Precast concrete pipe pile

The prefabricated concrete pipe pile comprises a shell, two annular steel blocks are symmetrically installed in an inner cavity of the shell up and down, a plurality of auxiliary steel bars are evenly distributed and installed between the two annular steel blocks, and bundle penetrating holes matched with steel strands in the prefabricated concrete pipe pile for use penetrate through the top face provided with the shell to the bottom face. Clamping piece grooves are formed between the shell and the annular steel block and located in the upper end and the lower end of the bundle penetrating hole, conical clamping pieces are installed in the clamping piece grooves, and the conical clamping pieces at the upper end and the lower end are arranged in a staggered mode, that is, in the same bundle penetrating hole, the conical clamping piece is installed in the clamping piece groove at the upper end, or the conical clamping piece is installed in the clamping piece groove at the lower end.
