摘　　要：随着城市建设的不断发展,深基坑项目在城市中的建设日益增多。深基坑在建设过程中需要进行桩基围护,以确保施工安全和工程质量。而深基坑桩基围护施工技术的控制要点是保障施工过程中的关键环节,是确保工程顺利进行的重要保障。论文以具体工程项目为例,阐述了钻孔灌注桩、旋喷止水桩等关键技术,并从桩基垂直度控制、成孔质量控制、钢筋笼质量控制、防止孔壁坍塌和旋喷桩质量控制等方面总结了施工技术控制要点,旨在提高深基坑桩基围护施工的质量和安全性,降低施工风险和成本,促进深基坑工程的顺利开展,为相关人员提供参考。With the continuous development of urban construction,the construction of deep foundation pit projects in the city is increasing day by day.In the construction process of deep foundation pit,pile foundation enclosure is needed to ensure construction safety and project quality.The key control points of deep foundation pit pile foundation enclosure construction technology are to ensure the key link in the construction process and an important guarantee for the smooth progress of the project. The paper takes specific engineering projects as examples to elaborate on key technologies such as bored pile and rotary jet grouting water stop pile.It summarizes the key points of construction technology control from the aspects of pile foundation verticality control,hole quality control,steel cage quality control,prevention of hole wall collapse,and rotary jet grouting pile quality control.The aim is to improve the quality and safety of deep foundation pit pile foundation enclosure construction,reduce construction risks and costs,promote the smooth development of deep foundation pit engineering,and provide reference for relevant personnel.
