The internal surface of the drainage pipe now contacts various kinds of process media. It is easy to bond, deposit, deposit various materials, and even cause blockage of pipes. The drainage pipeline is buried deep underground once the drainage is poor." style="box-sizing: border-box;background: transparent">Periscope for pipeline inspection Maintenance personnel often have to dig large areas to find out the location and cause of the blockage.   

The drainage pipeline is overhauled, and the pipe diameter of the drainage pipe is too small, the pipeline is misplaced, the pipeline is silted up, the pipes are not connected and false rainwater outlets, and the unqualified inspection wells and rainwater outlets are checked out one by one. In the actual pipeline maintenance engineering, there are inevitably many different construction environments. Drainage pipes are buried underground, crisscrossing, and when problems arise, it is extremely difficult to find out the leak points.   

The introduction of the electronic video industrial pipeline endoscope examination can not only see whether the pipeline is smooth, but also can grasp the specific reasons and the specific location of the pipeline obstruction at the first time. The introduction of electronic video industrial pipeline endoscopy to the urban drainage system can complete the sewerage examination and maintenance of the road with larger traffic volume and larger traffic volume.   

As an important part of nondestructive testing tools, pipe endoscope plays an important role in pipeline maintenance. If the pipeline is fragmented or debris accumulation is blocked, will the blockage be located in the pipeline or in the rainwater well, thereby greatly reducing the scope of road excavation, making the daily maintenance and emergency repair of the road drainage pipeline more convenient.
