Automatic water supply irrigation method for controlling slope green plants

Abstract

The invention discloses an automatic water supply irrigation method for controlling slope green plants. The method is characterized in that stored irrigation water is injected into a water control tank which is rotatably arranged at a stable flow rate, so that when the amount of the stored water in the water control tank exceeds a set water amount, the gravity center of the water control tank is shifted and the water control tank is overturned and toppled, and the water stored in the water control tank is poured into an irrigation pipe network to realize single water supply; and after the stored water in the water control tank is poured into the irrigation pipe network, the gravity center position of the empty water control tank is restored and overturned to be reset, and the next water injection is continued and circulated, so that intermittent continuous water supply irrigation of the irrigation pipe network is realized. The method can realize mechanical automatic water supply irrigation of the irrigation pipe network at regular time and quantity. The dependence of the irrigation control process on electric power is reduced, so that the method is more suitable for being used in afield slope greening ecological restoration system.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and greening, in particular to a method for controlling automatic water supply to green plants on a slope. 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 t...

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
