Summary: | PURPOSE:To reduce a construction period by constructing cutting wires between structural boards provided to both sides of a tunnel scheduled to excavate so that they are capable of reciprocating, traveling them to cut and move in any direction, and cutting and working ground in the required shape of a tunnel. CONSTITUTION:Structural boards 2 and 2 having guide sections 4 for moving traveling devices 1a of a wire saw 1 in the direction of up and down are erected to both sides of a tunnel of the ground 5 scheduled to excavate, and cutting wires 1b of the wire saw 1 are constructed between the structural boards so that they are capable of reciprocation. After that, the cutting wires 1b are traveled by driving of a motor 3, and the traveling devices 1a are lowered along the guide sections 4 while cutting the ground 5 from above. The traveling devices 1a are rotated to move the structural boards 2 and 2 in right and left directions freely, and the ground 5 is cut and worked in the required shape 6 of a tunnel. According to the constitution, a section of the tunnel is freely formed, and construction period can be greatly reduced. |
