PROBLEM TO BE SOLVED: To prevent a damage to a storage complex even when a relatively large partial pressure in a horizontal direction of a soil pressure is exerted on an outer peripheral surface of the storage complex, by receiving the partial pressure with a structurally solid outer peripheral wall.SOLUTION: A partition plate 12 of a storage complex 11 filled inside a storage tank 10 is formed as a square plate having at least one tubular rib protruded from a bottom surface and a top surface, and a tubular first spacer 21 is connected by fitting on the tubular rib of the partition plate. A plurality of horizontally connected bodies 41 to 44 are installed, the horizontally connected body being configured by lining up a plurality of the partition plates on the same horizontal plane and connecting between the partition plates. A first outer layer part 51 is formed at least on an outermost side of a storage tank, the first outer layer part being configured by alternately placing the partition plate and the first spacer in a vertical direction. Furthermore, an outer peripheral wall 15 is formed that surrounds an outer peripheral surface of the first outer layer part, by engaging each of a plurality of wall members 13 of a same shape to the partition plate and the first spacer that constitute the first outer layer part, and connecting the wall members to each other.SELECTED DRAWING: Figure 1 |
