Kawasaki TBM

Construction of the Channel Tunnel Rail Link entered a new phase last month when the cutter head of the first Kawasaki TBM was lifted into position at the western end of the Stratford International Station box in east London.

The machine will drive one of the 7.5km twin tunnels connecting Stratford to St Pancras station in north London. Contractor Nishimatsu-Cementation Skanska joint venture used a 1500t capacity crane to lift the three separate parts of the cutter head, each weighing more than 200t into position.

As GE went to press, the second TBM's cutter head was due to arrive by ship from Teesside, where it was assembled and commissioned (GE August 02).
