海相淤泥质软土三轴搅拌桩施工应用

Key Research on Construction of Marine Silt Soft Soil Three-Axis Mixing Pile

海相软弱土层地基处理在工程中的应用越来越广泛,文章以福州地铁4号线化工路站加固工程为例,介绍了三轴搅拌桩工艺原理、施工准备、主要施工工艺流程及质量控制要求和施工注意事项,阐述了施工过程中水泥用量计算公式,并介绍了施工水泥质量控制措施,为后续类似工程提供参考。

The foundation treatment of marine soft soil is widely used in engineering.Taking the strengthening project of chemi- cal road station of Fuzhou Metro Line 4 as an example, this paper introduced the construction preparation of three-axis mixing pile,main construction process flow,quality control requirements and construction points for attention.This paper expounded the calculation formula of cement quantity in construction process, and introduced the quality control measures of construction ce- ment,which provides a reference for similar projects.
