The lower wall has a structure with a set of layers applied to each other in the direction of thickness, including one sealing membrane and one heat-insulating barrier located between sealing membrane and the bearing structure. The lower wall has sump structure (9) having rigid container (10, 11) containing sidewall (12). Container (10, 11) is located along a thickness of the sidewall, and sump structure (9) contains one fastener (15) intended for the attachment of rigid container (11) to bearing structure (1) at a point of attachment. One fastener (15) is made with the possibility of provision of a possibility of relative movement of sidewall (12) of container (11) relatively to bearing structure (1) in a transverse direction perpendicular to sidewall (12) at the point of attachment of container (11).

EFFECT: improvement of attachment between a sump structure and a bearing structure in order to increase a service life and increase the reliability.
