PURPOSE: To easily and exactly corect by moving of a buried object under the ground by a method in which a pressure fluid is jetted in the predetermined direction of moving the buried object under the ground to form an inductive space, and an expandible material is injected to move the buried object.

CONSTITUTION: A casting pipe 2 is penetrated in a vertically adjustable manner until the tip 2a of the pipe 2 reaches a region S where an inductive space is to be formed. A feed pipe 3 is lowered from the pipe 2, and a pressure fluid W, e.g., water or air, is jetted through a pressure pump WP from a nozzle 4 into the region S to form the inductive space by excavating the soil of the region S. The excavated soil is discharged with the pressure fluid from the space 5 between the inner wall 2b of the pipe 2 and the feed pipe 3. An expandible solidifying material is then injected to the opposite side of the predetermined direction of correcting the moving of the buried object A under the ground, and the buried object A is moved toward the inductive space side by the expansion force of the material.
