The viaduct Bauer stream with a length of 748 is the second longest railway bridge m of Mannheim-Stuttgart high-speed railway . It crosses the Bauerbach valley near the district of Bauerbach in the Baden-Württemberg district town of Bretten and therefore bears its name. The bridge crosses the Kraichgaubahn among other things .
Location and course
The prestressed concrete bridge lies between the route kilometers 56.385 and 57.131.
The route runs in a south-easterly direction initially in a straight line that turns into a right-hand arc of 7,000 m radius. The gradient rises continuously in the same direction at 0.941 per mil.
construction
The bridge corresponds to the framework planning of the Deutsche Bundesbahn for new line viaducts. The structure has 16 pillars with a field spacing of 44 m. The superstructure is designed as a single span girder chain.
history
planning
The bridge was already planned in the planning status of the new line from 1973, with a length of around 900 m and a height of up to 40 m. On the further route towards Stuttgart, a depot should follow at 59.5 km.
The public hearing took place on July 19, 1979 in Bauerbach.
The structure with its length of 748 m, which was realized later, was planned as early as 1983. The construction costs amounted to around 21 million D-Marks . The total costs were put at 25 million DM around 1986.
construction
Construction began in March 1984 with earthworks. The actual bridge construction followed in August 1984 with the first foundations. For the foundation of the building, the subsoil that was not very stable in places had to be replaced. Some of the up to 38 m high pillars were founded on large bored piles. The pillars were then raised in 4 m sections using climbing formwork. Subsequently, the superstructure was created using a telescopic arm. The individual superstructure elements were created every two weeks.
The last part of the superstructure was completed in February 1986. On March 7, 1986 a bridge festival was celebrated.
The structure was built by the ARGE Talbrücke Bauerbach , which was formed from the companies Strabag and Dyckerhoff & Widmann .
During the construction phase, numerous measurements were taken on various components. The findings should be used to assess the substructure stiffness for further valley bridges.
business
The bridge advisory board of Deutsche Bahn, newly established in 2007, classified the bridge, which was completed in 1986, as "boring".
