Abstract

The invention provides a rock-soil body side slope corrosion resistance and ecological restoration protection method which is used for solving the problem of water and soil losses caused by rain wash on a side slope soil body and achieving the aim of ecological restoration of an exposed side slope of a rock body. The rock-soil body side slope corrosion resistance and ecological restoration protection method is characterized in that an ecological stabilizer is adopted, the stabilizer is prepared by anionic polyacrylamide, potassium chloride, ethyl acrylic ester, epoxy acrylic ester and water according to the proportion, the blending mass ratio under the condition of the room temperature is 0.5: 2: 0.5: 0.5: 96.5 in sequence, and after engineering protection on the side slope is finished, the stabilizer is adopted for ecological greening and corrosion resistance protection. A pump-type wet spraying machine is adopted to pump the mixture soil of the stabilizer, soil, grass seeds and shrubs to the surface of the side slope, construction is carried out from left to right and from top to bottom, the mixture soil can be sprayed 1-3 times in a layered mode, the thickness of the mixture soil on the surface of the side slope of the soil body reaches 5-10cm, and the thickness of the mixture soil on the surface of the side slope of the rock body reaches 10-15cm; non-woven fabric is adopted to cover the mixture soil on the surface of the side slope, drop irrigation is carried out, grass is trimmed regularly after growing up, and growth of the shrubs is promoted.

Description

technical field [0001] The invention relates to a slope ecological restoration and protection method, which belongs to the technical field of civil (rock and soil) engineering. Background technique [0002] For the special rock and soil in Southwest China, such as the sandy soil formed by fully weathered granite gneiss, the particles are fine, the particles are loose and have no cohesion, and it is easy to be washed and lost when softened and expanded by water; expansive soil and laterite areas Disaster problems such as water swelling and dehydration shrinkage often occur. At present, there are no effective and practical countermeasures for the loss of sandy soil, disaster prevention and control of expansive soil, and ecological restoration of exposed rock slopes. Anchor (cable) sash beam protection or arched slope protection and other engineering protection measures, and then greening measures such as planting bags or guest soil spraying, to ensure the stability and aesthe...
