CUTTING METHOD OF GROUND

PURPOSE:To cut the ground in any shape by boring in a required ground, driving a cutting anchor into the hole, cutting and traveling a wire of a wire saw to expand the wire and, at the same time, rotating the wire around the axial center of the hole. CONSTITUTION:A hole 7 is bored in a required grou...

Summary:PURPOSE:To cut the ground in any shape by boring in a required ground, driving a cutting anchor into the hole, cutting and traveling a wire of a wire saw to expand the wire and, at the same time, rotating the wire around the axial center of the hole. CONSTITUTION:A hole 7 is bored in a required ground by an excavator 6, and after a wire 11 of a wire saw 10 is wound around a pulley 4 of a cutting anchor 1, it is inserted into the hole 7 to drive the cutting anchor 1 in a hard ground 12. After that, a driving pulley 13a is rotated by a driving device 13, and a tension pulley 14 is widened and guided to expand the wire 11 in a required size with the pulley 4 as the center while cutting and traveling the wire 11. Then, the wire 11 is rotated around the axial center 7a of the hole 7, and the ground 5 is cut in any shape. Cutting is made in the shape of an approximate cone with the pulley 4 as the summit. According to the constitution, a construction period can be greatly reduced with a simple equipment.
