Bridge pile foundation underpinning method
The invention discloses a bridge pile foundation underpinning method. The method comprises the steps that a pile foundation and a bearing platform are newly built outside an interval tunnel; a temporary supporting system is erected on the newly-built bearing platform; carrying out system conversion for the first time; the existing bridge piers, bearing platforms and obstacle pile foundation structures are dismantled; a post-pouring bearing platform is poured; pouring a newly-built pier; carrying out secondary system conversion; and dismantling the temporary support system. By means of the scheme, the method can better adapt to operation in narrow and small urban space and under complex conditions, the construction speed is high, and interference to the surroundings is small.
本发明公开了一种桥梁桩基托换方法，该方法包括：在区间隧道外新建桩基及承台；在所述新建承台上搭设临时支撑系统；进行第一次体系转换；拆除既有桥墩、承台、及障碍桩基础结构；浇筑后浇承台；浇筑新建桥墩；进行第二次体系转换；拆除临时支撑系统。利用本发明方案，可以更好地适应在城市狭小空间及复杂条件下作业，施工速度快、对周边干扰较小。
