SLURRY MICROTUNNELING (MTBM)

ROBBINS SBU DIVISION

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.

MTBM APPLICATIONS

• Soft ground, mixed face and rock tunneling projects

• Operates below the water table up

to 3 bar pressure

• Machines built to suit DIN

Standards as well as common

U.S. Standards

• Line and grade sensitive drives and

curved drives

• Drives requiring specific casing

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

also available.
