Gabion bracing system for ecological restoration of high-steep rock slope and laying method of gabion bracing system

Abstract

The invention relates to a gabion bracing system for ecological restoration of a high-steep rock slope and a laying method of the gabion bracing system. The structure of the gabion bracing system is formed through the combination of hexahedrons which are composed of gabion pieces and internally provided with planting chambers, wherein the front side face, the rear side face, the left side face, the right side face and a middle partition plate are each of a hollow structure and are each composed of two layers of metal mesh surfaces, wherein the distance between the two layers of metal mesh surfaces is equal to the size of a mesh, and each planting chamber is formed between the two corresponding layers of metal mesh surfaces. Gabion boxes are staggered and laid from the bottom of the slope to the top of the slope in sequence, and the staggered distance is equal to 1/2 of the length of a gabion box. In the laying process, the bottoms of the gabion boxes are connected by using shooting wires, and the tops of the gabion boxes are connected by using shooting wires. At the toe of the slope, slope toe pressing is conducted by using a reinforced concrete retaining wall, and the stability ofa gabion bracing structure is improved. The Gabion boxes are filled with filler prepared from slope cutting broken stone, the ecological environment of the slope can be restored as soon as possible,and the local slope cutting broken stone substances can be further utilized to the greatest extent. The gabion bracing system is suitable for slope surface protection of the overall stable rock slopewith the height smaller than or equal to 10 m and the gradient smaller than or equal to 45 degrees.

Description

technical field [0001] The invention relates to a support structure and a laying method for improving the stability and ecological protection of mountain cutting slopes. Background technique [0002] In engineering construction in mountainous areas, it is often necessary to cut the slope of the mountain to improve the use function. For example, mountain slope cutting in road construction, alpine slope cutting in winter Olympic ski resort construction, etc. On the one hand, slope cutting leads to changes in the stress state of the mountain, which in turn leads to a change in the stable state of the slope, and even causes geological disasters such as landslides, landslides, and debris flows; on the other hand, slope cutting also causes damage to the ecological environment of the mountain. , lead to soil erosion, but also destroy the ecosystem, the living environment of animals and plants is seriously disturbed and other hazards. Furthermore, the removal of the cut rock block...

Problems solved by technology

On the one hand, slope cutting leads to changes in the stress state of the mountain, which in turn leads to a change in the stable state of the slope, and even causes geological disasters such as landslides, landslides, and debris flows; on the other hand, slope cutting also causes damage to the ecological environment of the mountain. , lead to soil erosion, but also destroy the ecosystem, the living environment of animals and plants is seriously disturbed and other hazards

Furthermore, the transportation of the cut rock blocks not only increases the construction cost, but also the landfill of the rock blocks has a significant negative impact on the environment of the landfill.
