Reference for pipeline backfill compaction specifically what compaction vehicle to use/not use

Reference for pipeline backfill compaction specifically what compaction vehicle to use/not use

Reference for pipeline backfill compaction specifically what compaction vehicle to use/not use

(OP)
Can someone link me to a good reference regarding pipeline backfill compaction. I'm researching if those heavy compaction vibrating drum roller normally used for soil compaction are not allowed if they can damage u/g pipe.

(OP)
There a lot of reference how to check pipeline against vehicle loads but I have a hard time finding reference against compaction vehicles used during backfill.

RE: Reference for pipeline backfill compaction specifically what compaction vehicle to use/not use

You obviously do not want heavy vibrating drum rollers near an underground pipe. If nothing else, you run the risk of at least vibrating any sharp rock that happened to make its way to laying next to the pipe and possibly damaging the coating.

Normally it is not necessary to compact covering soil to such an extent that cannot be accomplished by gravity alone in a short period of time. Excessive soil excavated from the ditch and not required to fill the trench should be removed from the site.

Areas above the pipeline requiring good compaction are normally limited to very short distances of pipeline inside plants, under parking lots, or at open cut road crossings, etc. As such it should be more than possible to use conventional smaller compaction tools, i.e. one-man opeated vibration compactors, but nothing mounted on heavy equipment.

useful info can be found in "buried pipe design" - 3rd edition - Moser/Folkman - chapter 3 - compacting techniques

Define "heavy"....

I've seen remote control vibrating roller machines in the trench before, but not the large rolling machines you might see on a road system.

But one metre below ground I would have no issues with a big vibrating roller going over a pipeline.

High yield strength steel pipelines can take an awful lot of punishment before anything goes wrong....

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

pipe zone material should not be compacted with large equipment. once you get about a foot or two above the pipe, than larger equipment could be used

RE: Reference for pipeline backfill compaction specifically what compaction vehicle to use/not use


I suspect the subject is compaction of final backfill with excavated material rather than padding and pipe zone backfill..

The typical compaction equipments are, Pneumatic tampers, vibratory pads ,pneumatic tampers , and trench
compactors ...

The use of heavy mechanical equipment such as sheepsfoot rollers, dozer etc shall be carefully studied ..

I will suggest you to look the following doc. ( Onshore Pipelines Road to Success IPLOCA doc.)
The item 6.2.2.8.10 Compaction . A good start for young engineers..

Never seen it happen. Thank God for that. It would not have been a good day for that guy, I guar-ran-tee!
