Mechanized tunnelling technology for soft ground and hard rock Traffic and utility infrastructures Diameters 0.10–19m
More than 80 projects diameter >10m
More than 320km tunnel diameter >10m
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 infra- structure. Two Herrenknecht Double Shield TBMs (Ø12.43m) tunnelled under the Brisbane River for the Clem Jones Tunnel and two even larger Herrenknecht EPB Shields (Ø 12.45m) 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 head- quarters in December 2010.
