The cavities formed between the shaped sections receive concrete blocks and flexible joints. The metal skin has a peripheral rising portion along the walls of the enclosure and extending up to the maximum fluid level in the enclosure.Application to enclosures having to receive hydrocarbons or liquid sodium, e.g. on the site of a fast neutron nuclear reactor.Field of SearchWITH PROTECTIVE LIQUID SUPPLYOpen top, embedded container, tank, or reservoir Dissimilar material hoop tie Transversely layered Wall of contacting layers Disparate material lamina between layers Dissimilar material sheet-form facing Attached filament or mesh Stonelike load bearing-type component | |
