An anti-corrosion glue layer is arranged on the outer wall of the pipe pile main body 1, an alumina coating and a silicide metal coating are arranged on the outer wall of the end plate 2. Three reinforcing rings 3 are arranged on the pipe pile main body 1, a number of convex ribs 301 are arranged on the reinforcing rings 3, and an alumina coating and a silicide metal coating are arranged on the outer walls of the reinforcing rings 3 and the convex ribs 301.

[0030] In this embodiment, the pipe pile body 1 is cast from steel bars, steel strands and concrete in a forming mold. The anti-corrosion adhesive layer on the outer wall of the pipe pile body 1 can enhance the anti-corrosion performance of the prestressed pipe pile while also enhancing the strength of the prestressed pipe pile. The end plate 2, the reinforcing ring 3 and the convex ribs 301 are all made of metal materials. A first alumina coating is sprayed on the end plate 2, the reinforcing ring 3 and the convex ribs 301. Due to the good adhesion of alumina, the coating is firmly attached to the metal surface. Then, a silicide metal coating is sprayed.
