Hello everyone,
I have a shaft (see attached picture) where I need to cast some kind of cover.
Explanation:
The red row of bricks will be removed.
The blue area will be the cover.
The yellow area is an access opening into the shaft.
It will be filled completely with water later on.
Do I need to install steel beams and then cast concrete with a thickness of about 20cm (8 inches)? I was thinking of drilling holes by core drilling and then sliding the steel beams in and embedding them into the wall with concrete.
Thanks for your feedback.

Remove the ceiling formwork with a circular opening of about 62cm (25 inches). Install supports and reinforcing steel as required by structural specifications. Proceed with concrete pouring.I’m not sure about the structural requirements, as I would actually prefer not to hire a structural engineer for such a minor issue who would then charge a substantial fee.I thought the information on what really matters might come from your experience.

I thought the information about what really matters could come from your experience.That’s why my suggestion is to use an FT type, as they come with standardized structural calculations.From experience, I’m also wondering how you plan to waterproof it? In the end, water will end up in the basement.
This will be done with PCI waterproofing for swimming pools. The relevant field service technician has already been here and has put together the products for me. A basement is located 3 meters (10 feet) away. Above is a swimming pool and to the right is a terrace.
I am not too concerned about the watertightness.
I could just lay the FT on top, but that is not possible because the wall on the right is about 60 cm (24 inches) higher, so it needs to go inside, not on top.

Is this a DIY project? Otherwise, your contractor should be responsible for handling it.
Without experience, you shouldn’t attempt a DIY project. Especially not with help from a forum.
Of course, I can tell you to place an 8 mm (5/16 inch) rebar every 15 cm (6 inches) as crack reinforcement, arranged in a cross pattern with a distance of 5 cm (2 inches) from the top and bottom. The reinforcement should run in 4 bearing pockets that measure 20 cm by 20 cm (8 inches by 8 inches) and are 10 cm (4 inches) deep.
Your option with the steel beams probably works as well.
Note the irony: Should I draw another plan?

Thank you for your reply. Yes, it is a DIY project. I have completely renovated an entire house as a DIY, just like the pool that is currently under construction. So far, I haven’t hired any tradespeople and have been able to do everything myself.
You just need to know which materials to use and, if necessary, how the structure should be built, then there’s no need to hire a company for that.
Your theoretical explanation is good. If it really requires that “little” steel, that’s great. I thought beams would be needed because of the load from above, but the less steel needed, the better. Thank you very much.
I would also be happy to receive a plan as well.
