This is what happens when there is no waterproofing

Haha, wonderful

Haha, you kept us in suspense for a while

Yes, it's always fun to read all the speculations . However, there wasn't much of that here

I didn't feel like digging out about 1 cubic of soaking wet clay in pitch darkness and rain by hand last night to then cut a pressurized 110 pipe where water would gush out, and then try to put on a coupling and plug in the slurry....

That will have to wait until it dries up a bit and the water has drained from the pipes

Sounds like it's quite wet in the ground where you live.

I wonder if it might be worth digging a properly deep pump pit (about 1-2 meters) and continuously pumping out water from there and dumping it as far from the property as possible, or alternatively into the sewage system. Admittedly, it's just a relocation of water that then flows back, but at least it should form an inverted cone of reasonably dry ground under the house.

You should have worded yourself differently to maximize speculations, "Help, water is gushing out of the floor" or something similar, along with pictures that look like they were taken in panic and with wet rags everywhere

I'm glad I live on a gravel ridge, with the groundwater level about 2-3 meters below the basement floor

The house was built in '47 and there is probably at least 10 meters of blue clay down to the bedrock, if not more. I think it could be a bit risky to change the conditions. After all, it has stood in the same place without settling problems for 70 years now...
It's also not a problem for the basement to get damp, as long as water doesn't run in (or up).

Additionally, there is a proper ditch 2 meters from the house wall that always has water in it, so I doubt such a pump pit would do anything other than cost money
