摘　　要：套管成孔灌注桩适应较复杂地层，能用小桩管打较大截面桩，承载力大；有套管护壁，可避免坍孔、瓶颈、断拉、移位、脱空等缺陷，质量可靠；能沉能拔，施工速度快，效率高，操作简便安全。文章以广州市番禺区东涌镇细沥泵站桩基工程为例，介绍了套管成孔灌注桩应用于淤泥地基施工的技术措施，工程实践证明，套管成孔灌注桩施工工艺在广东沿海淤泥地基中是完全可行的。Adapt to more complex formation of the casing into the hole pile, with a small pile pipe to play a larger cross - section pile bearing capacity; casing wall protection, to avoid hole collapse, bottlenecks, and off pull, shift off waited in vain for defects quality; It can fall and pull, with high construction speed, high efficiency, easy and safe. The article taking pumping station pile foundation engineering in Dongyong Town, Panyu District, Guangzhou City as an example, introduces the casing into a hole pile of technical measures applied to silt foundation construction. Engineering practice shows that the casing into the hole pile construction technology in Guangdong coastal mud foundation is entirely feasible.
