METHOD FOR TRANSFORMING AN EXISTING SINGLE-WALLED TANK INTO AN INTRINSICALLY SAFE DOUBLE-WALLED TANK

摘要

METHOD FOR TRANSFORMING AN EXISTING SINGLE-WALLED TANK INTO AN INTRINSICALLY SAFE DOUBLE-WALLED TANK, which, after cleaning the existing wall (1) and applying a reinforcing coating (2), provides for the construction of the interstitial chamber (3) by placing a permeable mesh (4), nozzles for extracting the air, a first flexible sealed bag (5), and creating a vacuum between said bag (5) and the existing wall (1); and, subsequently, the construction of the new wall (6), placing the fibre fabrics that will form the same, nuclear materials or helical pipes or both, for distributing resin by infusion, a second flexible bag (7), creating a vacuum between both bags (5,7) with the fibre fabrics and the distribution materials therebetween, and executing the infusion of resins until completely soaking the fabrics of the new wall (6).
