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 (C1, C2, C3, C4). This arrangement comprises, working from the inside toward the outside of the tube, an internal layer (C1) formed of concrete, a layer (C2) formed of steel of thickness E, at least one layer (C3) formed by a winding of steel wires (C3″) on a sublayer (C3′) of concrete, and an external layer (C4) 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.
A reservoir for storing a pressurized fluid including at least one tube formed as concentric layers, the concentric layers consisting of from the inside toward outside of the tube, an internal layer formed from concrete, a layer formed from steel, at least one layer of wound steel wires disposed on a continuous sublayer formed from concrete, and an external layer protecting the steel wires against at least one of physical and chemical damage, and wherein the wires are circumferentially prestressed, and wherein thickness of the layer formed of steel and the at least one layer of steel wires wound on a sublayer withstand pressure of the pressurized fluid in excess of 100 bar.
