AI Technical Summary

Technical Problem

During pipe jacking construction, the swaying of the hoisting ropes causes the casing to move in multiple positions, affecting the efficiency of the pipe jacking operation's docking.

Method used

Design a structure including an angle adjustment component and an auxiliary adjustment component. Utilize a support plate, a mounting plate, and an adjustment guide wheel. By adjusting the guide wheel and rolling it against the sleeve surface, the sleeve sway amplitude is reduced and the angle is adjusted. The auxiliary adjustment component provides secondary position guidance through a connecting rod and rollers.

Benefits of technology

This reduces the swaying amplitude of the casing during the lowering process, improves the efficiency of the casing docking with the hydraulic pipe jacking machine, and enhances construction efficiency and effectiveness.
