On April 8th morning, along with a "rumble" roar, NHI "Cooperation 2" Tunnel Boring Machine (TBM for short) started tunneling at the 17m underground construction site of Culture West Road Station of metro line 10. Compared with other TBM, this TBM made by NHI is more humane with reasonable spatial distribution and its cutter parameters are more suitable for Shenyang soil. "Cooperation 2" TBM complete the installation of 20 ring segments within 24 hours.
