[0007] As a preferred technical solution of the utility model, a pipe pile head is installed at the bottom end of the pipe pile body, and the pipe pile head is conical.

[0008] As a preferred technical solution of the utility model, the bottom end surface of the mounting flange is provided with a thread groove matching the thread.

[0009] As a preferred technical solution of the present utility model, the size of the mounting hole is equal to that of the through hole.

[0010] As a preferred technical solution of the utility model, an anti-rust layer is provided on the surface of the mounting flange.

[0011] The beneficial effects of the utility model are:

[0012] 1. By using the baffle plate in conjunction with the push block, the push block pushes the baffle plate to rotate in the chamber, so that the baffle plate can block the installation hole, thereby preventing the installation hole from being blocked by soil or other impurities, affecting the subsequent work efficiency and connection effect when connecting with other construction parts.

[0019] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] Example: Figure 1-4 As shown, the utility model is a prefabricated PHC pipe pile, including a pipe pile body 1, a connector 2 is installed on the top of the pipe pile body 1, a thread 12 is provided on the surface of the connector 2, a mounting flange 3 is connected to the thread 12 of the connector 2, a plurality of mounting holes 4 are provided on the upper end surface of the mounting flange 3, a chamber 5 is provided on one side of the mounting hole 4, a baffle 6 is movably connected in the chamber 5, a through hole 7 equal to the number of the mounting holes 4 is provided on the surface of the baffle 6, a push block 8 is installed on one side of the baffle 6, a groove 9 is provided on one side of the chamber 5, and one end of the push block 8 passes through one side of the groove 9 and extends to the outside.
