Development of Laser Scanning System for Aging Inspection of Box Culvert

The construction of box culvert for electric power transmission is increasing more and more, and the life extension of it is very important. The development of structural maintenance system in view of structural integrity evaluation is needed and widely discussed. Therefore, Laser Scanning System is developed for the inspection of aging phenomena such as crack, exfoliation, and water leakage of Box Culvert. This system made progress in maintenance technology for box culvert and have various kinds of advantages comparing with conventional method by visual inspection.
