AI Technical Summary

Technical Problem

The existing expansive soil slope protection device does not have a support structure, and the expansive soil absorbs water and causes landslides, making it impossible to effectively protect the slope.

Method used

An expanded soil slope protection device is designed including a baffle, a support assembly, a stabilization assembly, a pressure assembly, a tension assembly and a pull-down assembly. By laying geotextiles on the surface of the expanded soil, the stabilizing frame is in contact with the geotextile, and the steel wire rope and tensioning assembly are used to apply pressure to the stabilizing frame to prevent landslides.

Benefits of technology

It effectively avoids the landslide phenomenon after the expansion of expansive soil absorbs water, realizes stable protection of the slope of expansive soil, and reduces the contact time between water and expansive soil.

Abstract

The present invention belongs to the technical field of expansive soil slope protection, and discloses an expansive soil slope protection device, including a baffle plate arranged at the bottom corner of the expansive soil slope, and also including: a support assembly, wherein the support assembly is arranged at the top of the expansive soil. The present invention lays a geotextile on the surface of the expansive soil, places the baffle plate at the bottom corner of the expansive soil slope, installs the support assembly on the top of the expansive soil, places a stabilizing frame on the expansive soil slope and contacts the geotextile, passes a steel wire rope through a butt joint pipe and a pull-down assembly in sequence, and connects the other end to a tensioning assembly. Since the toothed rod is engaged with the tensioning assembly, the steel wire rope is tightened by rotating the tensioning assembly, and an angle is formed when the steel wire rope passes through the butt joint pipe, so that a downward thrust is applied to the stabilizing frame by tightening the steel wire rope, and the effect of slope protection is achieved by the pressure applied to the expansive soil by the stabilizing frame and the geotextile, and the phenomenon of landslide caused by water absorption and swelling of the expansive soil is effectively avoided.
