Special-shaped TBM

Tube Curtain Machine

The tube curtain machine jacks steel pipes to form a 'pipe curtain' as advance support, suiting large-section, shallow-cover excavations where minimal ground settlement and high safety are required.

Configuration and engineering

Every CRCHI TBM is engineered to project. Shield diameter, cutterhead geometry, drive power, segmental ring design and back-up arrangement are configured to the alignment, ground conditions and water pressure of the drive. Project-specific scope beyond the standard envelope is engineered to brief, and where a drive calls for it, a machine is developed from the ground up. CRCHI Australia is the engineering, commercial, commissioning and aftermarket point of contact for Australian projects.
