S229线汶河辉山大桥桩基加固处理方法

摘要

通过对公路桥梁桩基的病害进行研究,提出了采用人工装砂袋配合挖掘机施工围堰,桩基外支圆柱形钢模板浇筑混凝土的方法,解决了因河床下降导致的桩基外露,从而影响桥梁安全使用的病害的问题。%Through studying the highway bridge pile foundation diseases,the paper puts forward reinforcing measures of artificially filling sandbags coordinating excavator to construct the cofferdam and cylindrical steel template established outside of pile foundation to cast concrete.As a result,it solves the problem that pile foundation exposing outside owing to river bed decreasing influences the bridge safety usage.
