大直径厚壁钢管混凝土超声检测方法研究

Research on ultrasonic testing method for large diameter thick-walled steel tube concrete

介绍了钢管混凝土管内混凝土灌注质量的一般检测方法,并在考虑大直径厚壁钢管混凝土基础上对检测方法进行了改进,通过工程实例验证了改进后超声检测法检测钢管混凝土管内混凝土灌注质量的可行性。

This paper introduces the general detection method of concrete infusion quality in concrete-filled steel tube, and improves the detection method on the basis of large-diameter thick-walled steel tube concrete. The improved example of ultrasonic testing is used to test the concrete inside the concrete-filled steel tube. The feasibility of the improved ultrasonic testing method to detect the concrete pouring quality in the concrete-filled steel tube is verified by an engineering example.
