Landslide mass reinforcing method

Abstract

The invention provides a landslide mass reinforcing method. The landslide mass reinforcing method comprises an outside intercepting ditch building step, an anti-slide pile construction step, a first pitching drainage construction step, a retaining wall construction step and a first platform intercepting ditch construction step, wherein the outside intercepting ditch building step comprises the following steps of: building an outside intercepting ditch around the periphery of a landslide mass; the anti-slide pile construction step comprises the following steps of: drilling a plurality of drill holes; placing reinforcement cages in the drill holes and pouring concrete to form anti-slide piles; sleeving cap beams at the free ends of the anti-slide piles; the first pitching drainage construction step comprises the following steps of: embedding a plurality of first drainage pipes into the landslide mass, wherein first drainage holes are formed in the peripheral walls of the first drainage pipes; the retaining wall construction step comprises the following steps of: building a retaining wall at one end, close to a road, of the landslide mass; and the first platform intercepting ditch construction step comprises the following step of: building a first platform intercepting ditch. The landslide mass reinforcing method can effectively enhance the anti-slide stability of the landslide mass, prevents the landslide mass from losing stability, avoids damage to the road, and reduces the maintenance cost of the road.

Description

technical field [0001] The invention relates to the technical field of landslide body reinforcement, in particular to a landslide body reinforcement method. Background technique [0002] At present, highway engineering is often affected by various geological hazards that affect highway driving safety, among which landslides have the greatest impact on highway driving safety. Landslides refer to the internal weakness of the rock and soil mass along the slope that constitutes the slope under the action of gravity and other external forces. There is an overall instability phenomenon. [0003] The existing common landslide reinforcement treatment methods are mainly to remove the landslide body, install anti-slide retaining piles, etc. Among them, the main form of installing anti-sliding retaining piles is rectangular anti-sliding piles, and the construction method is mainly manual digging and pouring into piles, which is relatively dangerous. The removal of landslides will inc...

Among them, the main form of installing anti-sliding retaining piles is rectangular anti-sliding piles, and the construction method is mainly manual digging and pouring into piles, which is relatively dangerous

The removal of landslides will increase the land used for road construction and increase the cost of project construction. If the treatment is not in place, it will continue to affect the safety of road use.

[0004] In addition, water is an important factor leading to the instability of landslides. Water infiltration leads to slides, increases the weight of slides, softens the soil, reduces the shear strength of soil and rock layers, and leads to landslides.

Therefore, drainage is also an important method for landslide prevention and control, while the existing anti-slide retaining piles cannot play the role of drainage
