Map with all coordinates: The tunnel would have a railway - tunnel of Nuremberg-Erfurt high-speed railway with 745 m length. It lies between the route kilometers 118.940 and 119.685 in the area of the southern Thuringian city of Schalkau and is the southernmost structure on the route in Thuringia. The tunnel passes under the Mueß , a 461 m high ridge of Schalkauer plateaus , the foothills of the Thuringian Highland between Selsendorf and Roth (Schalkau) .
history
planning
On March 10, 2007, Deutsche Bahn AG announced the construction of the tunnel and the construction of the earthworks with the preliminary cuts in the south and north in the construction section no. 3211, construction kilometers 33.994 to 37.042, across Europe. The contract was awarded to a working group . The contracted construction work began in August 2007. The shell was completed in September 2010. The Day of German Unity in 2010 at the site, which at the former inner-German border , is celebrated with a day of open tunnel.
In autumn 2017, the track support plates in the tunnel were retrofitted with cover plates so that rescue vehicles could be driven over, and the cut-out in front of the north portal was fenced off.
The investment volume for the construction phase was 26 million euros.
Building
Most of the route in the construction section is curved in plan and has a gradient of 1.25% to the north. Originally, only one cut into the terrain was planned, but the 745 m long tunnel, which accommodates two slab tracks, was finally built . To the south of the tunnel there is a 1583 m long, maximum 25 m deep incision, followed by the Froschgrundsee viaduct . To the north of the tunnel there is a 476 m long, up to 22 m deep incision that merges into the Grümpental Bridge . The maximum cover of the tunnel is 22 m.
The Roth substation was built at the northern portal .
construction
Construction work on the tunnel began on February 29, 2008. As the tunnel godmother , Christine Zitzmann, district administrator from Sonneberg, triggered the first blast by pressing a button at the tunnel construction ceremony. By mid-July 2008 around 300 m had been driven through massive sandstones with intermediate claystones. During the construction phase, there were five explosions a day. In September 2008, the breakthrough was planned for the end of 2008. It finally followed officially on February 6, 2009.
The inner shell of the tunnel was made with 64 blocks. The regular cycle had a length of 12.5 m. The arch thickness is 60 cm. A so-called umbrella seal protects the structure against stratified water and groundwater.
The production of the incisions and the tunnel comprised 1.2 million m³ ground motion, mostly red sandstone , which (on the adjacent soil depot Muess 50 ° 22 '43 " N , 11 ° 2' 14" O ) were stored.
