アーム型トンネル点検システムの点検速度向上

抄録

We have developed three types of tunnel inspection system with combination of robotics, an acoustic analysis, and an image procession. These systems have robotic hammers and light-section cameras on a work platform to inspect tunnel lining concrete including zenith parts which are difficult to be inspected. Although these systems require a crane and an assembly location nearby the tunnel. So we developed a new system with swing and telescopic arm mounted on an aerial work vehicle, which can be used to inspect wall efficiently while the vehicle is running. The system does not require on-site assembly work and can equip the same hammer and camera of the ordinary type. In this report, we introduce the outline of the new system and operations tests in an actual tunnel inspection.
