China Railway Engineering Co., Ltd., a subsidiary of China Railway Engineering Corporation, is the first high-tech enterprise in Henan Province, and the highest level of mechanization of tunnels and underground construction in China. The committee is affiliated with the company.
In 2003, China Railway Tunnel Co., Ltd. established the National “863†Plan Scientific Research Center, Tunnel Boring Machine (TBM, Shield) Manufacturing Center and Assembly and Commissioning Center in Xinxiang City. He has undertaken two tasks in the theme of "National "863" Program "Robot Technology in Advanced Manufacturing and Automation Technology". In the past two years, the technical design of the 6.3-meter-diameter shield machine and the research on tool-cutter design and hydraulic drive system have been completed. In 2004, the work of Shanghai Metro Line 2 was successfully completed. We have successively designed a shield machine, co-manufactured a shield machine and a TBM, and completed the factory assembly of two equipments. These equipments operate normally in the Guangzhou Metro No. 4 Xiaoxin Section and the Liaoning Dahufang Water Transfer Project. In addition, the company's self-developed TBM and shield construction series of supporting products, widely used in urban subway and tunnel construction. Six of the results have obtained national patents.
In July 2005, the company was approved by the expert group of the Ministry of Science and Technology, and the company was also allowed to undertake the task of developing the “10th Five-Year†continuation project and the “Eleventh Five-Year Plan†project for the national “863†plan shield. Liu Weining, executive member of the International Tunnel Association and a professor at Beijing Jiaotong University, believes that a series of major breakthroughs in the research and development of domestic tunnel boring machines will further enhance the industrialization level and construction mechanization level of tunnels and underground projects in China. Wang Mengshu, academician of the Chinese Academy of Engineering, Guo Shanyun, chairman of the Tunnel and Underground Engineering Branch of the China Civil Engineering Society, Liu Chun, former deputy chief engineer of the China Railway Engineering Corporation, and Wang Jianyu, former dean of the China Railway Southwest Research Institute, and other authorities in the field of tunnels and underground engineering Experts fully affirmed the company's achievements in the research and development of domestic tunnel boring machines.
At present, China's domestic tunnel boring machine research and development has made a major breakthrough
Recently, the reporter learned from the first Science and Technology Conference of China Railway Tunnel Co., Ltd.: China Railway Tunnel Co., Ltd. and Zhejiang University, Henan University of Science and Technology and other scientific research institutes jointly undertake the national "863" plan - the domestic full-section tunnel boring machine A major breakthrough was made in research and development.
