[Bajo la dirección del pensamiento de Xi Jinping sobre el socialismo con características chinas para una nueva era: una nueva era, un nuevo capítulo]
Guangming Daily reporter Zi Qian
At 10:18 am on December 27, the C2702 Fuxing train departed from Xiong’an Station, the largest newly built station of the Beijing-Xiong Interurban Railway. At 10:38 AM, the C2701 Fuxing train departed from Beijing West Station, twice. The launch of the train marked the opening and operation of the Beijing-Xiong Intercity Railway. After the opening of the Beijing-Xiong Interurban Railway, the shortest travel time from Beijing West Station to Xiong’an Station is only 50 minutes, and the shortest travel time from Daxing Airport to Xiong Station. ‘an is 19 minutes.
On December 27, the new Beijing-Xiong’an Intercity Railway section of Daxing-Xiongan Airport was opened for operation, the Beijing-Xiong Intercity Railway was fully connected, and Xiong’an Station was put into operation simultaneously.

Digital design accounts for the “digital twin” high-speed rail
The Beijing-Xiong Interurban Railway is drawn from the Beijing West Railway Station, with a total length of 91 kilometers and a maximum design speed of 350 kilometers per hour. Five stations will be built in Beijing Daxing, Daxing Airport, Gu’an East, Bazhou North and Xiong’an.
“Among the railway lines in which I participated in the design, the Beijing-Xiong Interurban Railway has the most innovative points. Through digital design, its opening has harvested a physical high-speed railway and virtual digital high-speed railway to the the same time, achieving the ‘digital twin’ of high-speed railway. Kang Xuedong, deputy chief engineer of China Railway Design Group Co., Ltd., said that the “digital twins” refer to bridges, subgrade, tunnels and four floors of energy (communications engineering, signal engineering, power engineering and electrification engineering) in the railway construction process. Different types of projects are first transformed into data, converted into three-dimensional perspective images, and then virtualized into reality, making it more convenient to manage and maintain all aspects of the railroad throughout the life of the project.
In addition, Beijing-Xiong Interurban Railway is China’s first high-speed intelligent railway designed with building information model technology throughout the process and professionally. It also applies cutting-edge technologies like the Internet of Things and cloud computing, and has more than 70 smart designs.
“Beijing-Xiong Interurban Railway has done a lot of exploration and practice in intelligent engineering construction, which not only improves construction quality and efficiency, but also saves labor cost.” Kang Xuedong introduced that the smart beam yard relies on building information model technology to create automated CNC steel bars. The work efficiency of the production line increases by 25%.
“Relying on these technologies, the Beijing-Xiong Interurban Railway has achieved a number of achievements such as intelligent beam yard, intelligent prefabricated building design, automatic steel processing, intelligent plate mill, intelligent subgrade compaction, intelligent line pre-configuration. contact and intelligent construction “. Kang Xuedong said that these technologies have also made significant advances in the automation of steel bar processing plants, precast plants, smart construction and smart construction sites.

Smart equipment enhances passenger travel experience
“The appearance of the Xiong’an station building adopts the design theme of ‘Qinglian Dilu’. The roof gradually changes from solar panels to solar panels from the center to the periphery. It is not only rich in layers, but also able to effectively use solar energy, which is expected to save electricity by 30%. The relevant official said that a 15-meter wide “light corridor” was also designed between the parking lots, which not only effectively improved the environment of lighting and ventilation of the waiting room on the ground, but also saved electricity for the station lighting.
In terms of interior design, to implement the integrated construction concept, Xiong’an Station ground waiting room innovatively adopted large-scale “building information model + fair-faced concrete” technology to build the country’s first passenger station with 527 curved beams and 192 flourishing columns. The concrete waiting room has straight corners, smooth arches and a tall, beautiful structure, wins with a fresh and natural wind and is more in line with the requirements of green buildings.
In the field of intelligence, the Xiongan station also uses a number of innovative technologies. According to Liu Weiqun, Secretary of the Party Committee and Chairman of China Railway Design Group Co., Ltd., the health monitoring system built by Xiong’an Station based on building information model technology can monitor structural parts. station building performance changes in real time and predict the performance changes of the station building structure. At the same time, with the use of intelligent building technology, Xiong’an Station has also achieved centralized control and energy efficiency management of building equipment systems such as elevators, air conditioners and lighting, reducing consumption. overall energy of the building and improving the waiting and driving environment for passengers.
Integration of concepts to create a green ecological corridor
Beijing-Xiong Interurban Railway has adhered to the concept of green ecology from design to construction and achieved the transformation of high-speed railway lines from gray infrastructure to green ecological infrastructure.
“In the landscape design concept, the department of railways will integrate multiple elements to create an ecological corridor composed of diversified landscapes, fields, gardens, plants and cultural landscapes, so that there are four stations along the railway.” He said that in order to integrate the railway construction with the urban landscape, the Xiong’an traction substation adopts the completely underground sunken plaza design, creating the first fully underground traction substation of the national railway.
In addition, in the design of the station, the Beijing-Xiong Interurban Railway also actively incorporates cultural elements from various places along the line, inherits history and culture, and demonstrates humanistic values. Kang Xuedong said that the design of Gu’an East Station is mainly based on the large water wave roof and tree-shaped corridors, which fully reflect the ecological culture of the “Chinese hot spring city” and the ” city of mineral water “of Gu’an; Bazhou North Station design Mainly adopts the combination of “dragon shape” and “gate”, which fully embodies the historical culture of Bazhou “the key of the three doors and the key of Jizhong”; Xiong’an station design concept is inspired by Xiong’an water culture, Appearance is drop-shaped oval shape, adopting the theme of “green lotus drip”, complementing the blue modern city and green.
“In the design of bridges along the line, the cultural landscape and connotation are also contained.” Kang Xuedong said that the pattern of the bridge railings and sidewalk decks throughout the line adopts lotus patterns, and the design concept is taken from the meaning of lotus in Baiyangdian, Xiong’an New District. Continuous girder arch covering through Daguang-Guangzhou highway. The inner arch ring adopts cool colors and the outer arch ring adopts warm colors. When looking at the railway bridge from the road, the colors are beautiful and rich, showing a rainbow effect, implying a colorful and beautiful life. .
