Cast-in place pile reinforcing cage mounting and positioning method and auxiliary device used for cast-in place pile reinforcing cage mounting and positioning method

Abstract

The invention provides a cast-in place pile reinforcing cage mounting and positioning method and an auxiliary device used for the cast-in place pile reinforcing cage mounting and positioning method. According to the cast-in place pile reinforcing cage mounting and positioning method, a positioning clamp frame is used for supporting, positioning and fixing a cast-in place pile reinforcing cage in acast-in place pile guide pipe. The positioning clamp frame is composed of a first fixed casing pipe, a second fixed casing pipe, two supporting rods, a middle casing pipe, a pipe body, an extension pipe, a fixing clamp bolt and a wheel, wherein the middle casing pipe is arranged at the rear end of the pipe body, the rear end of the extension pipe is inserted into the front end of the pipe body, the fixing clamp bolt is inserted into a fixing hole and a corresponding adjustment hole to fix the rear portion of the extension pipe in the pipe body, and the other ends of the two supporting rods obliquely extend outwards and are correspondingly connected with the first fixed casing pipe and the second fixed casing pipe. The cast-in place pile reinforcing cage mounting and positioning method andthe auxiliary device used for the cast-in place pile reinforcing cage mounting and positioning method have the advantages that the cost is low, operation is easy, labor and time are saved, the applicability is high, the mounting and positioning quality and speed of the cast-in place pile reinforcing cage are improved, the construction efficiency is improved, the construction period is shortened,and the using effect is good.

Description

technical field [0001] The invention belongs to a method for installing and positioning a reinforced cage of a bored pile and an auxiliary device thereof. Background technique [0002] At present, most bridge engineering projects involve the construction of bored piles. During the concrete pouring process of bored piles, the lifting of the pile conduit and the concrete jacking construction process can easily cause the reinforcement cage of the cast-in-place pile located in the pile conduit. Deviation, the deviation of the cast-in-situ pile reinforcement cage leaves quality and safety hazards for the subsequent construction of bridge piers and abutments. [0003] Secondly, the installation and positioning of cast-in-place pile reinforcement cages in the pile foundation on site mostly adopts welding the steel bar heads on the cast-in-place pile reinforcement cages or welding the cast-in-place pile reinforcement cages to the casing with auxiliary steel bars. This method is not ...

[0002] At present, most bridge engineering projects involve the construction of bored piles. During the concrete pouring process of bored piles, the lifting of the pile conduit and the concrete jacking construction process can easily cause the reinforcement cage of the cast-in-place pile located in the pile conduit. Deviation, the deviation of cast-in-situ pile reinforcement cage leaves quality and safety hazards for the subsequent construction of bridge piers

[0003] Secondly, the installation and positioning of cast-in-place pile reinforcement cages in the pile foundation on site mostly adopts welding the steel bar heads on the cast-in-place pile reinforcement cages or welding the cast-in-place pile reinforcement cages to the casing with auxiliary steel bars. This method is not only time-consuming, but also ineffective and difficult. Fast and accurate positioning of cast-in-situ pile reinforcement cages in cast-in-place pile conduits on site
