Upward-inclined type anti-sliding retaining wall for unstable slope treatment

Abstract

The invention belongs to the technical field of landslide treatment application, and particularly relates to an upward-inclined type anti-sliding retaining wall for unstable slope treatment. The upward-inclined type anti-sliding retaining wall comprises a slope and an anti-sliding retaining wall body, wherein an excavation face is arranged between the anti-sliding retaining wall body and the slope, the excavation face is obliquely arranged, a sand gravel filtering layer is arranged between the anti-sliding retaining wall body and the excavation face, the section of the sand gravel filtering layer is square, the end face of the sand gravel filtering layer and the inner side face of the anti-sliding retaining wall body are arranged in parallel, clay sealing and filling layers are arranged at the upper end and the lower end of the sand gravel filtering layer, the lower clay sealing and filling layer is arranged upwards from the ground, the upper clay sealing and filling layer is flush with the top of the anti-sliding retaining wall body, the anti-sliding retaining wall body is in an upward-inclined type, a water drainage channel is formed in the anti-sliding retaining wall body, and the water drainage channel penetrates through the anti-sliding retaining wall body. Through the design of the upward-inclined type anti-sliding retaining wall, the construction space is saved.

Description

technical field [0001] The invention belongs to the application technical field of landslide control, and in particular relates to an inclination type anti-slide retaining wall for unstable slope control. Background technique [0002] Landslide is one of the serious natural disasters. It often interrupts traffic, destroys factories and mines, blocks rivers, buries villages and towns, and causes huge losses to people's property. At the same time, it is also a kind of engineering geological disaster. Its occurrence and development are not only restricted by geological conditions and natural forces, but also significantly affected by human engineering activities. In the past half century, there have been more and more landslides in engineering activities, and the hazards have become more and more serious, which has aroused widespread concern in various countries. Therefore, the research on its occurrence, movement mechanism and prevention measures has also been unprecedentedly...

Problems solved by technology

However, because the actual operation is more complicated and the improvement effect is not easy to evaluate, it is relatively less used in the practice of landslide prevention and control engineering in my country.
