Abstract

The invention discloses a prestressed concrete pipe pile anticorrosion joint, which is characterized by comprising an end plate and a connection flange, wherein, the connection flange is provided with a rib frame; the end plate is provided with a plurality of screw holes; and the connection flange is also provided with a plurality of bolt interpenetration positions corresponding to the screw holes. By adopting the anticorrosion joint provided by the invention, the influence of the friction extrusion process of geological environments on anticorrosion measures in construction can be avoided, the service life of the pipe pile foundation is effectively prolonged, and the safety of the engineering is ensured; and meanwhile, the performances, such as shear resistance and bending resistance and the like of a pipe pile connection structure at the joint are ensured, the connection is stable and firm, and the quality and the safety in construction and using process of the pipe pile are ensured.

Description

technical field [0001] The invention relates to a joint, in particular to a prestressed concrete pipe pile anticorrosion joint. Background technique [0002] In the past ten years, pipe piles have been widely used in the construction field due to their high bearing capacity, low engineering cost and short construction period. Pipe piles are prefabricated parts, and each section of pipe piles needs to be spliced ​​during construction. With the expansion of the application field of pipe piles, the connection between pipe piles faces a problem of anti-corrosion in a corrosive environment. The traditional connection between the pipe piles is to weld the two pipe pile end plates into one body by electric welding at the groove of the pipe pile end plates. The direct welding between the end plates is difficult to guarantee the quality of the construction due to the small spacing, narrow welds, and differences in the level of welders. It is easy to cause safety hazards to the proj...
