Original title: The west extension of the Daxing Airport North Line Expressway will run through Zhuozhou, Hebei, into Beijing, and reach the East Sixth Ring Road all the way
Before the cold winter season, the Daxing Airport North Line Expressway west extension project ushered in an important node on October 19-the pavement asphalt layer entered the final stage, laying the foundation for the full line through the end of the year. Currently, the two control projects of the west extension section of the Yongding River Bridge and the Beijing-Kaisha Expressway Interchange have all been completed. Through this “five vertical and two horizontal” transportation network, the only horizontal road channel, Zhuozhou, Hebei, can enter Beijing all the way to the East Sixth Ring Road, and there is no need to detour the Beijing-Kaiwang Expressway to Daxing Airport, and the traffic speed is greatly improved.
The most advanced paver and environmentally friendly asphalt vehicles are on the battlefield
Two kilometers west of the Jingkai Expressway, the west extension of the Daxing Airport North Line Expressway crosses the road section of Yufa Town. Several pavers and rollers are busy working to finish the paving of the last section of the asphalt layer.
At the construction site, two green pavers equipped with infrared detectors attracted attention. “This is the most advanced paver at present. It is equipped with 3 infrared probes in the front, middle and rear. After the computer inputs the asphalt thickness, it is automatically leveled through ground detection. The error is less than 0.5 mm. Each paver can The shop is 13 meters wide and highly efficient.” said Yang Guang, the person in charge of the pavement project in the west extension section of the North Line of the Daxing Airport North Line of the China Railway 16th Bureau. The vehicle transports the asphalt mixture in an airtight way.
Severe cold weather is unfavorable for road construction. In order to “speed up” with the weather, a large amount of mechanical equipment and personnel has been invested in the project of the west extension section. “Workers give up holidays and rest, and have three meals a day on the construction site. The project department provides workers with milk, fruit and other extra meals every day. Together, we work together and work hard for the whole line.” Yang Guang introduced, since the beginning of September A total of 140,000 tons of asphalt was paved, and at most more than 20 machinery and equipment operated at the same time. Next, it will enter the phases of electromechanical, traffic security, and greening construction.
Preliminary completion of the cross-Beijing high-speed interchange
Not far from the road paving site, the main line of the cross-Jingkai Expressway has been completed. Three of the four new ramps have been completed, one from west to east and two from east to west, extending the north line of the Daxing Airport Expressway to the west. Connected with the main line of Jingkai Expressway. The length of the main line bridge across the Beijing-Kaisha Expressway Interchange is 1.286 kilometers, the longest of the three ramps is 1.3 kilometers, and the shortest is 300 meters.
The west extension of Daxing Airport North Line Expressway is located in Yufa Town, Lixian Town, Panggezhuang Town and Anding Town in Daxing District. It starts from the east side of Jingkai Expressway and ends at the middle section of Yongding River. The route crosses Yongxing from east to west. He, the south extension of Luqiu Road, Luxi Road, Xikong Road, Shixi Road, Yongding River Irrigation Canal, Yongding River Zuodi Road, the main road is 8.16 kilometers long, adopts two-way 8 lanes, and has a design speed of 120 kilometers per hour.
“A total of 9 bridges have been constructed in the west extension section. The cross-Beijing-Kaisha Expressway interchange and the Yongding River Bridge are two important controllable difficulties.” Yang Guang said. The Yongding River Bridge is about 908 meters long. Pavement was completed at the beginning of the month.
It can be seen on the map software that the Beijing section of the Jingxiong Expressway currently under construction will also be interconnected with the Hebei section of the Daxing Airport North Line Expressway in the future. The vertical and horizontal intersection is located on the west side of the Yongding River Bridge.
Open up “one horizontal” in the “five vertical and two horizontal” transportation network
Daxing Airport North Line Expressway is divided into west extension section, middle section and east extension section. Among them, the middle section (the first phase of the project) and the east extension section have been opened before. The Langfang section is connected.
After the airport north line expressway is fully opened to traffic, it will enter the Yongding River Bridge in the Beijing-Hebei boundary from Zhuozhou, Hebei, and it can be along the Daxing Airport North Line Expressway eastward to reach the Jingkai Expressway, Daxing Airport Expressway, and Beijing-Taiwan Expressway. Preliminary calculations show that it can be about 35 minutes faster than the Beijing-Kaisha Expressway or the Capital Ring Expressway in the past. It only takes about 32 minutes to drive from the Beijing-Hebei area to Daxing Airport, which is nearly 20 minutes less than in the past. Dong Xiaohui, Secretary of the Party Branch of the Pavement Project of the North Line West Extension Project of the China Railway 16th Bureau Daxing Airport, introduced that after the opening to traffic, Zhuozhou, Hebei and Beijing were closely connected, shortening the time and space distance between Hebei and the capital on the west side of Beijing, and giving play to the capital. The radiation effect of the economy.
Around Daxing International Airport, the city is forming a “five vertical and two horizontal” transportation network. Among them, the “five verticals” include the rail transit Daxing International Airport Line, the Beijing-Xiong Intercity Railway, the Jingkai Expressway, the Beijing-Taiwan Expressway, and the Daxing International Airport Expressway; the “two horizontals” include the Daxing International Airport North Line Expressway and the city International railway tie line.
As the only horizontal road passage in the “five vertical and two horizontal” transportation network, the Daxing Airport North Line Expressway is fully connected, which has improved the Beijing-Tianjin-Hebei regional expressway network and the Beijing trunk road network, supporting the development of industrial parks around Daxing International Airport and driving Economic development in the southern region.
