ᐅ Pressurized water penetrates the reinforced concrete wall into the basement.

FürstHello, I’m new to the forum and hope this is the right place to ask. I have the following problem. There is an old air-raid shelter beneath my basement, and unfortunately, I’m experiencing a troublesome moisture issue in this space. It is a reinforced concrete structure with walls that are 1.50 meters thick (5 feet). Two old pipes (3/4 inch) lead into the room from outside. Inside the room, they are open-ended because they are no longer in use. Outside, they go into the ground. A blind flange is screwed on the inside.
The problem is that groundwater pressure from higher up on the hill is building up and pushing against this reinforced concrete wall. Water is entering at the point where the old pipes penetrate the wall. How should I proceed? Completely breaking open and re-filling the area is unfortunately too complicated. Would it be possible to cut off the old pipes entirely and then cast another concrete block on the inside, creating a double wall? Would this help, or would water still penetrate through the new concrete at that spot?
I would be very grateful for any technical advice.
