Construction method for side span cast-in-place section and closure section of continuous rigid frame bridge
The invention provides a construction method for the side span cast-in-place section and the closure section of a continuous rigid frame bridge, relates to the technical field of bridge construction, and can solve the problems of pier body deviation and bridge service life prolonging. The cast-in-place section construction method comprises the steps that a bracket stress system is constructed on one side of a transition pier; a sand bucket unloading device is mounted on the surface of the bracket stress system; a first supporting system is installed on the surface of the sand bucket unloading device, and a second supporting system is installed on the upper surface of a cover beam; a side span cast-in-place section formwork system is installed through the first supporting system and the second supporting system; and side span cast-in-place section concrete is poured based on the side span cast-in-place section formwork system. According to the side span closure section construction method, the closure section suspension system and the closure section stiff framework are added while the bracket stress system is utilized, so that the closure section formwork system is supported, and closure section concrete is poured. Through the bracket stress system and the cover beam supporting formwork system, the number of temporary supporting materials for side span cast-in-place section construction is reduced, and various pre-burying influencing the durability of the pier body does not need to be conducted on the pier body.
本公开提供了一种连续刚构桥边跨现浇段及合拢段施工方法，涉及桥梁施工技术领域，能够解决墩身偏位和延长桥梁寿命的问题。现浇段施工方法包括：在过渡墩一侧施工托架受力体系；在托架受力体系表面安装卸载砂桶装置；在卸载砂桶装置表面安装第一支撑系统，在盖梁上表面安装第二支撑系统；利用第一、二支撑系统安装边跨现浇段模板系统；基于边跨现浇段模板系统浇筑边跨现浇段混凝土。边跨合拢段施工方法是利用托架受力体系的同时增加合拢段悬吊系统和合拢段劲性骨架，使其支撑合拢段模板系统并浇筑合拢段混凝土。本公开通过托架受力体系和盖梁支撑模板系统，缩减了边跨现浇段施工临时支撑材料数量，并且无需对墩身进行各种影响其耐久性的预埋。
