Application of Ultrasonic Nondestructive Testing Technology to the Horizontal Joint Slurry at the Bottom of Shear Wall

Ultrasonic nondestructive testing (NDT) technology has a wide range of applications in the connection nodes of prefabricated building components. It is mainly used to test the quality of the connection nodes of prefabricated building components, such as filling degree, anchorage of steel bars, etc. This paper mainly introduces the detection of the filling degree of the shear wall bottom joint slurry. By discriminating acoustic parameters such as “sound velocity, amplitude, waveform” in ultrasonic detection method, the fullness of grouting is detected. According to the examples, the operation steps such as field detection, data processing and analysis and entity excavation verification are summarized, and suggestions are provided for the efficient application of ultrasonic detection technology in the quality detection of fullness.
