沉管桩的质量问题

On the Problem about Quality of Pipe Setment Concreted Pile

在各种灌注成桩工艺中，沉管灌注桩的问题最为突出，也很难处理，有些是由于设计时参数的选用及桩型不当，更多的是工艺、机具、检测手段、施工管理等方面的问题。本文就此分析了产生问题的原因。

Of all different techniques for concreting piles, the problem on pipe setment concreting piles is a dead outstanding and very difficult to be handled. Some of the problems happen due to improper timing parameter selection and pile′s shape unsuitable, still more due to technique, working tools, surveying measurement and constructural management. This paper presents the cause and reason for the happening problems, and proposes solutions.
