In June 5438+February 2009, China Railway Corporation integrated and reorganized the shield processing and manufacturing resources of China railway system. Based on China Railway Tunnel Equipment Manufacturing Co., Ltd., China Railway Tunnel Equipment Manufacturing Co., Ltd., jointly funded by China Railway Holdings and China Railway Tunnel Group, was incorporated in Zhengzhou Economic and Technological Development Zone and became a specialized tunnel equipment manufacturing company under China Railway Group, integrating R&D, manufacturing, assembly and commissioning, marketing leasing and after-sales service. Up to now, the investment in scientific research has exceeded 200 million yuan, with a total investment of 654.38+0.07 billion yuan; Accumulated 15 national utility model patents and 5 invention patents, and successively won 10 provincial and ministerial honors.
China Railway Tunnel Equipment Manufacturing Co., Ltd. has inherited the fruitful achievements of the development of China Railway shield industry and also undertaken the mission of the development of China Railway shield industry. The company has successively won the honorary titles of National High-tech Enterprise, National Key Brand Cultivation Enterprise of Ministry of Industry and Information Technology, Henan Shield Tunnel Technology Engineering Research Center, Top Ten High-tech Enterprises with the Most Investment Value in Henan Province, Zhengzhou University Graduates Employment Training Base, Zhengzhou University Postgraduate Innovation Practice Base, and Excellent Enterprise of Zhengzhou Economic and Technological Development Zone.
On the basis of digesting and absorbing foreign advanced technology, the company and its predecessor enterprises have successively undertaken five national scientific research projects and obtained special funds of 3 1 10,000 yuan, closely relying on the national "863" plan. June 5438 +20071October, the national "863" plan "Tunnel Boring Machine Laboratory" was unveiled in Xinxiang Shield Base of China Railway. At the end of the same year, the tunnel boring machine with independent intellectual property rights, the largest diameter in China and the most control points was successfully developed.
The most perfect simulation test platform of shield control system has been put into use; In April 2008, the first composite EPB shield with independent intellectual property rights in China was successfully manufactured and applied to the construction of Tianjin subway, and the industrial test was successfully completed in June 2009. In July of that year, through the appraisal of the "863" plan scientific and technological achievements expert group, the performance of the whole machine reached the international advanced level, and many key technologies reached the international leading level. The successful development of composite EPB shield fills the "blank" in this field in China, which is an important milestone in the development history of shield in China and also marks a major breakthrough in the industrialization of shield in China. Lead the shield era and carefully build the brand of China Railway Shield. China Railway Tunnel Equipment Manufacturing Co., Ltd. will adhere to the enterprise policy of "professional manufacturing and professional service", carry forward the enterprise spirit of "courage to leap forward and pursue Excellence" and March towards a more brilliant tomorrow!
