Short description │
Supported Tank 2,000 m³ Cascavel
The tank is a monolithic structure in reinforced concrete, supported directly on the ground, for the
storage of treated water. Its capacity is 2,000 m³. As the water is treated with chlorine, the internal
environment of the tank is extremely aggressive due to the presence of chlorine gas in the air cushion
between the water surface and the lower face of the tank lid. Due to the presence of chlorine gas, a flat
slab with capitals was chosen as the tank lid to avoid the formation of a gas retention chamber under
the lid, wit the enhancement of the aggressive effect on the structure. Another design challenge was to
adapt the tank to the ground conditions to obtain a more economical solution in the direct foundation
(raft), within the limits of the admissible soil tension. In association with a team of geotechnical
professionals, the solution found was to replace and improve the soil layers to obtain the admissible
tension from the tank model within the economic viability of its execution.
