试谈钻孔灌注桩施工如何保证成孔质量

Elementary Discussion on How to Guarantee Quality of Forming Hole in Construction of Cast-in-situ Pile

钻孔灌注桩的应用广泛,施工中遇上不确定因素影响较多,虽然这种施工工艺已较为平常,但做起来绝非外人眼中的千篇一律,虽然使用的是笨重的机械,但做的是精细的技术活,稍有疏忽,留下隐患则难以弥补。该文重点论述灌注水泥混凝土前的成孔质量控制。成孔的质量直接关系到成桩的质量,是钻孔灌注桩施工质量控制的关键环节之一。该文对此进行了较为全面的分析论述。

The cast-in-situ pile is widely used with more indeterminacy factors in the construction. This construction technology has been more common, but its implementation does not follow the same pattern. The machinery is heavy, but the technology is fine. The hidden danger is hard to redeem if slight negligence. The article focuses discussion on the quality control of forming hole before the cement concrete is grouted. The quality of forming hole is directly related to the quality of the finished pile, and is one of the key links in the quality control of the cast-in-situ pile construction. The article more completely analyzes and discusses the quality control.
