DYWIDAG Strand Anchors stabilize Excavations for Project Approval
Section 1.5, Lot 4 North, Stuttgart 21
Project Approval Section 1.5 is part of a Stuttgart 21 sub-project – the railway project Stuttgart-Ulm – and 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.
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.
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, DSI Construction Germany
also supplied approximately 18,000m of
temporary and permanent, 3 to 5 strand
grouted DYWIDAG Strand Anchors.
