LOW-TEMPERATURE LIQUEFIED GAS ABOVEGROUND TANK
PROBLEM TO BE SOLVED: To increase an effective liquid storage amount of a low-temperature liquefied gas aboveground tank 1.SOLUTION: An aboveground tank 1 has a double structure of an outer tank 2 and an inner tank 6. The outer tank 2 is constituted by an RC bottom slab 3, a PC side wall 4, and a steel outer tank roof 5. The inner tank 6 is constituted by a steel inner tank bottom plate 7, a steel inner tank side wall 8, and a steel inner tank roof 9. The inner tank bottom plate 7 is sloped downward from a peripheral end on the inner tank side wall 8 side to an arrangement position of a delivery pipe 15 (submerged pump 16). At the same time, an installation height of the submerged pump 16 becomes low. The RC bottom slab 3 and a bottom heat insulation material 11 have the same slope shape, and are formed to have the equal thickness.SELECTED DRAWING: Figure 1
【課題】 低温液化ガス地上タンク１の有効貯液量を増大させる。【解決手段】 地上タンク１は、外槽タンク２と内槽タンク６との二重構造である。外槽タンク２は、ＲＣ底版３と、ＰＣ側壁４と、鋼製外槽屋根５とからなる。内槽タンク６は、鋼製内槽底板７と、鋼製内槽側壁８と、鋼製内槽屋根９とからなる。ここにおいて、内槽底板７は、内槽側壁８側の周縁部から、払出し配管１５（サブマージドポンプ１６）の配置箇所に向かって、下り勾配になっている。同時にサブマージドポンプ１６の設置高さも低くなる。ＲＣ底版３及び底部断熱材１１は同勾配形状を有し、それぞれ等厚に形成される。【選択図】 図１
