AI Technical Summary

Technical Problem

Existing positioning devices are difficult to apply to variable cross-section cast-in-place piles, resulting in inaccurate lowering of the reinforcing cage, affecting the stability of the pile foundation structure and increasing construction time and costs.

Method used

A rebar cage positioning device including a laser emitter and a track was designed. It can be adjusted according to the cross-sectional size of the rebar cage. By setting up a device, rapid positioning of the rebar cage is achieved during use. The device involves a technical solution, including a rebar cage positioning device with a laser emitter and a track, which can adapt to rebar cages with different cross-sectional sizes. Rapid and accurate positioning is achieved by adjusting the position of the laser emitter.

Benefits of technology

It significantly improves the efficiency of lowering the rebar cage, reduces construction time, increases construction efficiency, and reduces costs.

Abstract

This invention discloses a rebar cage positioning device and a rebar cage lowering method, solving the technical problem of inconvenience in using existing rebar cage positioning devices. The rebar cage positioning device includes: a first disc, installed above the pile foundation entrance; the first disc has a channel adapted to the cross-sectional dimensions of the rebar cage; laser emitters, the working ends of which face the interior of the pile foundation, and at least two laser emitters, the center formed by the at least two laser emitters being the pile foundation axis or the rebar cage axis; and a track adapted to the number of laser emitters, allowing the laser emitters to move along the track; one end of the track is connected to the first disc, and the other end extends from the outer edge of the channel towards the center.
