摘要
为解决旋挖成孔灌注桩在砂层、淤泥等特殊地层中经常存在的垂直度不达标、塌孔、扩孔、孔底沉渣不达标等几个主要质量问题。通过工程实例,分析工程特点,总结了相应的技术措施,以供类似工程施工提供参考。
In order to solve the main quality problems of rotary bored cast-in-place pile in special strata such as sand layer and silt,such as substandard perpendicularity,hole collapse,hole expansion,substandard sediment at the bottom of the hole and so on.Through engineering examples,this paper analyzes the engineering characteristics and summarizes the corresponding technical measures,so as to provide reference for the construction of similar projects.
