The invention concerns a tubular structure comprising, in cross-section transverse to its axis (O), at least three prefabricated elements, respectively two side wall elements (32, 32') resting on the setting surface and at least one upper element (31) with a curved profile resting, along two longitudinal joints (36), on the upper edges of the two side wall elements (32, 32') and tangentially connected thereto to form a continuous vault for transmitting loads on the bases (33) of said side walls (32, 32'). The invention is characterised in that at least some of the side wall elements (32, 32') are shaped so as to possess sufficient rigidity for carrying the applied loads without lateral support on an embankment covering the structure.
L'invention a pour objet un ouvrage tubulaire comprenant, en section transversale à son axe (O), au moins trois éléments préfabriqués, respectivement deux éléments de piédroits (32, 32') reposant sur la surface de pose et au moins un élément supérieur (31) à profil incurvé reposant, le long de deux joints longitudinaux (36), sur les bords supérieurs des deux éléments de piédroits (32, 32') et se raccordant tangentiellement à ces derniers de façon à former une voûte continue pour la transmission des charges sur les bases (33) desdits piédroits (32, 32'). Conformément à l'invention, au moins certains des éléments de piédroit (32, 32') sont conformés de façon à présenter une rigidité suffisante pour encaisser et transmettre les charges appliquées sans appui latéral sur un remblai recouvrant l'ouvrage.
