碩士 / 國立高雄應用科技大學 / 土木工程與防災科技研究所 / 101 / Water resources amount increase fast since 60’s in Taiwan because of the industry development and people living demands. And the wastewater drained into rivers had caused pollution. Large amount of public construction funds were invested in sewage piping systems and treatment plants for improving river quality. However, sewage piping systems often had crack, blocking, collapse and other defect or damage after long-term use. In order to early detect the pipe faults, regular inspection and maintenance is necessary. However, regardless the pipe damage extend and maintenance method, maintain normal operation of sewer system is the main purpose under limited funds.
In this study, Dafa Industrial Park sewer system inspection, completed in 2010, was served as the case study. Through statistical analysis, three main defects of sewer pipes were root penetration, mineral/concrete sedimentary, and O-link shedding, which occurred average 5.9, 5.6 and 2.5 anomalies per kilometer respectively. The total average sewer pipeline defects in Dafa Industrial Park were 14.78 anomalies per kilometer, and this amount were much higher than the average amount 1.5 anomalies per kilometer of thirteen Industrial Parks in southern Taiwan from official report "Final Report of Preliminary Planning of Industrial Park Sewage Pipelines Replacement and Sewage Treatment Plant Expansion and Upgrade", published by the Industrial Development Bureau, Ministry of Economic Affairs, in 2010. In Dafa Industrial Park, sewer pipe with diameter 200mm, and 700mm had average defects 20.8, and 23.5 respectively, which were higher than that of total average amount. And sewer pipe with diameter 250mm, and 300mm had average defects 14.7, and 15.3 respectively, which were close to that of total average amount.
According to the analysis, we suggest that the inspection frequency should be different for different pipe diameters. In planning a new Industrial Park, species selection and planting location should consider carefully to avoid root penetration. Increasing both inspection frequency of wastewater emission and small diameter sewer pipe may reduce the chance of mineral/concrete sedimentary.
