PURPOSE: To prevent pollution of water quality by filling fills to the inside of a driven sheet pile and, at the same time, clamping the sheet pile from the peripheral surface thereof with tension cables.
CONSTITUTION: Tension cable anchorages, a leading-in metal fixture and spacer, etc., are mounted to a sheet pile 1 such as a steel pipe sheet pile, etc., in advance. After that, in the sea, river and lake, etc., the sheet piles 1 are driven continuously to the foundation 4. Then, the inside partitioned by the continuous sheet piles 1 is filled with fills 2 such as strength improved soil, etc. After tension cables 5 are arranged to the peripheral surface of the sheet pile 1, and tensile force is given to the cables 5 to clamp the sheet pile 1 from the peripheral surface thereof. In addition, after an underground continuous wall 3 is executed, the tensile force of the cables 5 is removed.
