Common detection methods of urban sewage pipes

To a certain extent, it reflects the city's ability to withstand daily sewage and flood disasters, and is closely related to people's lives. But how to ensure the health of the drainage pipe? With the passage of time, the city's drainage pipes will appear aging, damage and other problems, or when the rainy season comes, how to do some preventive maintenance work, how to quickly find the problem, eliminate the problem? Drainage pipeline testing in our country has been in development for a period of time, in the earliest people use the most traditional detection methods, that is, manually drilled into the drainage pipeline by visual inspection or some simple tools for maintenance, such a way is not only inefficient, easy to pose a threat to the personal safety of the inspection personnel, and some small pipeline inspection personnel simply can not go in. Once the pipeline has a problem, it can only be excavated in a large area to find the fault point, which is extremely time-consuming and labor-intensive. With the development of science and technology, CCTV closed-circuit television detection method has gradually entered people's vision. Simply speaking, a camera device is equipped on a walking car, and the power car carries the camera into the pipeline to be inspected to record video, and then the video data is transmitted through wired or wireless means. Through the subsequent technical analysis of the image data, it is used as the basis for pipeline maintenance. At present, this technology has become mature and has brought revolutionary changes to urban sewage pipe inspection.
