にある。In the conventional cutting methods (i) and (ii) described above, it is necessary to hang the wire saw Ws around the lateral or vertical direction of the portion of the structure to be cut. Therefore, many lateral holes are bored in the wall of the structure 6, and the wire saw Ws is passed through these holes, or the wire saw Ws is hung on a plurality of guide pulleys. There is a drawback that cannot be done. In the case of the structure 6 made of reinforced concrete, it is necessary to control the cutting amount according to the amount of the reinforcing bar, but there is a disadvantage that the cutting amount cannot be delicately controlled. Further, it is necessary to change the position of the guide pulley that guides the wire saw Ws according to the progress of cutting, and it takes a lot of time to replace the guide pulley. Further, since a large amount of cooling water is supplied to the cutting portion, a large amount of cooling water mixed with cutting chips is scattered and pollutes the surroundings. Therefore, this cutting method (i), (ii) is used for dismantling a concrete structure of a nuclear facility.
There is a big problem in adopting the method in terms of radiation exposure of workers, expansion of radiation pollution, and the like. Conventional cutting method (i
ii): Lifting the cutting device with the movable boom of the operating device, and inserting the pair of support arms attached to the connecting member into the pair of vertical holes formed in the concrete structure that is the cutting target. Then, the front end of the support arm is positioned by the positioning metal fitting provided in each vertical hole, and the weight of the weight holds the arm-like support, the connecting member, etc. at the predetermined position, and then the guide of each arm-like support is provided. Since the portion of the wire saw that runs at high speed between the pulleys is brought into contact with the concrete portion between the pair of vertical holes to push down the concrete in that portion, each vertical portion of the cutting target of each arm-like support is cut. Positioning with respect to the holes is troublesome, the cutting device is advanced toward the side surface of the concrete structure that is the object to be cut, and each of the arm-like supports is formed in a pair of lateral holes formed in the side surfaces of the structure. Insert it into its forward motion To contact the part of the high-speed wire saw between the guide pulleys at the end of the arm-shaped support with the concrete structure between the lateral holes in the concrete structure to push through the concrete in this part. There is a drawback that you cannot do. The problem to be solved by the present invention is to provide a cutting method and a cutting device using a wire saw that does not have the above-mentioned drawbacks of the conventional cutting methods (i) to (iii), in other words, a wire saw. The arm-shaped support with a guide pulley that guides the movement of the wire is easy to move with respect to the object to be cut, and the cutting amount can be controlled and remote operation can be performed. A wire saw with excellent safety and workability is used. It is to provide a cutting method and a cutting device.
