Abstract (en)
[origin: WO2007104839A1] The invention relates to an underground passageway with a plurality of passageway sections beneath a backfill of variable height. According to the invention, the passageway consists of a plurality of adjacent conduits (A, B) with parallel axes, each bounded by a wall (3) consisting of juxtaposed prefabricated elements and resting on a laying surface (15), the whole being covered by a backfill having an upper part forming a platform (2) whose level can vary with respect to the ground (14). The dimensions of the prefabricated elements each constituting adjacent conduits (A, B) are determined according to the position of the conduit along the platform, such that each conduit has a height with respect to the ground (14) which is less than that of the platform, each conduit being covered by a minimum height (e) of backfill.
