The tunnel Baumleite is a railway - tunnel of new Ebensfeld-Erfurt of the 1317 meters in length ( kilometer 121.363 to 122.680) in Schalkau ( Thüringen ). It was part of construction section 3211 of the new line and crosses under the Baumleite ridge, which is up to 528.6 m high , an extension of the Thuringian Slate Mountains , more precisely the Southern High Slate Mountains, and therefore bears his name.
location
The south portal of the tunnel is around half a kilometer northwest of the Grümpen district of the Frankenblick community .
The Theuern overtaking station follows the tunnel to the north in a long cut . The Grümpentalbrücke connects to the south of the tunnel .
Geologically, the tunnel runs continuously in the Lower Muschelkalk , which has karst features.
course
The gradient rises steadily towards the north portal at 12.5 per thousand.
The overburden in the area of the south portal is around 23 m and increases to around 30 m. In the middle third of the tunnel, it drops to around 8 m, to rise again to around 24 m in the northern third. Towards the north portal, the cover drops again to 14 m above the tunnel ridge .
At route km 121.945 to the west of the tunnel, at a center distance of 30 m, there is a rescue shaft about 39 m deep, which is connected via a cross tunnel to emergency exit 2 and via an 87 m long, accessible parallel tunnel at route km 121.858 to emergency exit 1. The rescue area at the shaft building is connected to federal road 89 via a forest path. The third emergency exit at km 122.445 leads to the north portal via an accessible, 235 m long parallel tunnel. This means that there is a maximum distance of 500 m between the emergency exits.
history
planning
Deutsche Bahn announced the tender for the construction of the tunnel in March 2008 for August of the same year. The tender for the shell of the tunnel was published in mid-October 2008. The estimated net contract value for the construction of the tunnel, emergency exit, incision and dumping of the excavation is 39.5 million euros (as of March 2008). In mid-2010, an investment volume of 50 million euros was stated.
The submission took place on December 18, 2008. The construction contract will run from May 2009 to early January 2012. In addition to the tendered service, a walk-in escape tunnel running parallel to the main tube was commissioned, which consists of two sections 235 m and 80 m in length.
construction
The tunnel was built using shotcrete from the north portal to the south. The estimated total excavated mass was 240,000 m³. In addition, a cut of around 16,000 m³ was built.
The solemn attack took place on October 14, 2009. The mayor of Sonneberg , Sibylle Abel, was the sponsor of the tunnel .
On May 26, 2010, 1000 meters of the tunnel had been driven. The breakthrough was celebrated on July 15, 2010. In June 2011 the inner tunnel shell was completed. Work on the tunnel was completed at the end of 2011.
The excess masses were placed on the Galgenberg Ost landfill ( 50 ° 25 ′ 2 ″ N , 11 ° 1 ′ 32 ″ E ).
On May 17, 2012 (Ascension Day), more than 1000 visitors hiked through the tunnel that was open on that day. On March 25, 2017, around 300 rescue workers trained in an emergency in the tunnel.
business
On September 1, 2019, an ICE was due to a technical defect in the tunnel for more than two and a half hours. 500 travelers were evacuated on a subsequent train.
