Method for fixing side slope vegetation substrate capable of preventing collapse and landslide effectively

Abstract

The invention discloses a method for fixing a side slope vegetation substrate capable of preventing collapse and landslide effectively. The method is characterized in that an anchor pile is arranged on the top of a side slope as a support to provide tensile force, an anchor cable that is vertically arranged and an upper end of the anchor cable is connected with an anchor pile and a rib belt net that is arranged horizontally layer by layer and connected with the anchor cable are adopted to realize the support of the vegetation substrate, and the collapse and landslide of the vegetation substrate are prevented. With this method, the anchor rod is not needed to be arranged on the side slope for fixing, the construction difficulty and risk are greatly reduced, and the construction safety is improved. At the same time, a top anchor pile is used as the force support method to facilitate the construction of the anchor pile. At the same time, the top anchor pile can withstand a downward pulling force well and improve the fixed support effect of the vegetation substrate.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and greening, in particular to a method for fixing a slope vegetation substrate that can effectively prevent landslides from collapsing. Background technique [0002] Due to the mining of mineral resources and road construction in arid and semi-arid areas, the topography and ecological environment of a large number of closed mines and roads have been severely damaged, and many rocky slopes with large and high slopes have appeared. Usually, these high and steep rocky slopes are not covered by vegetation, have small rainfall area, and poor water holding capacity. In addition, there is little rainfall in arid areas and unstable rock masses exist on the slopes, making it extremely difficult to restore vegetation on the slopes. And it is easy to cause geological disasters such as landslides and rockfalls because the ecology cannot be restored, seriously affecting the ecological environme...

AI Technical Summary

Problems solved by technology

However, the vegetation restoration technology for high and steep rocky slopes in arid areas is still immature. Two conventional restoration technologies are used to restore vegetation on high and steep rocky slopes in arid areas, and there will be the following problems: (1) Difficult construction and high cost

Three-dimensional net spraying technology, the workload of bolting on high and steep rock slopes is heavy and dangerous, and the construction cost is high; stacking vegetation bags is dangerous when stacking vegetation bags on high, steep and unstable rock slopes High performance, heavy workload, thick planting bag, high cost

(2) Applicability is limited by the complex terrain environment

(3) There is no support for rock blocks on high and steep rock slopes

(4) It is impossible to collect and store rainwater and automatically adjust the amount of irrigation water. The single vegetation soil layer has poor water retention, so it cannot provide long-term sufficient water for vegetation on high and steep rocky slopes in arid areas. Vegetation restoration takes a long time and the effect is poor. The cost of cultivation is high

However, the following defects still exist: 1. simple anchoring cannot provide sufficient strength support effect, and deeper anchoring has defects such as difficult operation, high anchoring risk, and reduced slope stability.

2. At the same time, rainwater is directly collected for spray irrigation. The rainwater is also easy to contain dirt and cause pipe blockage. The electric control equipment for sprinkler irrigation in the field environment is restricted by power supply conditions and is prone to failure; High, and not conducive to long-term maintenance
