Title: Cable Routing to Garage: 5x4mm, Paving Stones, Concrete, Arot/PE Pipes & Winter Concerns

Hello. I need to run a 5x4mm? cable to the garage, unfortunately the only way is through the paving stones, under which there is a lot of concrete, and under the concrete there is stone and rubble. Standard disassembly of the cube, digging a ditch in this case will be expensive, laborious with a lot of mess, and in the end the cube will sit down under the pressure of trucks that sometimes have to drive in (some say that if it's done right, nothing will sit down, but once I had to disassemble a piece of paving stone, dig a hole and despite a decent compaction of the material, the paving stone sat in this place), so it's 100% out and I'll fix the cable by air sooner.
But, I came up with the idea to pull out a row of cubes, cut a groove about 10 cm deep, put arot or PE pipe in it, and then pour concrete. I'm just wondering if water will collect there, which could damage the cable in the winter. Or maybe lay the ground cable itself, without additional protection? But then I would be afraid that it might rub against the concrete. I know that this is not professional workmanship and you should dig a pit, lay the ground wire at a depth of 90 cm, and cover it with sand, but I do it at home, I would not dare to do such a combination at someone else's. What do you think? Regards.
I've attached a picture that shows a bit of my vision.

This tube will crumble over time. I would have used a pessicle before.

The conduit is not suitable for this type of work. Arot casing pipe at the right depth: https://www.wavin.com/pl-pl/katalogty/energetyka

AROT pipe !!!!!!! And not a corrugated pipe or tubes!!!!

I would give a dedicated rigid casing pipe (for example: SRS pipe made by TT Plast - or something similar from another company) - a cable in the "ground" version, i.e. YKY, if we are very paranoid, we can put AROT pipe to the rigid pipe and pull it into it cable

If you make a groove and pour concrete into the pipe, it should withstand - should - this is the key word

I also think that it should withstand, because the cube will still be based on concrete that would not be cut out, but I wonder if water will not collect there, which in winter can cause damage to the cable insulation when it freezes.

On what standards is this proposed bungling supposed to be based???

None, but it's not about standards, because we won't take care of it from the forum level anyway. I would like to mention that the YKY 0.6/1 kV 5x4mm? cable has a diameter of only 1.5 cm, so the gap needed for its laying is really small. Instead of flooding the gap with concrete, it would be enough to even cover it with sand and lay the cube. Water is not a threat to this cable.

You worry about the fact that we won't take care of anything from the forum level, and you post an even more bungling solution yourself.
Will you sign as a contractor under what you proposed???

So think about how many people, not boasting about it, will implement such a solution, taking it at face value?
This is brainwashing.

I know it's not a perfect solution, but I do it myself and I take responsibility for it.

Then go to the author of the thread and do it to him, not write what you do in your yard.
As for the solution, it's pure paradox.

He's the author. And 20-30 cm of concrete under the ankle is definitely water-permeable concrete? At home, I would do as in the drawing, but in half of the concrete and strong concrete the rest as my colleagues indicated. The sand can be washed out over time and still the cube would still work. Of course, this is not an area where there can be a sudden overflow of water from above or is it not mining, etc.?

So do.
Also, write that any investments in a built-up area where sidewalks are dismantled, ditches are dug to lay cables at the right depth is stupid.
And yet, if the cable is so possible, what prevents you from laying gas in this way.
I asked about the standards sanctioning such bungling.
The fact that the inventive Dobromir advises so is not a standard.

He undresses because the contractor does not want to be held responsible for deviating from the standards, he has a project that he is supposed to stick to, a construction manager is standing over the contractor, etc.

Maybe my colleague kkas12 will write how it should be, because so far he has spoken 4 times and nothing. And how are they doing in Dublin? Because I saw - they do very different. Also, don't say anything that I didn't even mean. It's good that the author asked how to do it, that's what this forum is for, when I was doing it at home, those were the times when there was nothing, the electrode forum was not even there - not even in the plans. In public places there must be plans and very strict adherence to them. I believe that even in my area, so private, you should have a plan, do it according to standards. As for gas, many people made a lot of mistakes in Szczyrk. They were professionals

Twice I asked about standards allowing for the solution propagated here.
The answer was that there are no such because in professional companies, order is supervised by the construction manager and possible responsibility when bungling comes to light.
So do not write that proven solutions can be ignored in your area, because there are no standards for professionals and others for laymen.

Does damage to the insulation of the cable laid at the appropriate depth, until the protection is activated, pose a threat to third parties?
There is no such threat, because the current "escaping" to the ground will not be brought to the surface of the ground.

Now consider such damage in a cable laid several centimeters below the surface, i.e. in a solution that you are trying to force through.
You really can't see anything?

Then please take a receiver in the first class of protection, of course connected to the network, and walk along the route of the damaged cable in this mess, which you dream of doing so.


There are threads on this forum about "kicking" front doors, for example.
It is your "elder brothers in faith" without imagination that are the reason for their creation.
