Method of forming a fluid retaining wall

Abstract

Abstract A COMPOSITE WALL OF REINFORCED SYNTHETIC RESIN, FOR RETAINING BOTH GASES AND LIQUIDS, THAT IS PARTICULARLY ADAPTED FOR UNDERGROUND USE IN GASOLINE STORGAE TANKS, WHICH ARE RESISTANT TO EXTERNAL COMPRESSION FORCES; SUCH AS, WATER FLOODED EARTH. THE WALL IS CHARACTERIZED BY A VERY HIGH STIFFNESS FACTOR, PRODUCED BY A COMBINATION OF SPACED RIBS OF FILAMENT WOUND MATERIAL AND THAT ARE HOLLOW, RETAINED ON TOP OF A CHOPPED STRAN-RESIN WALL, WHERE THE CHOPPED STRAND BRIDGES THE SPACES BETWEEN THE RIBS. A PROCESS INVOLVING THE STEPS OF FORMING A TANK END CAP ON A MANDREL AND THEREAFTER SUPPORTING THE END CAP IN SPACE AND LAYING UP A RESIN-RICH WALL LAYER OF CHOPPED STRAND AND RESIN IN JOINED RELATION TO THE END CAP, AND CURING THE WALL PARTIALLY; THEN FORMING OVER THE OUTER SURFACE OF THE WALL A HOLLOW SHELL STRUCTURE WHICH COMPRISES A COMBINATION OF WOVEN ROVING AND FILAMENT WOUND LAYERS SUPERIMPOSED AND SATURATED WITH WET RESIN. THEN COMPLETELY CURING THE COMPOSITE WALL TO PRODUCE A MONOLITHIC STRUCTURE.
