DISMANTLING METHOD OF FLOATING ROOF TYPE CIRCULAR TANK
To provide a dismantling method of a floating roof type circular tank, in which the floating roof type circular tank can be dismantled easily and in a short period of time without using a large crane.SOLUTION: The method comprises a step in which a plurality of openings 5 are provided in a side wall 3, the floating roof is removed, a reinforcing member 6 is attached to the inside of a side wall portion 7 to be removed, and a rail 8 is mounted on a bottom plate 2 between a center of a tank 1 and the opening 5. The lower part of the reinforcing member 6 and the rail 8 are connected via a fixed hinge 9, a carriage 10 and side wall pull-down means 11 are installed on the rail 8, and a carriage 10 and the reinforcing member 6 are connected by the side wall supporting member 11 via a movable hinge 16, the side wall portion 7 is cut and separated from the side wall 3, and the carriage 10 is moved along the rail 8 toward the center of the tank 1 by the side wall pulling-down means 11 and the side wall portion 7 is pulled down into the tank 1 with the fixed hinge 9 of the reinforcing member 6 as a supporting point, the side wall portion 7 is cut, and the cut side wall piece is carried out of the tank and removed.SELECTED DRAWING: Figure 8
【課題】浮き屋根式円形タンクを大型クレーンを使用することなく容易かつ短期間に解体することができる、浮き屋根式円形タンクの解体方法を提供する。【解決手段】側壁３に複数個の開口５を設け、浮き屋根を撤去し、撤去する側壁部分７の内側に補強材６を取り付け、タンク１の中心部と開口５との間の底板２上にレール８を設置し、補強材６の下部とレール８とを固定ヒンジ９を介して連結し、レール８に台車１０と側壁引倒し手段１１とを設置し、台車１０と補強材６とを側壁支持材１１により可動ヒンジ１６を介して連結し、側壁部分７を切断して、側壁３から切り離し、側壁引倒し手段１１により、台車１０をレール８に沿ってタンク１の中心方向に移動させて、側壁部分７を、補強材６の固定ヒンジ９を支点としてタンク１内に引き倒し、側壁部分７を切断し、切断した側壁片をタンク外に搬出して、撤去する工程を備えている。【選択図】図８
