尼克斯vs湖人录像 www.uniuiz.net A China-made balanced slurry shield machine with the largest operating diameter in the country was put in use at the construction site of the Chunfeng Tunnel in Shenzhen on Aug 13.
The machine, 135 meters long, can dig a tunnel with a diameter of 15.8 meters.
The shield machine is expected to play an important role in ensuring the tunnel can be finished and opened to traffic by 2021.
The tunnel project is about 5.08 kilometers long, and connects Binhe Street in the west and the Xinxiu Crossover in the south. It generally follows the line of Chunfeng Road.
After the tunnel is opened to use, the traffic capacity between the two points will be twice the previous level, effectively resolving traffic congestion in the south of Luohu district.
