[0005] Preferably, straw layers and fine sand layers are provided in the water storage and moisturizing box, and the straw layers and fine sand layers are arranged alternately.

[0006] A method for repairing a mine slope ecological restoration structure is performed according to the following steps: s1. Clean the mine slope, remove loose soil and gravel, and divide the slope into multiple areas from top to bottom; s2. Excavate transverse trenches at the bottom of each subdivided area. The transverse trenches are excavated horizontally along the slope with a depth of not less than 1m. At the same time, longitudinal trenches are excavated longitudinally along the slope within the area with a depth of not less than 0.5m. The longitudinal trenches are connected to the transverse trenches. s3. Place the water storage and moisturizing box in the horizontal groove, the water storage pipe in the longitudinal groove, and connect the water outlet of the water storage pipe to the water storage and moisturizing box. Lay a layer of straw in the water storage and moisturizing box, then lay a layer of fine sand, and then lay a layer of straw and fine sand on one side, and repeat this process until the box is full. The thickness of the fine sand and straw should not be less than 20 cm. s4.

The planting matrix soil covers the entire slope with a spraying thickness of 10-15cm to complete the repair of the mine slope.

[0007] Compared with the existing technology, the present invention has the following technical effects: the present invention reconstructs the water circulation of the mine slope through a water storage and moisturizing box, a water-absorbing fiber cloth and a water storage pipe, uses the water storage and moisturizing box and the water storage pipe to recycle rainwater, and then circulates it to the crop growth soil layer through the dilution fiber cloth, providing a good growth environment for crops, ensuring that crops have sufficient rainwater, and thereby improving the survival rate of crops. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0009] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0010] like Figure 1 As shown, a mine slope ecological restoration structure includes a plurality of pits 1 arranged on the mine slope and a plurality of water pipes 2 laid along the slope, a plurality of water permeable holes are provided on the pipe wall of the water pipe 2, a water storage and moisturizing box 3 is installed in the pit 1, one end of the water pipe 1 located at the low point is connected with the water storage and moisturizing box 3, a first planting soil layer 4 is laid on the water storage pipe 1, a water-absorbing fiber cloth layer 5 is laid on the first planting soil layer 4, the lower part of the water-absorbing fiber cloth layer 5 is buried in the water storage and moisturizing box 3, a metal wire mesh 6 is laid on the water-absorbing fiber cloth layer 5, the metal wire mesh 6 is fixed to the slope by anchor nails 7, a second planting soil layer 8 is laid on the metal wire mesh 6, and a planting matrix layer 9 is provided on the second planting soil layer 8.

[0011] The present invention adopts a water storage and moisturizing box 3 with a water storage and moisturizing function. A straw layer 10 and a fine sand layer 11 are provided in the water storage and moisturizing box 3. The straw layer 10 and the fine sand layer 11 are arranged alternately, and water retention and moisturizing are achieved by the straw layer 10 and the fine sand layer 11. The water storage pipe 1 can collect rainwater from the slope. After the rainwater seeps into the soil, it enters the water storage pipe 1 through the water permeable hole and then flows into the water storage and moisturizing box 3 for storage. One end of the water-absorbing fiber cloth layer 5 is buried in the water storage and moisturizing box 3. The water absorption performance of the water-absorbing fiber cloth layer 5 is utilized to absorb water into the soil layer of the crop, providing moisture for the crop. The wire mesh 6 can reinforce the soil on the slope, prevent water and soil instability, and affect the stability of the soil.

[0012] When using it, please follow the steps below: s1. Clean the mine slope, remove loose soil and gravel, and divide the slope into multiple areas from top to bottom; s2. Excavate transverse trenches at the bottom of each subdivided area. The transverse trenches are excavated horizontally along the slope with a depth of not less than 1m. At the same time, longitudinal trenches are excavated longitudinally along the slope within the area with a depth of not less than 0.5m. The longitudinal trenches are connected to the transverse trenches. s3. Place the water storage and moisturizing box in the horizontal groove, the water storage pipe in the longitudinal groove, and connect the water outlet of the water storage pipe to the water storage and moisturizing box. Lay a layer of straw in the water storage and moisturizing box, then lay a layer of fine sand, and then lay a layer of straw and fine sand on one side, and repeat this process until the box is full. The thickness of the fine sand and straw should not be less than 20 cm. s4. Lay a layer of planting soil on the water storage pipe with a thickness of 15-20cm, then lay absorbent fiber cloth and wire mesh on the planting soil. At the same time, use anchor nails to fix the wire mesh and absorbent fiber cloth on the slope. The wire mesh is required to cover the entire slope. s5. Spray planting matrix soil on the wire mesh. The planting matrix soil covers the entire slope with a spraying thickness of 10-15cm to complete the repair of the mine slope.
