预制梁架设施工技术探讨

Discussion on Construction Technology of Precast Beam Erection

文章以广州市从化至黄埔高速公路项目SG04合同段为例,通过深入分析预制梁架设施工过程中的关键技术,结合项目实际重难点,进一步规范施工准备、支座安装、运梁、架梁等施工。重点探讨架桥机架梁施工技术、汽车吊架梁施工技术及相关注意事项,旨在确保桥梁预制梁架设的安全,同时缩减施工工期、提高施工质量,为类似工程提供参考。

This paper takes the SG04 contract section of Conghua-Huangpu Expressway project in Guangzhou as an example.Through in-depth analysis of the key technologies in the construction process of precast beam erection,combined with the actual key and difficult points of the project,the construction preparation,bearing installation,beam transportation and beam erection are further standardized.It focuses on the beam erection construction technology of bridge erecting machine,the beam erection construction technology of automobile hoisting and related precautions,aiming at ensuring the safety of bridge precast beam erection,reducing the construction period,and improving the construction quality,so as to provide reference for similar engineering.
