RECYCLABLE STEEL GUIDE WALL

WIPO Patent Application WO/2023/097947

A1

The present invention provides a recyclable steel guide wall, comprising four side plates. The four side plates are sequentially connected end to end and define a closed frame body, and a positioning hole is formed in the center of the closed frame body. The closed frame body is defined by the four side plates. The closed frame body is installed at the tops of two adjacent pile foundations. The positioning hole at the inner side of the closed frame body provides a positioning effect for construction of a second-stage slot, that is, a slot milling machine passes through the positioning hole and performs slot milling along the contour of the positioning hole, and the same positioning effect is achieved with a concrete guide wall. However, the steel guide wall is made of a steel material, and is light in weight. The steel guide wall can be integrally disassembled and transferred after construction of the second-stage slot is completed, the steel guide wall can be repeatedly used, and the construction costs are greatly saved; the steel guide wall is of an integrated structure, facilitating recycling, disassembly and assembly are convenient, and the construction efficiency is improved.
