摘要
以天津某地铁深基坑地下连续墙接缝止水加固工程为例,对目前双高压旋喷桩的施工工艺进行总结分析,提出了在含承压水粉土、粉砂层三重管双高压旋喷桩施工参数和管控要点,并在工程实践中进行运用,经实践检验,成桩质量较好,达到了止水加固的目的.
Taking a deep pit in the subway underground continuous wall joint sealing reinforcement project in Tianjin as an example. The construction process of the double High - Pressure Rotary Jet Pile are summarized. Some construction parameters and control points of triple double High -Pressure Rotary Jet Pile in the pressure silt and sandy silt layers are raised. It is used in engineering practice, which gets a better quality of pile and achieves the purpose of sealing reinforcement after the practice tests.
