钻孔灌注桩桩底后注浆技术及其应用
摘要:泥浆护壁钻孔灌注桩有一定的缺陷,桩底后注浆技术有效地弥补了这些缺陷,并能大幅度提高承载力。通过工程实例阐述了后注浆工艺的作用机理及工艺流程,指出了后注浆技术的发展前景。
Abstract:The technology of grouting after pile driving at the bottom of pile makes up for some inherent 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 technological process of grouting after pile driving technology are explained by engineering examples and the development prospect is pointed out.
