Lateral reinforcement device for road section prone to collapse and reinforcement construction method

Abstract

The invention discloses a lateral reinforcement device for a road section prone to collapse and a reinforcement construction method. The lateral reinforcement device for the road section prone to collapse comprises a plurality of reinforcement structures and guard bars assembled between two adjacent reinforcement structures; the reinforcement structures comprise concrete pillars arranged under a road base course in a buried mode, and the concrete pillars are arranged in the transverse direction; one inner rod is fixed into each concrete pillar in a pouring mode, the left ends of the inner rodsare cut through, and the right ends of the inner rods are closed; extension rods are welded to the right end positions of the inner rods, when installation is carried out, the extension rods extend outside a mountain body; and a vertical baffle is arranged on the outer side of the road base course and abuts against the mountain body. The lateral reinforcement device aims at the road section neara cliff and reinforces a road section with loose geology, road supporting intensity is improved, and the landslide probability is reduced.

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
