[0002] There are many types of slopes formed by mining, including mining slopes, spoil dump slopes, tailings dam slopes, transportation road slopes, etc. The movement of slope blocks due to various reasons, especially landslides and collapses, often pose a threat to production safety and people's lives and property. Therefore, in order to prevent the movement of slope rock and soil, and the movement of water with a large slope in rainy and snowy weather, which may cause damage to humans and the ecology, the slope protection project of the mine needs to design a slope protection device for mine ecological restoration.

The protective net 141 has mesh holes. The protective net 141 and the mesh holes are used to filter larger rocks and silt. A supporting rod 143 is set at the bottom of the protective net 141. The supporting rod 143 supports the drainage assembly. The bottom end of the drainage assembly is connected to the water storage tank 130. A top cover is set on the top of the water storage tank 130, which can be opened when it is necessary to deal with the internal silt and take out the internal accumulated water.

[0088] In this embodiment, the fixed structure 100 includes a compression anchor rod 106 and a second spring 104. When it is necessary to insert it into the foundation, the compression anchor rod 106 can drive the second spring 104 to be compressed together, and the needle-shaped anchor gun 105 connected to the lower end of the compression anchor rod 106 will be inserted deeply downward. An opening and closing rod 102 is provided at the bottom end of the needle-shaped anchor gun 105. When the fixed structure 100 penetrates deep into the foundation, the opening and closing rod 102 is closed by the squeezing force, and the opening and closing rod 102 is connected to the first spring 103. When the fixed structure 100 is completely immersed in the foundation, it only needs to be pulled upward, and the opening and closing rod 102 will open. The opening and closing rod 102 will be firmly fixed in the foundation under the influence of the first spring 103.

[0089] In this embodiment, the assembling portion 111 includes an assembling block 112 and a fixing buckle 113 . The fixing buckle 113 is disposed through the assembling block 112 .

[0090] In this embodiment, the drainage component includes a drainage tube 121 and a first filter structure 120. The first filter structure 120 is arranged in the drainage tube 121. The main material of the first filter structure 120 is PP cotton, which can play the first layer of filtration for the water quality. The drainage tubes 121 are combined side by side to form the overall frame of the drainage component.

[0091] In this embodiment, the water tank 130 includes an inner cavity and a box body. The inner cavity is arranged inside the box body. The four corners of the lower end of the box body are respectively connected to bases. A gripping cross bar is arranged in the middle of the bottom of the box body. The gripping cross bar is connected to the rotating shaft 136. The rotating shaft 136 is provided with a curved rake nail 135. The curved rake nail 135 is the main fixing component when the water tank 130 is fixed on the slope. It can be rotated and adjusted along with the rotating shaft 136. A fixed cross bar is arranged at the rear end of the bottom of the box body. Two support rods 137 are installed on the fixed cross bar.

[0094] In this embodiment, the specific operation steps are: first, align the protective rod 142 together with the fixed structure 100 with the foundation to be inserted, and insert the needle anchor gun 105 connected to the lower end of the compression anchor rod 106 downward to a depth, and the opening and closing rod 102 is closed by the extrusion force. When the fixed structure 100 is completely immersed in the foundation, it is pulled upward at this time, and the opening and closing rod 102 will open. The opening and closing rod 102 will be firmly rooted in the foundation under the influence of the first spring 103, and then the fixed structure 100 is at a certain distance from the protective rod 142 according to the above steps. Repeat the operation to make it firmly rooted in the foundation, and then use the connecting rope 101 to connect it to the fixing buckle 113 of the assembly part 111, and the installation steps are completed. When it rains, water will flow into the water tank 130 through the drainage assembly supported by the supporting rod 143. In this process, the first filter structure 120 plays the role of the first layer of filtration. After the water flows into the water tank 130, the sediment baffle 131 plays the role of the second layer of filtration. Finally, it will pass through the double-layer filter net 132 for the final filtration before storage, thus forming clean water quality for drinking.
