FIREPROOF COATING LAYER DISMANTLING METHOD INSIDE CHIMNEY
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.
【課題】大型の吊り上げ用の重機を用いることなく、規格の異なる解体装置の交換をスムーズに行えるようにして、煙突内部の耐火被覆層を、効率良く解体できる耐火被覆層解体方法を提供する。【解決手段】煙突本体１１の上端部に設置された屈曲シーブ１４を介して地上から煙突１０の内部に吊り降ろされたワイヤー部材１５を用いて、地上に設置された巻き上げ装置１９の駆動及び制御によって、解体装置２０ａ，２０ｂを煙突１０の内部で昇降させて、耐火被覆層１３の解体を行なう。解体装置２０ａ，２０ｂによって所定の高さ領域の耐火被覆層１３を解体した後に、解体装置２０ａ，２０ｂを、煙突本体１１の底部１１ａまで吊り降して、搬入搬出口部１６を介して搬出すると共に、搬入された規格の異なる耐火レンガ解体装置２０ｂ，２０ｃと交換し、交換した耐火レンガ解体装置２０ｂ，２０ｃを吊り上げて、異なる高さ領域の耐火被覆層１３を解体する。【選択図】図１
