[0026] Example 1

[0027] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4 As shown, the present invention is an ecological restoration system for abandoned soil sites for wind farm projects, comprising a plurality of support seats 1 distributed on the slope surface, a plurality of support frames 2 distributed between two adjacent support seats 1, the support seats 1 and the support frames 2 are both fixed on the slope surface by a plurality of penetration needles 3 to achieve a preliminary positioning effect; a reinforcement net 4 is laid on a side of the support frame 2 away from the slope surface, the reinforcement net 4 is installed on the side of the support frame 2 away from the slope surface by a plurality of groups of reinforcement members 5, the reinforcement member 5 comprises a penetration portion 51 for being inserted into the slope surface and a clamping portion 52 for clamping the reinforcement net 4, and a through hole for inserting the penetration portion 51 of the reinforcement member 5 is provided on the support seat 1 and the support frame 2; after the reinforcement net 4 is laid on the support frame 2, the positioning effect of the reinforcement net 4 can be achieved by inserting a plurality of reinforcement members 5 into the slope surface. When installing the reinforcement 5, the penetration portion 51 is inserted into the through hole on the support seat 1 or the support frame 2, and then the clamping portion 52 is hammered to make the penetration portion 51 pass through the through hole and be inserted into the slope surface. While fixing the reinforcement net 4 to the support seat 1 and the support frame 2, further positioning of the support seat 1 and the support frame 2 is achieved, thereby improving the stability of the support seat 1 and the support frame 2.

[0028] Reference Figure 3 As shown, the penetration portion 51 includes a penetration anchor rod 511, and the penetration anchor rod 511 is distributed with penetration barbs 512 to improve the stability after penetration into the soil; the clamping portion 52 is a clamping plate, and the diameter of the clamping plate is larger than the diameter of the penetration anchor rod 511 to ensure that the clamping plate plays a positioning role for the reinforcement net 4 after the reinforcement net 4 is clamped on the support seat 1 or the support frame 2, so that the reinforcement net 4 is not easy to fall off the clamping plate.

[0029] Reference Figure 2 , Figure 3As shown, the support frame 2 includes two vertical sections 21 and two special-shaped sections 22 integrally formed on the brackets of the two vertical sections 21. A plug-in block 211 is provided on the side of the vertical section 21 facing the outside of the support frame 2, and a plug-in slot 11 for the plug-in block 211 is provided on the support seat 1. When installing the support frame 2, the plug-in block 211 is aligned with the plug-in slot 11 and inserted, so that the support frame 2 and the support seat 1 form a whole after being installed on the slope surface, thereby further improving stability. Multiple groups of reinforcement members 5 are provided on each special-shaped section 22, and the reinforcement members 5 can provide more support points for the reinforcement net 4 while reinforcing the special-shaped section 22, thereby improving the stability of the reinforcement net 4.

[0030] In this embodiment, the special-shaped section 22 is in an inverted V shape, so that the special-shaped section 22 has a longer length under the premise of a constant distance between the two ends, thereby improving the blocking effect on the soil and making it less likely for the soil to slide. In other embodiments, the special-shaped section 22 can also be arc-shaped or wavy, and the overall length can be increased while the positions of the two ends are fixed.

[0031] Reference Figure 1 As shown, a water storage chamber 6 is provided at one side of the bottom of the slope surface, a plurality of water leakage holes 61 are provided at the top of the water storage chamber 6, a retention mesh plate 62 is provided at one side of the water leakage holes 61, and an arc-shaped groove 7 is provided at the end of the slope surface. An inclined slope 71 is provided between the arc-shaped groove 7 and the retention mesh plate 62, and the side of the inclined slope 71 close to the retention mesh plate 62 is higher than the side of the inclined slope 71 close to the arc-shaped groove 7. When rainwater flows from the slope surface from top to bottom to the bottom of the slope, the retention mesh plate 62 can intercept the soil carried by the rainwater, thereby reducing the soil and water loss on the slope surface; the intercepted soil can flow back into the arc-shaped groove 7 under the action of the inclined slope 71, and then the staff can uniformly recover the returned soil in the arc-shaped groove 7 and re-lay it on the slope surface.

[0032] Reference Figure 1 , Figure 4 As shown, the waste soil field ecological restoration system of this embodiment also includes a water supply component 8, which includes an inlet pipe 81, a water supply pump 82, a water guide pipe 83 and an outlet pipe 84. The water supply pump 82 is arranged on the back of the slope, one end of the inlet pipe 81 is fixedly connected to the water inlet end of the water supply pump 82, and the other end extends into the water storage chamber 6, one end of the water guide pipe 83 is fixedly connected to the water outlet end of the water supply pump 82, and the other end extends to the top of the slope surface, and the outlet pipe 84 is horizontally arranged at the top of the slope surface and connected to the water guide pipe 83, and the outlet pipe 84 is distributed along its length. Multiple water outlets are distributed. When the soil water content is insufficient, the water supply pump 82 transports the rainwater collected in the water storage chamber 6 to the outlet pipe 84 through the inlet pipe 81 and the water guide pipe 83, and then sprays out from the multiple water outlets distributed on the outlet pipe 84 at the same time, that is, it can replenish water to the soil on the slope surface.

[0033] Reference Figure 4 As shown, each water outlet is connected to a water seepage component 9, which includes a main pipe 91 and a plurality of capillaries 92. The main pipe 91 is distributed along the slope surface, and the plurality of capillaries 92 are evenly distributed on the main pipe 91. The water in the main pipe 91 is evenly distributed to the slope surface through the capillaries 92 to improve the uniformity of water supply. The capillaries 92 are bent, and one end of the capillaries 92 away from the main pipe 91 is passed through the mesh of the reinforcement net 4 and attached to the slope surface. The reinforcement net 4 can play a certain fixing role on the capillaries 92, thereby improving the stability of the capillaries 92.
