In this pipe laying process, a reinforcing material (7), in the form of a curable artificial resin, is applied onto the jacket of a plastic pipe (4) with a predetermined stiffness, before insertion into a recess, e.g. in a pipeline. This material does not harden completely until a certain time has elapsed, i.e. after the pipe (4) has been placed in its desired position, and then increases the inherent stiffness of the plastic pipe. …<??>The device has means (5,6,7) for applying a reinforcing material onto the pipe surface. …<IMAGE>… |
