DEMOLITION METHOD FOR STEEL TOWER- SUPPORTED CHIMNEY AND DEMOLISHING DEVICE FOR STEEL TOWER-SUPPORTED CHIMNEY
To provide a safer demolition method for steel tower-supported chimney.SOLUTION: The demolition method is provided that includes the steps of: installing, inside a chimney, a lifting and lowering device having an upper platform; lifting and lowering the lifting and lowering device to a predetermined position, then cutting the chimney at a first chimney position and removing the cut first chimney part; installing a first unit having three or more expansion members on the upper platform of the lifting and lowering device, wherein each expansion member is expandable so as to project substantially horizontally from the steel tower; expanding each expansion member of the first unit to thereby project each expansion member substantially horizontally from the steel tower; installing a first scaffold on the expansion member in such a way that the first scaffold surrounds the steel tower while supported by the expansion member; cutting the steel tower at the first steel tower cutting position and removing the cut first steel tower portion; and removing the first scaffold and the first unit.SELECTED DRAWING: Figure 10
【課題】より安全な鉄塔支持型煙突の解体方法。【解決手段】煙突の内部に、上部台を有する昇降装置を設置する工程、前記昇降装置を所定の位置まで昇降させた後、前記煙突を第１の煙突位置で切断し、切断された第１の煙突部分を除去する工程、前記昇降装置の上部台の上に、３つ以上の拡張部材を有する第１のユニットを設置する工程であって、各拡張部材は、鉄塔から略水平に突出するように拡張可能である、工程、前記第１のユニットの各拡張部材を拡張して、各拡張部材を前記鉄塔から略水平に突出させる工程、各拡張部材の上に、該拡張部材に支持された状態で前記鉄塔を取り囲むようにして、第１の足場を設置する工程、前記鉄塔を第１の鉄塔切断位置で切断し、切断された第１の鉄塔部分を除去する工程、ならびに前記第１の足場および前記第１のユニットを取り外す工程、を有する解体方法。【選択図】図１０
