Hello!

I recently had a water damage issue. The drain pipe in the shaft to the upper floor was the culprit. I broke open the shaft and removed the drain pipe and the water pipe.

Now I'm renovating the basement and am about to plaster the walls. I really want to get this done soon so I can start painting, but there’s a hole in the wall where the pipes used to be.

I'm considering whether it would work to build in a piece of the drain pipe so that it extends a bit into the basement and a bit above the hole so I can continue with the drainage upwards when I eventually start with the bathroom there. And then connect in the basement once the painting is done.
Water, electricity, and the central vacuum system also need to go that way, and now I'm thinking about how to do this best. One idea I have is to build in either a PEM hose or one or two drain pipes to then be able to run things through them.

Any more tips?

Anyone have any suggestions?
Checked now and a channel with extra drain pipes will be cramped.

Let's see if I've interpreted it correctly.....
I think it's enough for you to make a drum... that is, don't seal it completely.... If you want it silent, just insulate the passageway.
 
I'm casting in the pipe that runs in the ceiling so that I can extend it upwards when I start with the toilet. For the electricity, I'm casting in three conduits in which I can pull the cables, and then I was thinking of either casting in PEM or that kind of yellow conduit used for cables, for the potable water. Or should I cast in that protective conduit used for RIR, but then you end up with a tricky joint later on... It must be better to cast in something for the water where you can pull an RIR.

I personally think it's safer with flexible pipes... But you do as you wish...
I just think you're putting in too much work... Think about it, 98% of all water pipes typically run through roads or wooden joists.
Only in a cast slab are they embedded...
 
If I make a drum for the drain, I have to cast a 160 pipe and it probably won't fit.
And I might have been a little wrong when I said plaster it closed. It's just that I need to fill in the hole in the basement wall.
Put the pipes in, then straw mat and plaster on them. Or shape small brick pieces. It's just so that there's not a big irregularly shaped hole on the wall.
In the beam layer, it's free. So it's just a little plaster on the wall that needs to go up.

The two white pipes are intended for water and underfloor heating. I hope they fit :)

Looks like you used 40mm plastic pipes and that should be enough to run double 17mm floor heating with supply & return, then you could have mounted the 110mm sewage pipe a bit straighter ,-)

Looks good.

I think the camera makes it look more tilted than it is :)
It comes out crooked through the wall because of things that were in the way. Then it goes straight down into the slab.

Looks good as mentioned....
