摘　　要：人工挖孔灌注桩是桩基础的一种常见形式 ,它具有施工工艺简单、成孔机具少、工程质量可靠、施工进度快、成本低的优点。适用于地质条件好、无地下水或地下水量很少的密实土或岩石地层 ,特别是桩基数量不多 ,搬迁钻孔设备困难的条件下使用具有明显的经济效益。本文根据工程实践 ,介绍了在红粘土与中、微风化泥岩条件下人工挖孔灌注成孔方法、灌注混凝土等施工工艺 。The one strain ordinary saw form of the labour dug hole perfusion stake yes stake foundation,either be it possess c onstruction craft simplicity,become hole engine tool fewness,engineering quality credibility,construction tempi quick to,cost low merit.Apply to terra nature co ndition best,without groundwater or groundwater measure tiny spissitude solid ea rth or rock strata up,it is stake radices measure not much up to in particular,m ove move drill equipment difficult condition down use possess overt economy bene fit.Text as per engineering practice,introduce know clearly under conditions of red clay and suffer,breeze melt mud rock labour dug hole perfusion become hole m eans,perfusion concrete grade construction craft,versus hole within demolish too proceed know clearly introduce.
