| Abstract: | 50 Jahre nach ihrer Erbauung weicht die 665 m lange Talbrücke Heidingsfeld einem Ersatzneubau. Dabei kommt für den Stahlverbundüberbau aus dem Jahr 1964 erneut ein Stahlverbundquerschnitt zum Zuge, der je Fahrtrichtung durch einen modernen einzelligen Stahlhohlkasten mit außenliegenden Kragarmen und aufbetonierter Fahrbahnplatte gebildet wird. Aufgrund der topographischen Verhältnisse und der Bedingungen zur Aufrechterhaltung eines 4+0-Verkehrs erfolgt die Montage durch Längseinschub der Stahlkonstruktion mit Stützweiten bis zu 120 m. Replacement of the viaduct Heidingsfeld. 50 years after its construction the 665 m long viaduct Heidingsfeld will be totally replaced. Hereby the steel composite superstructure from 1964 is constructed again as a steel composite section, which is formed in every roadway by a modern unicellular steel box with external cantilevers and concreted slab. Due to the topographical conditions and the conditions for maintaining a 4+0 traffic the steel construction will be installed by longitudinal launching with spans up to 120 m. |
