The Sinnberg tunnel is a 2159 m long railway tunnel on the high-speed line Hanover – Würzburg , east of the Lower Franconian town of Rieneck. The tube accommodates two tracks, which are planned to be traveled at up to 250 km / h.

course

The tunnel runs in a north-south direction. The north portal is in a straight line, the rest of the tunnel in an arc of 7,000 m radius, which is followed by transition arcs on both sides . The gradient drops in a southerly direction with a continuous 1.5 per thousand.

The tube lies in layers of red sandstone . The cover is up to 120 m. It is located in the Rieneck and Schaippach districts .

To the south, after a short earthwork section, the Schaippach Sinntal Bridge joins. The Burgsinn depot follows to the north .

history

planning

According to the planning status from the end of 1977, a length of 2042 m was planned for the structure. The course of the route and the gradient already corresponded to the later realized design. In autumn 1981 the planned length was 2065 m.

construction

The work was awarded on December 2, 1980 to a consortium of the Kunz, Züblin and Kronibus companies. The construction work began in the same month (in the same month construction also started on the One Mountain Tunnel ). The tunnel was one of the first structures to be built on the high-speed section between Fulda and Würzburg.

The tunnel was posted on February 25, 1981. The tunnel sponsor Sonja-Maria Maak, the wife of Helmut Maak , the former construction manager for the new line in the southern section , triggered the first blast on February 25, 1981 with the push of a button. It was the first tunnel stop on the route.

At the start of construction, the planned length was 2,065 m ( construction kilometers 269.996 to 271.061), the construction costs were 55 million D-Marks . 430,000 cubic meters of material were to be removed from the mountain.

The tunnel was built using shotcrete . An intermediate attack was made in the Stiebal valley. 180 men worked on the construction site.

The tube was originally supposed to be punched through on August 10, 1982. Due to difficult geological conditions, there were delays, which also caused the construction costs to rise by five million Deutschmarks. On September 28, 1982, the tunnel sponsor symbolically completed the tunneling work with the last blast.

During the construction phase, the tube was also referred to as "Object 24". The shell of the building was finished and accessible as early as 1983. It was completed as the first tunnel in the southern section. In August 1985 the tracks had already been laid in the tunnel.

business

Test drives were carried out in the tunnel to prove that the rail vehicles were pressurized .

technology

There are two pre-signals for the Burgsinn depot and two block markings in the tunnel .
