| Summary: | 碩士 === 國立虎尾科技大學 === 工業工程與管理研究所 === 98 === Varieties of No-Dig Renewal Method applications internationally, in which Cured-In-Place Pipe Method (CIPP) is most widely use in repairing of existing pipelines for domestic and foreign. However, this construction method has threshold of technology transfer and application virtualization, and also belongs to the Renewal Method of pipelines which has higher level and risk construction technology.
In view of this, the study will be explored in the key element of risk influence on the operation process of CIPP Method through the view of professional construction technology team member in domestic ; Analyze three critical operation items: plant resin immerse operation of CIPP Method, inversion process and curing process etc, through the procedures of Failure Mode and Effects Analysis (FMEA). The obtained results including poor compatibility of resin and pipeline, poor vacuum extraction, resin mixing unevenly, measurement errors of plant personnel and filed-site, coating and nonwoven are peeled off, resin is hardening early, high inversion potential energy, heat temperature and curing water level are controlled improperly etc., which are major failure of critical operation. Therefore, through the results this research and prevent and correction action. Failure is expected to be prevented in advance , and thus to enhance the reliability of application of this method in domestic.
