The Beipanjiang Railway Bridge is an arch bridge over the Beipan Jiang Gorge around 44 km south of Liupanshui in the Chinese province of Guizhou .
It is the largest of the approximately one hundred bridges of the Shui-Bai Railway , which was opened in 2001 to develop coal reserves, improve the transport infrastructure and promote economic development in one of the poorest provinces in China.
description
The single-track railway bridge crosses the Beipan Jiang at a height of 275 m. It was the highest arch bridge and the highest railway bridge in the world and after the Liuguanghe Bridge, which was completed in the same year, the second highest bridge ever. It relegated the New River Gorge Bridge as the highest arch bridge since 1977 and the Mala-Rijeka Viaduct as the highest railway bridge since 1973 in second place. In the meantime, a number of higher bridges have been built in China, most recently the Beipanjiang Bridge (Hangzhou-Ruili highway) as the highest bridge ever and the Qinglong Railway Bridge, which also crosses the Beipan Jiang, as the highest railway bridge (if one considers the Najiehe Railway Bridge , which leads over a reservoir disregards).
The Beipanjiang Railway Bridge is a CFST bridge with an overhead track and a span of 235 m.
The arch consists of two ribs with 4 steel tubes each, which are connected to one another by a steel tube framework. The two ribs are inclined to one another with respect to the vertical, so that they have a broad base at the base of the arch. As usual, they were not erected in a cantilever with auxiliary bracing. Instead, the two halves of the arch were mounted on the side of the slopes and then swiveled over the gorge until they met in the middle. The two rotating bases were then concreted into large abutments . After assembly, the pipes were pressed with concrete from below, which stiffened the arch after it had hardened and increased the load-bearing capacity of the bridge structure.
The deck is wide enough to accommodate the gravel bed and sidewalks on both sides, which are also used by the local population.
At the western end of the bridge, the railway disappears into a tunnel, from which it emerges again after a loop high above the tunnel entrance on a slope bridge. Next to it runs a slope bridge on the Shuipan Expressway , which is connected to the 155-high Laoyingyan Bridge just under a kilometer to the south . Three kilometers further north, the Shuipan Expressway crosses the Beipan Jiang on the Beipanjiang Bridge (Shuipan Expressway), which was completed in 2013 .
In the photos, deep down next to the bridge, you can still see the 200 m long rope bridge on which the construction workers crossed the gorge. It consisted of six parallel wire ropes covered with wire netting and boards, and railings made of two ropes and wire netting. It has since been removed.
