摘要:	污水下水道建設為現代化都市公共工程建設重要之一環，攸關全民生活水準、國家競爭力、社區形象、環境衛生、國際觀瞻等，過去二十年來，政府投入大量經費興建都市地區污水下水道系統。依據經驗污水下水道管線鋪設完成，經過通水使用一段時期後，因缺乏定期維修或因當時施工不良、施工使用管材不當、地震衝擊、車輛載重等因素，造成日後對下水道管線系統服務功能影響甚鉅。為了解污水下水道管線服務功能是否達到預期，必須定期針對人孔及管線進行調查，再針對不同嚴重性質之管線段進行ＴＶ檢視工作，分析管線遭破壞狀況，再進行研擬修繕工法之作業，以能長期維持污水下水道管線系統之功能。若於都會區採用傳統開挖修繕工法，於施工期間須進行封閉道路之作業，易造成交通動線之阻礙、污染環境及影響附近居民生活品質，其所須付出之社會成本亦相當昂貴。而免開挖工法於近年來應用在污水下水道管線系統修繕工程上，對路面交通衝擊影響有很大之改善，該工法並具有低噪音、低震動、低污染之特色，已被陸續廣為應用。本文研究將對於蒐集應用於都會地區污水下水道管線之各類免開挖工修繕工法，進行分析其特性功能及適用範圍，另針對國內桃園縣林口特定區既有之污水下水道系統，進行修繕規劃之案例探討。 Sewerage construction is an important aspect of a modern city. It represents the living standard, national competition, public sanitary and international status of the country. In the previous twenty years. The government install a lot of budget to build up the sewerage network system. According to the experience of the finished sewer, after using a period of time, because of the shortage of periodic maintenance or improper construction and piping material used, earthquake impact and traffic loading etc. It would seriously affect the service function of the sewerage system. In order to know whether the system achieve the predicted function, periodic surveying of the manhole and the piping system is a must. Meanwhile, referring to the importance of different systems, we need further TV inspection work to analyze the damaged situation of the pipe as well the repairing method in order to maintain the long term normal function of the sewerage system. If we use the traditional open cut dredging method to repair the damaged pipe, in the construction period, the road need to be closed and causing serious traffic problem, environmental pollution and the impacts to the resident. It is a very expensive social capital. To avoid the above situation, non-open cut dredging method is used in the past several years. It can really improve the traffic impact. Its low noise, low vibration, low pollution characteristics make it gradually and widely used in recent year. In this studying report, we have collected different kinds of non-open cut dredging methods used in the sewerage system and analyzed the special function and suitable using scope of each method. On the other hand, we focused on Taoyaun Hsien Lin Kuo Special District existing sewerage system to discover the repairing planning of the system.
