Patent attributes
A modular system for constructing liquid storage tanks, comprising prefabricated reinforced concrete modular elements designed and adapted to be coupled together to form the tank walls and having means for engaging the bottom slab or foundation. Optionally, the system further comprises elements which mate with the tank wall elements in order to build a covered tank. In one embodiment of the system, the modular wall elements include a prestressing wire or strand embedded in its structure and to which a tensile force is applied to produce a compressive stress in the side of the wall element that is contact with the liquid stored in the tank. Optionally, the constructing system comprises elements to form divisions or cells inside the storage tank.
