Description

Technical Field

[0001] The invention relates to the technical field of stone slope restoration, and in particular to a soil and water conservation device for ecological restoration of stone slopes. Background Art

[0002] Some high and steep stone slopes or rock dump slopes, due to their high and steep slope instability and poor safety factor, often need to be cut and lowered to reduce the slope of the stone slope to below 35 degrees, and then covered with soil for repair or spray repair, etc. However, since the slope is a giant artificial loose accumulation of loose waste rock, when the root system of the repaired plants is not well developed, the slope fixation strength is insufficient. When encountering stormy weather, due to the poor stability of the slope of waste rock accumulation, it is very easy to cause landslides, mudslides and other geological disasters under the continuous infiltration of rainwater. In addition, since the slope below the covering soil or spraying matrix is ​​composed of waste rock accumulation, the water retention performance is extremely poor, a large amount of water is required for later maintenance, and its internal structure is not stable.

[0003] According to patent number CN217974432U, a utility model patent for a stone slope microecological restoration device includes a slope body, a concrete layer is arranged on the surface of the slope body, a steel wire mesh is installed on the top of the concrete layer, a soil layer is laid on the surface of the steel wire mesh, and a plurality of guardrails are installed on the top of the soil layer. The beneficial effects of the utility model are as follows: the stone slope microecological restoration device, through the overall stepped structure of the slope, cooperates with the concrete layers and soil layers superimposed on the slope in sequence, strengthens the rock waterproofing measures in the slope, promotes the growth and development of plants, intercepts rainwater, reduces runoff, and increases soil moisture, and guardrails are installed on the edge of the trapezoid, and the protective frame at the bottom can be used to protect the soil to prevent soil erosion caused by rainwater scouring, and the slope protection net at the top can drain excess rainwater to avoid excessive moisture remaining in the soil, causing root rot and the like.

[0004] Although the above technical solution can achieve the repair of stone slopes and soil and water conservation, and its stepped concrete surface can prevent rainwater from penetrating into the rock and reduce the strength of the rock or soil, it does not reinforce the interior of the slope and still has the risk of landslide. In addition, the design of the guardrail is not only complicated to operate but can only maintain the soil and water on the horizontal slope state. It is difficult to ensure the stability of the soil and water on the slope, and has certain limitations in actual use. Summary of the invention

[0005] The purpose of the present invention is to provide a soil and water conservation device for ecological restoration of stone slopes, which can not only reinforce the interior of the stone slope, improve the stability of its stone pestle and reduce the risk of landslides, but also reduce the probability of soil and water loss on the slope in the later ecological restoration, so as to achieve the effect of soil and water conservation.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:
