PURPOSE:To prevent the levitation of a depository body by the pressure of water by connecting the L-shaped flange of the upper half portion of the depository body to the anchors of the foundation through metals and couplers. CONSTITUTION:A semi-underground depository body 1 consists of the upper half portion having an L-shaped flange 12 and a flange 13. In constructing the depository, the body 1 is set in such a way that the lower half of the body 1 is positioned below the ground's surface GL and an opening 10 is connected to the floor FL, while a cement mortar foundation 9 on which the body 1 is to be set is formed, and the lower ends of anchors 5 are buried in the foundation 9. Nuts 7 on the upper ends of couplers 6 connected with the upper ends of the anchors 5 are clamped, and the flange 12 is pulled toward the foundation 9 through metal fixtures 4. The levitation of the body 1 by pressure of water can thus be prevented even when water flows into the surrounding of the body 1. |
