Project Description
Overview
Rob Carr has completed the trenchless component of the Parramatta Light Rail project. The project involved the installation of DN1200 and DN1500 reinforced concrete jacking pipe required to augment the local drainage system. Both drives were launched from a 6.0m deep launch shaft at Centenary Square.
The DN1500 drive in particular entailed a singular 492m long journey along Parramatta’s busy restaurant district on Church Street with the machine reaching its destination at the retrieval shaft at Lennox Bridge earlier this month. The TBM had to traverse along a series of complex alignments, guided by the TBM operator using a VMT guidance system, ensuring the tight grades and tolerances were achieved upon completion of the tunnel.
