Water distribution, water retention and maintenance method for rock slope vegetation base material

Abstract

The invention discloses a water distribution, water retention and maintenance method for a rock slope vegetation base material. The method is characterized in that a pipeline for irrigation is buriedin the vegetation base material on a slope to realize water distribution, and water evaporation is avoided by virtue of a layer of rubble material laid on the pipeline to realize water retention and maintenance. Therefore, the irrigation pipeline is buried in the vegetation base material to achieve direct water distribution, and irrigation water is prevented from being exposed to the air to be evaporated. The layer of rubble material arranged on the pipeline can effectively break through the capillary water absorption and transpiration phenomenon of the vegetation base material in the height direction, water is prevented from being conducted from bottom to top, and therefore water evaporation can be better avoided, water retention maintenance are achieved, the irrigation effect is improved, the green plant maintenance effect is further improved, and ecological restoration of the slope is better achieved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and greening, in particular to a method for distributing water, retaining water, and maintaining a rock slope planting base material. 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....

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 am
