On August 31, the last section of steel box girder was erected, marking the connection of the Fuchunjiang River Bridge, an important part of the Huhang Railway which is the guarantee project of the 2022 Hangzhou Asian Games. The bridge was partly undertaken by China Railway Shanhaiguan Bridge Group.
The Fuchunjiang River Bridge is the first higher-lower tower cable-stayed bridge in China, with the 300-meter-long single span, designated speed of 350 km/h, 4-line ballastless track, H-shaped main pylon, steel-concrete main girder, and a total length of 535.4 meters.
The Fuchunjing River Bridge is successfully connected.
RBG is responsible for the manufacture and installation of the steel pylons and box girders, which is hard to meet the quality standards and tackle the technical challenges.
Despite of the difficulties such as transportation during the flood season, linear control of steel box girder, heavy section lifting, complex manufacturing processes, and limited time, they completed the bridge on time.
The Fuchunjing River Bridge.
They have prepared the closure parts on the measurement of steel beam line type, mileage elevation, and ring opening matching degree, and the calculation of the temperature influence on the steel beam.
They started at 4 am on August 31, and completed the hoisting in a perfect way within only 5 hours, which laid a solid foundation for the closure of the main bridge.
The Huhang Railway is a key supporting project for the Hangzhou Asian Games, a component of the intercity railway network in the Yangtze River Delta, and a key project to realize the 1-hour traffic circle in Zhejiang Province.
The Fuchunjiang River Bridge is expected to be completed and opened to traffic before the 2022 Asian Games.
