<p>A method for storing fluid underground at maximum pressure p, comprising the steps of digging, at a depth at which the lithostatic pressure generated by the weight of the abovejacent soil formations is at least p, an underground cavity in which is made a tight deformable casing anchored to the cavity wall at some places only, while it can freely expand or contract in every direction between said anchoring places, then of injecting pressurized fluid into said casing in order that the latter be fully applied against the cavity wall, the possible movements of which said casing subsequently follows by gliding, the pressure of said fluid being, at every moment, counterbalanced by the lithostatic pressure of the cavity walls transmitted to said fluid by the thus expanded casing.</p> |
