The present invention relates to a caisson structure intended to form part of a stack of such caissons constituting the lateral walls of an undergound room such as particularly a cellar, wherein each caisson is constituted by modular elements including at least one portion with vertical walls in U arrangement and a portion constituting the top wall of the caisson and nestable into the U-shaped portion.

The present invention relates to an underground room, such as notably a cellar, including a floor, a ceiling and lateral walls formed notably by stacked box-sections, prefabricated from concrete, the entire assembly being accommodated in an excavation sunk under a floor slab of a structure, this excavation being lined with a fluid-tight enclosure and provided with a bed of sand. The underground room has vertical posts or columns of reinforced concrete extending from the floor to the level of the ceiling thereof, and having a portion of a predetermined shape. The walls of the stacked box-sections have vertical edges of a shape corresponding to the predetermined shape of the portion of the columns, with the vertical edges bearing against the columns so that the box-sections act as supporting walls to withstand the earth pressure.
