客运专线长螺旋钻机施工CFG工艺及质量控制

Construction Technology and Quality Control of CFG Pile by Long Spiral Drilling Machine for Railway Passenger Dedicated Line

研究目的:CFG桩复合地基作为软土地基加固的一种措施,在高速铁路客运专线上应用时间较短,缺乏相关工程经验。因此,有必要对其工艺进行分析总结,以指导施工。研究结果:结合武广铁路客运专线CFG桩复合地基施工实践,总结出长螺旋钻机施工CFG桩的工艺及质量控制要点,阐述了常见问题的原因和解决措施。

Research purposes:Soft soil reinforcement as a measure of CFG pile composite foundation is seldom used in high-speed passenger rail line.So it is lack of relevant work experience.Therefore,it is necessary to sum up the construction process in order to guide future construction. Research results:Based on the CFG composite foundation construction practice for Wuhan-Guangzhou railway passenger dedicated line,this paper summarizes construction technology and quality control points of CFG pile using long spiral ...
