海洋特殊环境桥梁钻孔桩漏浆处理研究

Research on the Treatment Measures of Bridge Bored Pile Slurry Leakage Under Special Marine Environment

依托新建福州至平潭铁路平潭海峡公铁两用大桥桩基施工,详细地介绍了桩基在钻进过程中漏浆破坏机理分析,并针对不同的漏浆原因采用不同的漏浆处理措施,以及对独立漏浆处理施工工艺进行了总结。可为以后类似环境下钻孔桩漏浆处理提供良好的借鉴。

Based on the pile foundation construction of Pingtan Strait Road-rail Bridge on newly-built Fuzhou-Pingtan Railway,this paper described in detail of the slurry leakage damage mechanism during the process of pile foundation drilling,adopted different slurry treatment measures against different reasons of slurry leakage,and summarized the construction technology of independent grouting treatment. The treatment measures of the paper are good reference for the solution to drilling pile slurry leakage in future similar environment.
