PROJECT OVERVIEW.
Long distance capability eliminates manholes.
Menangle Rd is a busy, two lane arterial road joining Menangle Park and Campbelltown. Menangle. The pipe alignment followed an existing VC pipe which was under capacity. It essentially followed the verge of the road and at times beneath the road pavement. Ground conditions were favourable being self-supporting shale, which allowed microtunnelling extended distances. This minimised the number of bends required in the line and also negated the need for change of direction manholes.
Roadside Site Setup that maintains traffic flow
The shafts were dug adjacent to the road pavement meaning Pezzimenti’s container trucks setup on line with the pipe were ideal – also considering the overhead wires in the vicinity – with no overhead cranage allowed. The power pack is inside the container truck itself so it is ideal for tight areas. The vacuum and slurry bins were setup on the other side of the shaft also in line with the pipeline keeping the work area as narrow as possible. This setup allowed the project to be completed without any lane closures an maximised traffic flow.
Roadside microtunnelling – capability to set the trucks up inline allowed the busy road to stay open.
Site Setup – A vacuum truck is ready to transport spoil.
