[0024] The embedding grooves 7 are evenly distributed inside the ground nail 4 , and the second hooking barbs 5 are evenly and symmetrically distributed about the central axis of the ground nail 4 .

[0025] The sealing blocks 8 are symmetrically distributed about the central axis of the limiting plate 11 , and the inner diameter of the embedding groove 7 is larger than the outer diameter of the embedding block 6 .

[0026] The outer diameter of the second adsorption block 10 is the same as the inner diameter of the embedding groove 7 , and adsorption positioning is formed between the first adsorption block 9 and the second adsorption block 10 .

[0027] The ground nails 4 are symmetrically distributed about the central axis of the geogrid body 1 , and the cap heads 3 are fixed to the ground nails 4 by welding.

[0028] A first hook 2 is fixed to one end of the geogrid body 1 . The first hook 2 is evenly distributed on one end of the geogrid body 1 and is of a conical design.

[0029] The outer side wall of the geogrid body 1 is coated with an anti-corrosion layer 12 , and the outer side wall of the anti-corrosion layer 12 is fixed with a wear-resistant layer 13 .

[0030] The coating surface areas of the anti-corrosion layer 12 and the wear-resistant layer 13 are the same, and the anti-corrosion layer 12 and the wear-resistant layer 13 are coated on the same vertical section;

[0031] Furthermore, the geogrid body 1 can be made of common polypropylene or polyvinyl chloride through thermoplastic or molding process;

[0032] Furthermore, the anti-corrosion layer 12 can be formed by spraying epoxy coating to form an anti-corrosion work, while the wear-resistant layer 13 can be formed by spraying plastic coating, which is a process of spraying plastic particles onto the surface of the substrate to form a protective layer.

[0035] Working principle: First, during operation, the anti-corrosion layer 12 is coated on the outer wall of the geogrid body 1, so that the anti-corrosion ability is improved to a certain extent based on the coating of the anti-corrosion layer 12 during operation. At the same time, under the coating of the wear-resistant layer 13, the wear-resistant layer 13 is located at the outermost coating to form wear-resistant protection. Then the geogrid body 1 is composed of horizontal bars and vertical bars, and then the first hook 2 is evenly distributed on the end face of the geogrid body 1, and the embedded block 6 is embedded in the embedded groove 7, and a certain sealing protection is formed by the sealing block 8. After the embedded block 6 is embedded in the embedded groove 7, the first adsorption block 9 and the second adsorption block 10 cooperate to perform adsorption positioning to complete the installation and fixation of the second hook 5. Therefore, when the geogrid body 1 is working, the first hook 2, the ground nail 4 and the second hook 5 cooperate to complete the reinforcement work.
