Large format panels for a smooth and jointless component surface
Situated on the new Erfurt - Leipzig/Halle route, construction of the Unstruttal Bridge near Karsdorf and Wetzendorf in the Federal State of Saxony-Anhalt began in 2007 and was completed in 2012. Measuring 2,668 metres in length, it is the second longest railway bridge in Germany.
The German infrastructure operator DB Netz AG, a subsidiary of Deutsche Bahn, commissioned the consortium of Alpine Bau Deutschland AG and Berger Bau GmbH to construct the semi-integral prestressed concrete box girder bridge in July 2007. Welded alkus® large format solid plastic panels were used for the formwork of the outer walls, the underside and the cantilever construction of the Unstruttal Bridge. The main reasons for choosing the alkus® formwork panel were its extensive service life compared to plywood panels and the desire for a smooth and jointless component surface.
alkus® reduces frequent re-panelling and the amount of release agent required
The use of alkus® panels was definitely worthwhile: Not once during the entire project did any of the panels need replacing – while they ensured the same high surface quality throughout. In fact, the panels were subsequently used in follow-up projects. The use of the alkus® solid plastic panel also meant that far less release agent was required.
