METHOD FOR MANUFACTURING A SEALED, THERMALLY INSULATING TANK-WALL ELEMENT

摘要

The invention relates to a method for manufacturing a wall element (2b) intended for the construction of a sealed, thermally insulating tank for storing a fluid, said wall element (2b) including, in the thickness direction, from the outside towards the inside, a concrete bearing structure, a secondary sealed barrier (11) including a metal sheet (14), and a thermally insulating barrier (12); the method including an operation of anchoring the thermally insulating barrier (12) to the metal sheet (14) and an operation of forming the bearing structure (10) including the following steps: forming a formwork compartment (18), defined on the inside by the metal sheet (14) of the secondary sealed barrier (11) and on the outside by a removable formwork element (17); pouring concrete into the formwork compartment (18) so as to form the concrete bearing structure; and removing the removable formwork element (17) after the concrete has dried. The invention also relates to a method for manufacturing a tank, a wall element and a sealed, thermally insulating tank for storing a fluid.
