A fluid holding tank and method of assembly thereof

摘要

A tank for fluids has an inner tank lining for contact with a fluid to be stored and an outer boundary wall assembly including a plurality of interconnected members. Panels are disposed between the wall assembly and the lining with the panels being free to move relative to each other. The boundary wall assembly is arranged to increase in perimeter length in response to fluid pressure increasing within the tank in order to cope with the increased pressure.
