摘要

为了探索超声波对波纹管注浆密实性与空洞部位的检测能力,先采用弹性波对注浆波纹管及混凝土(即避开波纹管)进行检测,通过数据对比分析,判断出存在缺陷的波纹管;再采用超声波对存在缺陷的波纹管进行检测,对检测数据进行分析研究,判断缺陷在波纹管中的具体位置及大小。试验梁的验证结果表明,用该方法判断出的空洞位置及大小与实际设缺情况基本一致,因此用该方法检测预应力波纹管注浆密实性与空洞部位是可行的,从而为波纹管注浆检测提供了理论指导。
A method to explore detecting function for grouted density and empty hole of corrugated pipe is proposed in the paper.Firstly,the grouted corrugated pipes and concrete(avoiding corrugated pipes) were detected by using elastic wave to judge defective corrugated pipes through comparative analysis of the data.Secondly,the defective corrugated pipes were detected using ultrasonic wave to determine the specific location and size of defect in corrugated pipes by the analysis of the test data.Finally,the above-mentioned results were verified by actual experiment.The result shows that judged location and size of the empty hole are consistent with the actual situation.So it is feasible to detect grouted density and empty hole of pre-stressed corrugated pipe with the method.The presented method provides theoretical guidance for grouted detection of corrugated pipe.
