摘要
泥浆护壁钻孔灌注桩有一定的缺陷,桩底注浆技术有效地补充了这些缺陷,并能大幅度提高承载力。本文通过工程实例阐述了桩底注浆的工作原理和工艺流程,指出了桩底注浆技术的发展前景。
The technology of grouting after pile driving at the bottom of pile makes up for defects caused by the bore cast-in-place pile protecting bore wall with mud and thereby it enhances the bearing capacity of pile greatly. Here the function mechanism and the technology process of grouting after pile driving technology are explained by engi-neering examples and the development prospect is pointed out.
