China News Service, Xiong’an, December 26 (Niu Lin, Cui Tao, Li Xiaowei) From Beijing West Railway Station to Xiong’an Station, one of China’s fastest-designed railways, the Beijing-Xiong Intercity Railway, has entered the countdown. In the 92.78 kilometers long distance, there have been many "firsts" and "intelligence" in the history of Chinese railways.

First time: "sound-proof tunnel" and underground traction substation

　　"Among the railway lines I participated in the design, the Beijing-Xiong Intercity Railway has the most innovative points." said Kang Xuedong, deputy chief engineer of China Railway Design Group Co., Ltd.

　　According to Kang Xuedong, near Beiluodian Village, where the Beijing-Xiong Intercity Railway passes by, there is a 847.25-meter-long high-speed railway with a speed of 350 kilometers per hour. This is the first case at home and abroad.

This "sound-proof tunnel" uses a circular steel frame and a metal sound-proof board unit on the periphery, which can minimize noise and effectively solve the impact of high-speed train operation on concentrated residential areas along the line.

　　There are many such "firsts".

On the south side of Xiong'an Station of Jingxiong Intercity Railway, there is a traction substation hidden underground, which is mainly responsible for supplying power to the catenary of Jingxiong Intercity Railway.

According to the overall planning and design of the Xiongan New District, the railway construction and the urban landscape should be integrated.

The Xiong'an traction substation adopts a basement layout and is China's first sunken high-speed rail traction substation.

　　In addition, the Beijing-Xiong Intercity Railway first applied the integrated design and construction of the bridge assembly, and realized the design and construction of the fully assembled structure from the foundation, piers, beams to the bridge deck system for the first time in the railway field. Significant changes have filled the gap in the field of bridge assembly in China.

Intelligence: Relying on BIM technology to design intelligently across the board

　　The Beijing-Xiong Intercity Railway is about to open for operation, and it is particularly eye-catching in terms of "intelligence".

　　Kang Xuedong said that the Beijing-Xiong Intercity Railway adopted the BIM (Building Information Modeling) application for the first time for the entire line, all professions, and the entire design stage. While effectively improving the means and level of railway survey and design, it also laid the foundation for the digitization and intelligence of the entire Jingxiong Intercity Railway. basis.

Relying on BIM technology, a series of achievements such as intelligent beam yard, intelligent assembly building design, automatic steel processing, intelligent plate factory, intelligent compaction of subgrade, intelligent pre-configuration of contact network, and intelligent construction have been realized in the Beijing-Xiong Intercity Railway Project.

Half an hour: From Xiong'an to Beijing

　　The Beijing-Xiong Intercity Railway leads from Beijing West Railway Station. The new line starts from Beijing Liying Station and ends at Xiong'an Station. The main line is 92.78 kilometers long.

Among them, the new section from Daxing Airport to Xiong'an has a total length of 58.81 kilometers and a design speed of 350 kilometers per hour. It is expected to open and operate at the end of 2020.

By then, Beijing will reach the Xiongan New Area within half an hour.

　　"After optimization and innovation, we took advantage of the adjustment of the railway's own traffic flow, and adjusted the ordinary passenger cars of the Beijing-Kowloon Railway to Fengtai Station, thus making the Beijing-Kowloon Railway a part of the Beijing-Xiong Intercity Railway, which saved a lot of construction costs." Said that passengers in Xiong'an New District can go directly to Beijing West Railway Station and transfer to Beijing Rail Transit in time, reducing the number of transfers.

　　Kang Xuedong said that the Beijing-Xiong Intercity Railway is a railway line tailored for the Xiongan New Area, and is the first major transportation infrastructure to be constructed in the Xiongan New Area.

The opening of the Beijing-Xiong Intercity Railway is of great significance for supporting the construction of the Xiongan New Area and promoting the coordinated development of Beijing-Tianjin-Hebei.
