Gravel Bedding for 900mm Diameter Steel Pipe
(OP)
Hi to all,
I would like to ask if one can use gravel as bedding for a 900mm diameter steel pipe. If yes, what will be the size limit for the gravel to be used? Can you guys site any reference standards or documents to prove this usage? Thank you for those who can answer.

"For many installations, gravel or dry coarse sand falls into place at adequate density without additional compaction."

"Trench Breaker ‐ Trench breakers (also known as trench plugs) are barriers placed within an open
pipeline excavation in order to slow flow and reduce erosion in the trench and also to prevent the trench from becoming a subsurface drainage path."

without further information, hard to tell what kind of pipeline you are building

Also depends on the amount of gravel and if the pipe moves in any way. Pea gravel moves under pressure and can allow the pipe to float through it. Sometimes you want some flexibility - most times you don't....
