A kind of landslide strengthening method

Abstract

A landslip reinforcing method is used for reinforcing a landslip mass and includes the following steps that a plurality of reinforced concrete prefabricated triangular bodies are fixed transversely along the lower end of the surface of the landslip mass to form a first row of reinforcing structures. A second row of reinforcing structures is transversely formed on the upper end of the first row of reinforcing structures. A third row to the nth row of reinforcing structures formed by multiple reinforced concrete prefabricated triangular bodies are transversely fixed at the upper end of the second row of reinforcing structures sequentially. Passages of the first to the nth row of reinforcing structures are arranged in a staggered mode to form a bent passage net. The staggered and bent passage net is formed on the surface of the landslip mass through the reinforced concrete prefabricated triangular bodies. When a landslip happens, a surface layer ground structure or surface layer water of the landslip mass moves along the passage net, the sliding force of the landslip mass is guided and dispersed through the passage net, or the flow speed of the surface layer water is reduced, so that the purposes of avoiding or slowing down the sliding of the landslip mass and reducing landslip disasters are realized.

Description

technical field [0001] The invention relates to the field of geological landslide control, in particular to a landslide strengthening method. Background technique [0002] Landslide refers to the phenomenon that the soil or rock mass on the slope is sheared and slipped for a certain distance along a gently inclined surface under the action of gravity under the influence of factors such as river erosion, groundwater activity, rainwater soaking, earthquake and artificial slope cutting. . Landslides often cause huge losses, some even devastating disasters, to industrial and agricultural production and people's lives and property. The main harm of landslides to the countryside is to destroy farmland, houses, harm people and animals, destroy forests, roads, agricultural machinery facilities, water conservancy and hydropower facilities, etc., and sometimes even cause devastating disasters to the countryside. Landslides located in cities and towns often smash and bury houses, cas...

AI Technical Summary

Problems solved by technology

However, because the anchorage section of conventional anti-slide piles and prestressed anchor cables is too deep, the length of piles and anchor cables can range from tens of meters to nearly 100 meters, and the technical and economic rationality is poor.

For the problem of shortening the length of the anchor cable, due to the structural characteristics of the conventional anchor cable applying prestress on the slope, it is impossible to reduce the length on a large scale, which makes it difficult to apply anchoring technology, an effective means of landslide prevention and control, in deep landslide prevention and control.
