Protective structure for disintegrated soft rock slopes in humid and hot areas

Abstract

The invention belongs to the technical field of geotechnical engineering slope protection, and provides a protective structure for disintegrated soft rock slopes in humid and hot areas. The protective structure includes: a surface drainage assembly, which includes a vegetation concrete layer covering the surface of the slope body, and a water guide member for draining surface accumulated water is arranged in the vegetation concrete layer; a middle blocking assembly, which includes an anti-seepage paving layer horizontally arranged in the middle of the slope body and a plurality of anti-seepage columns vertically and fixedly connected to the middle of the slope body, the plurality of anti-seepage columns are arranged in sequence along the transverse extension direction of the slope body and are in contact with the top surface of the anti-seepage paving layer; and a bottom reinforcement assembly, which includes a retaining wall and a drainage ditch opened at the bottom of the slope, the drainage ditch is arranged on the side of the retaining wall close to the slope body, and a drainage pipe is arranged in the drainage ditch. The present invention realizes integrated “drainage-blocking-reinforcement” protection, effectively controls the surface disintegration, internal moisture migration and bottom crack expansion, and improves the long-term stability of the slope.
