BUFFALO STAMPEDES TO MEET NATM CHALLENGE

The shotcreting element in the New Austrian Tunneling Method (NATM) is often the bottleneck in the cycle. The increasing use of the NATM as a rapid excavation technique has highlighted the need for specifically designed higher capacity shotcreting equipment. One company dedicated to the research and development of such equipment is Putzmeister of West Germany. The latest addition to its range of shotcreting equipment is the Spritzbuffel or Spray Buffalo, which is designed specifically for use on the construction of large cross section tunnels. The unit only handles wet concrete. The consortium Hochtief/Universale Bau is currently operating three of these machines on separate tunnel contracts on the new Hannover to Wuerzburg high speed railway.
