Proposal of underground situation understanding for efficient maintenance in water pipe network

Abstract

In this paper, we propose the underground situation understanding for efficient maintenance in water pipe network. The buried pipes are corroded in underground situation, in the result, pipe wall thinning is occurred. Therefore, the thinning detection technology of pipe wall is important. In this research, we are conducting the development of diagnosis technology of pipe wall using the in-plane bending vibration mode of cylindrical shell. Moreover, the replacement program is considered using Geographic Information System and the result of the above diagnosis.
