The bottom plate deformed as described above is deformed repeatedly so that when the water pressure increases, the raised part of the bottom plate is momentarily turned off to reach the concrete floor, and the water level decreases again when the water pressure decreases. As described above, when the bottom plate is repeatedly deformed, the stress caused by the deformation is variably generated in the welded portion of the bottom panel, and eventually, fatigue accumulates in the welded portion, causing a problem of rupture.
