Excavation of Feuerbach Tunnel Is Finished

摘要

And once again the Stuttgart 21 project: Driving for the Feuerbach Tunnel, which connects the existing railway lines to and from Mannheim, Karlsruhe and Paris with the future Stuttgart Central Station, was completed with a tunnel breakthrough on June 5, 2020 after a construction period of around five and a half years. The breakthrough took place at a depth of around 15 m shortly before Feuerbach station. A joint venture consisting of the companies Ba-resel GmbH, Alfred Kunz and Walo Bertschinger AG from Switzerland had been commissioned with the construction of the tunnel in 2012; driving for the Feuerbach tunnel started on 10 December 2014 from the intermediate heading Prag. From this access tunnel, the two single-track bores were driven in the direction of both the main railway station and Feuerbach using the conventional excavation method. From the opposite direction from Feuer-bach station, the double-track section of the tunnel was built in parallel. For this purpose, the existing tracks at Feuerbach station had to be moved four times during ongoing operations.
