The Rehtalbrücke is a 204 m long, double-track railway overpass structure on the new Ebensfeld – Erfurt line , which connects the Masserberg tunnel with the Rehberg tunnel . The bridge stands in southern Thuringia west of Goldisthal and spans the Rehtal with an arch of 107 m span, a deeply cut valley with very steep valley flanks.
The route , at a maximum height of 54 m above the valley floor, runs in a straight line to the middle of the bridge, after which a transition curve begins . It is designed for a speed of 300 km / h and has a maximum longitudinal incline of 4 ‰ in the area of the bridge. The bridge has a slab track with a distance of 4.5 m between the tracks , which can be used by rescue vehicles. The structure lies between the route kilometers 135.739 and 135.943 of the new route.
history
Together with the Masserberg and Rehberg tunnels and the Dunkeltalbrücke, the bridge is part of the 2.3 km long construction section 3212 ( Southern Thuringian Forest ), which was commissioned in January 2010 with an award amount of € 70 million and should be completed in 2013.
On November 8, 2012, the road slab of the last superstructure section was concreted. This was done from the center of the arch to the right and left at the same time. The Rehtalbrücke was the last bridge structure in the Thuringian section to be completed. The shell of the bridge was completed at the end of 2013.
construction
The 204 m long superstructure has the cross-sectional shape of a single-cell reinforced concrete hollow box with inclined webs, prestressed in the longitudinal direction . In addition, the deck is prestressed in the transverse direction. The maximum width of the superstructure is 14.1 m. The construction height is 2.7 m, the construction height 3.6 m. To the south and north of the arch there are two- span girders each with a span of 24 m, the horizontal fixed bearings of which lie lengthways on the two abutment pillars . Above the arch there is a continuous girder with five openings, each with a span of around 20 m and a horizontal fixed support in the longitudinal direction across the center of the arch. The superstructure has no rail extensions .
The reinforced concrete arch with a span of 107.45 m and a pitch of 24.7 m has variable dimensions and a full cross-section in some areas. It was built on a shoring and was closed in June 2012.
