Abstract (en)
The invention relates to a tubular structure consisting of sections placed end to end and resting on a flattened and compacted laying surface (61). Each section is formed from juxtaposed wall elements comprising two side elements (2, 2') with an inwardly curved lateral wall, each bearing on the laying surface (61) by means of a stabilising member with a flat bottom, allowing the side element to stand up without scaffolding, characterised in that each side element (2, 2') is equipped at its base with a widened sole (7) comprising two wings (71, 72) extending horizontally in a projecting manner on either side of the lateral wall (20) of the element (2, 2'), the latter comprising a substantial vertical lower part (26) perpendicular to said sole (7) and extended upwards by an inwardly curved upper part (21). The present invention is used for conduits of very large cross-section which can be employed for the construction of underground passages for various uses. <IMAGE>
