The official name of Fengshuba Bridge is Dongjiang Pengkeng Bridge. It is an auxiliary project of Fengshuba Hydropower Station. The bridge is located in Pengkeng, the ancient city of Fengshuba, hence its name. just a few hundred meters from the dam, from the bridge you can have a panoramic view of the power station dam. The north and south ends belong to Chiguang Town and Yan Town, Longchuan County. Before the Lizui Dongjiang Bridge was completed and opened to traffic in 2003, it was the mouth of the former Longjiang (West) Expressway.
Pengkeng Bridge is the second T-shaped rigid frame bridge completed in 1975. It is the first road bridge located in a reservoir in Guangdong Province, with a total length of 301 meters. It consists of a two-hole double-curvature arch bridge of 28 meters and 64 meters and two pre-stressed T-shaped rigid frames andof suspended beams. The two rigid T-shaped structures span the main channel of the river. Since the normal water level under the bridge after impounding the reservoir is 62 meters deep, the main pier is 65 meters high. It is the first pre-stressed concrete T-shaped cantilever cast. rigid structure built in Guangdong province. Road bridge with high piers. The foundations of the bridge's two piers use reinforced anchors rather than embedded rock. Walking across Fengshuba Bridge, you can hear the roar of water flowing from the dam. Looking at the turbulent river surface, it is like a stream. Not only is it exciting, but it also makes people very proud.
The length of the T-shaped rigid frame cantilever is 29.6 meters, and the box girder section is made of a single box and a double chamber. There are 114steel wire bundles arranged on each T-shaped rigid frame cantilever beam., of which 60 bundles are anchored at each joint section. On the upper plate, there are 54 beams fixed to the ribbed plates of each joint section. The vertical prestressed plates are arranged in the center of the ribs, and the transverse cables in prestressed steel. are arranged on the cantilever beams to improve the bearing capacity of the cantilever beams and increase safety.
The bridge was originally planned to be completed and opened to traffic in 1971, in synchronization with the water storage and power generation of Maple Dam Reservoir. However, due to the collapse of the north end (bridge without arch). part), as it was nearing completion, this section was redesigned and built by another engineering firm, the arch bridge at the south end is partially preservedand it is a rare “one bridge, two systems” bridge. The entire bridge was not completed until 1975, during which time passing vehicles and people were transported by ferry.
