The Danube Bridge Fischerdorf is a 661.5 m long motorway bridge in Deggendorf , Lower Bavaria . The building, named after the village of Fischerdorf in the southeast, belongs to the federal motorway 92 and spans the Danube between the Deggendorf motorway junction and the Deggendorf-Mitte junction at river kilometer 2285.49 .
In the course of the bridge, the motorway is straight in plan, only the last 111 meters on the northern side are curved. In addition to Eginger Strasse, the railway line from Deggendorf to Hengersberg is crossed there. The bridge consists of the 279.5 m long southern and northern approach bridges made of prestressed concrete and the steel 102.5 m long river bridge, a tied arch bridge . The bridge was built between 1988 and 1991 at a construction cost of 34 million DM.
Approach bridges
superstructure
The prestressed concrete bridges consist of two separate superstructures and, as a structural system, have the continuous beam in the longitudinal direction . They each have five fields with spans of 55.3 m + 4x55.0 m. The transitions to the current bridge on the two separating pillars have bearing spacings of 2.2 m. Expansion joints are also arranged there. In the transverse direction, the superstructures are designed as single-cell prestressed hollow boxes with a constant construction height of 2.36 m and a 2.5% gradient. The walkways are inclined, the floor slab is 5.0 m wide, the deck slab 11.5 m.
The construction was carried out using the incremental launching method with temporary intermediate supports that required pile foundations. The first concreted superstructure was initially concreted in the axis of the opposite lane and then moved transversely into its final position. This was followed by the production of the superstructure for the other lane.
Foundation and substructures
The two superstructures rest on flat , solid, granite stone clad reinforced concrete pillar discs with a length of 19.55 m and a width of 2.5 m. The width of the dividing pillars is 4.0 m.
River bridge
superstructure
The main span over the Danube with a span of 102.5 m consists of a tied arch bridge with a single central, circular arch to which two steel composite hollow girders of the superstructure, the same height and width as the approach bridges, are attached.
The steel arch has a radius of 84.8 m and has a 1.2 m high box profile as a cross-section, which is 1.0 to 1.6 m wide. Eight hangers with a double-T cross-section up to 50 cm wide are arranged at a distance of 12.0 m and guide the loads from the up to 1.2 m high cross members into the arch.
The tied arch bridge was delivered in 21 parts and installed on the southern approach bridge. With the help of two platform cars and a floating ship, the construction was finally pushed in.
