Method for replacing vertical support of steel box girder bridge
The invention discloses a method for replacing a vertical support of a steel box girder bridge. The method comprises the following steps that firstly, construction preparation is conducted; secondly, a jack is installed at the top of the pier, temporary supports are installed on the two sides of the jack, and a distribution beam is installed above the temporary supports; thirdly, the jack is connected with a synchronous jacking system; 4, arranging a real-time monitoring system; 5, top testing, wherein top testing loading is conducted after the jacking device is accepted and accepted to be qualified; sixthly, overall jacking is conducted, and all the jacks conduct jacking slowly in a grading mode; seventhly, an original support is dismantled; and eighthly, a new support is installed. The structure of an original structure is not changed, construction is convenient and fast, traffic influence is small, adaptability is high, and the method has the remarkable advantages of being convenient, fast, green and economical.
本发明公开了一种钢箱梁桥竖向支座更换方法，包括以下步骤：步骤一、施工准备；步骤二、在墩顶位置安设千斤顶，在千斤顶的两侧安装临时支撑，在临时支撑上方安装分配梁；步骤三、将千斤顶连接同步顶升系统；步骤四、布设实时监测系统；步骤五、试顶，顶升装置验收合格后进行试顶加载；步骤六、整体顶升，所有千斤顶缓慢分级顶升；步骤七、拆除原支座；步骤八、安装新支座。本发明不改变原有结构的构造，施工便捷快速、交通影响小、适应性强，具有方便、快捷、绿色、经济的显著特征。
