THE HEITERSBERG TUNNEL

The author reports in detail on boring a 2600 M long 10.67 M diameter railway tunnel through sandstone, silt and marl. Precast concrete segments were placed in the tunnel invert immediately behind the cutter head, and a first concrete lining was applied to the rest of the circumference of the tunnel using an automatic concrete spraying machine following a very short distance behind the boring machine. Daily advance in a 2 shift day was 8 M, using roof-bolts and wire mesh reinforcement, or 3.6 M in the quarter of the tunnel length where steel rib support was used. The number of the covering abstract of the conference is IRRD 231024.
