The Filder Tunnel is the longest tunnel on the new line between Stuttgart and Ulm, connecting the new main railway station with the Filder plain and the airport. A convertible multi-mode TBM from Herrenknecht with a shield diameter of 10.82 meters excavated the twin-tube, 9.5-kilometre-long tunnel. In the upper section of the Filder tunnel, it worked in closed mode with screw conveyor, in the lower Filder tunnel in open mode with conveyor belt discharge. The TBM installed over 54,000 reinforced concrete segments weighing up to 15 tons.

Increasing production through automation

For the production of the segments, Max Bögl needed an automated system that could be flexibly adapted to the existing building and infrastructure and would enable the segments to be handled quickly from the mould to the outside storage yard.

 

Herrenknecht Formwork's customized finished line comprised all work steps: transporting, curing, stacking, turning the stacks, separating, turning and applying the seal.
