loosely placed to provide uniform support at the invert. Acceptable beddingmaterials include Class I, II, or III materials as defined in Table 6.If the native in-situ soil is comprised of fine grain soils and migration of thosesoils into the bedding material is anticipated, precautions should be takento eliminate or reduce the potential for soil migration. Acceptable methodsto minimize the potential for soil migration include, but are not limited to,nonwoven geotextile layer, use of acceptable bedding material with fines thatfill potential migration sites or other acceptable method to avoid compromisingthe trench backfill materials as specified by the engineer.Bell holes are used to maintain the grade of the pipe in cases where the pipefitting or coupler is greater than the outside diameter of the pipe. Properlyformed bell holes should not be over excavated and should provide uniformlongitudinal support for the pipe.4.6 Initial BackfillInitial backfill is critical since it provides support to the pipe to resist soil and liveloads. Initial backfill begins from the bottom of the pipe to a level of 6 inchesabove the top of the pipe. This material and minimum required compactionlevel should be on the construction plans and will take precedence on theproject site. Provided the plans meet minimum recommendations, backfillingshould follow trench excavation pipe assembly as closely and safely aspossible. Backfilling after pipe assembly eliminates the possibility of liftingthe pipe from grade due to flooding of an open trench, avoids shifting pipeout of line by cave-ins, and in cold weather lessens the possibility of backfillmaterial's becoming frozen.Placement of the initial backfill is a critical part of the installation operation.Typically, backfill material is placed in the center of the pipe allowing materialto fall on each of the pipes to keep soil pressure evenly distributed. Evendistribution of soil pressure during the initial backfill operation keeps thepipe aligned in the trench. In-situ or local material may be acceptable forbackfill, however, it is necessary that locally available material meet the soilclassifications outlined in Table 6. Minimum compaction levels, lift depthsand backfill material quality requirements are shown in Table 6 as well.38 EAGLE CORR PE INSTALLATION GUIDE
