Problems solved by technology
[0004] The present invention aims at the irrigation dependence problem existing in the existing ecological slope protection, and provides an ecological slope protection device for slopes in semi-arid areas to solve the problem of slope protection in slopes with thin soil covering layers or semi-arid areas
The ecological slope protection device not only solves the problem of vegetation water supply but also helps to reduce the problem of precipitation scouring the slope surface, effectively improving the slope protection effect

Embodiment 1
[0022] The specific implementation process of this embodiment includes the following steps:
[0023] (1) Excavate the slope water guide trench 2 at the position where the slope 1 needs greening, excavate a plurality of wells in the slope surface water guide trench 2, and bury the water storage pipe 6 in the pit well; The trenches 2 are generally arranged along the terrain contour on the plane, and the distance between the water guide trenches 2 on the slope surface is 10-15m; For drilling with drilling rigs, downward inclined holes are generally used to reduce the height difference between the bottom of the hole and the opening of the hole; the depth of the manual digging hole is 1-2m, the diameter is 0.3-0.5m, and the spacing is 5-10m. The hole depth is 3-4m, the diameter is 0.1-0.3m, and the spacing is 3-6m.
[0024] (2) Put the water storage pipe 6 in the excavated well, the water storage pipe 6 adopts a PVC pipe with one end sealed and one end open, the size of the PVC pi...

The invention discloses an ecological slope protection device for slopes in a semi-arid area. Rainy season precipitation is collected and stored in a water storage pipe below the slope surface, and water in the water storage pipe is slowly released to a slope soil layer in a capillary way in a dry season and is used for solving the problem of water supply of a thin slope soil covering layer or side slope protection vegetation in the semi-arid area. The device is composed of a water collection system, a water storage system and a water supply system, wherein the water collection system comprises a slope water guide trench and a water guide body; the water storage system comprises a water storage pipe, a filter layer and a cover plate; the water supply system is composed of a capillary tube; one end of the capillary tube stretches into the bottom of the water storage pipe, and the other end of the capillary tube is positioned in a soil layer needing to be wetted. By utilizing the capillary action, water stored in the water storage pipe is slowly conveyed into the side slope soil layer so as to avoid vegetation dying, and therefore, the vegetation achieves the aims of achieving slope anchoring with taproot and shallow root reinforcing effects, reducing slope pore water pressure, controlling water and soil loss, intercepting rainfall, weakening the influence of splash erosion on slope stability, and the like.
Description
technical field [0001] The invention belongs to the field of environmental geotechnical engineering, and in particular relates to a slope protection device for supplying water to slope vegetation in a slope with a thin soil covering layer or in a semi-arid region. Background technique [0002] In the field of slope protection, planting vegetation on the slope for ecological slope protection is not only environmentally friendly, but also low in cost. The use of slope vegetation for ecological slope protection mainly uses the deep root anchoring effect of vegetation, shallow root reinforcement, reducing slope pore water pressure, and controlling Soil erosion, rainfall interception and weakening impact of splash erosion on slope stability, etc. However, because the terrain of the slope is not conducive to the stagnation of rainwater, especially in the slopes with thin cover layers or semi-arid areas, although the rainfall supply in the rainy season can meet the growth needs of ...
