STEEL WALL AND MANUFACTURING METHOD FOR IMPROVING WATERPROOFING EFFICIENCY BY FORMING AUTOMATIC WELDING SPACE OF JOINT PART IN MANUFACTURING STEEL WALL BY CONNECTING STEEL MATERIAL

摘要

PURPOSE: A steel wall and a manufacturing method thereof are provided to improve waterproofing efficiency and construction efficiency, and to cut down construction cost by forming the automatic welding space of the joint part and linearly connecting plural asymmetrical U-shaped steel sheets. CONSTITUTION: A steel sheet wall is constructed(a), and a temporary steel sheet is constructed(b). A closed section is formed and surrounded by the part of the steel sheet wall and the temporary steel sheet(c). Earth or sand is excavated and removed from the closed section(d), and a joint part of the steel sheet wall is washed and cleaned in the closed section(e). An automatic welding machine is set in the closed section(f), and welding is automatically performed(g). The temporary steel sheet is removed after securing waterproofing(h). The waterproof steel wall is constructed by repeating the steps.
