Description

Technical Field

[0001] The present invention relates to the technical field of concrete panel detection, and in particular to a method and a device for segmented detection and filling of cracks in underwater concrete panels in deep water areas. Background Art

[0002] In the construction of water conservancy projects, concrete face rockfill dams are widely used as an important structural form. However, with the continuous development of engineering technology and the complexity of the application environment, concrete panels are facing more severe challenges, especially in water conservancy projects in deep water areas. Underwater concrete panels in deep water areas are prone to damage such as cracks due to long-term underwater environment, affected by multiple factors such as water pressure, water flow scouring, temperature changes and foundation settlement. These cracks will not only affect the overall stability and safety of the dam body, but may also cause problems such as water seepage.

[0003] Traditionally, crack detection of underwater concrete panels in deep water areas is mainly carried out by divers carrying detection equipment. However, since the concrete panels are in deep water areas, this method not only has low detection efficiency, but also divers are limited by their own conditions (such as vision, physical strength, etc.) and environmental factors (such as water flow, visibility, etc.) when working underwater. They may not be able to accurately and comprehensively detect cracks on the concrete panels, and the detection accuracy is limited. Furthermore, after detecting cracks in the concrete panels, divers usually only mark the crack areas through marking equipment, and cannot process the crack areas in time. Subsequent divers are required to continue to enter the water to fill and repair the crack areas, which is more troublesome. To this end, we propose a segmented detection and filling method and device for underwater concrete panels in deep water areas. Summary of the invention
