With the continuous progress of construction technology and material technology, underground drainage network has been developing rapidly in recent years. The pipes, interface forms and pipeline foundations of underground drainage network are gradually diversified, and the location of pipelines is different.   

In addition, in the transfer of authority and daily maintenance, the drainage network is also faced with situations that may need to know the quality of pipelines at any time. All these require higher and higher requirements for pipeline acceptance methods.   

" style="box-sizing: border-box">Pipe inspection robot Endoscopy CCTV technology has been developing for more than half a century since it was born in Europe in the 50s of last century. Since the entry into China in 90s of last century, more and more applications have been applied to the drainage pipeline maintenance industry.   

Because of the serious flood season in some sections of urban roads, it is necessary to understand the status of the municipal drainage network system in a short time. And the pipeline problem is universal. Therefore, in order to provide a complete solution, the advanced drainage pipe endoscope CCTV detection system and the QV pipe periscope device are used to check the rainwater pipe network of the corresponding sections.   

Th🍌e main methods of pipeline inspection are as foll🐠ows:

1. first, through the conventional measuring equipment, we get the detailed data of the ground height of the pipe system, the coordinates of the inspection well, the depth of the pipe and the diameter of the pipe. It provides data basis for later analysis of GIS system through official website.   

2. then the SINGA300 robot CCTV detection device is used for video detection from upstream to downstream. It includes detecting the connecting pipe of the rainwater inlet, storing the test results in two ways: video recording and photo capturing. In addition to reacting to the actual condition of the detected pipeline, the scene pictures can also display the location information and detection time of the pipeline through input mode.   

3. combined with the pipeline geographic information data and CCTV test results, a comprehensive analysis of the pipeline situation is made, aiming at different situations, solutions to the rectification plan are put forward.   

Through the key investigation of the drainage network in different locations, the technical personnel not only have an in-depth understanding of the use of the equipment, but also make rational use of the CCTV detection equipment in other key investigation projects. For example, in the process of detecting the drainage pipe on the part of the pavement with cracks, the use of CCTV detector can quickly determine whether there is leakage in the pipeline below the road.
