Abstract
The present invention provide a kind of geotechnical grid and its slope surface it is multiple it is green in application, the geotechnical grid is made of ecological non-woven fabrics.The raw material of the ecology non-woven fabrics uses polypropylene short fiber.The raw material of the ecology non-woven fabrics uses the fineness of polypropylene short fiber for 4-8D, length 60-85mm.15 ~ 21 cm of bending resistance length, water repellency: static contact angle > 120 °.Geotechnical grid of the present invention has good water suction, storage capacity on the basis of solid soil thickness reaches 30-45cm, so that the water-holding capacity of slope surface is improved 2 times or more, reduces the water of precipitation side slope washed away.Meanwhile geotechnical grid of the present invention can it is intercepted with slow release moisture, the green plants growth in side slope provides more moisture, also extends water supply time.
Description
Technical field
The present invention relates to bank protecting methods, and in particular to a kind of geotechnical grid and its application in slope surface is green again belong to ring
Border protection technique field.
Background technique
Traditional geotechnical grid is to be formed by high-intensitive HDPE or PP copolymerization material broadband by strongly welding or riveting
A piece of netted cell compartment structure.It is capable of expansion and contraction, and when transport, which can contract, to gather into folds, and when use opens and fills native stone or concrete again
Material constitutes the structural body with powerful laterally limiting and big rigidity.
In slope surface is green again, geotechnical grid slope vegetation protection is most common two classes: one kind is assembled by TGXG
The geotechnical grid of composition；Another kind of be made of high strength tapes polymer.
The geotechnical grid of the prior art constantly enhances the intensity of itself to realize preferably solid native effect；Traditional soil
While work cell compartment intensity increases, flexibility will be reduced, and therefore, Gu the geotechnical grid that native effect is good, pliability is all poor, all
It is the product of sizing, shape cannot be changed with the fluctuating of landform；In order to be bonded geotechnical grid with slope surface, needing will be at slope surface
Plane, then construction and installation geotechnical grid are managed into, is taken time and effort in this way, project amount is big.
The geotechnical grid of the prior art there is also can not absorb water, water storage the problem of；Due to filling soil ability in geotechnical grid
Afforestation vegetation can be planted, but rain drop erosion is lost soil from the bottom of geotechnical grid, and vegetation is caused slowly to lose existence
Basis.If moisture, storage moisture can be absorbed in geotechnical grid, rainwash dynamics can be substantially reduced, meanwhile, it can be with
Moisture is provided for plant growth.But geotechnical grid in the prior art does not have water suction, storage capacity.Also the technical staff having
Trial common non-woven fabric or blotting paper make geotechnical grid, but often intensity difference, easily broken after its water suction, lose solid native energy
Power.
Side slope protection side of the existing patent document CN201510287309.8 based on geotechnical grid and fibrous clay mixture
Method and structure, comprising the following steps: (1) smooth side slope surface is laid with geotechnical grid in slope surface；(2) clay is crushed, then
Addition mesh polypropylene-fibre, fertilizer and water are stirred, until mixture is in liquid-plastic state；(3) by mixture laying on side
In the slope surface of slope, and smooth out；(4) it sows grass seeds by duster grass seeds in side slope surface, then covering curing geomembrane, then carries out nourishment.The hair
It is bright for improve geotechnical grid intensity, material using reinforcing high density polyethylene sheet material；It cannot rising with landform
It lies prostrate and changes shape, also do not have the effect of water suction, water storage.The improvement side of patent CN201510192976.8 Rocky Desertification
On the one hand method is used directly for Rocky Desertification Region water and soil guarantor in such a way that geotextile and geotechnical grid are used in combination
It holds, creates conditions for large area afforestation, vegetation is on the other hand planted in geotechnical grid, rebuild the ecosystem；With terylene
For the synthetic staple fibers needling nonwoven geotextiles of raw material production；Layer overlay is filled out on geotextile contains water-retaining agent and nutritional agents
Soil.The geotechnical grid that the invention is related to is traditional geotechnical grid, and solid-holding capacity is not strong, does not also have water suction, water storage
Function.
To sum up, prior art geotechnical grid can not overcome simultaneously following defect:
(1) solid-holding capacity is poor, Gu soil thickness is difficult to reach 15cm or more；
(2) material is hard, and shape cannot change with concave-convex rise and fall of landform, needs slope surface treatment into smooth side slope, then
It could construct；
(3) do not have water suction, water-holding capacity.
Summary of the invention
The present invention provides a kind of geotechnical grid and its applications in slope surface is green again, to reach following goal of the invention: (1)
Geotechnical grid is set to reach 30cm or more to the solid soil thickness of slope surface soil moved in improve the original；
(2) pliability for improving geotechnical grid, is applied in rough side slope, can change shape with the fluctuating of landform；
(3) water-holding capacity of slope surface is made to improve 2 times or more.
To reach the purpose, the technical scheme is that
A kind of geotechnical grid, the geotechnical grid are made of ecological non-woven fabrics.
The raw material of the ecology non-woven fabrics uses polypropylene short fiber.
