The entire bridge tunnel ratio is as high as 61.37%

90 single tunnels (total length of about 107 kilometers)

328 single bridges (about 137 kilometers long)

Among them, the Green June River Bridge is a key control project of the Yuchu highway, located at the junction of Yimen County and Shuangbai County.

The bridge is 798 meters long, the bridge deck is a two -way 4 lane, the design speed is 100 kilometers per hour, and the two sides of the strait are directly connected to the tunnel. It is the largest suspension bridge of the world's single tower and single span. During the construction process, the construction party overcame the difficulties of the green juice rivers and the restricted construction environment, and independently developed a number of scientific research technologies and construction technology, which greatly shortened the construction period.

From Yuxi City Research and Town Duyushu Village, through 3 counties (districts) in 3 states, and ends near the Qingshan Reservoir on the north side of Chuxiong City. The total length of 190.597 kilometers of Yuxi to Chuxiong highway is organically integrated with the natural landscape along the line, like a green ribbon inlaid in the mountains and rivers in Central Yunnan.

Crossing the road to overcome difficulties

Yuchu high -speed engineering volume, high bridge tunnel ratio, and large investment amount are a veritable "super engineering". All road bases on the entire line are more than 47.76 million cubic meters. If it is built into a Great Wall with a height of 2 meters, it can be directly reached from Kunming.

Crossing the mountains such as Jinting Mountain and Zixi Mountain along the line, crossing the rivers and other rivers of Lianjiang, the Green June River, the bridge -tunnel ratio is as high as 61.37%. Among them, the total length of the tunnel is over 107 kilometers, and there are 4 tunnels over 3000 meters; the total length of the bridge is 137 kilometers.

The Yuchu high-speed TJ-16 standard created by the Sixth Bureau of China Railway belongs to the entire control project of the entire line. It is located in Pudian Town, Shuangbai County. %, High construction technology standards. Among them, the "two bridges, three tunnels and two interconnects" are key controlling projects, and wearing 214 provincial highways. The landform type is erosion -erosion of Zhongshan landforms. The construction difficulty and high risk of safety are called "encyclopedia" called tunnel disease.

Faced with the challenge, the builders strengthened technical research and set up a team of bridges, tunnels and integrated road base technical research teams. They successively overcome 3 major technical problems and 7 scientific research issues, focusing on solving the problem of on -site construction production, safety quality control problems, and creating "model models. Demonstration "project, build" quality jade ".

Deng Ping, commander of the Yugu high -speed engineering headquarters of China Railway, introduced that with the completion of the Yuchu high -speed speed, it further improved the central Yunnan road network and opened up the traffic artery of Central Yunnan. The Yuchu Expressway is connected to the G85 Kunming to Mo -Music National Expressway, G56 Hangzhou to Ruili National Expressway. At the same time, it is connected to the Mirita to Yuxi, both Wuding to Yimen, Chu Xiong -Da Yao highway to form internal internal The large traffic network pattern of external and interconnection and interconnection and interconnection, inject strong kinetic energy into the province's rational flow, enhanced urban radiation and driving force, unblocked scenic spots, and high -efficiency China -Laos and Lao Lao Railway.

Ecological priority to create green well -off road

The Yuchu high speed is more than 190 kilometers in length, with an average altitude of 1600 meters to 1700 meters. During the construction process, the participating units adhere to the construction principles of "green environmental protection" and "one tunnel, one scene". While building roads and rejuvenating bridges, the landscape greening is integrated into the folk customs and landscape characteristics along the line. It has characteristics, making Yuchu high -speed become an ecological road, travel road, and rich road.

Driving along the high speed of Yuchu, the 90 tunnels along the line have their own characteristics. During the promotion of the cave door landscape, they fully integrate the local ethnic minority customs and personalities and characteristics, and realize the characteristics of one tunnel. "There are many ethnic minorities including Yi, Bai, Dai, Hui, Hui, Miao, Miao, Dai, Zhuyi, Hani, Hani, and other ethnic minorities. Four forms such as painting, plastic stone, and real stone lacquer to improve the landscape of the cave door. "Wei Chu, the chief engineer of the Yuchu high -speed project of China Railway Construction Industry Group, introduced. In order to fully protect the local ecology, after the construction of 31 high pools along the line, the project department recovered the destruction of vegetation to its original state in time. At the same time, the flowers and plants in front of the cave door were carefully arranged. It's even more ingenious. "The greening area of the Jade Chu project has a total of 420,000 square meters. During the rainy season, we seize the time to plant the peed -bean plants that are easier to survive, reducing the cost of pipe raising. At present Liu Dengkui, Secretary of the Party Branch of the Chu Expressway TJ-9 bidding project.

The reporter learned that during the construction of Yuchu's high -speed speed, Yishan took the momentum and borrowed scenes to create more than 700 acres of soil farms to re -reclamation and greening. Now the original barren mountains and deserted beaches are covered with green. The abandonment farm has also become a fertile farmland. Last year to this year, local farmers have grown several crops. While comprehensively improving the ecological and ornamental of the environment along the transportation, it also lays a solid foundation for rural revitalization and creating conditions.

On the day of opening the traffic, Mr. Zhou and friends who run business between Chuxiong and Yuxi all year round took the lead in experience the whole process of Yuchu high speed. The schedule that had been running for nearly 4 hours now only takes one and a half hours to reach. Mr. Zhou believes that after the opening of this highway, it is very convenient for the people along the route to travel, which is very good for the development of the two places.
