SLURRY MICROTUNNELING (MTBM)
Microtunneling systems are the optimal choice for smaller diameter, unmanned
tunnel boring projects. With these systems, the tunnel boring machine (MTBM)
is driven and monitored remotely from the surface and is capable of single pass
installations on line and grade per industry standards. The surface-located
operation room houses the operator station and drive motor controls for the
MTBM and its slurry pumps. Hydraulic power units for the main and intermediate
jacking stations are housed separate to the operation room. Robbins has a full
staff of field service and support personnel to train and assist as needed to
ensure successful project completion.

curved drives
• Drives requiring specific casing t t
types such as RCCP, vitrified
clay, polymer-concrete, and
steel casing

VERSATILE TUNNELING
Robbins MTBMs bore tunnels with
unique and versatile specifications
that are determined by customer
preference as well as project and
technical requirements.

Ranging in diameter from
DN 250 to DN 3000.
Soft ground, mixed face or
rock formations.
Standard systems can operate
with hydrostatic head up to 3 bar.
Boring units of DN 1100 and larger
can be manufactured with face
access, which allows back-loading
cutting tools to be safely changed
and inspected from
within the MTBM.
Offers both analog and digital
guidance/data logging systems
Custom-sized machines are
