全套管旋挖扩底桩技术在某工程中的应用

Application of full casing rotary digging and expanding bottom pile in a project

结合某桩基工程案例,介绍了一种自有知识产权的新型的桩基技术——全套管旋挖扩底桩。文章详细描述其施工工艺流程、质量问题分析及控制要点,并通过桩基检测论证了方案的可行性。工程实践证明,该桩基技术节能降耗,又无噪音污染、环保、快速、安全。

The Article describe the whole casing spin dig expanded bore pile construction process,analysis in the problem of quality,and control points,which combined with the example of a pile foundation engineering in Sanming City. It demonstrates the feasibility of the scheme by the inspection of the pile foundation.
