A minimumof 12 inches depth of cover is recommended for diameters 48 inchesand smaller and a minimum of 24 inches for 60 inches diameter pipe.For more information on minimum and maximum burial depths and deflection,see Table 14 on page 57.2.5 Preparation of Trench BottomThe trench bottom should be smooth and free from stones greater than1.5 inches in diameter, large dirt clods and any frozen material. Excavationshould be provided so that the pipe is uniformly supported along its length.For details regarding the foundation for the trench bottom, pipe bedding andinitial backfill around the pipe, see Section 4 of the manual.16 EAGLE CORR PE INSTALLATION GUIDE
2.6 Trench Safety, Trench Boxes and SheetingTrenches can be dangerous and the contractor has the responsibility of ensuringthat all safety regulations and design requirements have been observedfor the protection of the workers and the public. OSHA requirementsshould always be followed when using a trench box.The length of the trench box should be suitable for the pipe length. The mosteffective trench configuration is the subtrench method as shown in Figure 6.This subtrench method is effective in maintaining the integrity of the backfilland compaction, while meeting safety requirements. The maximum recommendedsubtrench is 24 inches, as shown in Figure 6. Backfill and compactwithin the subtrench should be in accordance with the design specifications.The trench box can be pulled along the top of the subtrench without affectingthe pipe or the backfill.Trench box6" min.TrenchcenterlineNativeIN-SITU SoilInitial backfillmaterial placedand compactedper projectspecifications2"—0" subtrenchAlternateexcavationlineGeotextile(if necessary)Trench widthper project specificationFigure 6EAGLE CORR PE INSTALLATION GUIDE17
