    Creep Earth
AI Thread Summary
When installing an above ground pool on a sloped area, concerns arise about earth berm creep potentially impacting the pool's stability. The water pressure from the pool may not counteract the downhill movement of the berm, leading to possible structural issues. Recommended solutions include building a fence with lumber and filling it with dry quickcrete for reinforcement, or regularly digging out the berm, though the latter is seen as unnecessary. Using coarse gravel between the soil and the pool wall can help manage drainage and reduce hydraulic pressure. Addressing the berm issue is crucial to prevent potential collapse, as neglecting it could lead to significant problems over time.

I'm helping to install an above ground pool. We leveled the ground. This left a 22" berm on the high side. We left an extra foot of space between the berm and the pool edge, but we're concerned it's going to eventually creep down hill and put pressure on the side of the pool.

How big of an issue is this? Will the water pressure counter the creep, or will the hill push into the side of the pool? What is a cheap way to handle this? (It's a $200 kiddie pool, 48" deep. It's not worth spending thousands of dollars.)

The soil is loam and clay with a few 4" size stones. It's on a naturally level spot on the side of a mountain in WV.

The current front runner solutions are:
  • To dig it out every year or two.
  • Build a fence using 4X4s and 5/8ths lumber, then fill the backside with dry quickcrete.
  • Ignore the problem.

Hey,
Definitely don't ignore the problem because one of my old neighbors had a problem similar to this but left it only to realize some time later that a wall had collapsed from the pressure. Digging it out every year or two would work but its unnecessary. I'd say build the fence with the lumber and use the quickcrete. it can be done fast and is fairly cheap but to be honest if its an above ground pool they are usually made to stay but can move over time so using just lumber by it self could be a good reinforcement

If you pack the volume between the soil and the pool wall with a coarse gravel it will be able to drain water and so not present a large hydraulic pressure against the pool wall. Dry gravel does not flow like a soil that contains some clay.

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
