Abstract:
A land-based spill-containment tank for receiving spilled liquids, said tank being foldable for storage and being a spring-operated, pop-up device for liquid collection comprising:a base of flexible material;a wall integral with said base attached at the periphery thereof and arising therefrom;a pocket formed in said wall, said pocket having an inner facing of flexible material contiguous to and continuous with an outer facing of flexible material; and,a spring truss fitted within said pocket forming a wall erecting mechanism, said spring truss circumferentially disposed about said base adjacent the juncture of said wall and said base, said spring truss substantially vertically expandable within said pocket to erect the wall with sufficient tension to resist, when the spill-containment tank formed thereby is filled with spilled liquid, significant diminution of the wall height, said spring truss, upon erection of said wall and before filling with spilled liquids, provides a beam which is supportable at one portion thereof to cantilever the tank during positioning.
