A fluid-tight tank is composed of a plurality of separate components. Each component is preferably formed from cement and provided with an interior region having a circular cross-section. Each component has a plurality of chase ways extending throughout its length. Post-tension cables are routed through these chase ways and are tightened so as to compress the components together so they act as one integral unit. Each component is has an annular flange-like protrusion and/or recess so that adjacent components can be aligned with one another while maintain...
A multi-component tank comprising: a first end component having a first end wall; a second end component having a second end wall; a plurality of intermediate components disposed between said first end component and said second end component to form a line of components that define one or more interior regions for storing fluids; and post-tensioning means for providing a compressive force to the line of components by applying a force to said first and second end components by stressing and elongating post-tension cables so that said force is distributed ...
