Author:Holy Ganzi Time:2022.08.02

From July 29th to 31st, the Yakang Expressway successfully passed the acceptance of the Ministry of Transport and ended a successfully in the entire project construction painting, marking the first new journey of operation from the highway from the Sichuan Basin to the Qinghai -Tibet Plateau.

The acceptance committee composed of 23 experts inside and outside the province listened to the reports of construction, design, construction, supervision, management, quality supervision and other units, checked the relevant documents and materials of engineering construction, and conducted on -site inspections on the entire line of projects. Unanimously agreed After completion acceptance, the comprehensive evaluation level of engineering construction projects is excellent.

What is the road of Yakang Highway, known as the "Climbing Highway Construction Mount Everest"

The Ya'an to Kangding Expressway is a section of the National Highway Network Ya'an to Xinjiang Yecheng Link (G4218). The project is about 134 kilometers in length, with an estimated investment of 23 billion yuan and a construction period of 5 years. The project was invested and constructed by Shu Dao Group. In September 2014, the project was launched across the board. At the end of December 2018, the Yakang Expressway was completed nine months in advance for a trial opening operation.

The project starts from Caoba Town, Yucheng District, Ya'an, east of Kangding City, 109 bridges (including 7 bridges), 28 tunnels (including 10 special tunnels), and 11 interchange.

Yakang High -speed Control Project -Luding Dadu River Bridge

One of the control projects of Yakang Expressway, Luding Dadu Bridge, is located in Luding County, Ganzi Prefecture. It is a fifteenth minute drive from Luding County. , The total length is 1411 meters, the main bridge is 1100 meters long, the same bridge type ranks first in the province, and the tunnel anchor is 159 meters, ranking first in the world. Adopting steel hybrid bridge roads, the cost exceeds 1 billion yuan, facing extremely high earthquake intensity (eight degrees), complex wind farm conditions, extremely unstable high -steep side slopes, etc., because of the difficulty of construction technology, it is hailed as the difficulty of construction technology. "Sichuan -Tibet First Bridge" started on September 1, 2014, completed the main Liang Heilong on February 6, 2018, and opened to traffic on December 31, 2018.

Erlangshan Tunnel

The total length of the Erlangshan Tunnel is 13,459 meters. It is located in the Earthquake intensity zone of the Du Du Du Du Du Dian. It crosses 13 regional fracture bands. The project officially penetrated on September 26, 2017. The trial operation was opened on December 31, 2017. The first Tianshi Erlang Mountain, which crosses the Sichuan -Tibet Highway, is connected to Tianquan County, Ya'an City and Luding County, Ganzi Prefecture. One tunnel. The completion of the tunnel will turn over the time of Erlang Mountain, shortening from more than an hour in the past to 15 minutes.

The completion of the Yakang Expressway has ended the history of Kangding City, where the Ganzi Tibetan Autonomous State Government is located, and shortened the driving time from Chengdu to Kangding from more than 7 hours to more than 4 hours. The dream of the Ganzi people's highway and the highway from the highway from the plain to the plateau and the super engineering construction capacity.

The results of Yakang high -speed project

The Yakang Expressway project has obtained 70 patents, 5 softening, 5 monographs, 21 items, 22 QC results, 21 provincial and ministerial science and technology progress awards, and 2 standardized safety construction sites. He has won a number of honors such as the Gold Award of the International IBC "Gustav Linden", the Luban Award of China Construction Engineering, the National High -quality Engineering Award, the Quality Engineering Award, and the Tianfu Cup Gold Award. The Management Department and the China Federation of Trade Unions were selected as "Ping An Engineering" of highway water transportation construction in 2018-2020. Successfully selected "National Engineering Archives" (traffic volume) and "70th anniversary of the founding of New China · Affects the Top Ten Projects of Sichuan".
