摘要
海华大桥主梁悬浇采用前支点牵索挂篮施工,受挂篮自重大,桥位区施工场地有限,以及工期紧任务重等现状影响,海华大桥挂篮拼装采用地面拼装,横向滑移,对称平衡提升等工艺,顺利完成挂篮安装并投入使用,并对前支点挂篮安装关键技术的总结与阐述,详细介绍安装过程的具体工艺流程及相关临时结构设计。
Suspension of the main beam of Haihua Bridge adopts the front support pull rope hanging basket construction. Due to the fact that the hanging basket is self-important, the construction site in the bridge location area is limited, and the time limit of the construction period is heavy, the Haihua Bridge hanging basket assembly is ground assembled. Lateral slip, symmetrical balance and other processes, the successful completion of the hanging basket installation and put into use, and summary and explanation of the key technologies for the front pivot point hanging basket installation, detailed introduction of the specific process flow of the installation process and related temporary structure design.
