The use of TBM (tunnel boring machine) gradually increases in worldwide tunneling projects. TBM machine are often applied to more difficult and complex geological conditions in urban area, and many problems and difficulties have been reported due to these geological conditions.
RETC is proud to present more than 21 technical sessions featuring the leading practitioners in the tunneling industry from across the U.S. The primary focus of the technical program is to add value to the industry through examination of the most innovative practices and products currently in use.
Featured Projects | Mexico City, Mexico Túnel Emisor Poniente (TEP) II. A Robbins Crossover (XRE) TBM was chosen to bore a 5.8 km (3.6 mi) tunnel as part of Mexico City's wastewater management efforts, making it the first Crossover machine to bore in North America.
Digging the new tunnels was a 24-hour a day job, 7 days a week. Crossrail used eight tunnel boring machines (TBMs) to construct the new rail tunnels under London. The giant machines carefully weaved through the capital's congested sub-terrain, snaking between the existing Tube network, sewers ...
Apart from cut and cover and blasting, Tunnel Boring Machine (TBM) is a commonly used construction method in building tunnels nowadays. The type of tunnelling method to be used depends on the specific geology of the project, tunnel length or diameter, logistical arrangements, environmental and other factors.
