Solutions package
Pipe-Jacking Package
For utility contractors, civil contractors and infrastructure asset owners delivering trenchless drives in Australia. The package covers the four working modes CRCHI builds for the technique: round-bore slurry-balance micro-tunnelling for cable, water-supply, drainage, gas and utility-corridor pipelines; rectangular box-section pipe jacking for pedestrian underpasses, metro station entrances and culverts; direct-pipe laying, where the pipeline is welded to the TBM tail and jacked continuously into the ground in a single pass with no reception shaft; and a mining-mode slurry-balance variant for drives launched from inside an active mine, including coal-mine gas drainage. A separate pipe-roofing machine installs jacked steel tubes as a pre-support arch above tunnels passing beneath operational highways, railways or sensitive surface assets.
Who it's for
Utility contractors, civil contractors and infrastructure asset owners installing trenchless utilities, underpasses or jacked pre-support beneath operational corridors in Australia.
When to specify this package
- Sewer, water, gas or drainage mains crossing under operational rail or road corridors.
- Box-section pedestrian underpasses or metro entrances under existing roads, plazas or rail corridors.
- Long-distance gas, water or oil-pipeline drives, including river crossings, preferring single-pass installation over open-cut.
- Pipe-roof pre-support above tunnels or station boxes passing under settlement-sensitive surface assets.

Scope of supply
Primary trenchless drive
Match the machine to bore shape and drive mode: round-bore for utilities, rectangular box-section for underpasses and station entrances, direct-pipe for continuous single-pass pipeline laying, and the mining-mode variant for drives launched from inside a working mine.
Tunnel Boring Machines
Slurry Balance Pipe Jacking Machine
Round-bore slurry-balance micro-tunnelling for urban cable, water supply, drainage, gas and utility-corridor pipelines.
Tunnel Boring Machines
Rectangular Pipe Jacking Machine
Box-section pipe jacking for pedestrian underpasses, metro station entrances and culverts.
Tunnel Boring Machines
Direct Pipe Laying Machine
Slurry-balance TBM mated to a pipe thruster; pipeline pre-welded to the machine tail and jacked into ground in a single pass with no reception shaft.
Tunnel Boring Machines
Mining Pipe Jacking Machine
Slurry-balance variant configured for underground mining duty, including coal-mine gas drainage drives launched from inside an active mine.
Pre-support beneath operational infrastructure
Where a tunnel or station box passes beneath an operational rail or road corridor, a jacked steel-tube arch installed first carries ground loads while the tunnel below is excavated under its protection.
Engineering and R&D
CRCHI Australia brings full OEM engineering and R&D capacity to every package. Most catalogue equipment is configurable to project requirements; project-specific scope is engineered to brief; and where a project calls for it, a complete solution is developed from the ground up. Typical tailoring on trenchless drives includes cutterhead configuration, slurry-circuit sizing, articulation geometry, pipe-thruster pairing and welded-tail interface matched to the drive and ground.
