  • stresses are the cause of numerous damage problems to tank walls.
  • the sealing membrane is not stressed uniformly.
  • the thermally insulating barrier is discontinuous, that is to say that it is made up for example of heat-insulating elements juxtaposed with each other and each supporting a plurality of flat zones of the membrane.
  • waterproofing its behavior is not homogeneous when the waterproofing membrane deforms under the effect of thermal and mechanical stresses, indicated previously.
  • hydrodynamic pressures due to the “sloshing” phenomenon are exerted locally in certain flat areas of the waterproofing membrane and are only taken up by the heat-insulating element(s) which support said flat areas.
  • An idea behind the invention is to solve the aforementioned problems.
  • Another idea underlying the invention is to propose a wall for a waterproof and thermally insulating tank comprising supporting elements capable of resisting the forces exerted transversely to the direction of thickness of the wall.
  • the invention provides a wall for a sealed and thermally insulating tank for storing a liquefied gas, the wall comprising successively, in a direction of thickness of the wall, a thermally insulating barrier intended to be anchored , directly or indirectly, to a supporting structure and a waterproofing membrane which rests against the thermally insulating barrier, the thermally insulating barrier comprising: - at least one support element and - a modular structure located between the at least one support element and the sealing membrane, the modular structure being fixed against the at least one support element, the sealing membrane resting against the modular structure and being fixed to said modular structure, the modular structure comprising at least a first plate and a second plate, the sealing membrane comprises a first zone fixed to the first plate and a second zone fixed to the second plate, the first plate being linked to the second plate by a connection which has a degree of freedom in translation in a direction perpendicular to the direction of thickness of the wall in order to authorize contraction of the sealing membrane and a degree of connection according to

More precisely, when the temperature drops in the tank, the material making up the waterproofing membrane contracts, and to compensate for the waves the waterproofing membrane deploys. This means that the waves are more open at a cold temperature, for example when the tank is cold, than at a warmer temperature. When the tank is heated, for example when the tank is emptied, it is the opposite.
  • connection of the first plate to the second plate in the direction of thickness of the wall allows the dynamic pressures exerted on one of the first and second plates to also be taken up by the other plate, which ensures better distribution of stresses exerted on the wall.
