Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, and in particular relates to an ecological protection structure for a soil slope. Background Art

[0002] Exposed soil slopes are susceptible to weathering, which causes erosion of the surface soil of the slopes. Under the influence of short-term heavy rainfall, small landslides and sinkholes appear on the slope surface. Long-term weathering, erosion and scouring will lead to large-scale slope landslides, threatening the safe operation of highways. Therefore, masonry structures such as shotcrete, mortar-laid rubble and concrete are often used to protect loess slopes. Masonry protection, a "white pollution" that runs counter to the concept of green highway construction, is gradually being eliminated. Ecological protection has become the main type of soil slope protection. Common ecological protection is still combined with masonry structures, such as frame beam grass planting, hexagonal block grass planting, etc. Masonry is the basis for vegetation parasitism, and vegetation is dotted in masonry. However, slope protection methods such as grass planting, soil spraying, hydraulic spraying, and spray-mixed vegetation do not rely on masonry structures to achieve ecological slope protection, but still require the deployment of wooden boards, plugs, wire mesh and other facilities on the slope surface for preliminary treatment of the slope as the object for the sprayed soil to attach. In addition, the above-mentioned ecological protection methods are only applicable to slopes with a slope gradient of less than 1:0.75. For this reason, we propose an ecological protection structure for soil slopes. Utility Model Content

[0003] The purpose of the utility model is to provide an ecological protection structure for soil slopes to solve the problem that the slope protection methods such as grass planting, soil spraying, hydraulic spraying, and spray-mixed vegetation proposed in the above-mentioned background technology achieve ecological slope protection without the help of masonry structures, but still need to lay wooden boards, plugs, wire mesh and other facilities on the slope surface for preliminary treatment of the slope surface as the object of the sprayed soil attachment, and the above-mentioned ecological protection methods are only applicable to slopes with a slope gradient of less than 1:0.75.
