Question:

Glass fiber reinforced plastic sand pipe backfill 5m, how much kg pressure?

Glass fiber reinforced plastic sand pipe backfill 5m, how much kg pressure?

Answer:

These two parameters are based on the need and the actual geological situation to determine, not a backfill a few meters can be determined.
In general, glass steel pressure refers to the internal pressure, the conveying pressure of water, and you said the backfill produces is the external pressure, often say that the stiffness parameter.
You don't even know the pressure inside.
