- Abstract:
- Based on the comprehensive analysis of the district drainage system, drainage pipe network topology, and drainage household characteristics, the monitoring and diagnosis units were divided. The urban drainage network zoning-diagnostic work were carried out and the real status of drainage law and water quality in drainage network were obtained by combing with water quantity and quality monitoring techniques. The obtained monitoring data were cleaned and corrected. Inflow and infiltration problems in the district drainage network were assessed objectively, quantitatively and systematically based on dry weather water quantity and quality balance, dry and rainy day comparative analysis and other analytical techniques, thus the health of the network was reflected. The health of each monitoring unit was sorted and the priorities of the area for further inspection and transformation were clarified. Seizing the focus within a certain range and saving investment can be used as an important technical means of urban drainage network periodic inspection, to lay the foundation for targeted network repair and facility renovation work.
