How is video diagnostics sewage
Any construction is simply impossible without communications systems that turn an ordinary concrete box into a residential or industrial building filled with energy. These include plumbing, electricity supply, ventilation shafts, as well as sewers, without which it is difficult to imagine a normal urban structure. In this article we will talk about the latter, and find out how and when video diagnostics of sewage is carried out.
What it is
Teleinspection of sewer pipelines is a survey of their inner surface for deposits, blockages, foreign objects and other possible emergency cases. In this case, you will know exactly where the trouble occurred and its type.
The system can operate at a depth of 10 m in pipelines OO 50-1200 mm. Video inspection of sewage is a fast and accurate way to diagnose utilities, the ability to get rid of sand, silt and small debris with minimal cost.
General information
Most of us understand that if the operation of pipelines, which discharge drains, worsens their work, it will begin to pose a threat to health. In this regard, they must be cleaned regularly to comply with sanitary standards. Of the many ways to determine the locations of blockages today we will consider one called video diagnostics of sewer pipes.
Such systems do not differ in originality from each other, each has:
- mini camera with light, which is lowered into the tube;
- pushing cord to help it move;
- a wire connecting the camera to the operator’s monitor.
Tip: when choosing equipment, pay attention to the camera's backlight so that it is bright and preferably economical, especially when the power is supplied from the battery.
Manufacturers are experimenting with a design that allows the camera to constantly remain in the center of the pipeline so that it can transmit the most complete picture. For this, special centering spheres can be used, which do not allow it to “crawl” to the wall.
Many video heads are arranged in such a way that they make it possible to pass smooth sections of the pipeline and overcome turns at a right angle, and the diameter of the sewer pipes plays a big role. There are also devices that allow the operator to know exactly where the head is now.
Tip: do not carry out such a diagnosis with your own hands, it is better to entrust the work to specialists.
Information monitors offer operators a color image, but the black-and-white picture is better suited for the latter’s poor contrast. Therefore, many have a special function to switch from color to black and white.
The image quality on the monitor is closely related to the video inspection model, on which the price of equipment also depends. Information obtained from the camera is also recorded on removable media or an integrated memory card for later viewing.
There are also models that are capable, in addition to recording video, to take pictures of the desired places. Video inspection systems must have an appropriate protection class due to working in polluted or wet environments.
When used
Teleinspection of sewer pipes is used in the following points:
| Quality checking | After completing the construction of the sewage system, it is required to present evidence of high-quality work. A simple viewing of the pipes to the light will not make it clear, unlike the video inspection, which will clearly show that in the pipes:
|
| Condition monitoring | When retrofitting or tapping into existing water supply systems, it is necessary to know for sure that all the required technical conditions are met in order to perform such actions. The instruction states that in this case you can monitor the state of the system in real time in this case. |
| Obstacle detection | The camera makes it possible to identify a blockage in the sewer system, as well as to detect the reason for which it appeared:
|
| Unauthorized tie-in | Television sewer surveys help eliminate suspicions such as illegal tapping. Such unauthorized actions, ordinary viewing of pipes through the lumen cannot confirm this. |
Additionally
- Using video inspection allows you to restore the layout of internal communications, located under the floor or in the wall, if they were lost.
- Video diagnostics of sewer pipes will make it possible to understand why large bills began to appear for the flow of coolant or water, determining where a pipeline defect might be.
- In addition to the sewage system, you can solve the problem with the chimney, which creates bad traction, which is why the smoke does not leave the heater so quickly and find out where the blockage has formed. Also, the video head will be a real help in determining the overlap of the ventilation channel.
Methods of video inspection
Teleinspection of sewage is carried out using two types of systems:
- Pushed through - provide an opportunity to inspect pipelines of small diameters.
The system kit consists of:
- control panel;
- glass rod, moving a miniature camera and transmitting the image on the monitor screen.
- Robotic complexes, inspection pipe of any size outside and inside. In this case, the camera is installed on a self-propelled platform, and the control is performed by a special remote control.
Conclusion
From the article it became clear that the use of video diagnostics of sewer networks makes it possible to quickly, accurately and with minimal loss of time to find trouble and understand why it happened. In addition, the opportunity to respond in time to a possible violation of the pipeline, if periodically organize its inspection using a television camera.
