Construction method for improving and transforming anti-seismic performance of multi-linkage beam bridge
The invention belongs to the technical field of bridge construction, and particularly relates to a construction method for improving and transforming the anti-seismic property of a multi-linkage beam bridge. Comprising the following steps that A, fixing steel rings are symmetrically installed between a second header beam bottom plate and a first transition pier and between the second header beam bottom plate and a second transition pier respectively; b, fixing steel rings are installed between the first header beam bottom plate and the first transition pier and between the third header beam bottom plate and the second transition pier respectively; c, fixing steel rings are installed between the second header beam bottom plate and the first header beam bottom plate and between the second header beam bottom plate and the third header beam bottom plate respectively. The installation operation is simple, and the system is safe and stable; the shock absorption and isolation level of the multi-connected beam bridge is improved, and the safety risk under the earthquake load effect of the multi-connected beam bridge is prevented and solved.
本发明属于桥梁施工技术领域，具体来说，是一种多联梁桥抗震性能提升改造施工方法。包括以下步骤：A在第二联箱梁底板与第一过渡桥墩、第二过渡桥墩之间分别对称安装固定钢环；B在第一联箱梁底板与第一过渡桥墩、第三联箱梁底板与第二过渡桥墩之间分别安装固定钢环；C在第二联箱梁底板与第一联、第三联箱梁底板之间分别安装固定钢环。本发明，安装操作简单、体系安全稳定；提升多联梁桥减震隔震水平，防范化解多联梁桥地震荷载作用下安全风险。
