Strand Anchors stabilize Excavations

Project Approval Section 1.5 is part of a Stuttgart 21 sub-project – the railway project Stuttgart-Ulm. 1.5km of the new section are being built using the open cut method, and the new suburban train station is also located in a trough. The different excavations in Lot 4 North were stabilized using DYWIDAG Strand Anchors.


Project Approval Section 1.5 refers to the triangle between the train station in Feuerbach, the train station in Bad Cannstatt and the access to Stuttgart Main Station. This section includes the planned, approximately 9km long underground long-distance rail and suburban train tracks to Feuerbach, Stuttgart-Nord and Bad Cannstatt.

In Lot 4 of this section, the new district that is being created by eliminating the existing above ground tracks in the north of the main station is being connected to public transport. For this purpose, a new station is being built for all suburban trains in the new district Rosensteinquartier at Mittnacht Street.


At the area UL 7 at the Mittnacht Street Station, the excavation was stabilized using approximately 13,000m of temporary, grouted 3 to 5 strand DYWIDAG Strand Anchors.

At the branch-off construction in area UL 8, approximately 9,000m of temporary and permanent 3 to 5 strand anchors were installed.

For area UL 10, DYWIDAG also supplied approximately 18,000m of temporary and permanent, 3 to 5 strand grouted DYWIDAG Strand Anchors.
