Abstract
The invention relates to a sealed tank (1) comprising a first and a second adjacent wall (3; 7; 8); each of the first and second walls (3; 7; 8) comprising a corrugated sealing membrane (50; 52) meeting at a junction zone (60). According to the invention, the junction zone is adapted to allow: the connection of a first corrugation (56b1) of a third series of corrugations (56b) of the second membrane (52) to a first corrugation (56a1) of a first series of corrugations (56a) of the first membrane (50); the connection of a second corrugation (56b2) of the third series of corrugations (56b) of the second membrane (52) to a second corrugation (58a2) of a second series of corrugations (58a) of the first membrane (50); and the redirection of a third corrugation (56b3) of the third series of corrugations (56b) of the second membrane (52) to the first sealing membrane (50). (Figure 3 [Fig. 3])
