CONSTRUCTION METHOD OF FIXED-ROOF FLAT-BOTTOM CYLINDRICAL TANK
To provide a method for constructing a metal fixed-roof flat-bottom cylindrical tank with a concrete outer tub for tsunami countermeasures, in which the metal fixed-roof flat-bottom cylindrical tank is constructed by means of a form slide method capable of constructing a side wall of the concrete outer tub from the lower portion to the upper portion.SOLUTION: The method includes a main process in which steps (b) and (c) of lifting a fixed roof 6 together with a reinforcing structure 20 and raising an outer mold 3b1 by mold raising means 11, and steps (d) and (e) in which concrete is placed and solidified between a side plate 4b of an inner tank 4 and the outer mold 3b1 while reinforcing the side plate 4b of the inner tank 4 with the fixed roof 6 and the reinforcing structure 20 are sequentially repeated plural times to construct a side wall 3b of an outer tub 3 from the lower side to the upper side, and a post-process for fixing the fixed roof 6 to the top of the side plate 4b of the inner tank 4.SELECTED DRAWING: Figure 4
【課題】 津波対策等の目的でコンクリート製の外槽を備えた金属製の固定屋根式平底円筒形タンクを構築するに当たって、前記コンクリート製の外槽の側壁を下方から上方へ構築することが可能な型枠スライド工法による固定屋根式平底円筒形タンクの施工方法を提供することにある。【解決手段】 補強構造２０と共に固定屋根６を吊り上げ、型枠上昇手段１１で外側型枠３ｂ１を上昇させる工程（ｂ）、（ｃ）と、内槽４の側板４ｂを固定屋根６及び補強構造２０とで補強しつつ、内槽４の側板４ｂと外側型枠３ｂ１の間にコンクリートを打設して凝固させる工程（ｄ）、（ｅ）とを複数回順次繰り返して、外槽３の側壁３ｂを下方から上方へ構築する工程とで構成する本工程と、固定屋根６を内槽４の側板４ｂの頂部に固定する後工程とで構成することを特徴とする。【選択図】 図４
