Rainwater collection and irrigation integrated karst region slope protection method and structure

Abstract

The invention discloses a rainwater collection and irrigation integrated karst region slope protection method and structure. The method includes: arranging horizontal ditches in the slope surface needing to be cared in a karst region at intervals, and placing a strip-shaped rainwater collection bag in each ditch, wherein a bag opening at one end of each rainwater collection bag is arranged in a slope surface rainwater flowing and gathering area, and a bag opening at the other end of each rainwater collection bag is connected with a drip irrigation water inflowing pipe lower than the altitude thereof; arranging vegetation devices in a drip irrigation arranging area, spraying and seeding artificial soil containing seeds on the vegetation devices or packing a vegetation bag in each vegetation device, wherein each vegetation bag is filled with soil and seeds. Therefore, in seasons with less rainfall, control valves can be turned on to supplement water to the whole slope surface needing to be cared by drip irrigation, and moisture needed for growth is guaranteed.

Description

technical field [0001] The invention relates to a method and structure for slope protection in karst areas integrated with rainwater collection and irrigation, and belongs to the technical field of slope care in karst areas. Background technique [0002] Karst landform refers to various landforms formed by the dissolution of soluble rocks by water and the accompanying mechanical action. Karst landforms are widely distributed in Guangxi, Guizhou, Yunnan and other places in China. In recent years, with large-scale engineering construction and mining, a large number of exposed slopes have been formed in karst landforms, resulting in a large number of rock and soil slopes that cannot recover vegetation. It is almost impossible to restore natural vegetation coverage on the surface in a short period of time. . Existing reinforcement measures for slope engineering mostly pursue strength and efficiency, and most of them use gray protection such as stone masonry and shotcrete, whic...

AI Technical Summary

Problems solved by technology

The effect of the above-mentioned patent applicant is very remarkable in the process of use, but the applicant found that due to the influence of the environment and geology, the slope of the slope in the karst area cannot store water well. Death due to lack of water, the current method is to use the spray gun of the high-pressure water truck to spray water on the slope. The method has the following problems. The water sprayed by the first high-pressure water gun is easy to wash away the solid soil layer formed on the slope; Second, artificial water spraying cannot achieve uniform watering; third, the cost of water transportation and high-pressure water spray vehicles is relatively high, and in seasons of water shortage, the amount of water volatilized by water spraying is relatively large, and the effective utilization rate is low; Four cannot be popularized on a large scale
