SELECTIVE CUTTING MACHINES FOR USE WITH THE NATM

High growth rates in tunnel construction are expected in the German Federal Republic due to increasing traffic volumes, the improvement in supply and disposal utilities, and the increasing obligation for environmental protection. From 1980 to 1985 some 1700 km of utility supply and disposal tunnels, and also 120 km of railway traffic tunnels, are to be constructed. A review of the circumstances which apply to conditions and requirements for tunnelling in the German Federal Republic indicates that selective cutting machines, which in contrast to full-face cutting machines, cut only parts of the working face, offer advantages of cost, adaptability and versatility. The article describes in detail the equipment employed in such tunnelling projects where excavation techniques are influenced by principles of the New Austrian Tunnelling Method (NATM). (TRRL)
