On the morning of August 7, China's first tunnel boring machine for the super large diameter submarine tunnel in 8 degree earthquake intensity area successfully rolled off the production line in Guangzhou, which marked that the construction of Shantou Bay Tunnel Project would be about to enter the most core and critical water section of the tunnel construction.

Shantou Bay Tunnel Project is China's first super large diameter submarine shield highway tunnel built in 8 degree earthquake intensity area, with such characteristics as complex geology, highly difficult construction and high-level safety risk. In order to ensure the reliability, advance and stability of the tunnel boring machine, China Railway Tunnel Group, the builder of the Project, conducted global procurement bidding. German Herrenknecht AG, the world's leading manufacturer of tunnelling equipment, won the bidding for manufacturing eastern front tunnel boring machine, which was especially tailor-made for Shantou Bay Tunnel. It took only 13 months for the design, manufacturing and factory assembly commissioning results of the tunnel boring machine, with a total construction cost of nearly RMB 400 million.
