PROBLEM TO BE SOLVED: To provide an underground wall enabling a working efficiency to be improved when steel sheet piles are disposed in an excavated hole by their sinking and also enabling the flexibility of arrangement of the steel sheet piles to be increased. SOLUTION: The excavated hole 13 is filled with a slurry or liquid secular hardener 14. A plurality of steel sheet piles 10 are disposed in the excavated hole 13 filled with the secular hardener 14 without engaging the joint parts 24 thereof with each other. The underground wall 1 is built by solidifying the secular hardener 14. COPYRIGHT: (C)2010,JPO&INPIT
