Scope: This document specifies the detection equipment, preparation for detection, detection, data analysis and judgment, and detection reports for detecting internal defects in cement concrete using array ultrasonic methods. This document is applicable to the detection of internal defects in cement concrete structures using array ultrasonic methods in the fields of highway and water transport engineering. Main technical content: The main technical content of the technical specification for detecting internal defects in cement concrete using array ultrasonic methods is as follows: Ultrasonic nondestructive testing is an important technical means for diagnosing the health status of cement concrete structures. By transmitting and receiving ultrasonic waves, we can obtain the wave propagation information inside the concrete, and then use mathematical models to invert it into a corresponding physical value matrix, which is finally transformed into a structural image of the concrete. This method can achieve intuitive judgment and quantitative analysis of internal defects in concrete, and completely avoid the damage to the concrete caused by detection operations. This document specifies the terms and definitions, general provisions, preparation for detection, detection, and detection reports for detecting internal defects in concrete using array ultrasonic methods, which is of great significance for improving the standardization and normalization of the application of array ultrasonic methods in highway engineering.
