Flashes of Light at the End of the Tunnel
Aug 10, 2012
Excavation of a complex tunnel system for the XFEL European research facility in metropolitan area Hamburg was successfully completed in early June when the Herrenknecht AMELI tunnel boring machine entered its last target shaft. AMELI and its TBM sister TULA had to be relocated several times for the eleven tunnel sections between the research center DESY in Hamburg Bahrenfeld and Schenefeld in the district of Pinneberg. Exact laser technology provided by the Gesellschaft für Vermessungstechnik (VMT) kept the two TBMs perfectly on course over the route totaling 5.78 kilometers.
