<p>PROBLEM TO BE SOLVED: To provide a fireproof coating layer dismantling method capable of efficiently dismantling a fireproof coating layer inside chimney by allowing smooth replacement of a dismantling device of a different specification, with no use of a large crane for lifting.SOLUTION: By using a wire member 15 that is lifted down into the inside of a chimney 10 from a ground through a bending sheave 14 installed at an upper end part of a chimney body 11, through driving and controlling of a winding device 19 installed on the ground, dismantling devices 20a, 20b are lifted up/down inside the chimney 10, for dismantling of a fireproof coating layer 13. After the fireproof coating layer 13 in a predetermined height region is dismantled by the dismantling devices 20a, 20b, the dismantling devices 20a, 20b are lifted down to a bottom part 11a of the chimney body 11, and carried out through a carrying in/out opening part 16. Then, they are replaced with fireproof brick dismantling devices 20b, 20c of different specification which are carried in, and the replaced fireproof brick dismantling devices 20b, 20c are lifted up, for dismantling the fireproof coating layer 13 in a different height region.</p> |
