Abstract

The invention provides a precast concrete pipe pile. The precast concrete pipe pile comprises at least two hollow concrete pipe pile sections sequentially distributed from top to bottom and a pile section connecting device used for connecting the every two adjacent concrete pipe pile sections, the precast concrete pipe pile comprises a plurality of steel bars arranged on the inner walls of the concrete pipe pile sections and arranged in the axial direction, and end plates arranged at the ends of the concrete pipe pile sections, each pile section connecting device comprises a connecting ring plate with the same outer diameter as the two adjacent concrete pipe pile sections, clamping devices protruding outwards are fixedly arranged at the upper end and the lower end of the center of each connecting ring plate, a plurality of through holes I are evenly formed in each connecting ring plate, a blocking piece is arranged in the middle of the interior of each through hole I, and each blockingpiece is made of silumin which is used for being bonded with the steel bars protruding out of the ends of the two concrete pipe pile sections in a heating state. The precast concrete pipe pile is simple in structure and convenient to use, and the connecting strength between the adjacent concrete pipe pile sections is improved.

Description

Technical field [0001] The present invention relates to the technical field of engineering piles, in particular a prefabricated concrete pipe pile.
