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。 In this paper, we introduce a new method to detect the integrity of pile foundation-tube wave method, which uses the center hole of the pipe pile or the core hole of the bored pile as the test hole, injecting clear water into the hole to excite and receive the pipe wave, Judging the defect type, severity and pile integrity of pipe pile and concrete bored pile, the defects of the traditional pile integrity testing method are well overcome.
