Slope vegetation restoration system construction method

Abstract

The invention discloses a slope vegetation restoration system construction method. The method comprises a step of laying a rainwater collection and storage unit at the top of a slope, and a step of arranging a vegetation base material and an irrigation pipe network on the slope, and is characterized in that an anchoring system for fixing the vegetation base material is firstly arranged before thevegetation base material is arranged, then the vegetation base material is arranged, when the vegetation base material is arranged, a water-holding alien soil layer is laid on the bottom surface of the slope firstly, then a vegetation layer containing plant seeds and a water-retaining layer above the vegetation layer are arranged, the vegetation layer is obtained by laying prefabricated vegetationlayer building blocks, and the water-retaining layer is obtained by laying prefabricated water-retaining layer building blocks. In this way, during construction, in the vegetation base material, thewater-holding alien soil layer can be firmly attached to the slope surface through on-site construction. The vegetation layer and the water-retaining layer are produced in a factory standardized modeto form a building block structure, and only the vegetation layer and the water-retaining layer need to be simply piled and fixed to the water-holding alien soil layer during construction. Therefore,the construction efficiency can be greatly improved through the combination of the vegetation layer and the water-retaining layer.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and greening, in particular to a construction method for a slope vegetation restoration system. 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 environment. Therefore, it is urgent to revegetat...

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
