Innovation leads China's high-speed rail "eight vertical and eight horizontal" has been built 70%
"Thirteenth Five-Year" Achievement Tour
On September 27th, the Quzhou-Ningde (Quning) railway opened for operation.
Under the autumn sun, the Fuxing was all the way to the west, connecting Suichang, Songyang, Longquan, Qingyuan in Zhejiang Province, as well as the eight counties and cities of Fujian Songxi, Zhenghe, Pingnan, and Zhouning that were previously unreachable.
At the end of 2015, the operating mileage of China's high-speed railways was 19,000 kilometers. Since the 13th Five-Year Plan, railway construction has progressed in a scientific and orderly manner.
It is estimated that by the end of 2020, the national railway operating mileage will be 145,000 kilometers and high-speed railways will be 38,000 kilometers, of which 45,000 kilometers of the "eight vertical and eight horizontal" high-speed rail main skeletons will be put into operation up to 33,000 kilometers.
According to the National Medium and Long-term Railway Network Plan released in 2016, the "eight vertical and eight horizontal" high-speed rail network will be completed by 2030. At present, the main network framework has been built 70%.
Adjacent large and medium cities arrive in 1-3 hours
At 0:00 on September 14, Jianyang, Sichuan.
The staff of the China Railway Construction Electrification Bureau Group began to change the overall catenary of the Chengdu-Chongqing high-speed rail, completing the transformation from 300 kilometers per hour to 350 kilometers per hour.
After National Day, the joint debugging and joint test will be launched.
The Chengdu-Chongqing high-speed rail with a total length of 308 kilometers will operate at a speed of 350 kilometers per hour, which will form the Chengdu-Chongqing "one-hour living circle" and promote the historic leap from the Chengdu-Chongqing national urban agglomeration to a world-class urban agglomeration.
Wuhan, which is the "Nine Provinces", has built a high-speed rail network connecting Shanghai-Hanrong-Chengdu High-speed Railway, Beijing-Guangzhou High-speed Railway, Xiwu High-speed Railway, Wujiu High-speed Railway, Wuhang High-speed Railway, Wuxian Intercity, Wushi Intercity and so on.
It takes about 1 to 3 hours to reach the surrounding cities from Wuhan.
At the same time, there are also national and regional central cities including Beijing, Shanghai, Zhengzhou, etc., which have built a high-speed railway network with the "eight vertical and eight horizontal" main corridors as the framework, regional connection lines of different speed grades and supplementary intercity railways. Realize a 1-3 hour traffic circle between adjacent large and medium cities, and a 0.5-2 hour traffic circle within an urban agglomeration.
The rapid development of China's high-speed railway is changing the way Chinese people travel.
It is estimated that by the end of 2020, the national high-speed rail network will cover 94.7% of cities with a population of 1 million or more.
Set a new benchmark for the construction and operation of high-speed rail in the world
On July 1, 2020, my country’s independent design and construction of the world’s first Shanghai-Sutong Yangtze River Highway and Railway Bridge with a kilometer-level main span was completed. It was opened and operated simultaneously with the Shanghai-Sutong Railway, marking my country’s success in conquering a kilometer-level ultra-large span Bridge technology.
"The design and construction technology of the Shanghai-Sutong Bridge has achieved 5'world firsts', which is a milestone in the history of railway bridge construction in my country and the world." Deputy Chief Engineer and Construction Department of China National Railway Group Co., Ltd. (hereinafter referred to as China Railway Group) Said Wang Feng, director and director of the Engineering Supervision Bureau.
Previously, on September 21, 2017, the Fuxing EMU took the lead in commercial operations on the Beijing-Shanghai high-speed rail at a speed of 350 kilometers per hour, setting the world's highest commercial operation speed for high-speed rail and setting a new benchmark for the world's high-speed rail construction and operation.
Subsequently, a number of new-type EMUs of Fuxing, including 17 long formations of 350 kilometers per hour, 8 formations of 250 kilometers, and power concentration of 160 kilometers, were successfully developed and put into operation.
Since 2016, China Railway has established a railway technology innovation system with enterprises as the main body, extensive participation of scientific research institutes and universities, close integration of production, education, research and use, and collaborative innovation. And industrialized application, formed a batch of major scientific and technological innovations such as Fuxing, high-speed railway technology reached the world’s leading level, and developed a complete set of high-speed railway operation and management technologies suitable for long-distance operation under complex road network conditions, and built a set of Speed grade, mature and complete high-speed rail technology system.
Intelligent railway technology innovation realizes leading
On September 16, 2020, the Beijing-Xiong Intercity Railway connecting Beijing and Xiong'an New District began a joint test.
The Beijing-Xiong Intercity has a total length of 106 kilometers and a design speed of 350 kilometers per hour. It is known as the benchmark and model of China's high-speed rail construction in the new era.
"This high-speed railway is also the first full-line, full-professional, and full-process digital twin railway that uses BIM (Building Information Modeling) technology to achieve virtual construction in the national railway construction." said Yang Bin, commander of the Jingxiong Intercity Railway Command.
Previously, on December 30, 2019, the world's first intelligent high-speed rail, the Beijing-Zhangjiakou high-speed rail, achieved 350 kilometers per hour automatic driving in the world for the first time.
During the "13th Five-Year Plan" period, China Railway Group relied on key projects such as Smart Jingzhang and Smart Jingxiong to vigorously promote the innovation of smart construction, smart equipment, and smart operation technology, and initially established a smart railway technology system, data system and standard system.
Established a complete BIM technical standard system, successfully constructed a BIM-based collaborative design system for railway engineering, developed a multi-disciplinary BIM integrated design platform, realized multi-source data integration for survey and design, studied and mastered assembly-style architectural design and modular manufacturing technology, digital Twin railway technology.
