碩士 === 國立中央大學 === 土木工程研究所 === 89 === Microtunneling method has become the unique choice for connecting the underground sewer mains and households. Microtunneling is versatile and robust is snaking around existing pipelines already crowded in urban areas. However, construction quality is an imminent problem in microtunneling, since supervision of underground work remains both costly and ineffective. Common quality defects in sewer pipe construction include leakage in connections, poor slope control and road collapse due to excavation.. These defects either create safety issues to the public as well as the workers or risk shortening the life of sewer pipes. Tackling these problems will require great effort in work supervision.. However, supervising underground work usually consumes more technical manpower than sewer systems owner can afford. This study provide a new paradigm in underground work supervision.. A real-time construction work supervision procedure is proposed. The procedure bases its effectiveness upon wireless communication. First, the work is videotaped in a digital format. Detailed videotaping procedures are given.. The visual output is then transmitted via wireless communication tools, such a PHS or GPS mobile phone, to a central website. The website operator will inventory the arriving files according to a pre-determined file management system. With this procedure, site supervisors can monitor more sites with less effort. Personal visits will be directed to construction sites which reveal particular concerns. This work has proven the procedure feasible and tentative estimates also verify its cost effectiveness.
