Side slope three-dimensional ecological protection and recovery structure

Abstract

The invention discloses a three-dimensional ecological protection and restoration structure for a side slope. The three-dimensional ecological protection and restoration structure comprises an anchor net rope structure, a water delivery and supply system, a soil storage strip bag and a vegetation community, the top end of a longitudinal supporting rope of the anchor net rope structure is fixedly connected with a side slope through an anchor rod, the longitudinal supporting rope and a transverse supporting rope are combined to form a square-shaped frame, an installation net is bound and fixed to the square-shaped frame, all soil storage strip bags are fixedly connected with the installation net, vegetation communities are planted in the soil storage strip bags, and humidity probes are arranged in the soil storage strip bags. A plurality of transverse water supply and drainage pipes of the water conveying and supplying system are arranged at intervals along the slope, a longitudinal water supply pipe and a longitudinal water collecting pipe are communicated with all the transverse water supply and drainage pipes respectively, the longitudinal water supply pipe is connected with an automatic water pump water storage tank, and the longitudinal water collecting pipe is connected with a water storage tank. The automatic water pump water storage tank is provided with a rainwater sensing device, a water pump and an automatic control system, and the humidity probe is connected with the automatic control system.

Description

technical field [0001] The invention relates to the technical field of slope protection and ecological restoration, in particular to a slope three-dimensional ecological protection and restoration structure. Background technique [0002] A large number of high and steep exposed rock slopes were formed in the process of infrastructure construction, which caused damage to land resources and severely damaged the landscape. Over time, such slopes experienced geological disasters such as falling rocks, collapses, and small landslides, which seriously affected And restrict the development of ecological environment and human society. This kind of exposed high and steep slope, due to the large slope height difference, steep slope, long slope surface, poor water storage capacity, poor slope soil texture, fast and large temperature change range on the slope surface, and limited growth space for plant roots, etc. In addition, the use of concrete spray protection or the loss of nutrien...

Problems solved by technology

However, the implementation effect is not satisfactory, the cost is high, and the ecological vegetation will die in large areas after the maintenance period is over.

[0004] Existing slope ecological protection structures have higher requirements on slope ratio, and the general slope ratio requirement is not steeper than 1:0.75 (the anchor lattice is not steeper than 1:0.5), which requires excavation and repair of the slope. Large-scale soil and rock waste will be generated when repairing and repairing the slope surface, and at the same time, the wounded surface of the project will increase exponentially, causing secondary damage to the environment. In addition, in areas with low rainfall, the existing ecological protection structures of slopes cannot store water. As a result, after the maintenance period is over, a large number of vegetation on the slope surface will die due to drought, and the nutrient soil will be weathered and peeled off, resulting in the failure of the ecological restoration function.
