ABSTRACT

Among the major underground structures in the metropolitan area, the rate of underground space occupied by water supply and sewerage facilities is 50 to 60 percent of the total underground storage space. In particular, because more than 90% of the road is laid underground, road accidents are caused by the combination of the normal load and frequency of use of the road, and various reasons such as the structural integration of old water and water pipes, the geological characteristics of the buried area, the precipitation and snow conditions, poor construction of the pipe, and the durability of the pipe according to the number of years that elapsed. Therefore, to understand the correlation between road falls and sewer pipes that occurred for seven years from 2010 to 2016, an important survey was conducted on the importance of setting weights to directly related workers such as experts in sewage areas, Seoul Metropolitan Government and the ward office, and the analysis results were weighted to establish a road map. According to the result analysis, the government planned to implement CCTV, visual inspection, etc. and present systematic and efficient maintenance measures by establishing priority areas for maintenance of sewer pipes. The plan is to present measures for improvement of sewerage maintenance policies and measures for responding to natural disasters through the enhancement of DB information, as well as sensors, asset management, and the improvement of water supply systems.
