Method of cutting and disassembling cylindrical structure

摘要

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.
