NFM Technologies has been awarded contracts totalling US$25.2M to supply two TBMs for the Yintao water diversion project at Tahoe river in China.
The 5.75m hard rock shields have been ordered by China Railway Tunnel Group Co (CRTGC) and Chinese-Italian joint venture of CMC Ravena and Synhydro Engineering Bureau.
CRTGC has order a single shield machine (named “T7”) and the JV a telescopic shield (“T9”), and NFM said in February that the TBMs are to be delivered within 11 months. They are to drive tunnels of 17.2km and 18.2km, respectively.
NFM said it has sold 15 machines in China in the last year and a half, and its order book stands at US$205M.
Tahoe river is a tributary of the Yangtze and the diversion project is to convey water to Gansu province in north west China. The Yintao scheme started in 2006 and the TBMs will work on the first of two, six-year long project phases.
