摘要
结合单壁螺纹塑料套管现浇混凝土桩—PTCC桩在岳常高速公路软基处理试验段和其他高速公路中的应用,对其桩的组成、施工工艺、成桩质量控制以及检测方法等进行了研究,探讨了应用效果和经济性。结果表明,PTCC桩是一种质量容易控制、施工速度快、经济性好、检测方便的地基处理新方法。
Combined with the application of single wall threaded plastic tube cast-in-place concrete pile(PTCC Pile) in soft foundation test section of Yuechang Expressway and other expressways,the composition,construction technique,quality control and detection method of PTCC pile are studied to discuss its application effect and economical efficiency.The result shows that PTCC pile is a mew method for foundation treatment with easy quality control,rapid construction speed,high economical efficiency and convenient detection.
