Construction method of reconstruction, extension and widening bridge joint connecting structure without interrupting traffic
The invention relates to a construction method for a joint connection structure of a reorganization and extension widening bridge without interrupting traffic, the reorganization and extension widening bridge comprises a new reorganization and extension widening bridge and an existing reorganization and extension bridge which are arranged in parallel, and a splicing belt exists between the new reorganization and extension widening bridge and the existing reorganization and extension bridge. The construction method comprises the following steps: (a) arranging reorganization and extension widening bridge joint steel bars; (b) ultra-high performance concrete temporary joint connecting structures are poured in the splicing belts in the longitudinal direction of the bridge at intervals; and (c) after the ultra-high performance concrete reaches the specified strength, common concrete is used for pouring the remaining joints to form a common concrete joint connection structure, and after the common concrete in the common concrete joint connection structure reaches the specified strength, construction is finished. Compared with the prior art, the ultra-high-performance concrete temporary joint structure is utilized, so that the cooperative deformation between the reconstructed and extended widened bridges is ensured, the disturbance on the joint concrete of the reconstructed and extended widened bridges is reduced, and the construction quality of the joint structure of the widened bridges is improved.
本发明涉及一种不中断交通的改扩建拼宽桥梁接缝连接构造施工方法，改扩建拼宽桥梁包括平行设置的改扩建拼宽新桥和改扩建既有桥梁，改扩建拼宽新桥和改扩建既有桥梁之间存在有拼接带，施工方法为：(a)布置改扩建拼宽桥梁接缝钢筋；(b)在拼接带中沿桥梁纵向间隔浇筑超高性能混凝土临时接缝连接构造；(c)待超高性能混凝土达到规定强度后，利用普通混凝土浇筑剩余接缝形成普通混凝土接缝连接构造，待普通混凝土接缝连接构造中的普通混凝土达到规定强度后，施工结束。与现有技术相比，本发明利用超高性能混凝土临时接缝构造保证了改扩建拼宽桥梁间的协同变形，减少了对改扩建拼宽桥梁接缝混凝土的扰动，提高了拼宽桥梁接缝构造的施工质量。
