| 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. | |||
