风化岩层地质旋挖成孔灌注桩施工技术探析——以仁怀市2020年鲁班公租房建设项目为例

Analysis on the Construction Technology of Geological Rotary Hole-dug Cast-in-place Pile in Weathered Rock——Taking the 2020 Luban Public Housing Construction Project in Renhuai City as an example

文中以仁怀市2020年鲁班公租房建设项目为例,从测量放线、孔桩成孔、清孔、桩身混凝土施工等六方面对旋挖成孔灌注桩施工技术进行探析。通过本工程的桩基施工,为类似条件下进行旋挖成孔灌注桩施工提供参考。

Taking the construction project of Luban public rental House in Renhuai City in 2020 as an example,this paper analyzes the construction technology of rotary hole-dug cast-in-place pile from six aspects,such as measuring and setting off,hole making,hole clearing and pile concrete construction.Through the pile foundation construction of this project,it can provide reference for the construction of rotary hole grouting pileunder similarconditions.
