摘要
对水泥搅拌桩技术的工艺和质量控制要点进行了概述,并用工程实例介绍了水泥搅拌桩技术在河道治理工程中的应用和效果。分析结果表明,水泥搅拌桩能够有效地提高软土地基土层的物理力学指标,同时增加水泥含量和添加减水剂有利于提高水泥搅拌桩的成桩质量,可为类似水利工程的建设提供参考。
The process and quality control points of cement mixing pile technology were summarized,and application and effect of cement mixing pile technology in river regulation engineering were introduced in detail with engineering examples. The analysis results showed that the cement mixing pile could effectively improve the physical and mechanical indexes of soft soil foundation. At the same time,increasing the cement content and adding water reducer were conducive to improving the pile quality of cement mixing pile,which could provide reference for the construction of similar water conservancy projects.
