The design speed is 350 kilometers per hour, and the newly -built intercity railway in Anhui began to stand

On August 1st, at the construction site of Jiangxinzhou Tour Bridge of the Chaoma Intercity Railway, the Changjiang Gong Railway Bridge, a high -speed rail double -line beam with a total weight of 930 tons and a beam of 40.7 meters has been steadily landing on M84 and M85 Dunzhi. Above the seat marks the success of nearly a thousand tons of "oversized box beams" in the nest of the Chaoma Intercity Railway, and the construction of the project has entered a new stage of the construction of the beams.

The main length of the Chaoma Intercity Railway is about 76 kilometers. It is located in Anhui Province. The line is from Chaohu East Station. It via the new district of Hanshan County and Zhengpu Port in Maanshan City. There are 5 stations in Chaohu East, Hanshan, Zhengpu Port, Ma'anshan South, and Ma'anshan Shandong. The 40.7 -meter box beams set up in this time are grown -up beams. Due to its characteristics of large spans, large volumes, large anchors, etc., the deformation of the installation equipment and offline basic force of the transportation frame, and The process methods such as stretching slurry, storage of lifting, and transportation racks have put forward higher requirements.

"Chaoma Intercity Railway spans the Yangtze River, and the bridge area is a flood discharge area. The foundation of the foundation is high. The use of a 40.7 -meter large span railway beam beam can effectively reduce the streaming and reduce the coexistence point of the bridge pier Open smoothly to improve the quality of high -speed rail transportation services. "China Railway Shanghai Bureau Group Co., Ltd. Ning'an Railway Company Ma'anshan Changjiang Bridge Commander Zhang Wenbo, deputy commander of the headquarters.

"The first box beams set up this time are much larger than the traditional 32 -meter standard box beam. It is also adopted for the first time in the construction of high -speed rail in Anhui Province. In the construction, the largest tonnage high -speed rail beam machine is used in my country to use it." Zhou Qingyong, manager of the 3 -bid project of Chaoma Intercity Railway in China Railway, introduced.

In order to ensure the successful settlement of the first box beam, China Railway Shanghai Bureau Group Co., Ltd. coordinated the construction and supervision of the participants to carefully arrange and carefully arrange them, and summoned special meetings many times to scientifically formulate planning plans, safety measures and emergency plans; nearly 200 on the spot; Famous builders overcome the recent rare high temperature and hot summer effects, continue to attack, while "iron" to fight "iron", make various construction preparations in advance, match with strong resources, standardize operation procedures, ensure the safety of the process of the first box beam beam beams, smoothly.

The Chaoma Intercity Railway north connected to the Hangzhou High -speed Railway, the inter -urban railway of the south of the Jiangsu Jiangsu, which is not only the direct connectivity of Ma'anshan and the provincial capital Hefei, but also a new channel for high -speed railway to the Yangtze River Delta cities such as Anhui to Shanghai. After the opening of this railway, it is of great significance to further improve the regional high -speed railway network layout, enhance the transportation capacity of the channel, and promote the development of the Yangtze River Delta and the development of the Yangtze River Economic Belt.
