Precast concrete pipe pile

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. Background technique [0002] A pre-concrete pipe pile provided by the CN105113503B, including at least two concrete pipe pile sections from the top down, and a pile-segment connection mechanism for connecting adjacent concrete pipe pile sections, a pile segment connection The agency includes a connecting plug and connecting holder, the connection plug is fixed to the end of the concrete pipe pile section, the connecting seat is fixedly disposed at the end of the other concrete pipe pile segment, the connection plug is inserted into the connecting seat, connecting the plug A plurality of radial projections are provided, and an annular fixing groove in which an elastic connection pin is provided on a connecting seat, an elastic connection pin is provided in an annular fixed recess. When the above device is connected, it is only necessa...

AI Technical Summary

Problems solved by technology

When the above device is connected, it is only necessary to insert the connecting plug into the connecting seat, and the elastic connecting pin is clamped in the annular fixing groove, which is convenient to operate, but the connection between the two adjacent concrete pipe pile sections is not stable enough, and there are potential safety hazards
