[0002] After mining activities are completed, engineering, biological, and chemical technologies are generally used to restore and repair the land, vegetation, soil and water, and geological environment damaged by mining, in order to restore the ecological environment and prevent soil erosion and geological disasters. Mine reclamation, restoration and protection have many aspects, one of which is slope protection. A common slope protection measure is to install slope protection nets, which are usually installed using anchoring methods.

[0003] In outdoor rockfall situations, slope protection nets may suffer localized damage, leading to problems such as partial loss of protection, concentrated stress at the damaged area, and slope protection faults. To prevent the stress from spreading at the localized cracks in the slope protection nets, it is necessary to repair and reinforce those locally damaged areas.

[0004] In the existing mine reclamation and restoration, when slope protection nets are used, in order to avoid the local cracks in the slope protection nets being stressed and torn further, this application proposes a protective device for mine reclamation and restoration. Utility Model Content

A winding post 24 is fixed on the mesh plate 21, and the anchor rod 23 is inserted into the slope soil. The mesh plate 21 and the slope protection wire mesh are firmly secured by wire winding. The mesh plate 21 is woven and wound with wire, possessing flexibility, and its geometric curve can be changed according to actual conditions to conform to the slope and the protection wire mesh. The winding post 24 is used to change the direction of the reinforcing steel cable 6. In addition, the winding post 24 also acts as an anchor point to anchor the reinforcing steel cable 6. It also includes a sturdy component for anchoring the corners of the protective net 1, including a reinforcing mesh plate 71 that is twisted and wrapped with the protective net 1 with steel wire mesh, and a locking anchor rod 72 that penetrates the reinforcing mesh plate 71. The locking anchor rod 72 penetrates the protective net 1 and is inserted into the slope to anchor and reinforce the corners of the protective net 1. It also includes a reinforcing steel cable 6 for reinforcing the locking anchor rod 72 and the winding post 24. The reinforcing steel cable 6 reinforces the locking anchor rod 72 and the winding post 24, keeping the locking anchor rod 72 and the winding post 24 in a connected state to prevent loosening due to stress at a single location.

[0018] In this embodiment, a semi-circular ring-shaped wire loop 73 is fixed on the surface of the reinforcing mesh plate 71. The reinforcing steel cable 6 passes through the wire loop 73 and is wrapped around the wire loop 73. The wire loop 73 restricts the reinforcing steel cable 6.

[0019] In this embodiment, a pressing circular plate 721 is welded onto the locking anchor rod 72. The surface of the pressing circular plate 721 matches the surface of the reinforcing mesh plate 71. The locking anchor rod 72 anchors and limits the pressing circular plate 721 to prevent the pressing circular plate 721 from loosening.

[0020] In this embodiment, a limiting circular plate 221 is welded to the outer side of the bottom end of the limiting circular tube 22. The limiting circular plate 221 matches the bonding mesh plate 21, and the limiting circular tube 22 and the limiting circular plate 221 serve as anchor points to reinforce the bonding mesh plate 21.
