浅析复杂覆盖层钻探工艺技术及应用

Simple Analysis on Drilling Techniques in the Complicated Overlying Strata and its Application

在岩土工程地质勘察中,复杂覆盖层给钻探施工带来极大的工艺技术处理难题,严重影响钻探施工安全、工程质量与技术经济效益,增加施工劳动强度,改善该类地层的工程钻探施工工艺技术成为工程地质勘察工作中的突出难题,就此总结一些施工经验供同行参考。

In geological investigation of geotechnical engineering, the compllcateo overlying strata bring huge difficulties in drilling construction ,which affects seriously the safety of drilling construction, engineering quality and technical economic benefit, moreover,increases labor intensity in the construction. Therefore, it becomes a significant difficulty in engineering geological investigation that how to improve the drilling techniques in such strata. In the paper, some construction experiences are summed up for the reference.
