青龙小桥桩孔施工故障处理的几个案例

Several cases of fault treatment in pile-hole construction of Qinglong small bridge

结合永福—雁山二级公路青龙小桥桩基工程实例,对桩基成孔过程中出现的斜孔、掉钻、埋钻、坍孔四种故障进行了原因分析,并分别阐述了相应的处理方法,以解决故障,从而保证施工进度和工程质量。

Combining with pile-hole project of Qinglong small bridge on secondary road from Yongfu to Yanshan, the paper analysis causes of four kinds of faults in the pore-forming process of pile foundation, that is inclined hole, losing drill, burying drill and hole collapse, describes corresponding treatment method respectively, so as to solve fault, thus ensuring construction procedures and project quality.
