Pipe Jack 1350mm RCP for 30m.
The original pipe had collapsed and because the corrugated pipe could not be cut using air grinders, it was decided to jack a new 1350mm pipe beside the original one.
A 1350mm RCP has an OD of 1500mm. The 30m of 1500mm was hand dug and the pipe jacked in using the case boring machine between the 2 dams. |
