摘要
超深水泥土搅拌桩施工工法作为一项新的土体加固工艺技术,与其它施工方法相比,具有施工时间短、占地面积小、施工噪音低、震动小、加固深度可达60 m、对周围地下结构和地基的挤压作用小等特点。本文介绍和分析了超深水泥搅拌桩的施工难点、质量控制措施、关键施工技术,以及在轨道交通工程中的应用。
The construction method of super-deep cement-soil mixing pile is a new soil consolidation technique.Compared with the other construction methods,the super-deep cement-soil mixing pile method has the following advantages: to shorten construction time,reduce land occupation,lower noise,reduce vibration,deepen the consolidation depth to 60m,and reduce squeezing effect on surrounding underground structure and foundation.The super-deep cement-soil mixing pile method is introduced and analyzed from the aspects of construction difficulties,quality control measures,key construction techniques,and its application in rail transit projects.
