At April 1, 2017
The state council officially issued the document
Decided to set up a state-level new district
The Xiong-An new area was successfully launched
As a second-class large city, the Xiong-An new area is highly positioned
It aims to create a Beijing-Tianjin-Hebei city cluster that will surpass New York
The planning and construction of the new district will take a specific area as the starting point for the development
The starting area is 100 square kilometers
The medium-term development plan covers an area of 200 square kilometers
The long-term planning area is 2000 square kilometers
In other words, the future area of the Xiong-An new area will reach 2,000 square kilometers
Such a large city is not without a convenient transportation hub
The Xiong-An high-speed railway station was successfully launched
As the largest high-speed railway station in Asia
The total area of the Xiong-An station is about 150,000 square meters
The total floor area is 470,000 square meters, which is equivalent to 66 football fields
The station is located in the northeast of Xiong-An city
It is 20 kilometers away from the Xiong-An starting area
The station house adopts the shape of a water droplet ellipse
There was also a valley of light in the middle of the roof, which allowed the light to ente
A crack in the valley of light
While solving the problem of lighting and ventilation in the waiting hall under the bridge
Formed a very characteristic optical valley
Optical valley will be Beijing, Beijing, Hong Kong, and Taiwan farm and Tianjin farm natural division
It also becomes an outdoor landscaped courtyard
As up and down through the daylighting corridor
Bring in natural light and landscape
The design is similar to Beijing’s Daxing airport
When we stand in Beijing Daxing airport and Xiong-An station
A lot of natural light will come in through the roof
Don’t turn on the light even on cloudy days
Natural light is abundant throughout the station room
Xiongan station house USES three floors above ground
Underground two-story construction, the total size of the station 11 19 line
Beijing, Hong Kong and Taiwan for 7 12 lines, Jin Xiong for 4 7 line
In fact, from the building area alone
Xiongan station is not the largest in Asia
The Shanghai Hongqiao station, for example, has a total area of 1.3 million square meters
The total investment is 15 billion yuan
Nanjing station area is as high as 2 million square meters
So why is Xiong-An called the largest station in Asia?
This is due to its clever design
The size of a high-speed rail station cannot be measured by area
I’m going to look at its stock channel
Xiongan station has planned 11 lines in the early stage, which means there are 19 high-speed railway lines
Later, it will increase to 13 sets of line 23
When you look at it
How would it feel to have 23 high-speed rail lines tied first?
Besides, Xiong-An station adopts the mode of integration of station and bridge
Ballastless track used directly within the range of station house
This is very rare in the world
However, the operation condition of the high-speed railway station with the combination of station and bridge is complicated
It is difficult to analyze dynamic performance and structural stability
Structure precision and deformation control are required
This poses a huge problem for builders
The main body of the Xiong-An station is divided into five levels
The station is mainly on the ground floor and auxiliary on the elevated floor
Ground layer outbound
According to the construction personnel, The ground floor of the station house is the ground waiting for hall and the supporting public station
The second floor is the platform floor and rail transit R1
R2 line reserved platform floor, the third floor for the elevated waiting hall
The ground floor is for commercial development
The underground second-floor reserves space for the planning of M1 line
Take into account all future lines and plans to be laid
Thus, secondary construction is avoided
As the largest high-speed railway station in Asia
The Xiong-An station is of course extremely difficult to build
The foundation pit of Xiong-An high-speed railway station has a large area and high depth
The crack control of super long and thick mass concrete has a high requirement
Besides, most of the space of the project is tall space
And the section size of the concrete member is large
The maximum section of the frame beam is 1.7 meters by 3.9 meters
The maximum span is 30 meters
The design and safety control of high death support system is a major difficulty in engineering
The entire station is the same as Beijing Daxing airport
Use the steel structure to erect
The maximum thickness of the steel plate is 8 cm
The heaviest steel sections reach 36 tons
Whether in transportation, installation or welding
Are the control focus of the whole project
At present, the underground main structure of Xiong-An station has been completed
The station building is under construction
It is expected to be in use by the end of 2020
When the station is completed
Xiongan new area can go directly to Beijing and Tianjin
Shijiazhuang and other major cities in Beijing, Tianjin, and Hebei
Connecting different regions of central China, south China, northwest China, southwest China, and northeast China,
Realize a half-hour traffic circle between Xiong-An new area and Beijing and Tianjin
With Shijiazhuang 1 hour traffic circle
The structure of the Beijing-Tianjin-Hebei high-speed railway network will be further improved
We will facilitate people’s travel along the routes
To improve the radiation capacity of the new area to the whole country
We will promote the coordinated development of the Beijing-Tianjin-Hebei region
All have very important significance
In the future, four high-speed railway stations will be built in the Xiong-An new area
Integration of the Beijing-Tianjin-Hebei city cluster transport framework
To provide people with a faster and more convenient way of transportation
