Abstract (en)
[origin: FR2776135A1] The conduit consists of a sheath (2) enclosing a channel (3) which may carry cables or optical fibres. The sheath includes a continuous cavity (5) which houses an insulated conductor (4,4a) used to provide electromagnetic detection when the conduit is buried. Each section of conduit has an end section (60) which uses internal channels (64,66) to compensate for any angular displacement between conduit sections
