<p>PURPOSE:To prevent breakage eliminating changes of original shapes at the bottom corners due to cooling contraction and thermal expansion predicated on rising the side bulkheads of the outer reservoir on the surface owing to congealed soil and inlet and outlet of stored liquid in such a way that the underneath of the inner reservoir is reinforced and anchored at the bottom part of the outer reservoir. CONSTITUTION:Since the inner reservoir 3 is solidified at anchors 8 with use of an anchor bar 7 at the bottom of the outer reservoir 1, even if soil around the outside of the tank is congealed and the side bulkheads of the outer reservoir 1 may be broken separatedly from the bottom part and pushed up in the arrow X direction, it will be without fear of being drawn up by friction, in consequence, because the bottom corners keep the original form, there is no breakage. Secondly, since the bottom corners of the inner reservoir 3 are tightly fixed by the anchors 8, even if the inner reservoir 3 reiterates cooling contraction and thermal expansion by routine inlet and outlet of stored liquid, because the propinquity to the bottom corners does not crawl, there will be no cases of breaking and yielding creeps by deformation due to the changes.</p> |
