for meeting environmental requirement to bottom of trench plastic film mulch, such as local soil property
It is soft but and without sharp stone, can directly tamp collecting gutter bottom, then lay geomembrane.As contained sharp in local soil property
Stone, preferably does a transition bed course in bottom of trench and furrow bank, and geomembrane is laid after compacting.
3) put and manage and fill：Collector pipe is placed in collecting gutter having dug, is filled with without the permeable earth material of sharp stone.Landfill
Overlying earth material thickness is that wind and rain drop erosion are exposed to require to be difficult, typically no less than 20mm.
4) joint and leaping over obstacles：Collector pipe and plastic film mulch can be by the extensions that continues, the method that joint can be using overlapping,
Plastic film mulch has a section film with leading portion mould, and collector pipe covers back segment with back segment, and the lap of splice is advisable with 10cm, and uses transparent adhesive tape adhesion.
5) it is fixed：To prevent water storage bag along hillside fields skid, preferably using iron wire or rope by water bag be fixed on rock, big tree or
On the anchor point of underground, or it makes relatively firm pedestal.
Beneficial effects of the present invention：
The present invention solves the problems, such as southern mountain forest ground, the rainwater-collecting on Gentle hillside ground and irrigation on the spot.Slope runoff generation
Characteristic be that flood comes anxious, goes soon, if the storing facilities of water that drains off floodwaters does not catch up with, to the inereasing water area of rainwater not enough, hillside fields footpath
In violent scour earth's surface, while causing serious water and soil resources to be lost in, Slopeland Agriculture but may all occur drought to stream in each season
Feelings.Gravity irrigation system is designed neoteric rainwater-collecting in order to solve this contradiction on the spot.If mountain forest ground and
Gentle hillside ground plantation water requirement less drought-enduring plant or forest, can be using the system as iirigation water source；If plantation is needed
The more plant of water, mountain vegetables such as, the system can act also as supplement irrigation water source.By the systematic difference, can be with
Unbalanced natural precipitation accumulation is distributed space-time, at one's command, the efficient water resource for utilizing is converted into, gentle slope ground
It is changed into irrigating the fields, is that gentle slope ground drought-resistant agriculture and the irrigation for planting organic mountain vegetables provide advantage.
