An Iseki Unclemole was lowered into a shaft in Barry, Wales, early last month to construct part of a new flood sewer. The TBM is being used in this section of the project by Morgan Est to install a 147m long stretch of 1.5m i.d. pipeline tunnel for client Welsh Water, which is investing in flood alleviation infrastructure in a £130M (US$218M), five-year programme.
