Anchor Bolt Applied for Railway Bridges

The rail line from Hannover to Bremerhaven is an important and heavily travelled line in northern Germany. On this route, two old railway bridges across the Aller River and the Waetern Stream near the town of Verden south-east of Bremen are replaced.
The bridges was built east of the existing bridge structures on a new, 2.1km long line. Vibro-replacement columns had to be installed in order to increase the load-bearing capacity of the soil in the embankment that was to be widened between the two bridges.
Within the scope of construction work, the existing embankment had to be stabilized along a length of approx. The 1,700m embankment using 21,200m of temporary R32 anchor bolt and steel wire mesh.
Since construction work was carried out in the flood zone of the Aller River, construction work had to be temporarily suspended in June 2013 due to flooding.
Nevertheless, the stabilization of the embankment was successfully completed thanks to the excellent co-operation of all parties involved.
