Installation device for prefabricated pipe pile and pile cap in municipal engineering

Abstract

The invention discloses a municipal engineering prefabricated pipe pile and pile cap mounting device. A support is arranged above the pipe pile; a positioning plate is arranged above the support; a fixing sleeve of the pile cap is placed in a mounting hole of the positioning plate, a ball is arranged on the surface of the positioning plate and abuts against a top plate of the pile cap, a deviationrectifying mechanism is arranged in the support to rectify the pile cap, the positioning plate can move towards two sides, and after the pile cap is aligned with the pipe pile, the pile cap can fallon the pipe pile by moving the positioning plate to achieve positioning and mounting. A mounting groove of the pile cap can be accurately aligned with the pipe pile, the pile cap can be stably put down, and the mounting efficiency and the construction quality are improved.

Description

Technical field [0001] The invention relates to the technical field of building foundation construction, in particular to an installation device for municipal engineering prefabricated pipe piles and pile caps. Background technique [0002] For railway, highway and other soft soil foundation projects, controlling the settlement deformation of the foundation mainly refers to controlling the post-construction settlement, which is to control the post-construction settlement within the standard range. At present, foundation treatment projects generally adopt prefabricated pipe piles for reinforcement. After the completion of the precast pile construction, in order to solve the problem of the transmission of the upper load to the lower pile foundation, a pile cap is set on the pile top to make the force of the foundation soil more uniform, so that the settlement of the foundation can be effectively controlled. [0003] At present, the Chinese patent document with application publicatio...

AI Technical Summary

Problems solved by technology

[0004] The installation of the existing prefabricated pile caps and pipe piles mainly has the following problems: the pile cap has a relatively large weight, and is usually installed by a crane, but the diameter of the installation groove left under the fixing sleeve for fitting with the pipe pile is usually It is only slightly larger than the outer diameter of the pipe pile, which makes it difficult for the mounting groove of the pile cap to be directly aligned with the pipe pile during the hoisting process, requiring repeated manual adjustments, and it is easy to cause bumps between the pile cap and the pipe pile, which may cause damage
