| Abstract: | The first unit of Zhengzhou Yellow River rail cum road bridge is a six pylon and single cable plane cable stayed continuous steel truss girder bridge. The schemes for the erection include cantilever erection with gantry crane or girder erection crane, and pushing for installation. Through comparison and research of different erection schemes, it is determined that the first unit of the girder is to be erected by the multi point longitudinal hauling scheme. |
