1978, bathed in the spring breeze of China's reform and opening up, with the approval of the State Council, the Ministry of Railways established the Tunnel Engineering Bureau. Since then, China has a specialized enterprise specializing in tunnel and underground engineering construction. 200 1, the Tunnel Engineering Bureau was successfully restructured into China Railway Tunnel Group. Since its birth, China Railway Tunnel Group has shouldered the sacred duty and solemn mission of "being loyal to the country and contributing to the society", and demonstrated extraordinary professional quality in the field of tunnels and underground engineering in China. The Dayaoshan Tunnel with a total length of 14.295km was completed in one fell swoop, ending the history that China people could not independently build long tunnels with a length exceeding 10km. Relying on the professional advantages of "design, scientific research, construction and manufacturing", China Railway Tunnel has participated in the construction of long tunnels under almost all complicated geological conditions in China, and has created a new era of tunnel construction in China again and again, forming a series of tunnels and underground engineering construction technologies with independent intellectual property rights, especially since 2007. Dayaoshan Tunnel on Wuhan-Guangzhou Passenger Dedicated Line, Shiziyang Tunnel on Guangzhou-Shenzhen-Hong Kong Railway, Shijiazhuang Tunnel on Beijing-Shijiazhuang High-speed Railway, lanzhou-chongqing railway West Qinling Tunnel, Beijing Railway Underground Diameter Line, Wuhan Yangtze River Tunnel, Xiamen East Passage Xiang 'an Tunnel, Qingdao Jiaozhou Bay Tunnel, Hangzhou Chun Qing River Crossing Tunnel, Guangzhou Bio-Island Immersed Tube Tunnel, Shiziyang Tunnel on Guangzhou-Shenzhen Passenger Dedicated Line, Wuhan Metro River Crossing Tunnel, A large number of new high-rise and large-scale tunnel projects, such as Liuyang River Tunnel in Changsha, have made a series of scientific research achievements in soft and complex geological tunnel construction technology, key technology and supporting equipment of railway passenger dedicated line, selection and construction technology of supporting equipment of shield machine, mechanization of long and long tunnel construction and tunnel construction technology in special environment. 35 1 scientific research achievements have passed the evaluation, appraisal and acceptance of higher authorities, and won 8 1 scientific and technological progress awards at or above the provincial and ministerial levels and 28 national patents. He has won 52 awards, including Luban Award, National Quality Engineering Award, Zhan Tianyou Civil Engineering Award, National Science and Technology Progress Award and Excellent Survey and Design Award, and compiled national and industry standards 2 1 item. From June 5, 2008 to February 2008, our group company was recognized as a high-tech enterprise in Henan Province. On June 20 10, it was successfully declared to the state key laboratory of shield and tunnel technology, and on June 20 1 10, the enterprise technology center was successfully recognized as a national technology center. At present, the number and types of shield machines we have rank first in China, and the annual tunnel construction capacity reaches more than 500 kilometers. It has led five leaps in the construction of tunnels and underground projects in China and made positive contributions to the construction of tunnels and underground projects in the motherland.

As a professional backbone member of China Railway Corporation, a world enterprise and a top 500 brand in the world, China Railway Tunnel Group will adhere to the enterprise spirit of "sincerity to beauty, perfection to new" and take "doing the best and paying the best" as its enterprise purpose to lead the development of China tunnels and underground projects, improve the core competitiveness of enterprises and maintain its unique competitive advantage; Further explore the establishment of an industrial chain for the coordinated development of upstream, downstream and downstream enterprises, develop new economic growth points and profit growth points, enhance the industry influence of enterprises in the field of tunnels and underground engineering, improve the brand awareness of "China Railway Tunnel", and make the company a "domestic leading, world-famous" and internationally competitive modern enterprise.
