PURPOSE:To easily and exactly correct by moving of a buried object under the ground by a method in which pressure water is jetted in the predetermined direction of moving a buried object under the ground to form sludgy portion, and an expansible material is injected to move the buried object. CONSTITUTION:A casing pipe 2 is penetrated in a vertically adjustable manner until the tip 2a of the pipe 2 reaches a region S where sludgy portion is to be formed. A feed pipe 3 is lowered from the pipe 2, and pressure water W is jetted through a pressure pump WP from a nozzle 4 into the region S to form sludgy portion. An expansible solidifying material is injected to the opposite side of the predetermined direction of correcting the moving of the buried object A under the ground. Whereupon, the buried object A is moved toward the sludgy portion by the expanding force of the material, and sludge is discharged from the space 5 between the inner wall 2b of the pipe 2 and the feed pipe 3 by means of the pressure being caused.
