Reinforcement and emergency construction method after soil slope landslide collapse

Abstract

Provided is a reinforcement and rescuing construction method used after landslide and collapse of a soil slope. Firstly, steel bars are inserted at the positions of landslide and collapse of a soil slope; secondly, grouting holes are drilled in soft soil; thirdly, grouting materials are prepared for use; fourthly, the inserted steel bars are transversely bundled into a whole through steel wires, or the inserted steel bars are welded into a whole in an electric welding mode; fifthly, the sunken portion of the collapse is filled with plant fibers and leveled; finally, the prepared grouting materials are injected into the grouting holes and the place filled with the plant fibers at high pressure through a grout injecting machine, and after the grouting materials are solidified, a fixed whole of the soil slope can be formed after landslide and collapse. According to the method, landslide soil does not need to be wiped out; the soft soil is changed into a tight rock-similar body through the grout injecting technology, and the plant fibers and the grouting materials form the stable and tensile concrete whole. Materials can be obtained conveniently; the mechanization degree of construction is high, construction speed is high, and the reinforcing effect is good. The method is suitable for reinforcement and recuing after landslide and collapse of soil slopes around mountainous area highways, railways, bridges and building structures.

Description

technical field [0001] The present invention relates to the protection of surrounding soil of buildings, and further relates to the protection of surrounding soil slopes of roads, railways or bridges, especially the reinforcement and emergency construction of soil slopes after landslides collapse. Background technique [0002] As we all know, landslides and landslides are very common in the surrounding areas of roads, railways, bridges and even mountain slopes, especially in the rainy season. Once a landslide occurs, it will not only block traffic, but also endanger people's lives. In order to reduce the resulting losses, timely rescue and disaster relief are required after the landslide collapses. However, due to the soft soil of the slope, it is not easy to rescue the landslide after the collapse, and the cost of rescue construction is also quite high. The commonly used emergency construction method is to remove part of the landslide earth and rocks and then fill them wi...
