摘要
以山西省儿童医院综合门诊楼为例,分析了钻孔灌注桩后压浆技术提高单桩承载力的机理,介绍了其施工工艺,并阐述了注浆参数的确定方法及注浆技术,提出了后压浆的施工质量保证措施,通过对桩基检测结果的研究,证明了该方法成本低、易施工、高效率等技术优势。
Taking the comprehensive outpatient building of Shanxi Children’ s Hospital as an example, analyzed the mechanism of bored pile post grouting technology improvement the single pile bearing capacity, introduced its construction technology, and elaborated the determination method and grouting technology of grouting parameters, put forward the construction quality ensure measures of post grouting, through the research on pile foundation test results, proved that the method with the low cost, easy construction, high efficiency and other technology advantages.
