Review of Improvements for Efficient Maintenance of Corrugated Steel Structures constructed on Expressway
The corrugated steel plate culvert structure was developed and actively developed in the United States in the 1930s and was introduced into the domestic scene in the 1970s. Currently, about 1,000 corrugated steel structures were being used for expressway concrete passage culverts and waterway culverts. Compared to concrete materials that require a basic curing time, corrugated steel plates could be assembled and backfilled, so that the construction speed is fast and the economics were excellent. However, as the number of public years has elapsed, problems in maintenance have been found. Therefore, there is a growing interest in the stability of corrugated steel plate structures. Therefore, in this study, the improvement for the efficient maintenance of the corrugated steel structure constructed on the expressway was examined.
