Underground—EMEA—Austria—Tunneling
All of the excavation work is being carried
out using conventional blasting; the only
exception is the surge shaft, where a shaft is
first being constructed using the raise boring
method.
For the construction of the different
tunnels and the excavation of the caverns,
DSI Underground Austria produced and
supplied the complete range of required
ground support products.
This mainly included OMEGA-BOLT ®
Expandable Friction Bolts, SN Anchors,
the DYWI ® Drill Hollow Bar Anchor System,
BST 550 steel spiles, lagging sheets,
PANTEX 3-bar Lattice Girders and
57.5mm Ø GEWI ® Bars.
