Acceptance meeting site
The project was launched in 2019.,It is the first major provincial science and technology project in Hunan Province with a support fund of over 50 million yuan.,Led by Railway Construction Heavy Industry,United Central South University、Hunan University、National University of Defense Technology、Xiangtan University、Harbin Institute of Technology、Zhejiang University、Zhuzhou Cemented Carbide Group and other scientific research forces,Focus on the lack of complete sets of equipment faced by super underground engineering construction in China、Low degree of intelligence、Poor geological adaptability、To tackle outstanding problems such as long-term dependence on imports of main bearings and high-performance cutting tools in a coordinated manner。
After concentrated attack,The project team has conquered the synchronous technology of super-large section shaft cutter head design and rapid segment assembly.、High Precision Positioning of Geological Exploration Equipment and Stress Detection of Deep Rock Mass、Intelligent Support and Adaptive Cruise of Rock Tunnel Boring Machine、There are more than 10 key technologies such as self-perception of surrounding rock and intelligent management and control of fleet operation.,Independently developed the world's largest diameter(23m class)Full-face shaft Boring Machine、The First Domestic Kilometer Level Horizontal Drilling Equipment、The longest construction distance in domestic plateau area(20 kilometers)Full-face rock tunnel Boring Machine、Four kinds of special complete sets of equipment and high-performance long-life hob, such as 8 kinds of super-risk drilling and blasting tunnel intelligent complete sets of equipment、Two types of core basic parts of main bearing of Roadheader with various specifications。
During the special execution period,172 patents have been applied for.,96 papers published or accepted,Apply for 16 software copyrights,Formulating 16 enterprise standards,Relying on the relevant technical equipment developed by the special project, it has been successfully applied in more than 10 national key projects.,The industrial application effect is good。
The expert group led by Academician Gui Weihua visited the production workshop.
Academician of Chinese Academy of Engineering、Gui Weihua, head of the expert group, made a speech on the spot.
Zhu Wan, deputy director of Hunan Science and Technology Department, made a speech on the spot.
The expert group believes that,The special project has achieved outstanding results.,Overcome a number of international technical problems,Some of the equipment developed has filled the international gap.,Meet the requirements of plateau railway、Construction needs of major national projects such as the diversion of water from Liaoning Province to Liaoning Province,Seize the technological commanding heights of the global underground engineering equipment industry,Obvious economic and social benefits have been achieved;The special project has effectively solved the perception difficulty of underground engineering construction.、Excavation is difficult、Drilling is difficult、Difficulty in precise orientation and positioning、Slag tapping is difficult、Support is difficult、Cluster coordination is difficult、Intelligent control is difficult、The localization of key components is difficult.。
Person in charge of special project、Liu Feixiang, Chief Scientist of China Railway Construction Heavy Industry, On-site Report
Person in charge of special project、Liu Feixiang, chief scientist of Railway Construction Heavy Industry, said.,The independent development of intelligent complete sets of super underground engineering equipment has strongly promoted the technological progress of China's underground engineering equipment industry.,The development of a series of related supporting industries.,It has created a new superior industrial chain of super underground engineering intelligent equipment.,The new economic growth point of intelligent equipment for underground engineering has been cultivated.,Establish a world-class research and development base for super underground engineering equipment industry。
Secretary of the Party Committee of China Railway Construction Heavy Industry、Chairman、General Manager Zhao Hui made a speech on the spot
At the acceptance meeting,Secretary of the Party Committee of China Railway Construction Heavy Industry、Chairman、General Manager Zhao Hui thanked the Hunan Provincial Committee.、The provincial government、The Provincial Science and Technology Department has a high degree of trust and strong support for Railway Construction Heavy Industries.,Railway Construction Heavy Industry has been approved to undertake the largest provincial science and technology major project funded by special funds in Hunan Province so far.。Zhao Hui said,Since the start of the project,Project team led by Liu Feixiang, chief scientist,Through three years of hard work,A series of significant achievements have been made.,Overcome many items“Stuck in the neck”Key components,Seize the technological commanding heights of the global underground engineering equipment industry,In order to realize Hunan Province“Three high and four new”The beautiful blueprint has made outstanding contributions.,China's underground high-end engineering equipment has made a great contribution to leading the world in an all-round way.、A creative achievement。
