With the continuous progress of construction technology and material technology, the underground drainage network has been developed by leaps and bounds in recent years. Underground drainage pipe network, pipe materials, interface types and pipe foundations are gradually diversified, and the geological conditions of the locations of the pipes are different.
In addition, during the transfer of authority and daily maintenance, the drainage network is also faced with the situation that may need to know the quality of the pipe at any time, which puts forward more and higher requirements on the pipe acceptance method.
Pipeline robot endoscopic CCTV inspection technology has experienced more than half a century of development since its birth in Europe in the 1950s, and more and more applications have been applied in the drainage pipe maintenance industry.
As some sections of urban roads often have serious water accumulation during flood seasons, it is necessary to understand the status of the municipal drainage pipe network system in a short period of time. In addition, pipe problems are universal. Therefore, in order to provide a complete solution, the advanced drainage pipe endoscopic camera CCTV inspection system is used with QV pipe periscope equipment to inspect the rainwater pipe network of the corresponding road section.
1. First, obtain detailed data such as ground elevation of the pipe system, inspection well coordinates, pipe buried depth, and pipe diameter through conventional measurement equipment.
2. Then use pipeline robot to perform video inspection on the pipe from upstream to downstream once, including the detection of connecting pipes of rainwater outlets, and the detection results are stored in two ways: video and picture capture. In addition to reflecting the actual conditions in the pipe being inspected, the on-site pictures can also display the location information and inspection time of the pipe through input.
3. Finally, combine the pipe geographic information data and the CCTV inspection results to conduct a comprehensive analysis of the pipe situation, and propose solutions for the different situations that appear.
Through the key inspections of the drainage pipe network in different locations, the technicians not only have an in-depth understanding of the use of the equipment, but also make reasonable use of the CCTV inspection equipment in some other key inspection projects. For example, in the process of detecting drainage pipes on some cracked roads, the use of CCTV inspection equipment can quickly determine whether there is leakage in the pipe under the road.
