As the first -class star project of the Jining City Hanging Chart, the new airport high -speed project is currently progressing smoothly. It is planned to be opened to traffic in December 2022. After the opening of the traffic, it will effectively connect important transportation nodes such as Jining Daan Airport, Lunan High -speed Railway Jining East Station, and high -speed road network trunk lines such as Rilan Expressway and Zaohe Expressway to form a three -dimensional transportation network. The integrated development of the circle and the Lunan Economic Circle is of great significance.

The starting point of the new airport high -speed project is located in Xinyi Town, Yanzhou District. It is 59.7 kilometers in the south of Luzhou District, High -tech Zone, Zoucheng, and Weishan County. The entire line adopts a two -way four -lane highway standard with a design speed of 120 kilometers per hour. It is understood that the geological conditions of this project are complicated, crossing the river, crossing the railway, the viaduct accounts for 64.3%, and there are 2 echo bridges and 13 large and middle bridges. In addition, the project line is long, there are many construction points across the road and cross -river construction, and it across the country's provincial highway 9 times.

In the early morning of July 11, the important control project of the new airport high -speed project, the transition of the Xinxin Railway Bridge, successfully turns. It is understood that the total length of the transition bridge across the Xinxin Railway is 170 meters long and the total weight is 29,000 tons. It is currently the largest span and the most heavier T -structure highway rotary bridge in the province. The main bridge adopts a 2 × 85 meter prestressed concrete T -shaped steel structure, and the upper structure is a fully prestressed concrete transforming cross -section box beam. The seat uses 60 tons and a model of 330mn. It is the newly -has the largest radius and the most important tonnage in the province. The project is close to the Xinyan Railway and National Highway G327 transportation line. The construction venue is limited and the surrounding conditions are complicated. Among them, the average daily traffic of the Xinyan Railway is about 230 columns, and the operation business is busy. In order to firmly grasp the iron -related construction window and accelerate the progress of construction, the construction party effectively expands the construction work surface, reduces the time of turnover, and guarantees the construction efficiency and construction progress. At the same time, the construction organization is optimized according to the progress of the project and the capacity of production capacity, and the construction of the paddling section is simultaneously reduced, which further reduces the construction period. With the successful turn of the Xinyan Railway Bridge, the project construction has entered the sprint stage of the decisive battle.

The Baima River Bridge, located in Weishan County, is another control node project of the new airport high -speed. It has also successfully completed the dragon at the end of June, creating conditions for the completion of the project at the end of the project. The Baima River Bridge is 1460 meters long and the main span is 240 meters. It is the largest central double cable dwarf tower with the largest span in Shandong Province. Since the resumption of work in the bridge, the construction unit has adhered to the prevention and control of the epidemic and the construction of engineering construction. It has adopted measures such as preparation of epidemic prevention supplies, designated and drop -off of labor personnel, and closed management of construction areas to ensure the smooth construction of the project; The power of the construction personnel, the steel box beam assembly adopts welding robot technology, and does not stop working for 24 hours to ensure the quality and progress of welding. The construction of Heilong is completed 15 days in advance compared to the original plan.

"In the next step, it will further increase the investment in production factors, adhere to the prevention and control of the epidemic, the construction and production of the“ two -handed grabbing, and the two mistakes', and to launch a comprehensive sprint to the target of the traffic during the year. Yan Zongyao, director of the Jining people. "Yan Zongyao, director of the engineering department of Jiwei Project Company.

The reporter's speech: Highway traffic is the most widely covered way, the most service population, and the most widely used transportation method. After the completion of the new airport at high speed, it will further improve the traffic road network of our city, enhance regional transportation advantages, provide important support for economic and social development, and promote the transformation and upgrading of the industrial structure of Jining, expanding the opening of the outside world, promoting high -quality development of regional economic and social, and the development of tourism resources. Positive effects. (Reporter Xu Fei)
