Urban drainage pipe network is an important part of urban water pollution prevention and control, urban drainage and flood control, and is also an indispensable and important infrastructure for modern cities. The drainage pipe network is not only an important channel for collecting and transporting urban rain and sewage, but also an invisible livelihood project.
In order to alleviate problems such as urban waterlogging and sewage overflow in recent years, on the basis of ensuring the safety of people's lives and property and the safety of urban operation, most cities have carried out systematic investigations such as general surveys of drainage pipe networks, dredging, and testing. Clear the drainage pipe network under the bottom, accurately find the problems in the pipe network, lay a solid foundation for the follow-up water environment treatment work, and provide detailed and reliable basic information.
The investigation content mainly consists of four parts:
1. Pipeline network survey: Through detection, clarify the purpose of the pipe network (rainwater pipes, sewage pipes, confluence pipes) and the physical data of the pipes (position, pipe diameter, well location, well depth, drainage, etc.).
2. Pipeline desilting: Desilting by means of high-pressure dredging and cleaning vehicles can not only make the rainwater and sewage pipe network unimpeded, but also provide working conditions for CCTV detection robots.
3. Pipe network inspection: use industrial endoscopes, CCTV inspection robots, pipe periscopes (QV) and other modern technological means to conduct investigations, and can issue inspection videos and defect diagnosis reports in time to find problems in the pipeline.
4. Establish drainage pipe network GIS system: pipe network census data→drainage pipe network database→drainage pipe network GIS system (realize "one map" dynamic management of drainage pipe network)
The industrial endoscopes independently developed and produced by Zhimin Technology can effectively help the municipal work in the inspection and testing of small and medium-sized pipe networks, and bring convenience to technology.
