The Krämerskuppetunnel is an 838 m long railway tunnel on the high-speed line Hanover – Würzburg . It crosses under the Krämerskuppe to the west of the Reckerode district of the north Hessian municipality of Kirchheim and therefore bears his name.

course

The building passes under the federal motorway 7 at an acute angle over a length of 170 m in the area of the south portal . The coverage in this area is 6 to 15 meters.

View from the north portal of the tunnel during the construction phase (approx. 1989)

The Wälsebachtalbrücke connects to the south and the Kirchheim depot to the north . There are four points of the depot in the tunnel .

The building crosses layers of the Middle Buntsandstein with layers of clay and sandstone.

geology

In the area of the motorway underpass, there is medium red sandstone from Dethfurther alternation with close clay and sandstone sequences.

history

planning

At the beginning of 1984 the structure was planned to be 810 m long at a cost of 23.7 million DM.

The structure was part of planning section 15 in the middle section of the new line.

In the course of the construction planning, various construction variants were examined for the southern part of the intersection of the new line and the motorway (approximately up to its axis). These included an open construction method with temporary relocation of the motorway (at an estimated cost of between 2.80 and 4.37 million DM) and various variants of mining construction (3.30 to 3.62 million DM). Since the construction of the tunnel was unavoidable during the main travel season for scheduling reasons, the road construction administration demanded that restrictions on the trunk road be avoided as far as possible. The open variants considered were therefore ruled out. Ultimately, the decision was made in favor of tunneling using a pipe umbrella.

construction

Construction began in April 1984. The building was on July 11, 1984 struck and in March 1985. punctured .

The tunnel was driven using the new Austrian tunnel construction method. The excavated cross-section was 140 m². A total of around 110.00 m³ of material was excavated, around 4,000 anchors were set and around 9,000 m³ of shotcrete was poured in.

The 170 m long crossing under the motorway proved to be particularly complex. An above and below ground measurement program accompanied this tunneling section. The measurement results were checked daily. Ultimately, the specified settlement dimension was not exceeded.

A working group under the technical management of the company Beton- und Monierbau was commissioned with the construction .

After 15 months of excavation and nine months of expansion, the structure (status: approx. 1984) should be completed in March 1986. It went into regular operation in 1991.
