摘　　要：现阶段,我国公路桥梁工程的施工难度越来越大,如何降低施工难度、施工成本是我国建筑工程企业急需解决的问题。挂篮施工技术以其独有的设备投入少、技术含量高、预应力和弯矩分布合理的优势在桥梁工程悬臂施工中广泛应用。结合重庆三环高速长合路龙溪嘉陵江特大桥9^(#)墩挂篮施工现场情况,论文主要总结了挂篮拼装的工艺流程、安装施工过程中的注意事项和管控要点等,可为类似工程项目提供参考。At the present,the construction difficulty of highway and bridge engineering in China is becoming more and more difficult.How to reduce the construction difficulty and construction cost is an urgent problem to be solved by China's construction engineering enterprises.Basket construction technology is widely used in cantilever construction of bridge engineering because of its unique advantages such as less equipment input,high technical content and reasonable distribution of prestress and bending moment.Combining with the construction site of hanging basket on No.9 pier of Longxi Jialing river bridge on Changhe road of the third ring highway in Chongqing,this paper mainly summarizes the technological process of hanging basket assembly,matters for attention during installation and construction and key points of control,etc.,which can provide reference for similar projects.
