AI Technical Summary

Technical Problem

In the construction of pile foundation engineering, when the steel cage segments are connected, a single steel pipe or wooden beam is difficult to support the weight of the multi-section steel cage, and is prone to bend or broken, causing the steel cage to fall off and affect the connection work.

Method used

A new type of cast-injected pile steel cage wellhead support is designed, including an outer frame and a support component. The support component consists of a support rod, a reinforcement plate, a fixing plate, a support rod fixing member, etc. It distributes the ground pressure through the outer frame, and hooks the steel cage through the support rod. The support rod fixing member fixes the support rod to ensure that the support is not easily deformed.

Benefits of technology

It effectively solves the problem that a single steel pipe or wooden beam cannot support a multi-section steel cage, ensures that the steel cage does not fall off during the connection process, improves the reliability and safety of the connection work, and can be reused multiple times.

Abstract

The novel cast-in-place pile reinforcement cage well mouth support comprises an outer frame, supporting assemblies are arranged at the four corners of the upper surface of the outer frame, each supporting assembly comprises two supporting rods, reinforcing plates and a fixing plate, the reinforcing plates are arranged at the upper ends and the lower ends of the two supporting rods, and the fixing plates are welded to the rear ends of the supporting rods. The supporting rod fixing piece is arranged between the supporting assembly and the outer frame and comprises fixing blocks, limiting columns and reinforcing rods, the fixing blocks are welded to the four corners of the upper surface of the outer frame, the limiting columns transversely penetrate through the fixing blocks, and the reinforcing rods vertically penetrate through the outer ends of the limiting columns. The outer frame is arranged to disperse ground pressure and is used in a construction site in a turnover mode, the supporting rods on the outer frame are used for hooking the reinforcement cage, the supporting rods are fixed and limited through the supporting rod fixing pieces, and therefore the support is not prone to deformation and can be used repeatedly.
