[Detailed Description of the Invention] Conventionally, when demolishing a reinforced concrete structure, the concrete structure is either attacked with a solid iron block and demolished by impact, or a cutter blade is used to cut the concrete structure and demolish it. These methods are widely used, but these conventional methods (reinforced concrete that has been contaminated by radioactivity in a nuclear reactor)
'? The present invention solves these problems and efficiently dismantles cylindrical reinforced concrete structures whose surfaces are radioactive or contaminated with radioactive materials. It was often proposed to safely cut and disassemble from the inner surface, and the lower end surface of the circular main body has jacks for controlling the posture and supporting rotational reaction force vertically, which expands and contracts in the uniaxial direction G. This is a reinforced concrete cutting machine characterized by having a canter disc that rotates around the central axis of the main body, and a mantissa rotating cutting blade on the lower end surface of the cutter disc. Since the cutting machine according to the present invention is configured as described above, the circular main body is placed in the center of the suspended reinforced concrete structure with only f#, ' L, inside the penal letter. By rotating the cutter disk around the nozzle b axis and rotating the mantissa rotation t sub-edge arranged on the cutter disk, the inner circumferential t-plane of the hollow part of the structure described in iii is cut by the rotating cutting blade. A cutter disc equipped with a rotary cutting blade rotates around the central axis of the cylindrical main body, and as a result, the rotary cutting blade comes into contact with a predetermined cutting surface. So, there is no cutting residue, and you can cut it into 1,000 ryo pieces.
