According to reports, the "Tianhe 1" excavation diameter of 15 meters, almost all of the world's cutting-edge technology for the production of shield machine, can meet the geological conditions of quartz sand containing high levels of pebbles, rock strength up to 120 MPa The construction requirements for the composite stratum of the Yangtze River, clay, are tailor-made for Nanjing Weisan Road Cross-river Tunnel Project.
Previously, large shield machines that could adapt to this complex soil condition all depended on imports. "Tianhe 1" is China's first large muddy water pressure balanced compound tunnel boring machine with independent intellectual property rights, and its successful development fills the gap in the field in China.
The largest "Tianhe I" tunnel boring machine passed the acceptance
The "Tianhe 1" tunnel boring machine developed by Zhongjiao Tianhe Machinery Equipment Manufacturing Co., Ltd. was formally accepted and handed over. It will soon be put into the construction of Weisan Road in Nanjing over the Yangtze River Tunnel. This is the world's largest muddy pressure balanced tunnel boring machine.
