Abstract (en)
[origin: EP0752555A1] An improved fluid-tight, openable, protective container (1, 2, 3, 4) for the underground installation of a tank of pressurized, liquefied gas (14) with the formation of an interspace (17) between the container and the tank housed therein, in which the container has a top (3) which has a hatch (4) and is fixed removably to a peripheral wall (1) and which forms, with a connecting collar (12) of the hatch (4), a semitoroidal housing for a sealing ring (13) for separating the interspace (17) from a space inside the hatch (4), the semitoroidal housing having an outer edge (18) for bearing on the tank (14) to ensure a predetermined compression of the seal (13), an opening of predetermined depth (H1) between an inner edge (20) of the housing and the tank (14), and differentiated sealing by the seal (13) under excess pressures according to whether these develop in the interspace (17) or in the space inside the hatch (4). The outer edge (18) has at least one radial channel which enables inspection probes to be introduced into the interspace from the hatch simply by the removal of the seal (13), without the need to remove the top (3). <IMAGE>
