Abstract
Drainage pipe network engineering is an important part of the water environment treatment project. The pipeline inspection and repair are complicated and difficult duo to its conceal. The authenticity, accuracy and scientificity of drainage pipe inspection and evaluation are particularly significant. An advanced closed-circuit television (CCTV) technology was used for pipeline inspection of the Maozhou River Urban Water Environment Rehabilitation Project in Shenzhen. Through the pipeline inspection and evaluation integration process, the functional and structural defects, defect levels and specific locations of the pipelines were judged. According to the inspection results, the rehabilitation indexes of the corresponding defective pipelines were calculated, and the Pareto chart was combined to carry out the overall analysis, so that the quality problems were quantified and visualized, and the main factors causing the quality problems were determined. Finally, some corrective measures were taken in a targeted manner.
