摘要

PROBLEM TO BE SOLVED: To provide a wire holder for a wire saw capable of easily cutting an existing pile embedded in the ground at a portion lower than that of the ground surface, a wire for the wire saw, and a cutting removal system and method for an existing pile. SOLUTION: The wire holder comprises a circular frame 11 allowing a substance 4 to be cut (an existing pile) to be inserted in the inside, a holder member 12 fitted to the frame 11 and capable of holding the middle of a wire 2 for a circular wire saw used for cutting the substance 4 in a state along the inner periphery of the frame 11, and sieves 13-16 fitted to the frame 11 turning the wire 2 from the direction along the inner periphery of the frame 11 to the direction crossing at right angles with the frame 11. The holding member 12 is so constituted as to be cut off by the wire 2 when the wire 2 for the wire saw travels. COPYRIGHT: (C)2004,JPO
