PROBLEM TO BE SOLVED: To provide a tank demolition method for demolishing a tank without using a large-scale facility.SOLUTION: A tank demolition method is for demolishing a tank having a bottom plate and a side wall extending upward from the bottom plate. A first region and a second region that are laid out alternately in a circumferential direction are set at a bottom edge part of the side wall. A deforming guide part is installed between a foundation part including the bottom plate and the first region, the deforming guide part having a guiding surface for guiding the first region in an out-of-plane direction of a wall surface of the side wall and deforming the first region, when the side wall has been lowered. The demolition method includes a slit formation step for forming a slit in the side wall along a boundary line between the first region and the second region, a bottom edge part removal step for removing the second region at the bottom edge part, and a lowering step for lowering the side wall while the foundation part and the side wall are separated. In the lowering step, the first region of the lowered side wall is guided by the guiding surface of the deforming guide part and is deformed.SELECTED DRAWING: Figure 5
【課題】大掛かりな装置を用いることなくタンクを解体することが可能なタンク解体方法を提供する。【解決手段】底板と底板から上方に延在する側壁とを備えるタンクを解体するタンク解体方法であって、側壁の下端部には、周方向に交互に配置される第１領域と第２領域とが設定され、底板を含む基礎部と第１領域との間には、側壁が降下したときに、第１領域を側壁における壁面の面外方向に案内して変形させる案内面を有する変形ガイド部が設置され、第１領域と第２領域との境界線に沿って側壁に切込みを形成する切込み形成工程と、下端部における第２領域を除去する下端部除去工程と、基礎部と側壁とが切り離された状態において、側壁を降下させる降下工程と、を備え、降下工程では、降下する側壁の第１領域が変形ガイド部の案内面に案内されて変形する。【選択図】図５
