摘要
根据螺旋锥体挤土桩的施工方法以及钻头专利,结合该工法施工的多项工程案例,给出了螺旋锥体挤土压灌桩施工的条件,并分析了该施工工法的优势与特点;设计了螺旋锥体挤土压灌桩施工工艺流程图,并针对施工中出现的质量通病,提出了7项施工质量控制关键点,同时结合工程检测,提出了螺旋锥体挤土压灌桩的加强质量技术措施。经施工验证,各项工程均满足标准要求,为类似工程施工提供借鉴。
According to the patent of the construction method of the spiral cone squeezing pile and the patent of the drill, the construction conditions of the soil filling pile with spiral cone construction are given, and the advantages of the construction method of the soil filling pile with spiral cone are given, and the spiral cone extrusion is designed. The construction process flow chart of earth pressure grouting pile, and aiming at the common quality defects in construction, 7 key points of construction quality control are put forward. At the same time, combined with the engineering test, the strengthening quality technical measures of soil filling pile with spiral cone are put forward. Through engineering tests, all projects meet the standard requirements, which can provide an effective reference for similar projects.
