Settlement of backfill material
Settlement of backfill material
(OP)
Lift station installed on berm of pound. Berm is 10 mt height form adjoining ground. We installed steel discharge pipe up to 6 mt form lift station wall. And it has two robar coupling, one at the wall and other at transition form steel to DR18 pipe.
Engineer concern about chances of settlement of ground will damage piping system. Because depth of back fill is 10 mt and material is clay. I try Googled to find out relation between time and settlement of backfilled material over the time in the give loading conditions. But no luck.
Thanks in advance for information sharing and suggestion.

What size of force main?
What is the composition of the backfill, is it all excavated material?

The typical practice is to compact the backfill as it is placed. If the compaction was skipped, there may be settlement problems with 10 meters of fill.
RE: Settlement of backfill material
it will be compacted well after we pipe installtion but not sure about how much good during the bank construction.
Is there any how pipe can be protected in event of settlement. I think pipe support would make situation worst.
Thanks for your reply,
