With the continuous advancement of construction and material technology, theunderground drainage network has developed rapidly in recent years. The underground drainage pipe network pipe, interface form and pipeline foundation are gradually diversified, and the geological conditions of the pipeline are different.Pipe inspection crawler camera into being under such a background.

In addition, in the transfer of authority and daily maintenance, the drainage network is also faced with the situation that it is necessary to understand the quality of the pipeline at any time, which puts more and higher requirements on the pipeline acceptance method.

The CCTV inspection technology of pipeline robots(hereinafter referred to as pipe inspection crawler camera) has experienced more than half a century of development since its birth in Europe in the 1950s. Since entering China in the 1990s, more and more applications have been applied in the drainage pipeline maintenance industry.It was not until the past few years that Shandong China Coal Group promoted it that it was known to the entire drainage industry and gradually promoted it to the design and construction of drainage networks.

Since some sections of the urban road often have serious water accumulation in the flood season, it is necessary to understand the status of the municipal drainage network system in a short time. And the pipeline problem is universal, so in order to provide a complete solution, the advanced drainage pipe endoscopic camera CCTV detection system is used, and the QV pipeline periscope equipment is used to check the rainwater pipe network of the corresponding road section.

The main methods of pipe inspection crawler camera are as follows:

1. Firstly, through the conventional measuring equipment, obtain the ground elevation of the pipeline system, check the well coordinates, pipeline depth, pipe diameter and other detailed data. Provide a data foundation for the analysis through the official website GIS system.

2. Then, through the CCTV pipe inspection crawler camera, the pipeline is video-detected once from upstream to downstream. It includes a connecting pipe for detecting the gully, and stores the detection result by video recording and picture capturing. In addition to the actual conditions in the pipeline being tested, the live image can also display the position information and detection time of the pipeline by input.

3. Finally, combined with the pipeline geographic information data and pipe inspection crawler camera test results, the pipeline situation is comprehensively analyzed, and the rectification plan is proposed for different situations.

By focusing on the drainage network of different locations, technicians not only have a deep understanding of the use of equipment, but also make rational use of CCTV pipe inspection crawler camera in other key investigation projects. For example, in the process of detecting the drainage pipe on a part of the road surface where cracks occur, the CCTV pipe inspection crawler camera can quickly determine whether there is leakage or the like under the road.
