Guide: on October 24, the high-end Forum on shield technology innovation and shield industrialization was held in Zhengzhou, Henan Province. Wang Mengshu, Liang Wenhao, Zheng Yingren, Wang Jingquan, academicians of the Chinese Academy of engineering, Xiongyoulun, an academician of the Chinese Academy of Sciences, and experts from universities and enterprises gathered at the State Key Laboratory of shield and tunneling technology, Huashan lunjian

on October 24, the high-end forum on shield technology innovation and shield industrialization was held in Zhengzhou, Henan Province. Wang Mengshu, Liang Wenhao, Zheng Yingren, Wang Jingquan, academicians of the Chinese Academy of engineering, Xiong Youlun, academicians of the Chinese Academy of Sciences, and experts from universities and enterprises gathered in the National Key Laboratory of shield and tunneling technology to discuss various problems encountered in shield technology innovation and tunneling, It will provide technical reserves for the construction of extra long subsea tunnels in the future and provide suggestions for accelerating the industrialization of shield tunneling in China

at present, China has become the world's largest tunnel country, and the construction of urban rail transit has set off a new upsurge. Tunnel crossing rivers and oceans is rising. The development and construction of shield machine will be a huge market in the future. Therefore, Dr. hongkairong, director of the State Key Laboratory of shield and tunneling technology and chief engineer of China Railway Tunnel Group, was interviewed around the innovation and industrialization of shield technology

Hong Kairong said: "the advantage of the laboratory lies in the close combination of production, learning, research and application, mutual promotion and benign development. At present, gratifying achievements have been made, which has greatly improved the innovation ability of shield and tunneling technology."

in the mid-1990s, China Railway Tunnel Group took the lead in successfully building the Qinling Tunnel of Xikang railway with TBM. Since the beginning of the 21st century, they have successfully constructed the Yuesan section of Guangzhou Metro Line 2 by using composite shield, which marks the beginning of large-scale construction of urban subway by shield method

Hong Kairong said, "during the construction process, we found that the 'foreign shield' is often acclimatized and the accessories are expensive. It is in the process of overcoming difficulties again and again that we realize the importance and urgency of shield localization." However, the manufacturing process of shield machine is complex and has high added value. The technology only operates the experimental force control button. Through the microcomputer controlled automatic loading system, the loading at a fixed rate can be achieved, which is mastered and monopolized by a few developed countries abroad. "If we cannot realize the localization of shield, we will always be controlled by others."

with the strong support of the Ministry of science and technology and Henan Province, China Railway Tunnel Group Co., Ltd. has undertaken the research on the key technologies of shield tunneling in the National 863 plan since 2002. After more than seven years of efforts, it has independently designed and manufactured China's first composite earth pressure balance shield - "China Railway No. 1". Nowadays, the "China Railway" series of shield machines have played a major role in the national rail transit construction by virtue of their low failure rate, high control accuracy, reasonable cost and other advantages

at the beginning of 2010, the Ministry of science and technology officially approved the preparation of the State Key Laboratory of shield and tunneling technology based on China Railway Tunnel Group Co., Ltd. to undertake a number of national scientific research projects

in May 2011, the first 973 Program "basic research on digital design of shield cutterhead tools based on efficient rock breaking" undertaken by the key laboratory was launched

in December 2011, the second 973 Program "Research on shield electro-hydraulic measurement and control method and system integration technology" undertaken by the key laboratory passed the expert demonstration of the Ministry of science and technology

on April 26, 2012, the State Key Laboratory of shield and tunneling technology was unveiled in Zhengzhou National High tech Zone

introduction by Hong Kairong: the laboratory carried out relevant technical research around the geological adaptability of shield and the goal of rapid, safe and civilized shield tunneling, and determined three research areas: cutterhead and cutting tool technology, shield construction control technology, and system integration and control technology. 4 Experimental space (excluding piston stroke): 11000mm; In terms of research direction, 11 test systems, such as the comprehensive tool detection system, construction data processing and virtual reality technology, have been put into use, and a series of high-level exchange activities, such as the shield construction technology exchange across the Taiwan Strait, have been carried out, and important progress has been made in many aspects

"scientific research and construction are closely coordinated and mutually promoted." Hong Kairong said. At present, the research on remote fault diagnosis of shield tunneling has been launched, and the real-time transmission and analysis of shield construction operation data have been preliminarily realized. Pilot projects have been gradually carried out in Chongqing Rail Transit Line 6, Shenzhen Metro Line 11, Wuhan Metro river crossing tunnel and other projects, and remarkable results have been achieved
