At present, steel materials are often used to make underground continuous walls in the construction process. Compared with traditional concrete walls, steel underground continuous walls have higher strength and flexibility, and can better adapt to stress changes under complex geological conditions. However, in the construction of conventional steel continuous walls, adjacent U-shaped steels are usually paired and inserted into the ground through corresponding hook-shaped structures, and purlins are set up between the continuous walls on both sides. The connection between the inverted adjacent U-shaped steels is not stable enough and is prone to separation. Utility Model Content
