Small diameter Tunnel Boring Machine
The principle of ground excavation by TBM and consecutive ring building are well-known in the construction industry (mostly for large traffic tunnels). Within the small diameter tunnel range of up to 4000mm inner diameter, numerous projects have been executed worldwide using the segment lining method. It offers a high degree of flexibility concerning the planning of tunnel routes. Compared to pipe jacking, less shafts are required, long drives and tight curve alignments are possible.
