摘要 论述了钻孔灌注桩成孔施工技术,详细介绍了灌注桩成孔施工中常见的塌孔、孔径达不到设计要求扩孔及缩孔、孔位倾斜、孔底沉渣超标、孔深达不到设计要求等问题产生的原因以及预防和处理措施,以减少工程经济损失。成孔作为灌注桩施工中的关键步骤,应当引起人们的重视。 This paper discusses the construction technique of bored piles into holes hole filling pile is introduced into the construction of common hole collapse, the pore size can not meet the design requirements of bore hole, shrinkage cavity and hole inclination, grout.thus, at the bottom of the bore hole depth is less than the causes of such problems as the design requirements and the prevention and treatment measures, to reduce the engineering economic losses. Pore forming as the key step of filling pile construction, should cause the attention of people.
