Zhengyu High -speed Railway Open Operation

Correspondent Wang Feihui Zhang Xin Hao Ce

On June 20, the establishment of the Zhengzhou high -speed railway Xiangyang East to Wanzhou (hereinafter referred to as the Zhengyu high -speed rail Xiangwan section) was completed and opened, marking another fast way to go out from China Railway Construction to participate in the design, supervision and construction of my country. Passenger Channel -Zhengyu High -speed Railway has achieved the entire operation of the entire line. The fastest 6 hours 46 minutes, 46 minutes, 4 hours and 23 minutes in Chongqing from Beijing, Zhengzhou to Chongqing can be reached.

The Zhengyu High -speed Railway is located in the provinces of Yu, Hubei, and Chongqing, with a total length of 1068 kilometers. Among them, Wanzhou north to Chongqing section and Zhengzhou east to Xiangyang East section have been opened in November 2016 and December 2019, respectively. Zheng Wan Duan, which was opened to traffic this time, from Zhengzhou East Station to Chongqing Wanzhou North Station. It has a total length of 818 kilometers and has 18 stations with a design speed of 350 km/h. Construction started in December 2016.

The new line of the Zhengyu high -speed rail through the mountain through the tunnel, the mountains along the route are deep, the line -to -bridge tunnel ratio is as high as 98%, the terrain and localforms are complex and changeable, and geological disasters such as rock -soluble and landslide often occur.

Nanyang East Station, designed by the Fifth Court of Railway Courtyard and the construction of China Railway construction, is currently the largest domestic passenger high -speed railway station in China. The design is based on the concept of "Wolong Tengfei, Fun Niu Ending". The "shuttle" sunroof adopts the image of "Kong Ming Lantern", making Nanyang's historical and cultural heritage out.

The China Railway Eleven Bureau invested more than 10 advanced tools, and used the "Mechanical Corps" to overcome the heavy difficult engineering people and tunnels who were known as "below the tunnel". They set up a technical research and development center to overcome the domestic high -speed rail first deep water pile base bridge and the largest steel coffin construction problem across the board, filling a number of technical gaps such as my country's high -speed rail deep -water infrastructure construction. In the construction of the Luojiashan Tunnel of the Special Tunnel of the Special Tunnel, China Railway Twelfth Bureau realized the first time the high -speed railway mountain ridge tunnel was mechanized to mechanically break the safety, high -quality, efficient, and intelligent construction, becoming the most mechanized and most widely used "model model in domestic high -speed rail tunnel construction construction. "project.

The automatic detection system independently developed by China Railway Seventeen Bureau is the first in China. The use of automatic maintenance water circulation system, wide use of modular and assembly steel structures, etc., can be used to achieve cost reduction and efficiency. In the construction of Huangjiagou Tunnel, the longest tunnel of the 6th standard tunnel of Zheng Wan Wan's high -speed rail, the Sino -Wan Wan High Speed ​​Rail Tunnel was used to successfully solve the four non -performing geological construction of the soft rock large deformation tunnel of the soft rock large deformation tunnel. The problem is to achieve the safety of tunnels. They took the lead in the 6th bidding track period, and their independent innovative track fasteners were authorized by the national utility model patent, which has accumulated valuable experience for similar orbit construction.

The Zhengyu high -speed rail is an important part of my country's "eight vertical and eight horizontal" high -speed rail network. After the entire line is opened, it will further improve the structure of the rapid railway network in central and southwestern my country, which will greatly facilitate the travel of the people along the line, promote the development of tourism resources and industrial development. Significance.
