三轴水泥土搅拌桩施工质量控制

Construction Quality Control of Triaxial Cement Soil Mixing Pile

三轴水泥土搅拌桩因其较好的止水效果作为基坑围护结构已经得到广泛应用,但目前工程上普遍存在桩体垂直度及桩身强度达不到设计及规范要求的问题,这也直接给基坑开挖带来了安全隐患。结合台州现代大道项目三轴水泥土搅拌桩施工,采用施工工艺的调整及三轴搅拌桩施工参数监测仪的引进等措施有效地解决了桩体垂直度及桩身强度达不到要求的问题,并带来了一定的经济效益及社会效益。通过总结,可为同类型工程提供借鉴与思路。

The triaxial cement soil mixing pile has been widely used as foundation pit support structure because of its better water stop effect,however,there is a common problem in the engineering that verticality of pile body and the strength of pile body cannot meet the design and specification requirements,this also directly brings hidden to excavation.Combined with the triaxial cement soil mi xing pile construction of Taizhou modern avenue project,the adopting of the adjustment of construction technology and the introduction of triaxial cement soil mixing pile construction parameter monitor can effectively solve the problems of the pile body verticality and pile body strength failing to meet the requirements,and brought a certain degree of economic and social benefits.Through the summary,it can provide reference and idea for the same type of project.
