摘要 |
The machine for laying a composite pipe consists of a coiled inliner (1) made of relatively soft material. Inside an elongated hole (3), a pipe (7) is wound by a winder (4) out of a strip (5) with elongated, profiled reinforcement-ridges (6). The pipe (7) has lateral connections (8) with tongue and groove formation. Between the inliner (1) and the elongated hole (3) is pressed a setting material (2b) such as concrete. USE/ADVANTAGE - Water-tight and non-corrosive inliners and casings for pipes are laid underground. |
