Document Type and Number:
Japanese Patent JP3050523
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device for sufficiently removing a rotational reaction force even through the ground is weak.
SOLUTION: Reaction force removing members 64, 66 are coupled to opposite sides of a tubing device for pushing and rotating a casing tube so as to excavate a pile hole, through the intermediary of coupling frames 60, 62. The reaction force removing members 64, 66 are formed therein with guide parts 74, 76 for pile members 80, 82 to be inserted in a penetration hole 78 formed in substantially vertical direction and having a rectangular shape. The pile members 80, 82 are made of H-shape steel bars. Further, he pile members 80, 82 are driven into the ground so as to remove reaction force.
