公路桥梁建设中钻孔灌注桩质量控制方法探讨

结合实践对在钻孔灌注桩在整个施工过程中出现的坍孔、卡管、掉物等故障提出了回填重钻、淤泥吸拔、叉钩打捞等现场实用解决方法,为公路桥梁中钻孔灌注桩的施工安全以及质量控制具有一定的指导意义。

Discussion on Quality Control Method of Bored Piles in Highway Bridge Construction

Quality control method of bored piles is analyzed in detail,through the observation and summery of real-time con- struction management.Moreover,aiming at the fact that bored piles may have collapse hole,the card,and other errors throughout the process of construction,the settlements such as fault swap of proposed backfilling heavy drilling,mud suction stubs,fork hook salvage,and other practical settlements are proposed.These methods for the safety and quality control of bored piles in the construction of highway bridge offer some guidance.
