On October 22, the large diameter (9.53m) ultra-small turning rock tunnel boring machine 'Funing' which is jointly developed by CREG and Sinohydro Bureau 11 was successfully launched. 'Funing' takes responsibility of boring 1030m for the traffic cave and ventilation cave of the power station. The total length of “Funing” is 85m with a minimum design turning radius of 90m, a maximum design longitudinal slope of 10%, which is extremely flexible in construction. Comparing to traditional blasting, it has the characteristics of fast construction speed, safety and environmental protection, low labour demand, high automation, no blasting vibration and reduced over-excavation to save lining costs.
