Occlusion pile flat cage hoisting-placing deviation-rectifying device

Abstract

The invention discloses an occlusion pile flat cage hoisting-placing deviation-rectifying device. The occlusion pile flat cage hoisting-placing deviation-rectifying device comprises a rod body and a sliding device, wherein the rod body is a cylindrical rod, and the section of the rod body is provided with three sets of sliding grooves in the axial direction, the two ends of the rod body are provided with skid resistant layers correspondingly, the middle of the rod body is fixedly connected with a blocking block in a sleeved manner, the sliding device is composed of an axial sliding bearing setand a radial rotating bearing, the axial sliding bearing set comprises an annular connection shaft and auxiliary bearings, the auxiliary bearings are arranged three sets, and the auxiliary bearings are evenly distributed on the section of the annular connection shaft, the section of the radial rotating bearing is provided with a closed groove in the circumferential direction, and the middle of the radial rotating bearing is provided with sliding steel ball bodies, and the inner wall of the radial rotating bearing is provided with three sets of grooves. By means of the occlusion pile flat cagehoisting-placing deviation-rectifying device, guarantee of the protective layer thickness of a reinforced concrete structure is facilitated, on the other hand, relative to manual deviation-rectifying, labor can be saved, and the labor intensity is lowered.

Description

technical field [0001] The invention belongs to the technical field of occlusal piles, in particular to a deflection correcting device for hoisting and placing flat cages of occlusal piles. Background technique [0002] As a supporting enclosure structure, the occlusal pile is widely used in the enclosure construction of deep foundation pits such as subway stations. The design of occlusal piles is divided into two types, A pile and B pile. Among them, the reinforcement cage of A pile is set as a round cage, and the common diameters are 1200mm and 1000mm; B pile has two types, one is plain pile, and the other is reinforced cage concrete. pile, the latter pile reinforcement cage is set as a flat cage, and the present invention mainly solves the problem of hoisting the latter B pile reinforcement cage; [0003] The construction sequence of the occlusal piles is as follows: use casing to protect the wall to form holes, first construct B piles at intervals, and use hydraulic cas...

AI Technical Summary

Problems solved by technology

During the construction of B-piles, since the reinforcement cage of B-piles is square, the self-balancing performance is poor, especially in the lower process.

[0004] However, in the prior art, problems such as the deviation between the center of the steel cage and the center of the pile, and the deviation of the steel cage to one side of the pile are prone to occur.

When the reinforcement cage is biased towards the side of the pile, it is easy to cause the concrete to not completely wrap the reinforcement cage during concrete pouring, and the thickness of the protective layer is insufficient. On the other hand, when manually correcting the deviation, labor is wasted and labor intensity is increased.
