    • PROBLEM TO BE SOLVED: To provide a stack demolition method capable of easily peeling lining having a steel wire and improving the efficiency of peeling work.SOLUTION: The configuration of the stack demolition method related to this invention is the stack demolition method for demolishing a stack 100 for which asbestos-containing lining 104 is executed to the inner surface. The stack is cut roughly in the horizontal direction and turned to a cylindrical body 150, the cylindrical body is moved to the vicinity (a work bench 130a) of a disposal yard 130, and an outer wall 102 of the cylindrical body is cut in a window shape from the outer side while attaining the state that the upper end vicinity and lower end vicinity of the cylindrical body are annularly connected. The cylindrical body is moved into the disposal yard (a peeling chamber 134), negative pressure suction of air inside the disposal yard is executed, and by pushing a cut surface 150b to the inner side or outer side of the cylindrical body, the cut surface is hollowed out from the cylindrical body and turned to a block 152. The lining executed to the hollowed block and the cylindrical body from which the block is hollowed is peeled.
    • 要解决的问题:提供一种能够容易地剥离具有钢丝的衬里并提高剥离效率的层叠拆除方法。 解决方案:与本发明相关的堆垛拆除方法的结构是将用于其内含有石棉的内衬104执行的堆垛100拆除的堆垛拆除方法。 堆叠体大致沿水平方向切割并转向圆筒体150,圆筒体移动到处置场所130的附近(工作台面130a),圆筒体的外壁102被切割成 同时实现圆筒体的上端附近和下端附近环状连接的状态,从外侧观察窗形状。 圆筒体移动到处理场(剥离室134)中,执行处置场内的空气的负压抽吸,并且通过将切割面150b推到圆筒体的内侧或外侧,切割面 从圆柱体中挖出并转向块152.对中空块进行的衬里和块被中空的圆筒体剥离。 版权所有(C)2012,JPO&INPIT
