DIY pullup bar in apartment corridor

hello, I'd like to ask for your help.

I would like to install an apparatus so I can do some basic bodyweight exercises. I intend to hang gymnastics rings from the tube. I do not intend to use it for dynamic exercises with momentum etc, just pullups, dips etc. No fancy stuff that use momentum/kipping.

The setting:

corridor, 1,3m (4,3') wide

one side is concrete, the other is hollow bricks +plaster, etc.

I intend to install a steel tube, heavy duty.

Now, what's the best way to do it?

My plan so far is

a steel tube that's 15 cm larger than the width of the corridor (both walls are 12cm or so wide)

make 2 holes on each side, at least 8 cm deep, allow some slack so I can actually put the tube in.

clean them, fill them with epoxy adhesive for concrete-metal (I can't find a link in english, basically it is a compound similar to stucco in its texture that's actually harder than concrete when it gets dry). Basically I fill the holes with that, stick the tube inside, fill it again if there's empty spots, let it dry. Afterwards I reapply plaster and paint.

So my question, will this be safe in the long run? I am asking mostly about the side with the bricks. If not, what's the plan?

I cannot put something in the ceiling, like anchor bolts or similar, for a number of reasons.
