| 摘 要： | 介绍了现浇混凝土薄壁管桩（PCC桩）成桩工艺。结合PCC桩在盐通高速公路软基处理中的应用，在现场对PCC桩施工工艺进行了试验研究，探讨了混凝土坍落度、拔管速度、施打顺序对PCC桩质量的影响，并对其充盈系数进行了分析研究。同时还对PCC桩质量检测方法进行了研究，并对可能出现的质量问题及预防措施做了初步探讨，可供相关工程参考

| Abstract: | The construction techniques of cast-in-situ concrete thin-wall pipe pile(referred to PCC pile) is introduced and tested based on the application of PCC pile in the soil improvement of Yan-Tong expressway, Jiangsu Province. The collapse degree of concrete, velocity of pile extraction, sequence of pile installation and fullness coefficient of concrete of PCC pile during construction are studied in detail. On the other hand, the methods of PCC pile quality detection are discussed; and the possible problems during construction and countermeasures are discussed too. |
