摘要

在國際上，免開挖更生工法( No-Dig Renewal Method )之應用其種類繁多，其中以現地成形固化工法( Cured-In-Place Pipe Method；CIPP )為國內、外最被廣泛運用於既設管道之修復；因本工法具有技術轉移及應用授權之門檻，且係屬於施工技術層次與風險性稍高之管道更生工法技術；有鑑於此，本研究透過國內外專業施工技術團隊成員，針對現地成形固化工法之廠內樹脂浸透作業、現場反轉作業及內襯養治固化作業等三項關鍵作業要項，透過失效模式與效應分析( Failure Mode and Effects Analysis；FMEA )之程序做深入之探討。

研究結果顯示以樹脂與內襯管相容性不佳、真空抽取度不足、樹脂混合攪拌不均勻、廠內人員量測錯誤、實地現場量測錯誤、行水層與不織布剝離、樹脂提早硬化、反轉位能過高、加熱溫度控制不當、養治位能控制不當等10項，為本工法關鍵作業要項之失效主因；因此，期望透過本研究之成果及預防改善對策，於執行施作時均能事先被預防，以提高穩定之施工品質及降低施工風險，進而提升本工法在國內應用上之可靠度及杜絕工法執行之失效可能性。

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.
