冲击回波法检测预制构件管道压浆密实性研究

Study for grouting density inspection of prefabricate pipe grouting by means of shock echo method

介绍了冲击回波法的基本原理及其在混凝土结构无损检测中的应用,并结合工程实例,对预制管道内密实、全空及半空的状态进行了压浆密实性检测,指出冲击回波法检测预制管道压浆密实性是一种可行的方法。

This paper introduces the basic principle of the shock echo method and its application in nondestructive testing of concrete structure,and combined with engineering examples,based on the prefabricated pipe tightly,the whole state of empty and half empty,and the grouting compactness detection,point out the shock echo method to detect precast pipe grouting compactness is a feasible method.
