When a new channel is created, once the construction is completed, the line cannot be used yet, until the slope of the channel is checked. The channel pressure test must be submitted to, and its slope must be measured. The canal slope measurement was developed for this purpose only, can be done with a so-called self-propelled camera.
With a self-propelled channel camera 160 We can measure from a pipe diameter of mm 2000 mm-ig. The self-propelled cameras they work like that, that the four-wheel camera has a pendulum, if the camera body tilts forward, then the pendulum swings forward and shows the given negative value to the central unit, so the channel goes down. Has a camera the front of the body is up, then the pendulum swings backwards, shows the given plus value to the central unit, so the channel is rising, or the slope is not suitable. The camera uses the signal provided by the pendulum to print the slope graph of the given section on a graph, where the slope of the given section is shown in percentage, and a protocol, as you can see:
– channel slope, or increase in percent, or in millimeters
– numbering of a given section, pl.: SZ1-0-1 (This is a sewer section numbering)
– mine numbers within a section, pl.: SZ14-SZ15 (14-and we go from mine to 15)
– name of the customer
– where we did the test (test address)
– who performed the test
– channel diameter in millimeters, e.g: 200 mm
– channel material: kgpvc, concrete, vas, eternit other
When measuring the slope of a channel, we do not only examine the slope! In such cases, we also place great emphasis on examining the internal condition.
Important, that:
-
- the sealing ring must not be turned inside out
-
- the casing should be well slid together
-
- fracture, crack, impression, whitening should not be visible!
-
- cleaned, be a channel prepared for examination
A cleaning very important, because the self-propelled camera needs a clean surface for accurate measurement!
When the test is finished, the video is recorded on a DVD, or on a USB flash drive, together with the protocol and the slope diagram, we print it and give it to the customer, who forwards it to the appropriate person. The person in charge will analyze it, and make the decision. The channel is adequate or needs to be improved.
