CDJ-1检测仪在钻孔扩底灌注桩施工中的应用

Application of CDJ-1 Detector in Safe Construction of Drilling Bottom-enlarged Grouting Piles

钻孔扩底灌注桩对施工要求比较高,特别是成孔质量的好坏直接关系到该桩型优势的发挥。介绍了CDJ-1检测仪的工作原理,在一典型工程中使用该仪器对桩孔进行了检测,并对检测数据进行了统计和初步分析,结果表明该工程中所检测的桩孔全部合格,CDJ-1检测仪保证了钻孔扩底灌注桩成孔作业过程中的安全施工。

The construction requests for drilling bottom - enlarged grouting pile are higher than other piles and especially the condition of hole completion qualtity affects the full play of its advantages directly. The operation principle of CDJ - 1 detector is introduced, pile holes are examined by this instrument in a typical project and statistics and iitial analysis on the examined data are conducted. The results show that the holes examined are all qualified in this project and CDJ - 1 detector has guaranteed the construction safety in the course of the hole completion for drilling bottom - enlarged grouting pile.
