DEMOLITION METHOD FOR STEEL TOWER SUPPORTED STACK
To provide a demolition method for a steel tower supported stack capable of easily and surely demolishing a steel tower supported stack without using a large crane.SOLUTION: After removing a stack shell, a temporary support constructed by the removed stack shell is lifted up to the upper part of the steel tower by a first jack, and the upper steel tower around the temporary support is dismantled and removed. After that, the following operations are repeatedly performed: the temporary support is suspended to the ground by the first jack; the first jack is replaced with the next stage; the temporary support is lifted up to the next stage of the steel tower by a first jack; and the next stage steel tower around the temporary support is demolished and removed.SELECTED DRAWING: Figure 1
【課題】大型クレーンを使用することなく、鉄塔支持型煙突を容易に安全かつ確実に解体することができる、鉄塔支持型煙突の解体方法を提供する。【解決手段】筒身を撤去後、撤去した筒身により構築した仮設支柱を、鉄塔の上部まで第１ジャッキにより吊り上げ、仮設支柱の周囲の上段鉄塔を解体・撤去し、この後、第１ジャッキにより仮設支柱を地上まで吊り下ろし、第１ジャッキを次段に据え替えた後、第１ジャッキにより仮設支柱を鉄塔の次段まで吊り上げ、仮設支柱の周囲の次段鉄塔を解体・撤去する操作を繰り返し行う。【選択図】図１
