AI Technical Summary

Technical Problem

During the construction of sheet pile driving, uneven geological conditions lead to differences in the distribution of resistance to pile penetration, and insufficient positioning accuracy of the driving guide device results in excessive verticality and deviation of the sheet pile, affecting construction quality and efficiency.

Method used

A combination device consisting of a guide bracket, a receiving frame, a receiving rod, and auxiliary components is used. The first auxiliary component positions the inserted steel sheet pile, while the second auxiliary component guides it, enabling rapid switching and continuous operation of the steel sheet piles and ensuring verticality and positional accuracy.

Benefits of technology

It improves the construction accuracy and efficiency of sheet pile driving, avoids deviation and misalignment, and enhances the water-stopping and seepage prevention effect of the foundation pit and the stress performance of the retaining structure.
