Fuldatal Bridge Solms

The Fuldatal bridge Solms is with 1628 m the longest viaduct of the Hanover-Würzburg high-speed railway .

course

The double-track girder bridge is located at line kilometers 206.1 east of Solms, a district of Niederaula . The structure spans the Fulda valley with the Fulda , the B 62 and the Gründchenbahn between Niederjossa and Niederaula, the L3471 road between Solms and Mengshausen as well as a few field and farm roads. The track is located at a maximum height of 29 m above the valley floor.

The route runs straight on the bridge. The gradient initially drops in the northern third to the south and rises again in the two southern thirds.

To the north of the bridge there is the waiting kuppel tunnel , to the south the Richthof tunnel .

history

In 1976, variant III of the large-scale line layout in the Fulda area was intended to be a bridge 2145 m long and up to 35 m high.

The railway overpass was built between November 1984 and 1988.

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

During the construction phase, a loop of the Fulda in the construction area had to be temporarily relocated. A short section, which lies in the bridge route, was permanently relocated about 30 meters to the east. The trench dug for the temporary bypass is now used as a wetland habitat . The Bad-Hersfeld Road Construction Office was entrusted with the construction supervision and supervision (according to Section 38 of the Federal Railway Act). The structure was thus erected in full and under its own responsibility by the road construction authority, while technical supervision and budget management remained with the Deutsche Bundesbahn.

The pillars of the bridge were given nesting holes for kestrels at the suggestion of the state bird protection station . Since a complete compensation for the ecological interventions caused by the bridge was not possible close to the track according to the railway information, a replacement measure was implemented in Mengshausen, 5 km away . After five years of negotiations, this area was designated as a nature reserve on December 1, 1987 . In the following years the white stork settled in Niederaula again through this measure .

For the structure, 15,000 m³ of soil were excavated and 46,000 m³ of concrete (19,600 m³ of which for the superstructures), 3,600 t of reinforcing steel (without pile reinforcement) and 860 t of prestressing steel were used. The costs are given as 41.7 million DM.

technology

The bridge superstructure consists of a chain of 37 single-span girders . This enables individual bridge segments to be replaced later. The cross-sectional shape is a single-cell reinforced concrete box with inclined webs, prestressed in the longitudinal direction . In addition, the deck is prestressed in the transverse direction. The span is uniformly 44 meters with a superstructure width of 14.3 meters. The constant construction height of 4.0 meters is relatively high due to the required rigidity for the purpose of deflection limitation.

The wall thickness of the 8 to 21 m high pillars is 35 cm.

The abutments and piers are founded on 5,200 m running meters of large bored piles with a diameter of 150 cm . Below 6 to 9 m thick Quaternary layers of alluvial clay and gravel are stable rock layers of sandstone and claystone . The structure was founded up to 30 m deep in the chimney areas .

On both sides of the bridge there are parapets 1.50 m high, which serve as noise protection.
