摘　　要：干孔钻进无水法灌注混凝土施工工艺,采用旋挖钻钻孔,清孔后无水法灌注混凝土,无须泥浆护壁,且成桩质量可靠、可大幅度节约工期和工程成本,值得加以推广和应用。Rotary drill is adopted for drilling in dry hole drilling non-aqueous technique pouring concrete construction technology. Non-aqt,eous technique is adopted for pouring concrete after hole cleaning. Wall protection bv slurry is not needed. In addition, buih-up piles have reliable quality, eonstnlction duration and engineering cost can be greatly saved. The technology is worth popularization and application.
