Pipe pile splicing device

Abstract

The invention discloses a pipe pile splicing device. The pipe pile splicing device comprises a plurality of pipe piles, wherein a clamping block is welded to the end of each pipe pile, a matching block which is connected and matched with the clamping blocks on the adjacent pipe piles is welded to the bottom of each pipe pile, a connecting column is arranged on the end surface of each clamping block in a protruding mode, connecting grooves into which the connecting columns on the adjacent pipe piles are inserted are formed in the bottom surface of each matching block in a sunken mode, a fixed groove is formed in the inner wall of the deepest position of each connecting groove in the sunken mode, the end, which is inserted into the corresponding connecting groove, of each connecting column is a fixed end, the fixed ends are inserted into the fixed grooves, fixed pieces which are used for limiting the connecting columns from being separated from the connecting grooves are arranged on the fixed ends, through holes through which external concrete is poured into the fixed grooves are formed in the peripheral walls of the matching blocks, and positioning pieces which are used for enhancing the connecting strength between the clamping blocks and the adjacent matching blocks and positioning the adjacent matching blocks are arranged on the clamping blocks. According to the pipe pile splicing device, the problems of low connecting strength between two pipe piles for pile splicing and complex pile splicing process in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of pipe pile connection, in particular to a pipe pile connection device. Background technique [0002] Pipe pile is a kind of prefabricated engineering pile. As the foundation material of buildings, it is driven into the ground by a pile driver in a specific geological environment. It acts under force in buildings and structures. There are two main uses of construction pipe piles. One is to transfer the weight of the upper building to the lower soil layer with high bearing capacity through pipe piles to improve the stability of the building; the other is to compact the soft soil layer so as to improve the bearing capacity of the foundation soil. The pile connection refers to the fact that the length of a pile does not reach the depth specified by the design, so it is necessary to connect the prefabricated piles one by one and continue driving down until they reach the designed depth. The process of connecti...
