Can HDPE pipe crack?Can HDPE pipe crack?Tests at Utah State University show that heavy soil loads will fracture the wall of rigid pipe, but under identical conditions, will produce only moderate deflection in flexible polyethylene pipe . HDPE will not crack or break during proper installation, and maintains its impact strength at sub-zero temperatures . ADDITIONAL INFORMATION AVAILABLEHDPE Drainage Products How far should a pipe backfill be extended?How far should a pipe backfill be extended?Structural backfill material should extend six inches (0.15m) over the crown of the pipe; the remaining cover should be appropriate for the installation and as specified by the design engineer.

What is backfill load?What is backfill load?The backfill load is normally well distributed over the top of the pipe. However, proper pipe support must be constructed on the bottom of the pipe to distribute the load. Proper soil support under the bottom of the pipe is also necessary to maintain grade (elevation) of the pipe.Pipe Bedding and Backfill1.02A Single Wall HDPE Pipe - Advanced Drainage

Backfill can also be done using flowable fill, a cementitious material with a low water-cement ratio that is delivered to the job site by a ready-mix truck. Typically, the utility pipe or other equipment in the trench is first covered with an aggregate material, then the flowable fill is placed in the trench directly from the truck, just like regular concrete.

Pipe Bedding Factor - CivilWeb Spreadsheets

> Drainage Design Spreadsheets drainage pipe backfill traders bedding type is used when a high supporting strength is required or where it is desirable to avoid importing selected backfill over the top of the pipe. The higher pipe bedding factor achieved by class S bedding is dependent on the compaction of the side fill. For this reason the supervision and control of the drainage pipe backfill tradersPipe Bedding and BackfillRigid pipe is designed to transmit the backfill load on the pipe through the pipe walls to the foundation beneath the pipe. The pipe walls must be strong enough to carry this load. A line load at the top and bottom of a pipe is the worst possible loading case. If the load can be distributed over a large area at the top and at the bottom of thePipe Bedding and Backfillresists the deflection of the pipe due to load.
