Adhering to the corporate philosophy of "big industry, big school, big family and big stage", China Railway Tunnel adheres to the people-oriented principle and has gathered a large number of outstanding engineering and management talents in China. At present, the Group has more than 50,000 employees 1.5, more than 7000 professional technicians and more than 7000 skilled workers, including China Academy of Engineering 1, national survey and design master 1, 5 national experts with outstanding contributions, 2 1 personnel enjoying special government allowance from the State Council, and qualified project managers (.
China Railway Tunnel closely follows the development trend of international construction technology, comprehensively promotes the modernization of construction production, and its technical equipment level is in the leading position in China. At the end of 2006, the design and manufacture of simulation test platform for slurry shield control system were completed. It is the largest physical simulation test platform with independent intellectual property rights in China, which has great influence on the localization and application of shield in China.
In April 2008, China's first composite earth pressure balance shield with independent intellectual property rights was successfully developed, which filled the gap in the field of composite shield in China and was an important milestone in the history of shield development, ending the history that China relied on foreign shields for tunnel construction in complex geological environment. China Railway Tunnel has more than 4,000 sets of large and medium-sized mechanical equipment, and 40 sets of TBM and shield machines. It is the construction enterprise with the most complete variety and the largest number of TBM and shield machines in China, occupying an absolute leading position in tunnel and underground engineering construction, equipment research and development and equipment capacity, with an annual tunnel construction capacity of more than 400 kilometers.
China Railway Tunnel is vigorously promoting the industrialization of roadheader, and is building a large-scale and technologically advanced roadheader design and manufacturing base with subway shield as the main part, forming a complete roadheader industrial chain. It is planned to achieve an annual production capacity of 20 tunnelling machines in 20 10, when the domestic market share of China Railway Tunnel Boring Machines will reach 10%.
