Fluidtransportleitung.

摘要

The conduit has a large transverse cross-section, constituted by the assembly onto an installation surface of a plurality of prefabricated longitudinal elements placed one after another and comprising, in cross-section, a lower base and a roof comprising two lateral edges linked to the base by leak-tight longitudinal joining members. …According to the invention, the longitudinal joining members are constituted by two parallel metal sectional bars linked rigidly together by at least one bracing part and fixed onto a slab 1 constituting the base of the conduit, and the roof is constituted by at least one thin wall element and is fixed in a leak-proof fashion by its two lateral edges along the two longitudinal sectional bars. …The invention applies especially to the production of a conduit for conveying a fluid under pressure, for example for water supply, urban heating or pen stocks. ……
