Beschreibung
Zusammenfassung:	The method involves providing a larger pipe with an outer protective layer (11) and a sheathing layer. The larger pipe is laid together with a smaller pipe (12), a line or a cable. The smaller pipe is enclosed by the protective layer or the sheathing layer such that the pipes, the line or the cable form a pipe unit (14), where the smaller pipe is an empty duct for the cable or the line. An inner core barrel (13) of the larger pipe is extruded from plastic while producing the pipe unit, where the smaller pipe and/or the line or the cable is positioned at the inner core barrel.
