WORLD LEADER IN LARGE DIAMETER TBMs.

摘要

Construction companies have successfully excavated more than 320 kilometers of traffic and utility tunnel with diameters of more than 10 meters using Herrenknecht technology. In Shanghai the two world's largest Mixshield TBMs, Herrenknecht S-317 and S-318,Ø 15.43m, excavated three-lane road tunnels under the Yangtze River. The two giants finished their 7.5km drives one year ahead of schedule and the tunnels could be opened to the public in time for the 2010 WorldExpo. Brisbane is reducing above-ground road traffic significantly by investing in efficient underground infrastructure. Two Herrenknecht Double Shield TBMs (0 12.43m) tunnelled under the Brisbane River for the Clem Jones Tunnel and two even larger Herrenknecht EPB Shields (012.45m) are being used for Brisbane's Airport Link. The world's largest tunnel boring machine, the EPB Shield for the Galleria Sparvo road tunnels in Italy with a diameter of 15.55m has successfully passed workshop acceptance at the Herrenknecht headquarters in December 2010.
