Abstract: The dam culvert is an important discharge structure for reservoir irrigation and water supply. In the process of perennial use, the dam culvert are affected by the durability of materials, construction quality, operating conditions and other factors, and then encounter varying degree of disease, such as leakage, structural damage and sedimentation. For many small dam culvert, because of small diameter and structure aging, manned detection is difficult. Based on the investigation of culvert operation and detection technology, a dam culvert detection system is developed. The system has the functions including leakage detection, defect inspection, pipe diameter measurement, 3D model construction, pipe diameter and sedimentation measurement, which has greatly improved the dam culvert detection efficiency and reduced the risk and difficulty of detection. The reliability of the detection system is verified by engineering practice, which provides a new solution for non-destructive and efficient detection of dam culvert.
