1. Large Shield and Underground Space Science and Technology Development Research Institute (referred to as "Large Shield Research Institute") is headquartered in Nanjing and is affiliated to China Railway 14th Bureau Group Co., Ltd. It mainly carries out large shield and underground research and development. Space-related technological innovation and technical service businesses. The Large Shield Research Institute has a Shield Intelligence Research Institute, a Shield Machinery Research Institute, a Standard Process Research Institute, an Underground Space/TBM Research Institute, and has academician workstations, postdoctoral workstations, expert studios and other research and development institutions. It is the first in China. Large shield professional research institution.
2. Underwater and ultra-large diameter shield construction technology is the core competitiveness that China Railway 14th Bureau Group strives to build. After nearly two decades of high-quality and efficient development, it has initially laid the foundation for domestic ultra-large diameter and underwater shield construction technology. A leader in the field of shield tunnel engineering. It has contracted the construction of the first tunnel of the Yangtze River - the Nanjing Yangtze River Tunnel, the first corridor of the Yangtze River - Sutong GIL UHV Integrated Pipe Gallery, the first tunnel of the smart high-speed railway - the Qinghuayuan Tunnel of the Beijing-Zhangjiakou High-speed Railway, and the first tunnel of the Yellow River - the first tunnel of the Yangtze River. —Jinan Yellow River Tunnel, China’s first submarine shield tunnel—Xiamen Metro Cross-Sea Tunnel, Yangzhou Slender West Lake Tunnel, Beijing East Sixth Ring Tunnel, Beijing-Shenyang Passenger Railway Wangjing Tunnel, Nanjing Heyan Road Cross-River Tunnel, Guangzhou Haizhuwan Tunnel, A large number of benchmark projects with major technical and industry influence, such as the Shantou-Shantou Railway Undersea Tunnel. Currently, there are 133 large shield tunnel projects under construction or completed nationwide, including 43 projects of the 14th Bureau, accounting for 32%; 73 large shield tunnels (with a diameter of more than 10 meters) are under construction nationwide, and 32 projects of the 14th Bureau. than 44, ranking first in the country.
3. Relying on major and difficult projects under construction, as well as major scientific research projects such as the National 863 Plan, scientific and technological support, and key R&D plans, the Large Shield Research Institute has carried out more than 80 scientific and technological development projects, and has been awarded national More than 230 authorized patents, 18 software copyrights, won 1 National Technology Invention Award, 2 National Science and Technology Progress Awards, 3 National Quality Engineering Gold Awards, 4 Luban Awards, 3 Zhan Tianyou Civil Engineering Awards, provincial and ministerial level science and technology awards 18 Progress Awards.
