PROBLEM TO BE SOLVED: To provide a method for constructing a wall body or a columnar body in the ground, reusable even for the next excavated excavation hole by filling the inside of the excavation hole with slurry in a state of mixing little excavation earth. SOLUTION: When creating the excavation hole, the excavation earth moves to the aboveground side by excavation. The excavation hole is created in the prescribed depth by using an excavator capable of blocking up the excavated excavation hole by the excavation earth moving to this aboveground side and the excavator itself. Next, the slurry is filled in a state of mixing little the excavation earth in the lower excavation hole of the excavator by delivering the slurry from the lower side of the excavator while pulling up the excavator to an upper part in a state of blocking up the excavated excavation hole by the excavation earth existing in a side part of the excavator and the excavator itself. Next, a water impermeable bag body is inserted into the excavation hole, and a filler is filled in the bag body. The bag body is set in a figure corresponding to a shape of the excavation hole, and the slurry is discharged on the ground in a state of mixing no foreign matter. COPYRIGHT: (C)2005,JPO&NCIPI
