Abstract:

The underwater inspection is a necessary technique in daily management, emergency rescue and dam safety assessment of water conservancy projects. Aiming at the difficulties in the underwater detect and by combining with ROV's advantages and characteristics, through the application cases of ROV system in dams, sluices and other water conservancy projects, the application approaches and achievements of ROV in the centralized leakage detection of reservoir (sluice), underwater metal component corrosion detection, concrete slab crack inspection, scouring pit detection of energy dissipation pool，underwater sonar scanning and imaging for structures were summarized, and the key technique, the application difficulties and applicability range of ROV were briefly discussed. The ROV technique provides a new scientific and efficient approach for identifying underwater hidden danger of water conservancy projects.

Key words: ROV, underwater detect, sonar scanning and imaging, underwater hidden danger
