The pipe pile needs to be used with the end plate to facilitate the connection and sealing between the pipe piles.

[0003] The prior art with the authorization publication number CN218409011U discloses a pipe pile end plate structure, which comprises an end plate body, a trumpet ring opening is arranged on the right side of the end plate body, an annular skirt is fixedly connected to the surface of the end plate body, a reinforcing layer is fixedly connected to the inside of the end plate body, a core layer is fixedly connected to the inside of the reinforcing layer, and an anti-deformation layer is fixedly connected to the right side of the core layer. The utility model solves the problem that most pipe pile end plates on the market do not have high strength, which leads to deformation and indentation of the pipe pile end plate during long-term use, making the pipe pile end plate unable to be used normally, and causing water leakage and air leakage, which affects the normal use of the pipe pile end plate. The effect of high strength and long service life is achieved. The pipe pile end plate can prevent water leakage and air leakage due to deformation during use by improving the strength of the end plate.
