KG pipe or similar

Hello

I am searching all over the internet, but I haven’t found anything completely satisfactory yet. For my geothermal system, four pipes go vertically into the ground. As luck would have it, I am currently building a cellar right next to these pipes. The pipes are about 30 cm next to the outside wall of the cellar. Now that the pipes are exposed, I want to protect them additionally before filling the cavity. The first thing that comes to mind for me is a 30mm KG pipe. Fill the KG pipe with sand, and they would be safe for the next 100 years. And now my concern: I need the KG pipe cut open. I can probably do it myself in an emergency. I would first try to slit one side and bend it open a little, put the pipes in, and then close the KG pipe again. What do you think, are KG pipes flexible like that? I would need to bend it apart by about 3-4 cm. Then glue it? With what? And if I have to cut open both sides, is there something similar to hose clamps in that diameter so I can fix the KG pipes before gluing? I am open to other ideas without KG pipes.

Are these brine pipes or even probes? I haven't figured it out yet.

Hello Ales

These are the brine pipes. They run horizontally away from the house and about 5 meters further they go vertically into the ground. I assume that they transition somewhere deeper into a probe (whatever that is). During the construction of the basement, I exposed the pipes. I first surrounded the vertical ones with insulation (those foam tubes for insulating heating pipes). However, I want to protect the pipes that will be covered with soil again a bit more. That’s when I came up with the idea of using split KG pipes.

I want to provide a bit more protection for the pipes that will be covered again with soil. That's how I came up with the idea of using slitted KG pipes.

It is sufficient for protection to cover with a half pipe on top.

It is enough for protection to cover it with a half pipe on top.

But if you lay a half pipe on the line, significantly more weight rests on the pipe as a result?
I wonder why the brine line was not laid directly in a pipe during installation. I thought that was standard.

The pressure on the pipe depends (only) on the mass above it. I assumed that the pipe would initially be covered with sand, then a half pipe is pressed on it, and then covered with soil (garden?). The half pipe serves only for mechanical protection. Whether that is necessary ...??

What does the heating engineer say?
