<p>A sealed protective container (1,2) for the underground installation of a cylindrical reservoir (11) containing gas under pressure, with the cylinder axis lying horizontally, comprising a housing shell (1,2) for the reservoir (11) with the formation of an interspace (53) between the shell and the reservoir, an upper hatch (26) for access to the interspace and means (8,9) of supporting the reservoir adapted to allow rotation of the reservoir (11) about the cylinder axis, so that the inspection of the reservoir lower surface can take place through the hatch as the reservoir is rotated. As a possible alternative, the shell is formed of two tightly coupled half-shells, an upper one and a lower one, and the inspection of the whole surface of the reservoir can take place by removing the upper half-shell. <MATH></p> |
