Author:Changjiang Daily Time:2022.07.19

A few days ago, the International Railway Alliance issued and implemented the "High -speed Railway Design Infrastructure" standard and "High -speed Railway Design Power Supply" standard formulated by my country. Both standards are the first international railway standards in related fields.

The International Railway Alliance is the most influential professional international standard for the railway industry. The two standards released this time were hosted by experts organized by China National Railway Group. More than 20 experts from more than ten countries including France, Germany, Japan, Spain, and Italy participated, and it lasted for 4 years.

Based on the successful experience of the world's high -speed railway design and the advanced technologies of the system integration of the world, the two "standards" introduced the overall design concept of China's high -speed railway to absorb the loading of the Chinese high -speed railway trains, line spacing, roadbladder filler classification, and tunnel surrounding rock classification For basic key indicators, promote the Chinese CRTSIII -type plate -free rails and EMU motto, contact network system and other advantageous technologies. Finally, the overall design, lines, roads, bridges, tunnels, rails, stations, stations, stations, stations, stations, stations, stations, stations, stations, stations, stations EMU uses design concepts, key parameters and technical requirements in the fields of maintenance facilities, maintenance facilities, comprehensive protection, environmental protection, environmental protection, traction supply, contact networks, power supply and distribution and remote systems. It contributed China's wisdom and Chinese plan to the construction operation of the world high -speed railway.

Huo Shibao, chairman of the International Railway Alliance (UIC) High -speed Committee: International standards are an important technical basis for international trade and an important part of promoting the "Belt and Road" system rules. Relying on the international standardization platform, the amendment to the important technical standard system participating in the railway has significantly improved the international influence of China's railway standards.

11 system -level standards of China high -speed rail filling international gaps

As of the end of 2021, my country's high -speed rail operating mileage exceeded 40,000 kilometers, accounting for more than 2/3 of the global high -speed rail mileage. In recent years, the National Railway Group has focused on promoting international standardization. China's high -speed rail is moving from building a national business card to leading international standards.

In November last year, the International Railway Alliance has released the "High -speed Railway Design Communication Signal" standard for the formation of my country. The "infrastructure" and "power supply" standards released this time are the second and third international standards of the "High -speed Railway Design" series. In recent years, experts from the National Railway Group have presided over the revision of more than 60 important technical standards such as the International Railway Alliance high -speed railway, train network, and braking system. 11 high -speed railway system -level standards such as a series have filled the international standard gap in key areas such as high -speed railway implementation and design. Comprehensive and systematically include successful experience, main innovation results and advantageous technologies, including design concepts, technical equipment, key parameters to maintenance and maintenance, and compatible with the relevant technologies and needs of high -speed railways in other countries.

Huo Shibao, chairman of the International Railway Alliance (UIC) High -speed Committee: Integrated in my country's advantageous technologies and key parameters in international standards, provides standards for promoting China's railway technology, realizing the "going global" of China's railway system, full element, and entire industrial chain. Support, created favorable conditions.

China Enterprise Construction Madong Railway Project entered the peak construction period of construction

Right now, the East Coast Railway, which is undertaken by Chinese enterprises and adopted Chinese standards, has entered the peak construction period. As of the end of June, the two hard rock excavators have been launched in the key control project of the entire line, the construction of the Genting Tunnel.

The Malaysian Railway is the flagship project of China and Malaysia's "Belt and Road" initiative. The line is 665 kilometers in length, and the economic center of important towns and west coasts in the east coast of Malaysia. The project is expected to be completed and put into operation in 2026, and it will fill the gap that there is no railway through the Malaysian Peninsula.

Using the "China Standard" Yawan high -speed rail enters the rail paving stage

For the first time in my country's high -speed rail, the project where the full system, full element, and the entire industrial chain -Yawan high -speed railway has now entered the rail paving stage. As the first high -speed railway in Southeast Asia, what are the "Chinese standards" of 350 kilometers per hour?

The first station after departure from Jakarta is the Harry Station of the Yawan High Speed Railway. It can be seen that there have been no orbit for 30 kilometers near the station. This kind of no -orbit is a CRTS III plate -type non -orbit that uses independent research and development and independent intellectual property rights in my country.

Zhang Lixing, commander of the Yawan High -speed Railway Command of the China Railway Third Bureau of China: Zhang Lixing of the Type III orbit board has the advantages of simple structure and stable performance. In recent years, this has been used in the construction of Zhengxu, Beijing -Shen, and Ganshen high -speed rail. Plant rail board.

The CTCS-3-level control system of the three major core technologies used by the Yawan High Speed Railway is independently developed and produced by China Tong. It is the "brain and central nervous system" of the high-speed rail. Through the wireless communication network and ground wireless occlusion center. Realize the two-way information transmission of the car-land, adopt continuous speed control mode, and the system meets the two-line two-way operation.

Xiao Songxin, director of the Indonesian China High -speed Railway Corporation (KCIC) project: In the construction of the Yawan high -speed rail in Indonesia, a series of Chinese high -speed rail technical standards such as engineering design and construction equipment were successfully applied to provide technical support for the smooth progress of the project. The high -speed rail world is the leading position.

The Yawan high -speed railway is 142.3 kilometers in length, connecting the Indonesian capital Jakarta and the fourth largest city Bandung, with a maximum design speed of 350 kilometers per hour. After completion, Jaca's travel time between Bandung will be shortened from more than 3 hours to 40 minutes. The "China Standard" railway injects new driving force into the development of the line

In recent years, railways designed and built with Chinese standards have continued to extend in Asia, Africa, and Europe, bringing new impetus to the economic and social development of countries along the route.

In March of this year, the first project of the China Railway Technology Equipment and the EU Railway Interconnection Technical Specifications -the Hungarian -Seda Railway Serbia, Belgrade to the Novisad section, opened operations. The fast -iron train between the city's Novisard is directly connected. The maximum operating speed of the train has been increased from the original maximum 50 kilometers to 200 kilometers. The operating time is reduced from 90 minutes to 30 minutes. The transportation quality and efficiency have been greatly improved.

The China -Laos Railway, which connects Kunming and Laos in Yunnan, China, is designed in accordance with the standards of China Railway II, which mainly invests in the construction of China, jointly operates between the two countries, and directly connects with the China Railway Network. After seven months of opening and operation, Vientiane South Station completed the replacement, and the China -Laosaicai Railway achieved interconnection. The transportation time from Kunming, China to Thailand's Linchabian was shortened by about 1 day compared with the car replacement. The transportation cost was reduced by 20%. The above provides reliable capacity support for the construction of the Chinese and Old Economic Corridor and the China -ASEAN Destiny Community.
