[0002] Pipeline CCTV (Closed Circuit Television) inspection, introduced in China in the mid-1990s for monitoring internal pipeline conditions and drainage pipeline health, is the most advanced and effective method for pipeline health monitoring internationally. Developed countries like Europe and the United States have adopted this method as an effective tool for drainage pipeline health inspections and the acceptance of newly built drainage channels. Pipeline CCTV inspection utilizes an advanced CCTV pipeline endoscopic television inspection system that automatically crawls inside the pipeline, detecting and recording conditions such as rust, scaling corrosion, perforations, and cracks. This system simultaneously records the pipeline's internal conditions, transforming hidden underground pipelines into a computer-viewable internal video. This allows management departments to develop the most appropriate pipeline treatment plan based on the pipeline's condition, and further evaluation based on inspection technical regulations, providing a crucial basis for developing repair plans.
