The Eierberge Tunnel is a 3756 m long railway tunnel on the new Ebensfeld – Erfurt line between the route kilometers 87.365 and 91.121. It is located in the Upper Franconian town of Bad Staffelstein and is the southernmost tube of the 106 km long new line .

The structure is the third longest tunnel on the route and the longest in Bavaria. It belongs to the southernmost construction section of the new line. Together with a railway embankment, the 219 m long Main Bridge Wiesen , an 88 m long bridge over flood troughs of the Main, the Stadelbachbrücke railway overpass, another railway overpass and a road overpass, more than 140 million euros were invested.

course

The tunnel crosses the ridge of the Eierberge. The south portal is located in the Obermaintal near Nedensdorf in the so-called God's garden at a height of around 250 m. In front of the south portal, the ballast superstructure changes into a slab track . The north portal is located between Stadel and Püchitz .

The emergency exits 1 at route kilometers 88.219 and 2 at route kilometers 89.219 have rescue shafts , 18 m and 30 m deep with accessible connecting tunnels . Emergency exit 3 at km 90.219 is connected to a rescue area via a 380 m long rescue tunnel.

history

planning

In the route planning in 1995 and 1996, a structure with a length of 3756 m was planned.

On April 17, 2009, Deutsche Bahn AG announced the construction of the tunnel and other structures in this construction section (No. 3110, construction kilometers 1,400 to 9,090) across Europe. The contract was awarded on October 23, 2009 to a consortium of Austrian construction companies. The order volume was 160 million euros.

The period from January 11, 2010 to June 28, 2013 was planned for the duration of the construction project.

construction

The tunnel was built using the new Austrian tunnel construction method. After the first earthworks, traces of a 7,000 year old settlement were discovered at the incision to the northern portal. The work was interrupted until the finds were secured and documented by the Bavarian State Office for Monument Preservation .

The construction of the construction site began in spring 2010.

The solemn attack took place on July 7, 2010. Susanne Ramsauer, the wife of the Federal Minister of Transport at the time, Peter Ramsauer, took on the sponsorship of the longest tunnel in the Bavarian section .

The tunnel was driven from the center via an intermediate access gallery and from the north portal using the excavation and blasting method with shotcrete protection. It penetrates layers of the Lias delta and epsilon.

On May 24, 2011, the roof breakthrough occurred between the 1076 m long drive from the north portal and the 1890 m long drive from the intermediate attack to the north. In mid-August 2011, the drive with the 653 m long section from the intermediate access tunnel to the south was completed with the breakthrough at the south portal. The excavated cross-section was between 160 m² and 182 m².

South portal after the technical breakthrough

On August 29, 2011, the breakthrough ceremony took place at the south portal, at which the tunnel godmother and head of the railway, Grube , were present.

A total of 960,000 m³ of masses was excavated and used for terrain modeling. The outbreak that occurred during the intermediate attack was stored at the Eierberge landfill ( 50 ° 6 ′ 38 ″  N , 10 ° 57 ′ 9 ″  E ), northwest of the south portal. The northern outbreak was installed at the Weinberg landfill ( 50 ° 8 ′ 47 ″  N , 10 ° 57 ′ 5 ″  E ), northeast of the north portal.

The inner tunnel shell was produced starting from the north portal towards the south using a plastic sealing membrane in a double-shell, pressure-tight construction.

After completion of the inner shell, the tunnel was ready for shell construction at the end of September 2012. Deutsche Bahn celebrated this on October 5th together with the population and made it possible to view the tunnel shell. The expansion work, such as the filling of the bottom, the construction of sidewalks and the laying of the dry water pipe and cable pulling pipe routes in the shoulder should be carried out by spring 2013.

At the beginning of June 2011, an information point for the new line was opened at the south portal.

It is controversial whether the route should be fenced in around the tunnel portals.
