Abstract

The invention discloses a connecting structure for concrete pipe pile installation. The connecting structure comprises a horizontally arranged installation base, the installation base is fixedly connected with the ground, the installation base is in a semi-open cylinder shape, a plurality of concrete pipe piles are vertically arranged above the installation base, the concrete pipe piles are in a circular ring shape, first connecting grooves are formed in the bottom faces of the multiple concrete pipe piles, connecting rings are fixedly connected to the upper surfaces of the multiple concrete pipe piles, the first connecting grooves are in a ring shape matched with the connecting rings, the multiple concrete pipe piles are connected end to end, second connecting grooves are formed in the inner bottom face of the installation base, and the second connecting grooves are in a ring shape matched with the connecting rings. Traditional screws and nuts are replaced by a clamping mode, so that the device is more convenient to connect and fix, meanwhile, the connecting strength is not affected by corrosion, the concrete pipe piles are decomposed into a multi-section structure, transportation is facilitated, meanwhile, installation is more convenient and safer, and practicability is higher.

Description

technical field [0001] The invention relates to the technical field of concrete pipe piles, in particular to a connection structure for installing concrete pipe piles. Background technique [0002] At the end of the 1960s, the Fengtai Bridge Factory of the Ministry of Railways began to produce pre-tensioned prestressed concrete pipe piles (referred to as PC pipe piles), which were mainly used for the foundation construction of railway bridge projects. In the 1970s, post-tensioned prestressed concrete pipes were developed and produced. pile. [0003] Most of the existing concrete pipe piles are fixedly connected by screws. This connection method is easy to affect the connection effect due to corrosion over time, and most of the existing concrete pipe piles are monolithic structures with large lengths, making Both installation and transportation are troublesome. Therefore, in order to solve the above problems, a connection structure for installing concrete pipe piles is propo...
