SYSTEM AND METHOD FOR COMPRESSED GAS ENERGY STORAGE AND RESTITUTION HAVING A PRECONTRATED CONCRETE MIXED LAYER

摘要

The invention relates to a tank for storing a fluid under pressure such as compressed air. In particular, the reservoir is in the form of at least one tube formed of an arrangement of concentric layers (C1, C2, C3, C4), this arrangement comprising, going from the inside to the outside of the tube, an inner layer formed of concrete (C1), a layer (C2) formed of steel of thickness E, at least one layer (C3) formed by a winding of wires (C3 ") made of steel on a concrete sub-layer ( C3 '), and an outer layer (C4) for protecting said yarns against physical and / or chemical damage, and wherein the yarns are circumferentially tension preloaded, at least the thickness E and / or the prestressing being dimensioned so as to withstand said pressure, particularly for the storage and return of energy by compressed air.
