Lainzer Tunnel

neighbouring buildings, are particularly
solid for reasons of avoiding vibration
and structure-borne sound emissions.
Thus, the base plates have a thickness
of 1.80 m, the T-beams of the tunnel
ceiling have a height of 3.0 m and the
inner shell on the side towards the
neighbouring buildings has a thickness
of 1.20 m.
The line from the former train station
Unterhetzendorf up to the crossing of
Lainzer Tunnel 11
the U6 was built in a closed construction
method.
From the crossing of the U6 up to
Eibesbrunnergasse, the dig-and-cast
construction method was then used
again – using bored piles with a diameter
of 120 cm.
