The "Mysterious Vellet" southern section of Xi'an Outer Ring Expressway gradually opened

On August 31, the rain was sunny. The new asphalt pavement on the southern section of the Xi'an Outer Ring Expressway shines against the blue sky and white clouds. All the way passed through Lantian South Lidou, Bailuyuan Tunnel and Luohe Bridge, and finally arrived at the Ziwu service area that was being improved.

On August 31, the Xi'an Outer Ring Expressway Lantian South Hub at the corner of the drone passed.

Live: "brand -new" and "convenient" show everywhere

With August 25, the good news of the road, road, and traffic safety projects of the southern section of the Xi'an Outer Ring Expressway, and the good news of the successful passage of the handling of work. It's getting closer.

On August 31, the reporter followed the staff of Shaanxi Traffic Control Group to step on the points in advance of the sections of the project.

At 9:50 in the morning, the reporter came all the way to the south section of the Xi'an Outer Ring Expressway. The flat ground, green fence and white marking lines set off the blue sky and white clouds that day, which shows "new" and "convenient" everywhere.

The reporter saw that after the completion, there were 8 ramps that could be interconnected with Fuyin High Speed. It was the largest interchange in the southern part of the high -speed high -speed high -speed high -speed high -speed high -speed high -speed speed. The overlap has been completed and passed through the work and acceptance. At present, there are only some fragmented devices left at the scene. After opening to traffic, starting from the four directions of the surrounding areas will greatly shorten the previous traffic time.

The vehicle continued to drive forward and arrived at the White Deer Plain Tunnel more than ten minutes. The total length of the tunnel is 2819.5 meters (double hole), the excavation width is 18.7 meters, and the excavation section is 192.3 square meters.

"The Bailuyuan Tunnel entered the cave construction in May 2018, and it went through in July 2021. It was very difficult during the construction process." At the scene that day, the relevant person in charge of the project introduced that the geological and hydrological structure of the White Luyuan tunnel was complicated, and the geological diseases were frequent. The water content of surrounding rocks is large, the soil is severe, and the construction safety risk is extremely high. Facing the complex geological and hydrological environment, the project adopts a variety of construction techniques and technical research, and assumes the research tasks of the construction of the "Ping An Centennial Quality Project" of the Ministry of Transport's "Ping An Centennial Quality Project", which ensures that the construction difficulties have been passed smoothly.

Subsequently, standing on the Bridge of the Luohe River overlooking the distance, the mountains of the Qinling Mountains were clearly visible, and the scenery of Bailuyuan was full of views. The reporter learned that as the control project of the project, the Luohe Bridge is the only continuous rigid bridge across the board. The bridge is 2266.5 meters in length and the maximum of 65 meters in the pier. In the future, the West Tenth high -speed rail will pass by.

Looking forward to: "Internet celebrity" service area can satisfy food, accommodation, travel, travel

During the construction of the southern section of the Xi'an Outer Ring Expressway, the Ziwu service area that had not yet been "exposed" has already become the "Internet celebrity" service area that everyone is looking forward to.

It is understood that in order to improve the quality of quality and work in the service area, and to achieve new concepts such as "integrated travel", "service area+", and "smart service areas", the Xi'an outer ring high -speed project is based on the operation experience of foreign provinces. The unique geographical advantages of the Guanzhong Ring Road will build the Wuwu service area as a multi -business modern business sharing service area.

On August 31, the construction of the Xi'an Outer Ring Expressway in the construction.

In the specific construction, the project relies on the construction of Sanhe and Yishan Greenway in Xi'an, and positions the Ziwu service area as the first sports service area in Shaanxi and mountain parks under Qinling Mountain. On August 31, the reporter saw in the Wuwu Service Area that the two -story building has been fully built, and the scene was busy. Many workers on the service area square were hardening the ground.

"At present, the main construction of the main body is basically close to the end, and some of the peripheral repair and improvement projects are currently underway. There are already more than 30 merchants including catering and entertainment entering the decoration stage. Most of the decoration progress is about 60%. . According to the plan, the service area will enter the status of comprehensive cleaning, commissioning and trial operation after September 15. After completion, it can meet everyone's needs for eating, accommodation, travel, and entertainment. "Yang Weizhong, deputy general manager of Shaanxi Traffic Control Service Management Group, introduced The project breaks the tradition of closed service areas, realizes connecting with the Guanzhong Ring Road, and drives the overall economic chain of the highway "integrated and shared service areas".

After completion of the sub -service area, the south and north areas will be connected across the main line with a 708 -meter -long slow lane. It is also available for tourists to walk and cyc up. At the same time, the Wuwu service area is also connected to He Zilu, and the integration of the Xi'an Sanhe Yishan Greenway System will become the only choice for the citizens to close the Qinling Mountains and enjoy the natural scenery of the plain countryside.

Difficulty becomes highlights: 3D "printing" for the first time on the road construction

The reporter learned that during the construction of the southern section of the Xi'an Outer Ring Expressway, it encountered a lot of "block tigers" in the process of construction.

For example, during land acquisition and demolition, the development zone, enterprises, villages and towns along the project, densely demolished and resettlement workload; environmental protection, the project is located in the Qinling Ecological Reserve, the ecological environment is fragile, the environmental protection construction and green operation requirements are high; Crossing Qinhu Road, Xizheng Road, Ziwu Avenue, Changan Avenue, Yan Yin Road, S107 Provincial Highway and other local main roads, and cross -high highways are crossed. All the participating units focusing on the traffic targets, under the premise of preserving quality and safety, overcoming various constraints such as the prevention and control of the epidemic, environmental protection, etc., fighting day and night, and setting off a large boom. In the process of solving the problem, many industry leaders and "traffic control manufacturing" have also been created.

The reporter learned that during the construction process, "traffic control manufacturing" such as scientific research products and dual -component high -light scraping lines was used. At the same time, for the first time, the net -flavored environmentally friendly asphalt material was applied to the construction of highway in the province. In addition, in pavement of pavement, for the first time, I tried 3D pavement and asphalt pavement unmanned smart construction technology, realizing the concept of "mechanized substitution and automation reduction", which greatly improved production work efficiency.

Zhang Gaoke, the project manager of the ZS-1 contract section of Xi'an Outer Ring Expressway, introduced that the 3D paving technology is the high-primary accuracy and flat accuracy of the stereo-to-pavement through the global navigation positioning system and the laser high-precision measurement system of satellite. "It is equivalent to performing 3D‘ print ’on the pavement. The flat accuracy error can be controlled at about 3 mm.” This technology avoids artificial errors to the greatest extent. At the same time, the concept of "mechanized substitution and automation reduction" has also been realized, which has greatly improved production work.

The asphalt pavement unmanned smart construction technology is based on the integration of Beidou high -precision positioning, inertial navigation and radar sensing. It can control up to 20 devices through a operating interface. Unmanned driving of equipment and other equipment.

In addition, the project also explores the application of Internet+construction project management model. With the "Traffic Control Changan Information Management System" as the platform, it has developed and applied 26 subsystems of 7 informatization systems. At present, 2 invention patents have been obtained. Items, 16 software copyrights.

Key projects have been basically completed and opened to traffic before September 30

Xi'an Outer Ring Expressway is an important part of the province's highway network planning. The Xi'an Outer Ring (South Section) project starts in Guzi 硙, Qiyi District, Xi'an City. It can run a total of 103 natural villages in 17 streets in three districts (counties) in Xi'an High -tech Zone, Chang'an District, and Lantian County. High -speed Lantian east side of the east side.

The main line of this project is 70.16 kilometers in length. It uses a two -way six -lane highway standard design. The design speed is 120 kilometers per hour, and the overall roadbed width is 34.5 meters. There are 11 interchanges of each other. The roads of major cities achieve high standards.

"The projects, bridges, tunnels, roads, traffic, and mechanical and electrical projects have been basically completed. It is planned to be completed and opened to traffic by September 30." Zhang Xiaofeng, the head of the southern section engineering department of Xi'an Outer Ring Expressway. The large ring line of 270 kilometers in Xi'an, such as the northern section of the outer ring high -speed speed, can timely divert trucks and transit vehicles in a timely manner, which greatly alleviates the pressure of high -speed transportation by Xi'an by the city, and promotes the smooth and smooth traffic around the city.

At the same time, the reporter learned that the project connects the four national highway networks of Beijing -Kunming, Bao Mao, Fuyin, and Shanghai and Shaanxi, and is connected to the highway such as Zhoumei and the upcoming West High -tech to Tianqiao. Quick conversion, convenient for the masses, encrypted the province's highway skeleton, build a comprehensive transportation system in Da Xi'an, and the development of skeleton in the Sabinan is of great significance.
