接触式钻孔灌注桩成孔质量检测系统的应用

The Application of Testing System for Contact-type Bored Pile Quality

结合当前钻孔灌注桩成孔检测方法的不足,分析了接触式成孔检测系统的优点并对其测量原理和方法包括孔深、孔径、沉渣厚度、孔斜等问题均进行了介绍。并以天津某大楼钻孔灌注桩成孔工艺为例,阐明该方法在保证成桩质量上具有重要的意义。

In connection with the bored pile lacking of quality testing methods,the advantages of contact-type hole testing system as well as its principle and method of measurement,including hole depth,diameter,thickness of sediment,oblique are introduced in this paper.Finally,taking the hole forming process in some building in Tianjin for example,it is shown that this testing system is of great significance in quality assurance of bored pile.
