The Herrenknecht tunnel boring machine, specifically the EPB Shield (Earth Pressure Balance Shield) unit was ordered by the Austrian tunnel building experts. The expansion of subway line 2 from Vienna City Hall to the south is being built by STRABAG and PORR in joint venture for Wiener Linien, the operator of the Vienna subway.<\/p>\n
\u201cThe Herrenknecht EPB Shield is the optimal machine type for the predominantly clayey geology that we expect according to the preliminary investigations,\u201d stated Ralph Lickert, Project Manager at Herrenknecht.<\/p>\n
The Herrenknecht EPB Shield for the Austrian capital measures 6,840 mm in diameter, 120 m in length, and weighs 1,200 tons in total. The machine will begin at the upcoming Matzleinsdorfer Platz station and travel 2.1 kilometers northward through a tunnel beneath Augustinplatz. After that, the Herrenknecht tunnel boring machine will be dragged back down the precast concrete-lined bored tunnel to drive the parallel tube from Matzleinsdorfer Platz.<\/p>\n
