Abstract

Abstract: The leakage of reinforced concrete has been a key factor to affect the quality of waterproof structures, and the leakage detection has been the focus and difficulty to be considered in waterproof structures. Aim at this situation, based on a practical project as a case, an infrared thermal imaging nondestructive detection (ITID) technology was applied to the leakage detection of a reinforced concrete pool structure (RCPS) in this study. The dual-light infrared thermal imager (ITI), based on unmanned aerial vehicle (UAV) platform, was used to detect the leakage of external wall of the structure. The effectiveness and reliability of leakage detection were analyzed and verified for ITID technology applied into RCPS. Results show a good detection effect is obtained, and a new choice for detecting the leakage of RCPS is proposed.
