Water filled silo
Water filled silo
(OP)
What is the most common method of rendering water filled silos watertightwith with respect to:
a) New water filled silos (about 30 m high): Is a liner used to render it water-tight, or is it to design to limit crack width and not use a liner, or is some other method used?
b) Existing 70 or 80 year old silo (about 30 m high) that was used for storing granular materials but now they want to convert it to store water. Would a steel liner be used to keep the water from leaking out through the cracks? Or would external prestressing be used and no liner? Or would a reinofrced concrete liner be used? Anyone with experience with this who can answer this? Thanks.

RE: Water filled silo
For silo design in general, the loading is a combination of internal pressure and downward frictional forces. The internal pressure used for design may be less than what will be developed with water. It would depend on the product for which the silo was designed, and the amount of conservatism built into it.
You may have similar issues with the foundation if the design product was lighter than water.

b) This sounds pretty crazy. Unless you have good record drawings of the silo, you might end up with a catastrophic failure. Water storage tanks cost about 40 to 90 cents a gallon to construct. By the time you modify a granular material silo, you'll pay a lot more.

Just don't use heavy water and you'll be fine. :)
