Jiantan Dongjiang Super Bridge
The Jiantan Dongjiang Grand Bridge is a railway bridge located in Huicheng District, Huizhou City, Guangdong Province, China. It is one of the river-crossing bridges on the Beijing–Kowloon High-Speed Railway (the Ganzhou–Shenzhen section), situated to the west of Jiantan Village in Huizhou’s urban area, directly above the Dongjiang River channel. The bridge is currently one of the largest‑span and widest ballastless‑track cable-stayed bridges with a tower‑pier‑girder integral system in China, with its main span… 260 meters, with a main bridge length of 532 meters. The bridge has a transverse width of 31.2 meters and serves as a large-scale, four-track railway crossing over the river.
The Jiantan Dongjiang Grand Bridge is a prestressed concrete short‑tower cable‑stayed bridge with a span arrangement of 136 m + 265 m + 136 m. The stay cables are available in two specifications—15.2‑91 and 15.2‑109—with a total of 40 cables. It is currently the world’s widest four‑track railway cable‑stayed bridge featuring the largest‑specification stay‑cable anchorages. Each set of cable anchors is equipped with an optical fiber grating cable force monitoring system, comprising 80 sets in total, and the project utilizes 943 tonnes of epoxy‑coated steel strands. Our company is responsible for supplying the stay cables and providing installation services.
