摘　　要：深井灌注技术早期主要用于处置油气生产产生的废弃物,由于其自身特点及工艺日益成熟,现广泛应用于大直径深基础工程的施工。结合工程实例,介绍了深井灌注桩施工的工艺流程,分析了质量安全控制的要点,以期对深井灌注桩在复杂地质情况下大直径深基础施工中的应用起到一定的参考价值。Cast-in-place concrete pile by using deep well injection method was originated in the U.S.The injection method was used for the treatment of wasted materials from the petroleum generation process by injecting the waste material into the deep rock fissures through the deep wells.Currently,this injection method has been widely used in the deep and large diameter castin-place reinforced concrete pile installations.This paper presents a case history of the technique and quality control aspects of constructing of the large diameter cast-in-place reinforced concrete piles.
