Novel retaining wall for inhibiting development of landslide and construction method

Abstract

The invention relates to a novel retaining wall for inhibiting the development of a landslide and a construction method, and belongs to the field of landslide geological disaster prevention and control. A composite foundation is designed, the lower end surface of the composite foundation is in a stepped shape, and the composite foundation is paved under the water seepage retaining wall; a wall body of the water seepage retaining wall is hollow, and one side of the wall body is provided with a water seepage gap; anchoring is reinforced, anchors are connected with the water seepage retaining wall, wherein each automatic anchor is provided with an automatic installation system consisting of a PID controller, a frequency converter, an electric control valve and the like, and a threaded anchorpile pulling device can provide strong overturning resistance torque for the retaining wall; a rock-soil collision prevention device is provided with a two-stage buffer structure and is arranged on the top of the water seepage retaining wall; a high-load slide-resistant pile is provided with a load plate and a bottom block and is fixed on one side of the composite foundation; and a drainage systemis provided with a rainwater intercepting and discharging device and a water collecting pipeline so as to reduce the water content of a landslide body and slow down the development of the landslide body. The retaining wall has a plurality of functions of overturning prevention, subsidence prevention, rock-soil collision prevention, rainwater interception and drainage, landslide development inhibition and the like.

Description

technical field [0001] The invention relates to a novel retaining wall and a construction method for inhibiting the development of landslides, which belong to the field of prevention and control of landslide geological disasters. Background technique [0002] Landslide refers to the phenomenon that the soil and rock mass on the slope slides down the slope in whole or in part along a certain weak surface or belt under the action of gravity due to the influence of various factors. Landslide hazards are geological disasters with great hazards, and the development of landslides needs to be controlled and restrained. [0003] At present, the structures used for landslide control mainly include: cantilever pile retaining wall, anchor pile retaining wall, gravity retaining wall, reinforced soil retaining wall, inclined pile self-balancing retaining wall, etc. The traditional retaining wall is not convenient to effectively discharge the accumulated water in the soil, causing the ac...

AI Technical Summary

Problems solved by technology

The traditional retaining wall is not convenient to effectively discharge the accumulated water in the soil, causing the accumulated water to soften the soil and cause landslides, and it cannot effectively fix the retaining wall in the foundation, causing the soil to collapse. Therefore, to eliminate and alleviate The harm of water to landslides is especially important. Its role is to reduce pore water pressure and dynamic water pressure, prevent softening and dissolution of rock and soil, and eliminate or reduce water erosion and wave impact.

On the other hand, small landslides or rocks and soils impact the upper side of the retaining wall under the action of large impact inertia, which may easily cause the retaining wall to fall or the wall surface to crack, affecting safety.

In short, the traditional retaining support system has a limited application range when faced with complex geological conditions. In addition to landslide control, it also needs to solve problems such as anti-slide, load-bearing, drainage, overturning, subsidence and impact. Single high-load anti-slide piles, retaining Earth walls are difficult to solve the above problems at the same time
