CONSTRUCTION METHOD OF PC/METAL DOUBLE-SHELL TANK
PROBLEM TO BE SOLVED: To perform material throw-in hole block construction in a short period of time by forming a material throw-in hole into an extremely-small hole when constructing an inner tank by withdrawing a steel plate having a flat plate shape or a substantially-circular shape in a cross section constructing an inner tank sidewall from the material throw-in hole which is formed at an outer tank sidewall, in a construction method of a PC/metal double-shell tank having a metal cylinder shell in the outer tank sidewall having a prestressed concrete structure.SOLUTION: A material throw-in hole 10 is opened by a width amount having a margin at a camber of a steel plate toward a tangential direction of a sidewall steel plate 4 (including scheduled construction) of an inner tank 2 in a cross section view by being formed into a parallelogram in the cross section view, and a steel plate 4a is transported through the opening of the material throw-in hole 10, and moved to a prescribed position of the inner tank 2 of a metal cylinder shell, thus constructing the inner tank 2.SELECTED DRAWING: Figure 1
【課題】プレストレストコンクリート構造の外槽側壁の内部に金属円筒殻の内槽を有するＰＣ・金属二重殻タンクの施工法であって、内槽側壁を構成する断面が平板ないし略円弧状の鋼板を外槽側壁に形成する材料投入孔から取り入れて内槽を構築する場合に、材料投入孔を極力小さなものですむようにして、材料投入孔閉塞工事を短時間で行うことが可能となる。【解決手段】材料投入孔１０は横断面視において平行四辺形となることで、横断面視において内槽２の側壁鋼板４（構築予定を含む）の接線方向に向けて、鋼板の矢高に余裕を持たせた幅分開口させ、前記鋼板４ａはこの材料投入孔１０の開口を通して搬入し、金属円筒殻の内槽２の所定位置に移動して内槽２を構築する。【選択図】 図１
