WATERPROOF AND THERMALLY INSULATING TANK

摘要

Watertight and thermally insulating tank comprising a secondary insulation barrier (2), a corrugated secondary waterproofing membrane (3), a primary insulation barrier (4) and a corrugated primary waterproofing membrane (5), the corrugations primary (14) and the secondary corrugations (10) being superimposed in a thickness direction, the dimension in the thickness direction of the primary insulation barrier (4) being less than the dimension of the secondary corrugations (10) taken in said thickness direction so that the secondary corrugations (10) pass through passages (13) of the primary insulation barrier (4) and are partially housed in the primary corrugations (14), the tank further comprising a member primary reinforcement (20) inserted in the thickness direction between a secondary corrugation (10) and a primary corrugation (14) superimposed so as to reinforce said primary corrugation (14).
