Background
In recent years, the construction of propulsion traffic infrastructure is accelerated in China, mountain roads and deep water engineering projects in construction projects are increased, and the proportion of road bridge tunneling projects is increased. In order to ensure that design indexes such as plane linearity, longitudinal slopes and the like meet the requirements of high-grade highways, the number of high pier bridges in many projects is increased, and the pier heights are continuously increased and increased. Particularly, the method has more and more application requirements in areas with large relief fluctuation, such as mountain areas, mountain areas and the like. The construction of the high pier of the bridge has the characteristics of high construction difficulty, multiple construction influence factors, long construction period, high construction technology and construction quality requirements and the like. Most of the high pier construction technologies are applied in an overhead working state, so that the construction difficulty is greatly increased, and constructors have high personal safety risks, which are main factors for causing the high pier construction specificity. The prior bridge high pier construction mostly adopts a climbing formwork technology, but for the higher bridge high pier, a double-limb high pier structure is generally adopted, namely, two mutually parallel high piers are arranged on the same section of a road, and a plurality of transverse tie beams are designed between the high piers for enhancing the structural stability between the high piers, but the side structure can further increase the technical difficulty of on-site integrated construction, and the prior climbing formwork equipment can generally only finish the construction of the high piers first and then cast the transverse tie beams, so that the construction period is longer.
