Look first! The Xiongan Station was put into use at the end of the month, which was the first major infrastructure project in the Xiongan New District

The land of Yanzhao in the middle of winter is vast.
From Yufa Town, Daxing District, at the junction of Beijing and Hebei, 60 kilometers south along the Daguang Expressway, you arrive at the Xiong'an Station of the Jingxiong Intercity Railway, which has entered the sprint stage of construction.
Under the tall glass curtain wall, workers are laying ground stones for the entrance.
Wang Xingyun, secretary of the Party branch of the Xiong'an Station Project Department of China Railway Construction Engineering Group, told the Beijing Daily client reporter that soon, looking out from the entrance of the station, the area where you can see will be covered by greenery.
The builders of Xiong'an Station were hailed by General Secretary Xi Jinping as the “vanguard” of the “Millennium Plan”.
At the end of this year, with the opening of the Beijing-Xiong Intercity Railway, Xiong'an Station, the first major infrastructure project in the new district, will be completed and put into use.
The epidemic was delayed for two months, and I did my best to grab the schedule
Xiong'an Station is the Beijing-Xiong Intercity Terminal, where the Beijing-Hong Kong-Taiwan high-speed rail, Beijing-Xiong Intercity, and Tianjin-Xiong Intercity will meet here.
The exterior design of Xiong’an Station is inspired by the water culture of Xiong’an New District. It looks like a dewdrop on a lotus leaf when viewed from above.
The station building is 606 meters long, 355.5 meters wide, and 47.2 meters high. The total construction area is 475,200 square meters, which is the size of six Beijing stations.
At the beginning of 2020, the new crown epidemic broke out suddenly, and Hubei became the hardest-hit area.
Unfortunately, two-thirds of the construction workers of the China Railway Construction Engineering Xiong'an Station project are from Hubei.
Under strict control measures, the construction was suddenly in trouble.
The project department immediately used all channels and dispatched more than 100 buses to bring in more than 2,500 workers from Henan, Anhui, Hunan, Guizhou, Yunnan and other places, and finally resumed work in early April.
In order to grab back the two-month delay, the project department launched an emergency mobilization to prevent and control the epidemic and make every effort to grab progress.
Front-line workers work in two shifts, sometimes even in three shifts, working day and night; more than 70 project managers only sleep for four to five hours a day...the effort pays off, and the delayed construction period only took one month to get back. According to the original plan, the Xiong'an Station completed the task of capping the main structure with high quality on April 30.
Hundreds of experiments have been done for 192 "flowering columns"
The China Railway Construction Engineering Group, known as the "Trump of Railway Station Building Construction", has undertaken the construction of more than 60% of the domestic railway station buildings, and has built Beijing Railway Station and Beijing South Railway Station.
At Xiong'an Station, engineers who have experienced many battles compete to praise the "simple and low-key" concrete pillars in the future waiting hall.
"Generally, the structural construction of beams and columns will be covered with a layer of decoration materials. The clear water concrete column is cast in one time, and it is what it is poured into. Basically, no decoration is required." said Zhu Jiawu, an engineer from the China Railway Construction Engineering Project Department. , The large-scale application of the clear water coagulation column in Xiong'an Station pursues the comprehensive effects of green, warm, economic and artistic.
"You see, it has beautiful curves, all vertical and horizontal curves, and the look is natural and fresh. We call it'flowering column'. Call it'simple', but its technical content is not low at all."
In order to perfectly demonstrate the unique effects of clear water concrete columns, the technical team conducted in-depth research on steel bar structure, concrete mix ratio, formwork system, concrete construction technology, etc., did hundreds of tests, and spent more than 1 million yuan to build an entity For large and small models, I have tried using salad oil and hydraulic oil as mold release agents, and only then have the 192 clear water coagulation columns at Xiongan Station look like they are today.
Leading construction technology, all over the technology and wisdom elements
Wu Yadong, chief engineer of the Xiong'an Station Project Department of China Railway Construction Engineering Group, said that as a "pioneer" of the "Millennium Plan", the construction of Xiong'an Station not only integrates existing advanced technologies, but also undertakes the mission of innovation and leadership in the field of construction technology.
Elements of technology and wisdom can be seen everywhere on the hot construction site.
The construction volume of Xiong'an Station is huge and the number of construction machinery is very large. How to ensure that construction machinery "does not fight"?
According to reports, the on-site tower crane is equipped with an anti-collision system. The driver can eliminate blind spots through video in the cab, and has a clear view of the surrounding situation, greatly improving the safety factor.
The tower crane elevator also adds a face recognition system that has not been used in previous projects, which forms a "dual recognition" with fingerprint recognition, and only professionals with a driving license can enter.
Using the high-end construction intelligence platform on the site, engineers can monitor the construction site in an all-round way from mobile phones and computers at any time, and grasp detailed data of construction organization and construction progress in time to analyze the actual progress of the project and make necessary adjustments.
“When the floor slab was poured at one time, three construction flow sections were set up as planned. Later, it was discovered from the platform that only two sections were poured. We made adjustments based on this situation and added construction personnel and materials.” Zhu Jiawu said.
More than 700 days and nights passed in a flash. Wang Xingyun told reporters that for two years, all personnel in the project department have been self-motivating with the spirit of pioneering the path.
"As an engineering builder, being able to participate in such a significant project is a great fortune in my career. The Xiong'an Station has attracted worldwide attention. In the final sprint stage, we will continue to do our best to hand in satisfactory answers."
