Liu Feixiang: Systematically Promoting the Autonomy and Industrialization of Underground Engineering Equipment
October 11, 2023
Breakthrough and Transcendence of a Technology，Upgrading and leading of an industry，You need to dare to face the wall、Hit a wall，The light chaser who clings to the broken wall。The underground engineering equipment industry is like this.。
Liu Feixiang, chief scientist of China Railway Construction Heavy Industry Group Co., Ltd., is a systematic study of underground engineering equipment in China and promotes the realization of industrial autonomy.、Pioneers of industrialization，He has been fighting for a long time in the front line of scientific research and engineering technology.，Breakthrough series“Stuck in the neck”Key technologies，Developed shaft and inclined shaft Roadheader with completely independent intellectual property rights、Intelligent equipment for drilling and blasting and non-blasting tunnel、Shield Machine andTBMAnd other heavy weapons of great powers，It meets the needs of more than 100 major projects in China's economic and social fields.，It is also exported in batches to many countries and regions.，Cumulative through tunnel（Hole/The well）Thousands of kilometers。
For energy、Major engineering needs in nuclear industry and other fields，Liu Feixiang presided over the breakthrough of efficient rock breaking in vertical and oblique full-face tunneling.、Slag is discharged upwards、Pose control and other international technical problems，Developed the world's largest diameter of 23 meters full-face shaft Boring Machine、The world's first spiral inclined shaft Boring Machine“Beishan No.1”、The world's first variable diameter large climbing（≥50°）Inclined shaft Boring Machine“Tianyue”Wait for the first set of shaft/Inclined shaft boring machine，The overall technology of China's shaft and inclined shaft Roadheader is leading the world.。
For water conservancy projects、Construction needs of river-crossing and sea-crossing tunnels and other projects，Liu Feixiang takes the lead in breaking through hard rock、The card machine gets out of trouble、Attitude correction core technology，Developed the first domestic machineTBM，Research and development of the first domesticTBM“Changchun”、Xinjiang Water Diversion ProjectTBMFleet, etc，Successfully crossing extremely hard rock，Achieve rapid release of stuck machine in broken strata。He took the lead in breaking through the high-pressure seal.、Normal pressure tool change、Key technology of settlement control，Developed a domestic maximum diameter of 16.07 meters“Jinghua”、Deepest undersea tunnel Shield Machine in China“Shenjiang No.1”Iso-large diameter slurry balance Shield Machine，Realize that the tool changing time is greatly shortened、The ground surface settlement is controlled at millimeter level.。He presided over the development of a series of achievements to lead domestic production.TBMAnd large-diameter shield machine are leading in the world.。
For railways、Highway and other mountain tunnel engineering construction needs，Liu Feixiang led the breakthrough of tunnel equipment.“Subterranean perception、Ground analysis、Cloud decision making、Equipment execution”Digital and intelligent technical problems，Developed the world's first full-process drilling and blasting tunnel intelligent equipment fleet and digital intelligent management system，The products are widely used in Zhengzhou-Chongqing high-speed railway.、Expressway along the Yangtze River、Major projects such as hard beam package hydropower station，Compare with that traditional method，50% improvement in construction efficiency%、Personnel decreased by 64%，It has created a new mode of construction of unmanned tunnels with fewer people.。
Aiming at the requirements of safe and efficient construction of coal mine engineering，Liu Feixiang put forward the optimization method of pick group arrangement.，Initiated“Detective-Dig-Branch-Yun”Full-process efficient cooperative operation technology，Developed the world's first large-section intelligent complete set of equipment for rapid excavation and anchoring，Successfully excavated the world's first super-large section roadway of over 40 square meters，5x more efficient、Monthly footage breaks through 1750 meters，Promote the formation to adapt to different section sizes、Different geological conditions、Coal mine tunneling full working condition and full scene construction application machine group with different regional requirements，It has promoted the scientific and technological progress of high-end mining equipment and the rapid development of mine intelligent construction in China.。
Liu Feixiang was awarded the National Labor Model、Model of central enterprises、Hunan Guangzhao Science and Technology Award、The most beautiful scientific and technological workers in Hunan、Honors such as high-end talents of Hunan Lifting Project。
