Hello
I’ve been searching online extensively, but I haven’t found anything completely satisfactory yet.
For my geothermal system, there are four pipes running vertically into the ground. As luck would have it, I’m currently building a basement right next to these pipes. The pipes are about 30cm (12 inches) from the exterior basement wall. Now that the pipes are exposed, I want to provide extra protection for them before backfilling the space. My first thought was to use a 30mm (1.2 inch) PVC drain pipe. Filling the PVC pipe with sand would keep the pipes safe for the next 100 years.
Now, here’s my question: I need to cut the PVC pipe lengthwise. I could probably do this myself. I would first try to slit one side and bend it open slightly, slide the pipes in, and then close the PVC pipe again.
Do you think PVC pipes are flexible enough for this? I’d have to bend it open about 3–4cm (1–1.6 inches). Then glue it? What adhesive would you recommend?
And if I have to cut both sides, is there something like hose clamps available in that diameter to hold the PVC pipe in place before gluing?
I’m also open to other suggestions that don’t involve using PVC pipe.

Hello Ales
These are the brine pipes. They run horizontally away from the house and then go vertically into the ground about 5 meters (16 feet) further. I assume they continue deeper into a probe (whatever that is). During the construction of the basement, I exposed the pipes. For now, I have wrapped the vertical sections with insulation (those foam tubes used for insulating heating pipes). However, I want to provide additional protection for the pipes that will be covered again with soil. That’s how I came up with the idea of using split PVC pipes.

I wonder why the brine pipe was not installed directly inside a conduit during construction. I thought that was standard practice.

Bieber081523 Feb 2017 19:50The pressure on the pipe depends (only) on the mass above it. I assumed the pipe would first be covered with sand, then a half-pipe would be placed on top, followed by backfilling with soil (garden?). The half-pipe is only for mechanical protection. Whether this is necessary...??
