Train tunnel Pannerdensch canal, Betuwe line, The Netherlands
A drilled tunnel underneath the Pannerdensch canal between the towns Bemmel and Zevenaar is a train tunnel, which was built by an unique building method. A special bore machine was used to drill two, 1600m long, adjacent tunnels for the trains. The total length of the tunnel is 2680m. The lining of the tunnel with internal diameter 8,65m is made up from concrete rings comprising seven segments complemented with a keystone. The tunnel was built between 1999-2004.
FDN was asked by Arcadis to design a caisson for the bore machine and to check project documentation regarding all calculations of the concrete structures.
