Trench walls in poor soil conditions may need to be excavated in steps, or be battered, to prevent collapse of the trench wall materials. For eankment installations, a sub trench may be excavated once the eankment has been partly built up, in order to help protect the PE pipes from construction vehicles, and also lessen the external loads acting on the pipe.
Trench Widths In general practice, the trench width should be kept to the minimum that enables construction to readily proceed. Refer to Figures 4.6 and 4.7. The trench width used with PE pipe may be reduced from those used
/05/31 Customers normally advise that trench bottoms should be excavated to provide a reasonably even bed along the pipe length and free of sharp stones or other objects that could damage the pipe. Sand for pipe bedding
