Project:
Stuttgart 21, planning approval phase 1.6a - Tunnel to Obertürkheim and Untertürkheim

The underground Stuttgart central railway station, will be connected with the maintenance railway station Untertürkheim, and the existing Filstal route near Obertürkheim, via the tunnel to Obertürkheim and Untertürkheim.

Planning focuses:

two single track tunnel pipes around 6.5 km long in closed construction, connecting structures every 500 m; underpass of the Neckar with shield fastening

Geology: Leached and non-leached gypsum keuper, sandstone and marl formations containing anhydrite; high swelling pressure in anhydrite; waterproofing structure to protect against penetration of ground water in the swelling soil layers

Start up concept taking into account restricted spatial conditions and how third parties will be affected
