Technical Field

Background

The landslide refers to the phenomenon that soil and rock mass on a slope wholly or partially slides downwards along the slope under the action of gravity along a certain weak surface or a weak zone due to the influence of various factors. Landslide disasters are geological disasters with great harm, and the landslide development needs to be controlled and inhibited.

At present, the main structural bodies used for landslide control are: cantilever pile retaining wall, anchor pile retaining wall, gravity type retaining wall, reinforced earth retaining wall, batter pile self-balancing retaining wall and the like. Traditional retaining wall is not convenient for effectual ponding discharge with in the soil, leads to ponding softening soil to cause the landslide phenomenon, and can not effectually fix retaining wall in the basis, leads to soil to cause the phenomenon of collapsing, consequently, eliminates and alleviates water and is especially important to the harm of landslide, and its effect is: reduce pore water pressure and hydrodynamic pressure, prevent the softening and corrosion decomposition of rock-soil mass, eliminate or reduce the scouring and wave beating action of water. On the other hand, small landslides or rock and soil impact the upper part of the side surface of the retaining wall under the action of large impact inertia, so that the retaining wall is prone to toppling or the wall surface is prone to rupture, and safety is affected. In a word, the conventional soil retaining support system has a limited application range when facing complex geological conditions, and needs to solve the problems of skid resistance, load bearing, drainage, overturning, sinking, impact and the like besides landslide control, and the problems are difficult to be solved simultaneously by a single high-load anti-skid pile and a single soil retaining wall.

Therefore, in order to solve the above problems, there is a need for a novel retaining wall having an efficient drainage system, a foundation having good load-bearing, subsidence-preventing and anti-overturning capabilities, a stable structure having sufficient anti-slip capabilities, and a rock-soil impact-preventing device.
