itsbob said:How about the shallpw end of the pool is 3 feet with a equal slope to the deep end of the pool to 9 feet. giving us (3*25*30)+.5(6*25*30)= 4500ft^3
4500ft^3 * 7.48 = 33660 gallons * 8.3 lbs per gallon = 279,378lbs
OR 4500^3/27 = 166 yards^3
166 * 2700 lbs per yard for gravel = 448,200 pounds or 224 tons
Howzat?

wanna come estimate for me?
but as far as the weight goes, your 2700 lbs per yard is for regular gravel, I was guessing at the 3000 lbs for the pea gravel because it seems (a guess on my part) to be a higher density than regular gravel.
I suppose I could actually look it up in one of my books and get an exact weight, but your weight and my guess are close enough to assume that actual weight might be somewhere between the two.
still, way too much weight to be setting on the bottom of a swimming pool.
oh and while Im at it, pools almost always have a three foot section that will run constant for a number of feet, then the constant slope down to the deep end with a level run at the final depth for an equal number of feet, so the actual slope would not take up the whole lenght of the pool, but more like 2/3 of the length.
Im sure if we search we could find a maximum allowed slope for the pool and come up with a very close guess to the real run of the angle.
but honestly, who really cares enough to do that?
Somehow this creeped by me, post of the day yesterday...Wenchy said:Sleuth, is that you?
bcp said:chances are that the pool is in need of major repair now.
thats a bit more than two tons of gravel dumped in there.
to fill that pool you have somewhere around 250 yards of gravel
the weight of a yard of gravel is almost 3000 lbs by itself so you have somewhere around 750,000 lbs of pea gravel in that pool (assuming that the 9 ft deep is constant.)
now when you take the weight of what the pool should have in it
and that pool would be about 50483 gallons at 8.3lbs per gallon or 419096lbs of water, you can see that the pool is holding a bit more weight that designed for. with just the gravel alone.
now, if they did not break out the bottom of the pool for drainage when it rained, then we also have the added weight of water that builds up at the bottom.
considering also that water flows down and out when its in a container, the corners at the bottom are where the most pressure is created when the pool is filled with water. The stone on the other hand is putting the direct pressure on the bottom surface of the pool, and it will most likely not hold that weight very well.
so, even if you empty the pool of all the gravel, be ready to have the pool repaired and a liner installed before you can actually fill it with water and use it again.
