According to the design drawings, the main span of yangbaoshan super major bridge is 650m single span steel truss girder suspension bridge, and the main cable side spans are 170m and 210m respectively; The middle span of the main cable is 650m, the vertical span ratio is 1 / 10, the central chainage of the main bridge is K40 + 626, and the whole bridge is 1112m long.
The project took the lead in erecting the main cable by “air spinning method” in China for the first time, but there was no design and construction experience in this regard.
On the afternoon of August 31, the construction of yangbaoshan bridge, the control project of Guiyang Huangping Expressway (Guiyang Huangping Expressway) of Guizhou Expressway Group PPP project, was completed.
The bridge crosses the dumuhe Grand Canyon.
It is the most convenient Expressway from Guiyang to the Yangtze River Delta Economic Zone in the East.
According to the construction data drawing, the Guiyang Huangping expressway project starts from Yongle Township, Nanming District, Guiyang City, connects with Jianxiao expressway, passes through Wudang District, Longli County, Guiding County, Fuquan city and Huangping County, and ends at Yukai expressway.
This technology has completed more than 20 technical patents.

All these B & B are available! Announcement on public selection of civil servants by organs directly under Guizhou Province in 2021 (attached with position table)..
This is another control project of Guihuang expressway, and the construction is completed smoothly according to the planned nodes.
After the completion of the project, the distance from Guiyang to Huangping will be 39 km shorter than guiweng Expressway and 60 km shorter than Shanghai Kunming expressway.
This technology can effectively solve the main cable erection problems of mountain suspension bridges with poor transportation conditions and super long span (more than 2000 meters) and continuous long-span suspension bridges, and has the characteristics of low cost, strong applicability, intelligence and high degree of automation.
The main line of the project has a total length of 120.6km and a design speed of 100km / h.
The completion of the construction of yangbaoshan bridge means that we are further away from the opening of the whole line of Guihuang project! Are you looking forward to it?
