Abstract
The utility model discloses an ecological slope protection component of anti-erosion substrate pertaining to the field of slope protection project, ecological restoration project and greening project which is mainly composed of a substrate layer, a reinforced layer and an anti-erosion layer. Wherein, a reinforced screen and anchor bolts are equipped on the reinforced layer. The utility model provides better growth environment of slope plants through the interaction of the substrate layer, reinforced layer and anti-erosion layer, prevents spraying explants layer of slope surface from cracking, and has a strong ability of water erosion resistance, which is not only suitable for the protection and ecological restoration of railway slope, road slope, abandoned mine slope and river channel embankment having slope gradient less than 50 degrees, but also used for the ecological restoration of slow slope position of reservoir riparian zone. The utility model has the advantages of that the ecological slope protection component is simple in production process and manual based, only a small amount of mixers and anchoring shifts are needed for the mechanical equipment and less occupancies are needed in construction site.
Description
Technical field
The utility model relates to and a kind ofly is applied to slope protection works, ecological recovery engineering and to the used anti-scouring substrate ecological slope protecting components of afforestation project.
Background technology
At present domestic side slope protection greening method commonly used mainly contains: plant give birth to band greening, hydraulic pressure sow grass seeds by duster plant think of a way, the thick-layer base material sprays or TBS greening technique and plant cover concrete slope protection greening technology etc.Wherein planting to give birth to is with greening only to be applicable to soil-slope or soft rock side slope; Hydraulic pressure is sowed grass seeds by duster, and planting thinks of a way only is applicable to slow soil-slope; The thick-layer base material sprays or the TBS greening technique combines that hydraulic pressure is sowed grass seeds by duster and the advantage of alien earth sparging technology, though can be applied to rock slope, has that intensity is low, water retention property is poor, drought susceptible shortcoming.Though plant cover concrete slope protection greening technology intensity height, water retention property better and be applicable to various soil properties, soft rock, hard rock and concrete side slope, mainly are to be used for high gradient slope, cost is higher.Therefore, though can solve the greening problem of the gradient, can not satisfy slope ecological recovery and the bank protection function combines, ability to resist splash erosion is strong, construction cost is cheap, applicability is wide requirement fully less than 50 degree side slopes with these methods.
Summary of the invention
The purpose of this invention is to provide a kind of be implemented in the gradient less than 50 the degree side slopes on can prevent that rainwater washes away, not chapping has the bank protection function, can satisfy side slope (comprising soil-slope, salt-soda soil side slope, soft rock side slope, hard rock side slope, concrete side slope) ecological recovery requirement again, and the anti-scouring substrate ecological slope protecting components of relative low price.The anti-scouring substrate ecological slope protecting components is called for short PEB (A ecologicalslope-protected component of Preventing Erosion Basismaterial).
The purpose of this utility model is achieved in that a kind of anti-scouring substrate ecological slope protecting components, comprises substrate layer 1, is reinforcement layer 2 on the substrate layer 1, reinforcement layer 2 is made of reinforcement net 4, reinforcement net 4 is provided with holdfast 5, and holdfast 5 passes substrate layer 1, is erosion control brush layer 6 on the reinforcement layer 2.Erosion control brush layer 6 is made of plant cover concrete.Reinforcement net 4 is wire gauze or geonet.
Anti-scouring substrate ecological slope protecting components provided by the utility model, interaction by substrate layer, reinforcement layer and erosion control brush layer, can provide growing environment preferably for slope plant, keeping the spray of side slope surface to plant layer does not chap, anti-rain drop erosion bank protection ability is strong, be not only applicable to protection and the ecological recovery of the gradient, can be used for the restoration of the ecosystem at the slow position of reservoir drawdown band yet less than 50 railway slopes of spending, slope of highway, abandoned mine side slope, rivers channel embankment; The utility model manufacture technology is simple, and based on manually-operated, plant equipment only needs a spot of mixer and spray windlass machine-team, and the construction plant is taken up an area of less.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model reinforcement layer plane structure chart.
The specific embodiment
The structure of anti-scouring substrate ecological slope protecting components divides three layers to be substrate layer 1, reinforcement layer 2 and erosion control brush layer 3.Detailed structure and to manufacture process as follows: substrate layer 1 thickness is 7-8 centimetre and can adjusts according to actual conditions, substrate layer 1 is by humus soil, rice husk, composite fertilizer constitutes with an amount of pesticide in 3: 0.8: 0.001 ratios, the soil nutrient and the porosity of whole substrate layer have been guaranteed, for providing, the good growth of vegetation lays a good foundation, the reinforcement net 4 of reinforcement layer 2 is layed in substrate layer 1 top, can adopt No. 14 wire gauze or geonet, and take advantage of 1 meter four jiaos to add holdfast 5 by 1 meter at the reinforcement wire side, holdfast 5 can adopt Φ 16 reinforcing bars, holdfast 5 length are determined according to domatic basis, make the ecological revetment layer be linked as integral body, strengthen the stability of substrate layer.Again on 2 on reinforcement layer, spray 2 cm thicks and have containing of 0.4 MPa intensity and mix the erosion control brush layer 3 of planting green seed, the erosion control brush layer can adopt 0113843.7 green additive for concrete plant cover concrete to spray and form.Can effectively prevent rain drop erosion, under the heavy rain condition of 120mm/h, erosion control brush layer 3 the soil losses phenomenon can not occur, and does not chap; Green germination growth is planted in the mixing that contains, and reaches the ecology recovering purpose.
This ecological slope protecting components has good plant growth environment and nutrient and water self-restraint ability and whole preferably bank protection function.When particularly plant root growth is distributed in substrate layer and takes root in sloping base, its whole bank protection function will be more stable.
Concrete execution conditions:
Grade of side slope＜50 degree;
Substrate layer: 7-8 centimetre, can be according to the vegetation root system length adjustment of growing;
Holdfast length is not as the criterion so that holdfast is loosening, exposes 1 centimetre of base material aspect;
Holdfast spacing＜1 meter;
The reinforcement net is taken knot width: 10-15 centimetre;
Erosion control brush layer (plant cover concrete layer) thickness: 2 centimetres.
The utility model implementation step is: 1, side slope is carried out suitably clear slope, reach roughly smooth.2, construct by the form of structure and the material of anti-scouring substrate ecological slope protecting components.3, the shop nonwoven preserves soil moisture.4, to the domatic maintenance of sprinkling water, vegetable seeds will germinate after 5-7 days, will manifest the slope protection greening effect in one month.
