PROBLEM TO BE SOLVED: To provide a chimney washing demolition device washing the inside of a chimney and demolishing an internal cylinder in the demolition of the chimney having an internal-external double structure having an inner wall as a heat-resisting wall on the inside of an external cylinder. SOLUTION: The chimney washing demolition device 43 is hung down in the internal cylinder 13 disposed in upright by forming an opening 12 inside the external cylinder 11 in a freely vertically movable manner. The device 43 has an expansion mechanism 54 holding a position by pushing the inner wall surface of the chimney, the expansion mechanism 59 for crushing the internal cylinder gripping the edge section of the internal cylinder 13, the expansion mechanism 62 for an abutting against a lower section abutted against the inner wall surface of the internal cylinder 13 on the lower side by a fixed quantity from the edge section of the internal cylinder 13 and a washing nozzle 47 washing the chimney by water from the inside. The internal cylinder 13 is broken by the fixed quantity by shrinking the expansion mechanism 59 under the state in which the expansion mechanism 62 is extended. COPYRIGHT: (C)2005,JPO&NCIPI
