一种新型基桩完整性检测方法——管波法的应用介绍

A new method for testing integrity of foundation pile——Application of tube wave testing method

本文介绍一种新型的基桩完整性检测方法 -管波法,该方法利用管桩中心孔或灌注桩钻芯孔作为测试孔,在孔内注入清水,激发并接收管波,可较全面准确地对管桩和混凝土灌注桩的缺陷类型、严重程度,桩身完整性作出评判,较好地克服了传统桩身完整性检测方法的缺点。

This paper introduces a new method of pile integrity testing-tube wave testing method. The method uses the core hole of the pipe pile or the core drilling hole in the cast-in-situ pile as the test hole, fill clean water into the hole, motivate and receive tube wave, It can be more comprehensive and accurate to judge the types, the severity and the integrity of the pipe pile and concrete cast-in-situ pile, this method overcomes the shortcomings of the traditional pile integrity detection method.
