A kind of protecting slope ecology structure, comprise protecting film, described side slope is provided with about 10-30cm of a plurality of degree of depth and vertical domatic groove, and described adjacent trenches spacing is 30-60cm, one side of described protecting film is imbedded in the described groove, and opposite side covers on the described side slope between the described adjacent trenches.
In the utility model, described protecting film is geotextiles or plastic foil body.
In the utility model, the fabric width of described geotextiles or plastic foil body is 30-70cm.
In the utility model, the part that does not cover described protecting film on the described side slope between the adjacent described groove is provided with concave panel, and the part that covers described protecting film on the described side slope is provided with convex, and described concave panel and described convex form the erosion control brush layer.
In the utility model, described protecting film covers and unlapped described side slope is provided with slope vegetation.
As another kind of mode of the present utility model, a side of described protecting film is imbedded in the described groove, and opposite side is imbedded in the described adjacent trenches.
Adopt such scheme, after protecting film of the present utility model is laid on the side slope surface, form the wall body structure that anti-current wash away owing to imbed the protecting film that groove is fixed in the soil, the convex surface that covers the protecting film on side slope surface and its side slope soil formation down has the effect of anti-surface erosion again, with the domatic common formation protection against erosion structure of the spill in its downstream, its effect is similar to the protection against erosion structure of concrete hollow block, therefore when rainwater forms slope runoff, the domatic soil of rain drop erosion can be avoided or reduce to protecting film convex covering layer and the buried erosion control protection against erosion structure that mutual group becomes of whitewashing a wall, play solid soil and fix the sand the effect of protection against erosion, stable after keeping slope construction to finish.Above-mentioned protecting film body cover and unlapped domatic soil in other plants such as grass planting or plantation shrub of can sowing grass seeds by duster, the protecting film covering layer does not influence the greening vegetation on side slope surface.
