? 2022 Elsevier LtdAiming at the accurate detection problem of concrete pouring thickness, a solution idea of synchronous data acquisition and concrete thickness detection technology based on ultrasonic inclined plane reflection and vertical reflection of ultrasonic full pulse signal is proposed. Taking full advantage of the acoustic response characteristics of different reflection models, three-dimensional modeling and data visualization optimization scheme are formed. By combining the different depths data and local measurement data, the characteristic parameter extraction technology of different media in the borehole is formed, which lays a foundation for solving the key problem of accurate detection of laitance layer thickness. Finally, a comprehensive technical system is formed, and the technical system is applied to practical engineering. The measurement results are basically consistent with the actual situation. The practical application results show that this technology can realize the three-dimensional imaging and quantitative characterization of the medium state in the borehole during concrete pouring.
