DEVICE FOR LINING OF CAISSONS

Provided is a lining method for a heat-insulating caisson, the method comprising: a step of inserting a cake of a heat-insulating lining, as a step of inserting the cake (36) of the flexible heat-insulating lining into an inner space (31) of the caisson, wherein the cake of the heat-insulating lining is inserted by thrusting the cake to a bottom wall (33) of the caisson along lateral walls by means of a thruster, and the cake of the heat-insulating lining is in contact with at least one lateral wall of the caisson; a step of applying pressure to an upper surface of the cake of the heat-insulating lining in order to compress the cake against the bottom wall; a step of, in order to release one side (40) of the cake of the heat-insulating lining from the lateral walls (6, 34) of the caisson, transforming the cake of the heat-insulating lining by deviation pressure between an edge of the upper surface and an area (43) of the upper surface spaced apart from the edge (44) of the upper surface of the cake of the heat-insulating lining; and a step of freeing the upper surface of the cake of the heat-insulating lining.
