With the rapid development of the social economy,China's inland waterway transportation industry has achieved remarkable results.The application of drilled pile can maintain the stability of engineering structures.Ultrasonic transmission testing technology is a widely used non-destructive testing method.When ultrasonic pulses pass through the pile,their propagation speed,attenuation,and reflection can reveal the quality,uniformity,and integrity of the concrete.This detection method can not only test the discontinuity inside the concrete,but also evaluate the integrity of the pile body.Therefore,based on a comprehensive understanding of the principle of ultrasonic transmission method detection,this article analyzes the key points of its detection technology,and combines specific cases to detect the integrity of drilled pile through ultrasonic transmission method,in order to ensure the safety and quality of the project.
