- Abstract:
- To further control the leakage problem of water supply pipeline networks, after analyzing the advantages and disadvantages of different detection technologies, Chengdu Municipal Waterworks Co., Ltd. has learned that the internal inspection technology for pressure pipelines has high implementability for leak detection of large-scale water transmission pipelines. Firstly, through comparative experiments, the internal inspection equipment suitable for the working environment was selected. Combined with the flow measurement and evaluation results, a certain important water transmission pipeline was determined as the detection object. Then, based on the visual analysis of the sound signal at leakage points and the excavation situation, the high accuracy of this technology in evaluating the size of leakage points was verified, and the leaked water volume and economic benefits were statistically analyzed. The detection results show that the internal inspection technology for pressure pipelines meets the leak detection requirements of large?scale water transmission pipelines, but the detection equipment still needs to be further optimized and improved.
