FIELD: manufacturing technology.
SUBSTANCE: invention relates to tight and heat-insulated reservoir containing sealed membrane, heat-insulating barrier and reinforcing part (15) for strengthening of sealing membrane to action of liquid pressure contained in reservoir. Heat-insulating barrier comprises groove (83, 84) parallel to longitudinal direction of corrugation, and reinforcing part (15) comprises retaining rib inserted into groove, retaining rib forms end ledge (22), passing in groove behind longitudinal end of housing in longitudinal direction of corrugation. Locking element (24) attached to heat-insulating barrier stops retaining part in longitudinal direction of corrugation in the first direction and interacts with end ledge (22) to lock reinforcing part in direction from support surface.
EFFECT: providing simplicity and reliability of fastening of reinforcing parts during assembly of reservoir wall.
