[0027] The technical solution of this utility model will be further described below with reference to specific embodiments:
[0028] An eco-friendly slope protection system that harvests rainwater, such as Figure 1 As shown, it includes a planting bag layer 2, an inclined slope 3, a bottom design ground layer 4, and a flood interception dry stream 5, all arranged sloping downwards along the top design ground layer 1; the angle of the inclined slope is less than 90 degrees. The top design ground layer 1 and the bottom design ground layer 4 are gentle lawn planting areas, usually designed to be horizontal or nearly horizontal.
[0029] The vegetation bag layer 2 includes several vegetation bags stacked along the edge of the top layer 1. The inclined slope 3 is anchored with a metal mesh 6. The surface of the metal mesh 6 is sprayed with a planting base layer, such as soil culture medium, and the spraying is carried out by high-order granular spraying technology.
[0030] The flood-intercepting dry stream 5 is recessed relative to the bottom design ground layer 4. From top to bottom, the flood-intercepting dry stream consists of a water storage layer 7, a clay protective layer 8, a non-woven fabric layer 9, a bentonite waterproof blanket layer 10, a sand layer 11, and a plain soil layer 12. Vegetation bags 13 are laid sloping upwards from the clay protective layer 8 along the slopes on both sides of the flood-intercepting dry stream. Figure 2 As shown, the subgrade layer 12 and the clay protective layer 8 should be compacted. More specifically, the compaction degree of the clay protective layer should be ≥85%, the non-woven fabric layer should be made of 200g / ㎡ non-woven fabric, the bentonite waterproof blanket should be made of 5kg / ㎡ waterproof blanket, and the thickness of the sand layer should be 300mm.
[0031] Among them, the metal mesh, such as galvanized welded wire mesh, has a mesh size of 50mm*50mm. The metal mesh is anchored by anchor rods. When anchoring, anchor holes need to be drilled at the center of the mesh on the sloping surface, and the anchor rods are finally fixed in the anchor holes.
[0032] In this embodiment, the anchor bolt is as follows: Figure 3 As shown, the anchor bolt includes a screw 14, a clamp 15, a sleeve 16, an expansion sleeve 17, and a frustum-shaped protrusion 18. A circular hole for the screw 14 to pass through is provided in the center of the clamp 15, and a hook 19 is provided on each of the four sides of the clamp 15. Several slots 20 are provided on the side wall of one end of the expansion sleeve 17. The screw 14 passes sequentially through the circular hole in the center of the clamp 15, the sleeve 16, and the expansion sleeve 17, and then engages with the central thread of the protrusion 18. The smaller end of the protrusion 18 is inserted into the end of the expansion sleeve 17 with the slot 20. In use, the anchor bolt is arranged according to… Figure 3 To assemble, tighten screw 14 to pre-tighten clamp 15, sleeve 16, expansion sleeve 17, and protrusion 18. Insert anchor rod into anchor hole and adjust the direction of four hooks so that each hook engages with one of the four nodes of metal mesh.
