Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile joints, and particularly relates to a prestressed concrete pipe pile pin joint. Background Technique

[0002] In the past decade or so, pipe piles have been widely used in the construction field due to their high single-pile bearing capacity, low project cost, short construction period and other characteristics. Pipe piles are prefabricated components, and each section of pipe pile needs to be spliced during construction. With the expansion of the application field of pipe piles, the connection between pipe piles faces an anti-corrosion problem in a corrosive environment.

[0003] For example, the Chinese patent with the publication number CN202164600U proposes a precast prestressed concrete pipe pile splicing structure. The assembly includes a lower pile section and an upper pile section. The ends of the lower pile section and the upper pile section are both pile end plates with a number of self-retaining holes, and also include pins corresponding to the number of self-retaining holes. The pins are inserted into the self-retaining holes of the lower pile section and the upper pile section. Compared with the prior art, this process has significant advantages over the traditional pile splicing process in terms of quality and operation: the construction is simple and easy to operate. Construction workers do not need to master complex construction techniques to carry out construction operations. The shear and bending resistance of the joint are greatly enhanced, improving the joint quality. Compared with the traditional pile splicing process, the operation time of each joint only increases by about three minutes. Using round steel pins enables the upper and lower pile sections to be vertically butted, reducing the degree of pile inclination;

[0004] However, in the actual application process of this scheme, since the bolts are directly exposed to the underground environment, the gap structure between the bolts and the joint rusts and corrodes, thus affecting the later service life of the pipe pile.

[0005] Therefore, how to design a prestressed concrete pipe pile pin joint has become a problem that needs to be solved currently. Content of the Utility Model
