Abstract:
1. An assembly comprising: a pipe for transporting liquid having a longitudinal axis and being flexible, deformable between a circular internal section and a flattened internal section which may be zero, and foldable longitudinally on itself, and a device for laying the pipe at a site, the laying device having a longitudinal axis and comprising a rotary drum around which a first pipe portion is wound, wherein the first pipe portion is wound around the drum in a state in which its section is flattened, along a flattened strip, the laying device further comprising: a motorized paying-out device for unwinding the pipe, positioning means for positioning the first pipe portion output by the drum opposite a second portion located downstream of the first with respect to the pipe laying direction, in a state in which the portions are shaped so as to match one another, their sections being less flattened than on the drum, joining means for a watertight connection between the first and second pipe portions in the state in which they are shaped so as to match one another, and for obtaining the elongate pipe, and, tensioning means for transmitting to the elongate pipe an axial tension for advancing downstream and/or for moving back upstream.
