On the morning of August 1, 2022, a prefabricated box girder with a length of 40.6 meters and a weight of nearly 1,000 tons was successfully erected on the Chaoma Intercity Railway, which is currently the longest railway prefabricated box girder in Anhui. So far, the project construction has entered a new stage of beam construction.

According to the relevant person in charge, the Chaoma Intercity Railway spans the Yangtze River, and the approach bridge area belongs to the flood discharge area, and the bearing capacity of the foundation is high. The use of long-span railway simply supported beams can effectively reduce the flow resistance and reduce the pier connection resonance point, allowing high-speed trains Achieving higher running speed, this is also the longest railway prefabricated box girder erected in Anhui Province.

The main line of Chaohu-Ma'anshan Intercity Railway is about 76 kilometers long. It leads from Chaohu East Station and crosses the Yangtze River to the south of Ma'anshan. The designed speed is 350 kilometers per hour. It is connected to the Shanghe-Hangzhou Railway in the north and the Intercity Railway along the Yangtze River in the east. It is a direct link between Hefei and Ma'anshan. After completion, it will become an important part of Hefei's one-hour commuting circle.Editor/Ma Xue
