Abstract
The invention is a reservoir for the storage of a pressurized fluid such as compressed air notably to the storage and recovery of energy using compressed air. In particular, the reservoir comprises at least one tube formed of an arrangement of concentric layers (C, C, C, C). This arrangement comprises, working from the inside toward the outside of the tube, an internal layer (C) formed of concrete, a layer (C) formed of steel of thickness E, at least one layer (C) formed by a winding of steel wires (C″) on a sublayer (C') of concrete, and an external layer (C) which protects the wires against at least one of physical and chemical damage, and in which the wires are subjected to circumferential (hoop) tensile prestress with at least one of the thickness E and the prestress being rated to withstand the pressure of pressurized fluid.
