The world’s first four-line high-speed railway turntable steel box girder truss bridge has successfully rotated into place in Anhui Province, marking a significant milestone in China’s railway infrastructure development. According to IT Home on September 2, the bridge, part of the Hefei-Xinyi railway project, completed a 67-degree clockwise rotation in 56 minutes, providing a solid foundation for the smooth connection of the railway.
Location and Dimensions
The bridge, which spans across the Beijing-Shanghai High-Speed Railway, is located in Dingyuan County, Chuzhou City, Anhui Province. With a total length of approximately 4.6 kilometers, the bridge features a steel box girder truss combination beam that extends 146 meters in length and 25.4 meters in width. This unique structure supports four railway lines, making it the world’s first of its kind.
Construction Challenges
The construction process of this bridge posed several challenges due to its proximity to the operational Beijing-Shanghai High-Speed Railway. The steel truss girder was assembled parallel to the existing railway lines, which increased the risk of accidents during the construction and高空 operations. The complexity of the full-welded construction technique and the rotation process required high precision and stringent quality control measures.
The bridge’s installation demanded meticulous attention to detail, particularly in ensuring the accuracy of the steel truss girder placement and the quality of the welding. These factors made the bridge one of the most challenging projects within the Hefei-Xinyi railway project.
Project Overview
The Hefei-Xinyi High-Speed Railway, which is a key component of China’s railway expansion plans, originates in Hefei, Anhui Province, and traverses through several cities and counties, including Dingyuan County, Fengyang County, Mingguang City, Wuhu County, Sishui County, Siyang County in Jiangsu Province, and finally terminates in Xinyi City. The entire route spans approximately 324 kilometers and is designed to operate at a maximum speed of 350 kilometers per hour.
Significance and Impact
The successful rotation of the bridge is a testament to China’s engineering prowess and its commitment to developing state-of-the-art infrastructure. This innovative bridge design not only ensures the efficient integration of the Hefei-Xinyi railway with the existing Beijing-Shanghai High-Speed Railway but also minimizes disruptions to train services during the construction phase.
The bridge’s completion will significantly enhance the connectivity between the cities along the railway line, fostering economic growth and facilitating the movement of goods and people. It is expected to improve the overall efficiency of the railway network and contribute to the regional development of Anhui and Jiangsu provinces.
Future Prospects
With the successful installation of the bridge, the Hefei-Xinyi High-Speed Railway project is one step closer to completion. The railway is set to become a vital artery in the national transportation network, supporting the country’s economic growth and enhancing its global competitiveness.
The completion of this project will also pave the way for future railway infrastructure developments, pushing the boundaries of engineering and innovation. As China continues to invest in its railway network, projects like the Hefei-Xinyi railway will serve as a benchmark for excellence in engineering and construction.
In conclusion, the successful rotation of the world’s first four-line high-speed railway turntable steel box girder truss bridge in Anhui Province is a remarkable achievement that showcases China’s engineering capabilities and its dedication to developing sustainable and efficient transportation infrastructure.
