Sichuan'S Guangzhou Shaanxi High-Speed Line Runs Through &Nbsp, And Is Expected To Open To Traffic In May.

The wide pass of the Guangzhou Shaanxi Expressway provides a site for pavement construction and ancillary works, and lays the foundation for the completion of the whole line in May.

In April 1st, the head of the Limited by Share Ltd of the North Sichuan Expressway told reporters that in the morning of March 31st, with the closure of the T girder of the Guang Shan high speed porcelain paving bridge, the Guangzhou Shaanxi Expressway was fully connected.

A total length of 58.9 kilometers to build 6 overpasses.

The Guangshan expressway is the capital radiating line of the national expressway network. The G5 Beijing Kunming Expressway (Beijing to Kunming) is the northernmost part of Sichuan. The North Ningqiang highway from Shaanxi to Chesson pass West Han highway passes through the neutron, Xuan River, Chao Tian, Shahe and porcelain kiln shops. It is located in the Jialing River of Guangyuan city and the south Guangdong Guangyuan highway to Mianyang, with a total length of 58.9 km.

Among them, the checkerboard is about 30 km from the building ditch section, and adopts the new scheme, and the building ditch to the Jialing River section is about 28.9 kilometers.

The section is an important hub for Sichuan connecting northwest and North China and an important access to Sichuan.

The standard construction of two-way four lane expressway is adopted on the whole line of the Guangzhou Shaanxi Expressway. The design speed is 80 kilometers per hour and the width of the roadbed is 24.5 meters. The reconstructed section uses the existing highway as the separate roadbed, and the width of the roadbed maintains 12 meters.

Asphalt concrete pavement.

In the 6 places such as neutron, Chao Tian, Lou Gou, Shahe, porcelain kiln and upper west dam, interchange is set up, and the interchange of Ling Jiang is extended and expanded. There are 1 Main toll stations and 6 ramp toll stations.

Complicated geological structure and 6 tunnels

In order to alleviate the traffic pressure of the two special roads in the Guangbei section and ensure the normal traffic of vehicles entering and leaving Sichuan and Shaanxi, the builders of the Guangzhou Shaanxi Expressway set up a "military order", and at any cost, they scramble the 1.5 km section of the chessboard before the Spring Festival in 2010.

Because of the difficulty of road construction and the number of bridges and tunnels, the construction workers gave up the holidays and worked overtime for 24 hours to make the chessboard pass 10 months ahead of the expected completion time.

The traffic from Shaanxi to Sichuan after the opening of the section is made up of

In June 13, 2010, the 6 tunnels of chessan pass tunnel, Qinglin slope tunnel, ancient Jiashan tunnel, Mingyue gorge tunnel, Feixianguan tunnel and cuijiya tunnel all pass through.

The ancient Jiashan tunnel is 2100 meters long. The tunnel is mostly lava. The geological conditions are very complex and the speed of excavation is very slow. Since its construction in April 2008, the builders of the tunnel have overcome many difficulties such as the "5. 12" earthquake. It took 25 months to "bite" the "hard head".

After the completion of the operation, the north gate will no longer be blocked.

"Mianyang Guangzhou Expressway two special line traffic pressure is particularly large, almost every day there are varying degrees of vehicle detention and vehicle wiping."

Yuan Ming, deputy commander of the two special line traffic police brigade of Mianyang Guangzhou expressway, said that after the "5. 12" earthquake, the traffic volume of two special roads in Guangbei increased sharply, and the average daily traffic volume increased to more than 40 thousand vehicles.

After the opening of the Guangzhou Shaanxi Expressway, it will completely solve the serious overloading pressure on the 108 North Road two line north of Guangyuan.

Assistant General Manager of the North Sichuan Expressway Limited by Share Ltd, Fujian, said that the Guangzhou Shaanxi Expressway is one of the 12 import and export channels for highway traffic construction in Sichuan province. It will also be the first highway tunnel in Sichuan (except Chongqing) built in advance by Sichuan. According to the requirements of the provincial Party committee, the provincial government and the Provincial Transport Department, the whole line will strive to be opened to traffic in May.
