Abstract
A pollutant storage system that provides substantial wall strength with greatly reduced concrete mass. Reinforced concrete panels precast with a pattern of surface cavities and supported by precast reinforced concrete A-frames enclose a paved floor area.
Claims8
A polygonal pollutant storage system comprising:
- (a) a paved floor;
- (b) a plurality of precast reinforced concrete wallpanels enclosing said floor, each precast panel having a pattern of surface cavities reducing its mass;
- (c) a plurality of precast A-frame supports installed exterior to and perpendicular to said wall panels for structural support whereby each of said panels angles so that the perimeter of the system is smaller at the floor level than at the top of the wall panels;
- and,
- (d) a trapezoidal panel at each corner having angled sidewalls to mate flushly with the inner surfaces of adjacent wall panels from said floor to the top of said wall panels with the whole of each sidewall surface of said trapezoidal panel bearing against said inner surfaces of adjacent wall panels, said inner surfaces being those surfaces facing the interior of said storage system.
