DISMANTLING METHOD OF TANK
To dismantle a tank without using a sealant, while suppressing scattering of a contaminant.SOLUTION: A dismantling method of a tank 10 in which a contaminant is attached to an inner wall and which includes a bottom, a roof 12 and a peripheral wall part 13 connecting the bottom to the roof 12, comprises the steps of: dividing the peripheral wall part 13 into multiple block pieces 130 at multiple positions of the peripheral wall part 13 by making cuts partially in the vertical direction and the circumferential direction; removing the roof 12 by cutting and separating; cutting residual parts 42 around the block pieces 130 of the peripheral wall part 13 after removing the roof 12 and removing the separated block pieces 130 for all of the block pieces 130 of the peripheral wall part 13; and removing the bottom remaining after removing the roof 12 and the peripheral wall part 13.SELECTED DRAWING: Figure 4
【課題】封止剤を用いることなく、汚染物質の飛散を抑制しつつ、タンクを解体する。【解決手段】底部と、屋根部12と、底部と屋根部12とをつなぐ周壁部13とを備え、内壁に汚染物質が付着したタンク10の解体方法は、周壁部13の複数箇所において、鉛直方向および周方向に部分的に切り込みを入れることによって、周壁部13を複数のブロック片130に区分けする工程と、屋根部12を切り離して撤去する工程と、屋根部12の撤去後に、周壁部13のブロック片130の周囲の切り残し部42を切断し、切り離したブロック片130を撤去する工程を、周壁部13の全てのブロック片130に対して行う工程と、屋根部12と周壁部13が撤去された後に残った底部を撤去する工程と、を備える。【選択図】図4
