This paper discusses the application of high-pressure jet grouting pile in deep foundation pit excavation and support around the original natural foundation. Through the analysis of background and problems, this paper puts forward concrete solutions such as construction technology, parameter selection and on-site monitoring of high-pressure jet grouting pile. At the same time, combined with practical engineering cases, the successful application of this scheme is analyzed. The research shows that high-pressure jet grouting pile is an effective supporting scheme for deep foundation pit excavation, with high safety and reliability. It has a wide application prospect in deep foundation pit excavation and support scheme, which can effectively improve the bearing capacity and stability of soil, prevent soil displacement and collapse, and play a waterproof role; At the same time, it is convenient to operate and has low requirements for equipment, which can shorten the construction period and reduce the construction cost. Has a significant advantage. In practical engineering, the appropriate parameters and construction technology of high-pressure jet grouting pile should be selected according to the specific situation to obtain the best supporting effect.
