In at the deep end - Part two

摘要

Continuing from the January issue, Maurice Jones reports on the tunnel boring progress, lining, cross-passage construction and surface facilities for the Westerscheldetunnel project.rnThe TBM for Westerschelde tunnel's west bore started work three months after that for the east bore, but ground problems there have resulted in it overtaking its twin. When T&TI visited the site at the end of October, the west bore TBM had progressed 2000m and the east bore 1600m. Current progress averages seven rings a day for both machines, or 14m, on a planned 6-day week, 24h a day.
