KG pipe or similar

Hello Bieber

I have not consulted the heating engineer. Why should I? Everything I found while digging up the pipes does not speak well of him.
Half-pipe would work for the horizontally laid pipes, but I am not a fan of half measures. For the vertically laid ones, a full pipe is mandatory anyway.
Of course, I fill the KG pipes with sand to avoid damage from pressure.
I am looking for: Either an alternative to the KG pipes. There might be pipes consisting of two parts that are earth-resistant.
Or a tip on how the two halves can be rejoined. Tape, glue, or the like.

So, you will probably find it difficult, if at all possible, to bend a 30mm pipe wide enough to get it over the existing pipe, although I do not know the diameter of the existing pipe. It works with a pipe of a larger diameter, especially if you heat the pipe. I myself have already been able to bend a 110mm pipe a few centimeters apart without heating it in order to protect an existing water pipe.

Since I am not familiar with geothermal energy use, I am wondering why you want to fill the pipes with sand afterwards. Is that necessary or am I misunderstanding something?

Hello gardening friend

the brine pipes are about 30mm in diameter. Heating them is a good idea, I will try that. Normally, I assumed that the pipes lie in sand. But that was only theory. They partially used construction debris for filling. However, the pipes are extremely stable, so there is no damage. I will fill the KG pipes with sand to avoid unwanted cavities.
