| 摘要： | Three leak detection/location technologies were demonstrated on a 76-year-old, 2,057-ft-long portion of a cement-lined, 24-in. cast iron water main in Louisville, KY. This activity was part of a series of field demonstrations of innovative leak detection/location and condition assessment technologies sponsored by the U.S. Environmental Protection Agency (EPA). The main goal of the demonstrations was to acquire a snapshot of the current performance capability and cost of these innovative technologies under real-world pipeline conditions so that technology developers, technology vendors, research-support organizations, and the user community can make more informed decisions about the strengths, weaknesses, and need for further advancement of these technologies. Leak detection was one part of a comprehensive water pipeline condition assessment demonstration where six inspection companies operated 12 technologies that were at various stages of development and provided different types and levels of leak and/or structural condition data. Technologies were included for wall-thickness screening (i.e., average wall loss over many tens of feet), for detailed mapping of wall thickness, and for leak detection. Both in-line and external inspection technologies were demonstrated. The inspection technologies used visual, mechanical, acoustic, ultrasonic, and electromagnetic methods for acquiring leak and pipe condition data. The inspection results for each technology were compared to the leak rates or dimensions of introduced and naturally occurring anomalies, as well as their location along the pipeline. |
