| Handling &
Construction |
 |
| All pipe should be lifted off the trailer
to avoid any damage while unloading. Never allow pipe
to be dragged off or dropped from trailer height. Slings
should be used for lifting the pipe off the trailer and
for positioning pipes in the trench. |
| When unloading a nested pipe shipment,
make sure that the delivery site has ample room for un-nesting
the various pipe sizes. Special care should be taken
to avoid damaging pipe while un-nesting pipe. Un-nest
a pipe by using a two-by-four that is one to two inches
larger than the pipe’s inside diameter. Wedge it
into corrugation valleys and then pull on two-by-four
with a chain or wire rope |
| Use caution when handling pipe. Pipe ends
may be sharp. Handle with care. Use gloves and other
proper protective clothing and equipment. Stack the pipe
on the trailer or ground with proper blocking or strapping.
Be careful when removing binders or strapping on pipe
bundles, either on the trailer or ground. Never stand
on pipe bundles. |
| Use well-graded compacted granular bedding
or flowable fill material to one foot above the pipe.
Trench backfill should be free of rocks, frozen lumps,
and foreign materials that could cause hard spots or
decompose to create voids. |
| Contact Pacific Corrugated for detailed
specifications regarding backfill methods and materials.
ASTM Specification A798 - “Standard practice for
installing factory made corrugated steel pipe for sewers
and other applications” is a recommended reference. |
