A method and an apparatus for pushing forward pipes along a pipe line section by which an apparatus is arranged to be brought down into a manhole connected to the pipe line section, and includes a pushing piston (20, 26) exerting a pushing force on a pipe (8, 12) with support of a holding-up device (2, 18). The pushing piston (20) at its leading end carries rods (27) extending essentially to the rear end of the pushing piston and there carry a pressure abutment (28) for bringing the pipe with it during the forward pushing movement of the piston, said rods (27) aiding in supporting the pipe (8). |
