Complimentary Webinar: Performance Under Pressure

Join Robbins Engineering Manager Brad Grothen and Robbins Chief EPB Engineer Shinichi Konda as they discuss EPB TBMs.

Join Robbins Engineering Manager Brad Grothen and Robbins Chief EPB Engineer Shinichi Konda as they discuss EPB TBMs.

Earth Pressure Balance Machines (EPBs) are by far the most widely used type of TBM in the tunneling world, but their proper design and use in varying geologies is not often discussed. Clay, sand, gravel, mixed face conditions and boulders each require unique EPB designs and expert operation. Whether that means utilizing abrasion resistant plating, heavy duty screw conveyors, or customized cutting tools, today’s EPBs are up for the challenge. With regards to operation, using the right RPM, the proper additives, and detailed monitoring can keep subsidence at a minimum and reduce downtime.

In this complimentary 60-minute webinar, Robbins Engineering Manager Brad Grothen and Robbins Chief EPB Engineer Shinichi Konda will explore how EPB TBMs work, their various designs, and real-world applications. They will draw from field data in multiple types of geologies to make informed recommendations on EPB design and operation. Areas for advancement will also be discussed— including high tool wear and the ability to properly form a plug.

We invite you to submit your questions beforehand to webinars@robbinstbm.com to get a thoughtful and well-researched answer during the Q&A session at the end of the webinar.
