After an extensive amount of research and testing CREG has developed the world's first U-sharp EPB machine for application in soft ground conditions. The Menghua U-sharp EPB TBM created by CREG has successfully completed the first 500m of the 3,345 m Baicheng railway tunnel, located in Shanxi Province. The tunnel is in being constructed in Quaternary alluvium (silty fine sand and yellowish clay).
The TBM was launched in November 2016 and after a period of adaptation achieved a high level of productivity producing five rings per shift. For further information please read their press release or visit their website http://creg-germany.com. 04/17.
