Canal slope measurement, canal inspection with self-propelled camera

Csatorna lejtés mérés, csatorna vizsgálat önjáró kamerával

When a new channel is constructed, the pipe cannot be used until the channel slope has been checked after construction is complete. The channel for pressure testing The slope of the canal can only be measured with a so-called self-propelled camera developed for this purpose.

With a self-propelled sewer camera, we can measure from a pipe diameter of 160 mm up to 2000 mm. The self-propelled cameras They work in such a way that there is a pendulum in the four-wheeled camera, if the camera body tilts forward, the pendulum swings forward and shows the given minus value to the central unit, so the channel goes down. If the camera the front of the body is facing upwards, then the pendulum swings backwards, showing the central unit the given plus value, so the channel is rising, or its slope is not appropriate. The camera uses the signal transmitted by the pendulum to print the slope graph of the given section on a graph, which shows the slope of the given section in percentage, as well as a report showing:

– channel slope or rise in thousandths or millimeters

– numbering of a given section, e.g.: SZ1-0-1 (This is a sewage canal section numbering)

– shaft numbers within the section, e.g.: SZ14-SZ15 (we go from shaft 14 to 15)

– the name of the customer

– where was the test conducted (test title)

– who conducted the investigation

channel diameter in millimeters e.g. 200 mm

– channel material: kgpvc, concrete, iron, eternit other

When measuring the slope of a canal, we don't just examine the slope! In such cases, we also place great emphasis on examining the internal condition.

It is important that:

    • the sealing ring should not be turned inside out
    • the casing should be well slid together
    • No breakage, cracks, dents or whitening should be visible!
    • the canal should be cleaned and prepared for examination

THE cleaning This is very important, as the self-propelled camera needs a clean surface for accurate measurement!

When the inspection is complete, the video recording is printed out on a DVD or pendrive, along with the report and the slope diagram, and is given to the customer, who forwards it to the appropriate person. The person in charge analyzes it and makes a decision. Is the channel satisfactory or does it need to be repaired?
