The two superstructures of the 450 m long and 62 m high Lahntal Bridge each consist of two haunched, longitudinally prestressed hollow girders that were erected in cantilevered cantilevering. 170 t external pre-tensioning 500 t internal pre-tensioning Installation, stressing and injection Procedure: BBV L15 BBV L15E

The bridge spans the Tresfjord between the towns of Vestnes and Vikebukt. The superstructure of the main bridge with a maximum span of 160 meters was built from two pillars using the cantilever method. The two approach bridges are built on a feed scaffold with a standard span of 60 meters. Longitudinal prestress

The remaining part of the building will be driven under by the new DB Nordkopf tunnel. In order to be able to produce the tunnel section, the building had to be underpinned on around 50% of its area. The support was carried out with the help of a prestressed 1.35 m thick, point-supported reinforced concrete slab. Client: DB Netz AG Executing construction company: Ed. […]

The construction of the Unstruttal bridge was built according to the latest state of engineering. The roadway runs on jointless and bearingless reinforced concrete girders lying one behind the other. At their ends, the temperature deformation is recorded by special devices. In a former open-cast mine, the soil had to be dynamically compacted. The roadway girders were built […]

In the course of the six-lane expansion of the A3 Frankfurt - Nuremberg motorway, a new building was necessary due to considerable damage to the Main Bridge near Würzburg-Randersacker. Construction work on the new bridge began in July 2007. First of all, the superstructure for the carriageway towards Frankfurt was built next to the old bridge, and this was completed at the […]
