By the end of 9, the country's railway operating mileage will reach 4,5 kilometers, and the high-speed rail mileage will reach <>,<> kilometers.
About 80% of the "eight vertical and eight horizontal" main channels have been completed and put into operation
In 2016, the "Medium and Long-term Railway Network Plan" proposed to build a "eight vertical and eight horizontal" high-speed railway main corridor, with a total design scale of about 4,5 kilometers. By the end of 2023, 3,64 kilometers of the "eight vertical and eight horizontal" main corridors have been completed and put into operation, accounting for about 80%, and 0,67 kilometers are under construction, accounting for about 15%.
The "eight vertical" passages refer to the coastal passage, the Beijing-Shanghai passage, the Beijing-Hong Kong (Taiwan) passage, the Beijing-Harbin - Beijing-Hong Kong-Macao passage, the Hunan passage, the Beijing-Kunming passage, the Baoyin (silver) sea passage, and the Lanzhou-Guangzhou channel.
The "eight horizontal" channels refer to the Suiman Channel, the Jinglan Channel, the Qingyin Channel, the Land Bridge Channel, the Yanjiang Channel, the Shanghai-Kunming Channel, the Xiamen-Chongqing Channel, and the Guangzhou-Kunming Channel.
"Among them, the Beijing-Shanghai channel, the Beijing-Harbin - Beijing-Hong Kong-Macao channel 'two verticals', the Qingyin channel, the land bridge channel, the Shanghai-Kunming channel, and the Guangzhou-Kunming channel 'four horizontal' have been connected. Deng Lihong, deputy director of the Planning Department of the Development and Reform Department of China Railway Group, said that in 2023, positive progress will be made in the construction of the Beijing-Hong Kong (Taiwan) channel and coastal channel.
Taking the coastal passage as an example, it runs from Dalian (Dandong) in Liaoning Province in the north to Beihai (Fangchenggang) in Guangxi Province in the south, connecting the eastern coastal areas and connecting the Beijing-Tianjin-Hebei region, Shandong Peninsula, Yangtze River Delta, Pearl River Delta, Beibu Gulf and other urban agglomerations.
"The Fuzhou-Xiamen high-speed railway, Guangzhou-Shantou high-speed railway, and Shanshan high-speed railway, which will be opened in 2023, are all part of the coastal corridor, and a major breakthrough has been achieved in the construction of the coastal corridor. Deng Lihong introduced that at present, the coastal passage from Zhangzhou in Fujian Province to Shantou in Guangdong Province has been approved by the National Development and Reform Commission, and only the Shanghai-Zha-Hangzhou and Wenfu high-speed railways are still in preliminary work. In 2024, China Railway Group will speed up the construction of the sections from Shenzhen to Jiangmen in Guangdong and Hepu to Zhanjiang in Guangdong, and strive to start construction of the Zhangzhou to Shantou section as soon as possible.
As the main channel of the national railway network, the "eight vertical and eight horizontal" trunk railway has an obvious economic driving role.
Let's look at the Beijing-Shanghai channel first. In the first 10 years of the opening of the Beijing-Shanghai high-speed railway, a total of 13.5 billion passengers were transported, and the cumulative journey exceeded 15.8 billion kilometers, equivalent to nearly 4,2023 laps around the equator. In the first half of 2499, the Beijing-Shanghai high-speed railway trains carried 299.7 million passengers, a year-on-year increase of <>.<>%.
As the fastest high-speed railway in the world, the Beijing-Shanghai high-speed railway has a minimum departure interval of only 4 minutes, driving the rapid and orderly flow of talents, technology, capital and information along the line. Relying on this high-speed railway, 24 new high-speed rail cities and new high-speed rail areas have risen along the line, which has become an important carrier for attracting industrial agglomeration and promoting industrial optimization layout.
Let's look at the Beijing-Harbin - Beijing-Hong Kong-Macao channel. For example, the journey time from Beijing to Guangzhou, Guangdong Province, has been reduced from more than 40 hours to about 7.5 hours, realizing the connection between Beijing-Tianjin-Hebei, the middle reaches of the Yangtze River, and the Pearl River Delta urban agglomeration. Data shows that in the first 10 years of opening, the Beijing-Guangzhou high-speed railway has sent a total of 16.9 billion passengers, and the development momentum of the regions along the line is stronger, and the people's lives are getting better and better.
In 2023, the passenger flow of the Fuzhou-Xiamen high-speed railway and the Guangzhou-Shantou high-speed railway in the newly opened coastal passage is also quite hot. The average daily passenger flow of the Fuzhou-Xiamen high-speed railway is 2,4 passengers, with a peak of 3,8 passengers, and since the opening of the Guangzhou-Shantou high-speed railway, a total of 7378,226 trains have been operated, transporting 7.<> million passengers.
Breakthroughs have been made in the fields of construction technology and equipment manufacturing
10,000-ton, ultra-long cantilever and special-shaped rotating bridges are increasingly appearing in construction.
"After years of exploration and accumulation, China's bridge turnaround construction technology has been quite mature, and there is large-tonnage turnaround bridge construction almost every month. Liu Yashuai, senior engineer of China Railway 2023th Bureau, introduced. In mid-November 11, the first three-dimensional asymmetric hanging basket construction rotating bridge in China was successfully rotated in Hefei, Anhui Province.
The rotating bridge is only a microcosm of the scientific and technological strength of China's railway engineering. Insisting on innovation is the first driving force to lead development, the railway innovation ability continues to improve, and the strength level has reached a new level.
-- Major projects demonstrate extraordinary strength.
A bridge, creating 3 world's bests. With the opening of the Chengdu-Ziyi high-speed railway, the Yibin Lingang road-rail dual-purpose Yangtze River Bridge was officially put into use. This cable-stayed steel box girder bridge, the world's widest and largest span, presents a spectacular scene of high-speed rail, automobiles and pedestrians passing on the same floor.
One station house, 4 world records. How to build a 38,4300-ton steel structure the size of <> standard basketball courts? Chinese engineers came up with the process of jacking, first welding the structural parts in an open space nearby, and then pushing them into place as a whole.
At the end of 2023, the steel structure of the elevated layer of the east station building of Jiangxi Lushan Station successfully spanned 10 railway trunk lines, setting a new 4 world records in one fell swoop for the width, weight, area and number of slide rails of the steel structure across the line.
Crossing rivers, lakes and seas, passing through canyons, connecting mountains...... In 2023, China's railways will open roads and build bridges in the face of mountains, and a number of super projects will be successfully completed, winning the world's attention.
-- A major breakthrough has been made in equipment manufacturing.
If you want to do a good job, you must first sharpen your tools. In the past year, China's railway equipment has continued to innovate and help engineering construction to be more intelligent and efficient.
On December 2023, 12, the "Keihin Tongxin" shield machine was successfully launched, responsible for the construction of the new Keihin Railway Tianjin Airport Tunnel No. 8.
"For the first time, this shield machine applies artificial intelligence depth learning Xi technology to a slurry large shield project, and the shield machine can automatically receive and process massive data to achieve unmanned autonomous cruising and tunneling. Li An, the technical director of the project of the second branch of the Keihin Railway of the Fourth Bureau of China Railway, said.
On December 2023, 12, Guangzhou Baiyun Station was successfully put into use. This is China's first large-scale use of robot construction of railway engineering projects, with 26 kinds of intelligent robots involved in the construction.
The main bearing of the world's largest diameter shield machine was successfully rolled off the assembly line, and the domestic high-end underground tunneling equipment has since had a full range of "Chinese heart" with independent intellectual property rights...... In 4, the convergence and integration of technological innovation and broad transportation application scenarios will promote the significant improvement of China's railway equipment manufacturing level.
-- Transportation equipment ushered in a new upgrade.
On June 2023, 6, the test train equipped with CR28 new technical components ran a new record of 450 kilometers per hour and 453 kilometers per hour at the Meizhou Bay Bridge of Fuzhou-Xiamen High-speed Railway, marking the phased results of the development of CR891 EMUs.
As a new generation of EMUs, CR450 EMUs strive to achieve higher speed, safer, more environmentally friendly, more energy-saving and more intelligent, and continue to consolidate and expand China's leading advantages in the world of high-speed rail. This year, the CR450 EMU is expected to complete prototype manufacturing and carry out type tests.
