Abstract:In view of the lack of effective non-destructive testing technology for the grout-filled pipe splice grouting fullness of prefabricated concrete structures, a non-destructive testing method based on portable X-ray was used to test the grouting quality of single-reinforced and reinforced concentrated beam-grouted anchor-jointed nodes. The principle and method of portable X-ray technology to detect concrete structure defects were introduced. The test results of portable X-ray technology for concrete specimens with large and small diameter corrugated pipes under various working conditions were described in detail. Through the analysis of X-ray imaging, it is concluded that the portable X-ray technology can accurately determine the grouting fullness in the  joints and identify the embedded steel bars in the joints.
