The invention provides a method of cutting and diassembling a cylindrical structure. According to the invention, the structure is cut into small blocks by using an abrasive jet operated by remote control and those small blocks are conveyed to the outside. To cut the structure into the small blocks, the structure is sequentially cut in the axial line direction and circumferential direction from the upper portion to the lower portion, or the structure is first cut into a ring-shaped primary block of a predetermined height and this primary block is conveyed to a predetermined location and is further cut into small secondary blocks, or the structure is first cut into a primary block having a predetermined arc length in the axial direction and this primary block is conveyed to a predetermined location and is further cut into small secondary blocks.

DETAILED DESCRIPTION It is therefore, an object of the present invention to provide a method of cutting and disassembling a structure whereby a cylindrical structure made of reinforced concrete is cut into blocks and removed.
According to the invention, there is provided a method of cutting and disassembling a cylindrical structure from the side of the outer wall whereby the structure is sequentially cut from the upper portion to the lower portion in both the axial line direction and in the circumferential direction by using an abrasive jet operated by the remote control and then further cut into small blocks having predetermined dimensions, and subsequently the cut small blocks are carried to the outside.
According to the invention, there is provided a method of cutting and disassembling a cylindrical structure from the side of the inner wall whereby the structure is cut from the upper portion into ring-shaped primary blocks each having a predetermined height by using the abrasive jet by the remove control, the cut ring-shaped primary blocks are lifted up and carried out to a predetermined location, and each of the ring-shaped primary blocks carried to the predetermined location is then cut into small secondary blocks having predetermined dimensions in the circumferential direction.
Further, according to the invention, there is provided a method of cutting and disassembling a cylindrical structure from the side of the outer wall whereby the structure is cut into primary blocks each having a predetermined arc length in the axial direction by using the abrasive jet operated by the remote control, the cut primary blocks are lifted up and carried out to a predetermined location, and each of the primary block carried to the predetermined location is then cut into small secondary blocks having predetermined dimensions.
According to the invention, when disassembling a radiation shielding wall (RSW) in e.
g.
, a BRW blocks having predetermined dimensions from the upper portion to the lower portion by remote control, the cut small blocks are carried to the outside and the RSW can be safely disassembled and removed without creating a danger for the workers
