PURPOSE:To easily drawn out steel sheet piles by a method in which a steel sheet pile is cut off in the longitudinal direction at the center of its widthwise direction and a coupler and a sealing member are provided to the cut parts in such a way as to reduce the horizontal pulling force of the sheet pile. CONSTITUTION:A steel sheet pile 6a is cut off in the longitudinal direction at the center of its widthwise direction, and a U-shaped coupler 6c whose outside is opened is fixed to the end face of one cut part 6b. The other cut part 6d is inserted into the coupler 6c. Two steel bars 15 covered with a sealant 14 are airtightly inserted between the coupler 6c and the cut part 6d to form a steel sheet pile 6a of almost the same shape as the sheet pile 6. The piles 6a are connected and inserted into a or several places of the sheet pile 6 in such a way as to reduce the horizontal pulling force of the pile 6. In drawing out the piles, the bars 15 are pulled out in advance for loosening between the coupler 6c and the cut part 6d, and then the piles 6a are drawn out. |
