A lateral reinforcement device and reinforcement construction method for a subsidence-prone road section

Abstract

The invention discloses a lateral reinforcement device and a reinforcement construction method for an easily-collapsed road section, which comprises a plurality of reinforcement structures and guard rails assembled between two adjacent reinforcement structures; the reinforcement structure includes a Concrete column, the concrete column is arranged horizontally, and an inner rod is poured and fixed inside the concrete column, the left end of the inner rod is penetrated, and the right end is closed, and an extension rod is welded at the right end of the inner rod. At the same time, the extension rod extends to the outside of the mountain, and a vertical baffle is arranged on the outside of the road base, close to the mountain; the present invention is aimed at the cliff-side road section, and the road section with soft geology is reinforced to increase the support strength of the road surface and reduce the probability of landslides .

Description

technical field [0001] The invention relates to a lateral reinforcement device and a reinforcement construction method for a road section prone to collapse. Background technique [0002] In some areas with heavy rainfall, the mountain roads in mountainous areas are very prone to collapse due to the erosion of rainwater. The reason is that the rock layer below the road surface as the roadbed is relatively loose, which is crushed by vehicles and combined with the erosion of rainwater. Leading to the failure of the support, leading to the local collapse of the road surface, there is a big safety hazard. [0003] The existing reinforcement methods are mainly to build steel wire mesh on the outside of the roadbed to reduce water and soil loss through the steel mesh, thereby reducing the probability of road surface collapse. However, in practical applications, the laying of steel mesh does not play any role in supporting the road surface. It can only passively reduce the loss of ...

[0002] In some areas with heavy rainfall, the mountain roads in mountainous areas are very prone to collapse due to the erosion of rainwater. The reason is that the rock layer below the road surface as the roadbed is relatively loose, which is crushed by vehicles and combined with the erosion of rainwater. Leading to the failure of the support, leading to the local collapse of the road surface, there is a big safety hazard

[0003] The existing reinforcement methods are mainly to build steel wire mesh on the outside of the roadbed to reduce water and soil loss through the steel mesh, thereby reducing the probability of road surface collapse. However, in practical applications, the laying of steel mesh does not play any role in supporting the road surface. It can only passively reduce the loss of soil and stones, but in the case of soft roadbed, if a local collapse occurs on the outside of the road surface, the protection of the steel mesh is insufficient to provide effective support, causing the vehicle to roll over into the cliff
