China Development Network News On May 10, China Railway Construction made a stunning appearance at the 2024 China Brand Day with the underground space brand, and held a five-day exhibition at the Shanghai World Expo Complex.
Underground space, known as the "fourth land" beyond the land, sea and sky, is a new space carrier for urban development, as an organic part of land resources, is an important strategic resource, and has great development potential and value.
In the China Railway Construction Underground Space Brand Pavilion, through glasses-free 3D, light and shadow elevators and other technologies, the concept of underground space is popularized to the public, and the core technology and important achievements of China Railway Construction Underground Space Development are displayed. It provides a one-stop solution for the whole industry chain for China to develop the underground "fourth land" and expand the urban development space.
Theoretically, people call the area between 0-50 meters underground as shallow underground space, and most of the subways, underground shopping malls, and urban pipelines are concentrated in this area, carrying important functions of the city. More than 50 meters, the underground space has mineral development, energy storage, solid waste treatment and other applications, and also plays an important role in national defense and scientific research.
From science fiction to popular science! The "Wandering Earth" has become a reality
"Underground space, safety, and resources have risen to a national strategy, and deep urban underground space is a strategic choice for the country's new urbanization and sustainable urban development, and an important support for the national strategic security space." Dai Hegen, Secretary of the Party Committee and Chairman of China Railway Construction, said.
In the movie "The Wandering Earth", humans live in dungeons. China Railway Construction is the main force in the development of underground space, up to now, more than 40% of the tunnels and underground projects in the mainland have been built, the project has covered seven areas such as urban underground transportation space, municipal space, public service space, etc., and basically realized the science fiction scene in the movie.
At 32 meters underground, 3 subway lines, 2 underpass tunnels, and 1 underground ring road are interlaced here, and the Optics Valley Plaza Complex, Asia's largest transportation complex, developed by the Fourth Institute of China Railway Construction and Railway, integrates transportation, commerce, culture and entertainment, and efficiently connects the ground and underground, and skillfully combines art and use, providing a demonstration for the construction of future urban transportation hubs.
In Shanghai, the 15th Bureau of China Railway Construction is maneuvering the world's largest shaft boring machine, the Dream, to 52 meters underground. This is a modern smart garage integrating equipment, operation, monitoring, maintenance and management intelligence, with 304 parking spaces only need to be reached with one key by mobile phone, and the average parking time is only 90 seconds.
The formation of underground road networks has accelerated, changing the pattern of urban development. At a depth of 100 meters under the sea, the world's deepest submarine high-speed rail tunnel is being built with the participation of the 14th Bureau of China Railway Construction and China Railway Construction Co., Ltd.
A number of key underground projects have accelerated the "future dungeon" into reality, and also provided strong support for the underground space brand of China Railway Construction. A number of key core technologies and batches of high-end innovative equipment also provide services for deeper underground space development.
Cultivating new quality productivity! China has mastered the core technology of underground space development
"China Railway Construction will deploy the innovation chain around the industrial chain, lay out the industrial chain around the innovation chain, jointly expand the application scenarios and industrialization paths of scientific research achievements, and enhance the whole industrial chain of underground space utilization, diversified comprehensive service capabilities and core competitiveness." Wang Lixin, President and Deputy Secretary of the Party Committee of China Railway Construction, said.
For more than 70 years, China Railway Construction has overcome all kinds of complex geological environments, accelerated the development of underground space scientific and technological innovation, and reserved key technologies through the integration of the whole industrial chain, and is accelerating the cultivation and formation of new qualitative productivity for China's underground space development, and has embarked on an innovation-driven development path.
Fine detection of deep earth scanning, intelligent design of one-stop customized solutions, and intelligent operation and maintenance of holographic perception operation...... China Railway Construction can not only do CT scans of the earth and generate underground space solutions with one click, but also effectively improve the disaster prevention capacity of urban underground space with the help of deep space intelligent disaster prevention and mitigation methods and shield tunnel structural resilience improvement technology.
China Railway Construction not only exhibited the core competitiveness of shield construction, but also exhibited the most advanced tunnel intelligent construction technology in China. The cutterhead intelligent welding robot that has been put into use can greatly reduce labor costs and improve work efficiency, and the first super-large diameter shield synchronous double-liquid slurry grouting technology in China can effectively control the formation settlement and make the tunnel construction more stable, and the research and development of socket segments according to the traditional Chinese mortise and tenon joint technology also makes the tunnel construction more efficient and safe.
Jinghua, the first 16-meter-class super-large diameter shield machine in China, the world's largest diameter shaft boring machine Dream, and the world's largest diameter shield integral main bearing...... China Railway Construction has built the world's largest intelligent manufacturing base for high-end underground engineering equipment, and is committed to solving all kinds of "difficult and miscellaneous diseases" of underground engineering.
In addition, China Railway Construction has also cultivated a team of high-level talents led by academicians of the Chinese Academy of Engineering and national survey and design masters, with patents accounting for nearly 50% of the total number of patents related to construction central enterprises, and more than 50 national science and technology awards and 6 patent gold and silver awards.
At present, China Railway Construction has formed a whole-process underground space development plan of "intelligent design and operation and maintenance, intelligent construction and construction, and super equipment manufacturing" around the deep and special underground space projects of the city and the utilization of existing underground space.
There is more than one side of the world, building a beautiful underground space in the future
In the future, CRCC will actively respond to the national strategy, focus on establishing a new model of urban underground three-dimensional development, create a world brand, and become the leader of the shallow development of urban underground space below 50 meters, the technology leader of 50 meters deep, and the main researcher and participant of underground space with a depth of 50 meters.
To explore the underground space, China Railway Construction will also join hands with the fields of energy, environment and biology to bring the sun, moon and stars, gentle wind and drizzle, birds and flowers to the underground through natural light source simulation, underground ecological circle construction and human settlements environment control technology, so as to create a green ecological home where man and nature coexist in harmony.
China Railway Construction Underground Space Brand Highlights
