[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In one embodiment, see Figures 1-4A device for repairing pile foundations using a fiberglass sleeve includes a pile foundation 1, a reinforcing layer 4 covering the outside of the pile foundation 1, a silicone layer 3 covering the outside of the reinforcing layer 4, and an anti-corrosion layer 2 covering the outside of the silicone layer 3. A clamping assembly is provided on the outside of the anti-corrosion layer 2. A sealing ring 9 is provided on the outside of the pile foundation 1. The reinforcing layer 4 is fixedly bonded to the silicone layer 3 with polyurethane adhesive, and the anti-corrosion layer 2 is fixedly bonded to the outer wall of the silicone layer 3 with polyurethane adhesive. The silicone layer 3 is made of silicone resin and silicone rubber, and the anti-corrosion layer 2 is made of epoxy resin and polytetrafluoroethylene. The reinforcing layer 4 possesses excellent strength and provides good support for the silicone layer 3 and the anti-corrosion layer 2. The silicone layer 3 has good toughness and resilience, effectively absorbing external forces and reducing damage to the pile foundation 1. The anti-corrosion layer 2 effectively protects the silicone layer 3 and the reinforcing layer 4 from external air corrosion. The outer wall of the sealing ring 9 is set on the outer wall of the anti-corrosion layer 2, the silicone layer 3, and the reinforcing layer 4. The outer wall of the threaded cap 8 of the sealing ring 9 is set on the outer wall of the connecting plate 6 to prevent external moisture from entering and causing moisture to corrode the silicone layer 3, the reinforcing layer 4, and the aramid fiber and rubber pile foundation 1. Through the mutual cooperation between the anti-corrosion layer 2, the silicone layer 3, the reinforcing layer 4, and the sealing ring 9, the pile foundation 1 is protected from external corrosion, the damage caused by external impact is reduced, and the service life of the pile foundation 1 is extended.

[0020] In one embodiment, the clamping assembly includes a clamping block 5 sleeved on the outside of the anti-corrosion layer 2. A connecting plate 6 is provided at the end of the clamping block 5, and a threaded hole 10 is provided on the connecting plate 6. A threaded rod 7 is threadedly connected to the threaded hole 10, and a threaded cap 8 that mates with the connecting plate 6 is threadedly connected to the end of the threaded rod 7. The clamping assembly is provided on the outer wall of the anti-corrosion layer 2, and a threaded rod 7 is threadedly connected to the inner wall of the clamping assembly. A threaded cap 8 is threadedly connected to the outer wall of the threaded rod 7. The clamping assembly includes a clamping block 5, the outer wall of which is disposed on the outer wall of the anti-corrosion layer 2.

The clamping block 5 is placed on the outer wall of the anti-corrosion layer 2. The threaded rod 7 is rotated so that it is fixed to the inner wall of the connecting plate 6 through the threaded hole 10. The threaded rod 7 is then fixed by the threaded cap 8. Through the cooperation between the clamping block 5, the connecting plate 6, the threaded rod 7 and the threaded cap 8, the connection between the anti-corrosion layer 2, the silicone layer 3, the reinforcing layer 4 and the pile foundation 1 is clamped and fixed, preventing the entry of external air and moisture due to gaps caused by long-term use, and improving the efficiency of the anti-corrosion layer 2, the silicone layer 3 and the reinforcing layer 4.

[0021] In this embodiment, the clamping block 5 is first placed on the outer wall of the anti-corrosion layer 2, and then the threaded rod 7 is fixed to the inner wall of the connecting plate 6 through the first threaded hole 10. After the threaded rod 7 is fixed, the threaded rod 7 and the connecting plate 6 are reinforced by the threaded cap 8, thereby achieving clamping and fixing between the anti-corrosion layer 2, the silicone layer 3, the reinforcing layer 4 and the pile foundation 1, preventing gaps from forming at the connection after long-term use, and greatly improving the working efficiency of the anti-corrosion layer 2, the silicone layer 3 and the reinforcing layer 4.

[0022] This utility model provides a device for repairing pile foundations with fiberglass sleeves. The fiberglass sleeves can not only reduce the damage to the pile foundation 1 caused by external corrosion and forces through the cooperation between the anti-corrosion layer 2, silicone layer 3, reinforcing layer 4 and sealing ring 9, but also clamp and fix the anti-corrosion layer 2, silicone layer 3, reinforcing layer 4 and pile foundation 1 through the clamping block 5, so as to avoid the formation of gaps between the anti-corrosion layer 2, silicone layer 3, reinforcing layer 4 and pile foundation 1 due to long-term use, thereby improving the efficiency of the anti-corrosion layer 2, silicone layer 3 and reinforcing layer 4.
