Urban Sewerage Systematic Testing Project

Urban sewerage systematic testing project, through the introduction of intelligent testing equipment and digital management tools, the main city underground drainage network to carry out a "full-body physical examination", marking the management of urban infrastructure into a new stage of intellectualization.

The inspection uses CCTV pipeline robot, QV periscope and sonar imaging technology, which can accurately identify the internal structural damage of the pipeline, siltation and blockage and rain and sewage mixing problems. During the inspection process, the tracked robot goes deep into the pipe wall to take high-definition images, and the technicians receive real-time data and generate 3D defect mapping, which improves the inspection efficiency by more than 5 times compared with the traditional manual method. Currently in the old community concentrated area found 21 pipe cracks, 14 misplaced leakage and other hidden problems, the municipal sector is according to the "one pipe, one policy" principle of the development of repair programs.

"Underground pipe network as the city 'intestines', small hidden problems may trigger road subsidence, sewage backup and other chain reactions." City Drainage Management Office responsible person, the project supporting the construction of the pipe network GIS information platform, to realize the detection of dynamic data updates and intelligent early warning. The future will establish a three-year cycle of normalized detection mechanism, synchronized with the promotion of rain and sewage diversion renovation, is expected to make the pipe network overwater capacity by 40%, the risk of urban flooding reduced by 30%.
