Abstract
PURPOSE:To raise the bearing property of a hardened column by a method in which a flexible cylinder whose tip end is closed is inserted into a pit in the ground and a hydraulic slurry is packed under a higher pressure than the horizontal yield value of the ground into the cylinder. CONSTITUTION:A pit 4 of a smaller diameter than a given diameter of a hardened column is excavated in the ground, and a flexible cylinder 1 of a larger diameter than the given diameter is inserted into the pit. A packer 6 and a packer holder 7 are set in such a way as to close the upper end 8 of the cylinder and a hydraulic slurry 3 is packed into the cylinder under a pressure above the horizontal yield value of the surrounding ground. A hardened column having high adhesion to the surrounding ground and excellent bearing property can thus be constructed.
