The Herrenknecht team presents the tunnel boring machine to representatives of Wiener Linien, the client, and the construction consortium of Strabag and Porr. The EPB Shield for the extension of the subway line 2 in Vienna will excavate two 2.1 kilometer tunnels
The TBM for the Austrian capital has a diameter of 6,84 m, a length of around 120 m and weighs a total of around 1200 tons. The drive will start at the future Matzleinsdorfer Platz station, from where the machine will drive 2.1 km of tunnel northwards to below Augustinplatz. The machine will then be pulled back through the bored tunnel, which is lined with precast concrete segments, in order to drive the parallel tube from Matzleinsdorfer Platz.
With the expansion of the metro network, the city of Vienna is responding to a rising population. More than two million people are expected to live in the capital by 2030. According to the city, the investment in the line extensions will create and secure around 30 000 jobs.
