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

Embodiment

[0013] Embodiment: As shown in Figure 1, this application involves three aspects of technical content, one of which is the collection of rainwater in the slope protection area of ​​the karst area. The depth is 0.5m, the length is 3-5m, and the distance between the two horizontal trenches 2 is 5-10 meters. A strip-shaped rainwater collection bag 3 is arranged in the horizontal trench. The rainwater collection bag 3 is made of thickened plastic to store rainwater. When collecting the bag, one end opening of the rainwater collection bag 3 is located in the rainwater flow and collection area on the slope, and the other end of the bag mouth is connected with the water inlet pipe of the drip irrigation 4 below its altitude, and a valve is provided on the water inlet pipe of the drip irrigation 4 to ensure that the water is fully filled. The stability of the rainwater collection bag behind the water is equipped with a support bar on the lower edge of the horizontal ditch 2, so that th...

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...
