Outline of Final Research Achievements

Many concrete structures are deteriorating to dangerous levels throughout Japan. A reconstruction of the structure is one solution to this problem. However, rebuilding an entire structure is difficult given recent economic conditions. In addition, with regard to CO2 reduction, repairing only the deteriorated parts is good for the environment. Because reconstruction of the entire structure generates a great deal more CO2 than the repair of the deteriorated parts, the former approach has a negative influence on the environment. Therefore, a method to correctly detect deterioration in the affected parts is required. Furthermore, many structures need to be inspected, and the inspection area is wide, therefore, inspection methods that are highly efficient are required.
In this study, we developed a testing machine using a multirotor UAV for tunnel inspection as an efficient inspection method.
