Embodiment
[0032] as attached figure 2 As shown, taking Wulingyuan (Mausoleum) in Xianyang City as an example, the described slope protection structure for water and soil erosion includes slope protection body, rainwater filtering device, intercepting ditch, drainage ditch, water storage tank, ecological gabion and retaining wall;
[0033]The slope protection body is inclined on the four slopes of Wulingyuan (mausoleum), and several steps are arranged on the slope protection body, and a triangular groove belt is arranged in each step, and a rainwater filtering device is arranged in the triangle groove belt; The filter device consists of two perforated steel plates, multi-level covering layers and drainage channels. The two perforated steel plates are respectively placed on both sides of the triangular groove belt. Between the perforated steel plates, the drainage channel is arranged under the multi-level covering layer, and the drainage channel is connected with the slope drainage syst...

The invention discloses a slope protection structure being answerable for water and soil loss. The slope protection structure comprises a slope protection body, wherein a plurality of stages of stepsare arranged on the slope protection body, a triangular groove belt is arranged in each step, a rainwater filtering device is arranged in each triangular groove belt, each rainwater filtering device comprises two punching plates, a multi-stage covering layer and a drainage channel, wherein the two punching plates are tightly attached to the two sides of the triangular groove belt correspondingly,the multi-stage covering layer is arranged between the two punching plates at one time from top to bottom, the drainage channel is arranged below the multi-stage covering layer, and the drainage channel communicates with a slope surface drainage system. According to the slope protection structure, the rainwater filtering device is arranged on each stage of the step, and stepped interception of precipitation is achieved; when the precipitation amount is small, precipitation can be naturally permeated into the slope surface soil through the punching plates; when the precipitation amount is large, a small amount of precipitation directly penetrates into the slope surface soil, and the remaining precipitation is gathered to the slope surface drainage system through the drainage channels to bedrained; and precipitation is prevented from directly flushing the slope surface, and the water and soil loss of the slope surface is reduced.
Description
technical field [0001] The invention belongs to the technical field of ecological protection, in particular to a slope protection structure for dealing with soil erosion. Background technique [0002] In some topographical slopes, due to the scarcity of plants and low coverage, water and soil erosion occurs all year round on gentle slopes; it has caused certain damage to the surrounding ecology and soil structure. For gentle slopes with loose soil, when the dry season comes, the surface is exposed and the water evaporates a lot; in the rainy season, the rainwater directly scours the slope surface, resulting in soil erosion, and in severe cases, landslides occur. The sliding force of the soil increases, and vegetation cannot grow. A vicious cycle of regional ecology is formed; most of the existing slope protection structures have a large proportion of hard areas, and the soil cover is thin, which is not conducive to the growth of plants and the creation of biological habitats...
