Tank Ring Walls
Tank Ring Walls
(OP)
I have read a few threads about ring walls and have a different question.
First off, I am not an engineer. I work at a small power plant and we have a 26' x 26' water storage tank that sit atop a 4' ring wall. I noticed water leaking around one side of the base of tank. The ringwall was damaged slightly during the 6.5 San Simeon Earthquake back in 2004.
We filled the cracks in the foundation with an epoxy. The epoxy has since cracked. I have noticed that the concrete under this section of the tank is about 10 degrees hotter than the rest of the ring. Is this significant?
I believe the ring is 2' wide and has anchors to conform with Seismic zone 4.
We plan on going into the tank in May to inspect the floor. Is there anything else I should be concerned with? Is it possible that the leaking water is permeating into the concrete causing it to be hotter at that point?
Thanks for any replies.

RE: Tank Ring Walls
You said the tank is 26' x 26'. Is it round or square?
What's in the tank? Is it plain water, cooling water, potable water, etc?
As far as the concrete around the damaged area being warmer, that's a real stumper. There's no reason that repaired concrete should be creating heat. If the liquid is warm inside, it might be closer to the exterior due to the cracks and locally warming it.

The water is 180 degree "boiler feed" water.
Inside the ring is 95% compacted oil sand.

From my previous life in the power plant business, I remember a lot of jerry rigged systems held together with baling wire and chewing gum.

Thanks for all your input Jed. I'll come back in and post later once we figure out where we want to go with it.
