Pipe installation requires precision and skill. It must be done by professionals who have experience in the engineering and construction involved in the process. Laying underground pipes without digging a trench offers an effective solution and Abergeldie can help.
Our team can efficiently construct horizontal pipe jack tunnels which can provide conduits for underground services. We have successfully adapted modern Tunnel Boring Machine (TBM) technology to complex ground conditions and can jack pipes to 3.0m external diameter in hard rock or soft material easily. Abergeldie’s tunnelling engineers are extremely experienced in trenchless tunnel construction.
PIPE JACKING PROJECTS:
Typical of our work is an 87m long pipe jack tunnel for Ausgrid in Burrows Road Alexandria, Sydney. The 2800mm diameter tunnel carries 6 x132kV cable circuits which form a part of the reconfigured Energy Australia Network from TransGrid’s Beaconsfield South substation. An Earth Pressure Balance Machine (EPBM) was used to overcome the difficult water-charged ground conditions.
Abergeldie has successfully provided Ausgrid with several similar pipe jacked, cable housing tunnels over previous years, including a tunnel at Artarmon, 111m long and 1650mm diameter excavated in sandstone; another at Pymble, 97m long and 1650mm diameter bored through shale; and most recently at Carlton, a 120m long and 2400mm diameter tunnel through sandstone. All of these projects included construction of permanent access structures that were used initially as send and receive pits. The projects also included fit out of the tunnels with the necessary cable support brackets so that the cables could be installed later by others.
