Hanging basket suspension casting construction method for bridge engineering prestressed box girder
The invention discloses a hanging basket suspended casting construction method for a bridge engineering prestressed box girder, which comprises the following steps: mounting a hanging basket in place, and splicing by adopting a reverse construction method, namely transporting all components of the hanging basket to a construction site, cleaning and detecting a mounting position, and mounting a rail; the hanging basket needs to be anchored and hung on a constructed beam section in the working process to become an aerial platform for construction operation of the next section, and after construction of one section of the bridge is completed, the next section of the bridge can be constructed by moving and fixing the hanging basket; and in the hanging basket walking operation, the hanging basket walks in the mode that the track beam is jacked firstly and then the main truss is jacked. The technical problems of linear control, multiple system conversion and the like in hanging basket cantilever casting construction can be solved.
本发明公开了一种桥梁工程预应力箱梁的挂篮悬浇施工方法，包括如下步骤：挂篮安装就位，采用逆作法进行拼装，包括将挂篮所有构件运到施工现场，并清理和检测安装位置，轨道安装；挂篮悬浇操作：工作中挂篮需锚固悬挂在已施工梁段上，成为下一节段施工作业的空中平台，待桥梁的一个节段施工完成后通过移动并固定挂篮即可进行下一节段施工；挂篮行走操作，采取先顶进轨道梁，后顶进主桁架的方式进行挂篮行走。本发明可以解决挂篮悬臂浇筑施工中线型控制、体系多次转换等技术难题。
