Double Shield TBM Spec Sheet

Robbins Double Shield TBMs are the long-haul specialists of the tunnel boring world. Since their development in 1972, Double Shield machines have excavated some of the world’s longest tunnels and achieved world records in the process. The secret lies in their ability to simultaneously bore and line the tunnel with segments, making for faster excavation even in difficult ground.

TBM Disc Cutters in the Field: Extreme Tunnel Conditions Inform the Latest Cutting Tool Advancements | Paper Author: Steve Smading

Extreme tunneling conditions call for the most robust TBM cutting tools possible—whether that includes hard and abrasive rock, long-distance tunnels of 15 km or more, or high water pressures.  This paper examines the use of disc cutters under extreme conditions and the design aspects making the difficult tunneling process possible. Resulting cutter design changes and more will be outlined in the presentation along with initial results from field and laboratory testing.

Difficult Ground Solutions: A Methodology for Enhanced TBM Performance in Challenging Conditions | Paper Author: Doug Harding

In many rock projects, the occurrence of squeezing ground, high inrushes of water, blocky rock, and other challenges is a real possibility.  Today’s highly adaptable TBMs are capable of tackling these tough conditions using cutting-edge technology coupled with modern ground investigation methods. Difficult Ground Solutions (DGS)—a series of adaptable and customizable features for shielded TBMs—can reduce risk to contractors and owners while providing accurate ground investigation.  This paper covers difficult ground solutions informed by field experiences, the tools it takes to be successful in such conditions, and how they are applied. Example projects will be discussed from the U.S., Turkey, Nepal, and more.
