With the development of China's highway, single column pier prestressed cover beam will be widely used in highway bridge project. But for the terrain, geological conditions of the complexity of the tall single column pier prestressed cover beam, if the conventional bracket method (steel pipe frame method) construction, there is a series of problems such as high investment, long cycle, technical difficulties. To this end, the author combined with Chang (De) Zhang (Jiajie) highway dog beach bridge project construction, recommended the introduction of bracket supporting mold technology in a single pier prestressed cover beam construction and construction process, can be similar to the future bridge project construction to provide technical reference.
