Rock slope ecological restoration system

Abstract

The invention discloses a rock slope ecological restoration system. The system comprises a rainwater collection and storage unit arranged at the top of a slope, plant growing media fixedly laid on theslope, an anchoring system used for fixing the plant growing media and an irrigation pipe network buried in the plant growing media; and a water inlet end of the irrigation pipe network is connectedwith the rainwater collection and storage unit. The system is characterized in that the rainwater collection and storage unit comprises a water collecting tank which is arranged at the top of the slope and adjacent to the slope; a filtering structure is arranged in the water collecting tank; the edge of the water collecting tank is connected with a water storage chamber; the water storage chambercan be immersed in water in the water collecting tank; and the water storage chamber is connected with the water inlet end of the irrigation pipe network. The rock slope ecological restoration systemhas the advantages rainwater can be better collected for regular irrigation, the dependence of irrigation control on electric equipment is reduced, the slope greening ecological restoration effect isimproved, and the construction safety and economy are improved. The system is especially suitable for vegetation restoration and greening of high and steep rock slopes in arid regions.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and greening, in particular to a rock slope ecological 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 revegetate the artificial high...

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
