Construction technology of continuous beam crossing high-speed extra-large bridge
The invention relates to the technical field of continuous beam construction, in particular to a construction technology of a continuous beam crossing a high-speed extra-large bridge. The method comprises the following steps: 1, constructing a lower structure; 2, mounting a support; thirdly, temporary consolidation is conducted; 4, constructing a No.0 block; 5, cantilever section construction; 6, side span cast-in-place section construction; 7, constructing a closure section; and 8, constructing a bridge deck system and embedded parts. Concrete of all sections of the continuous beam is formed through one-time pouring, and the principle of balanced and symmetrical construction is mastered in box beam cantilever pouring. According to the structural characteristics and design requirements of the box girder and in combination with similar bridge box girder construction experience, a mature rhombic hanging basket is planned to be adopted for box girder cantilever pouring construction, road closing construction is not needed, the construction period of a continuous beam is short, and safety is high.
本发明涉及连续梁施工技术领域，具体为一种跨高速特大桥连续梁的施工工艺。步骤包括：一、下部结构施工；二、支座安装；三、临时固结；四、0号块施工；五、悬臂段施工；六、边跨现浇段施工；七、合龙段施工；八、桥面系及预埋件施工。本发明本连续梁各节段混凝土一次浇筑成型，箱梁悬臂浇筑掌握平衡对称施工的原则。根据箱梁结构特点和设计要求，并结合同类桥梁箱梁施工经验，拟采用成熟的菱形挂篮进行箱梁悬臂浇筑施工，无需封闭道路施工，连续梁施工周期短，安全性高。
