This enhances contact between pipe and soil and mobilizes the passive resistance of the soil. This resistance aids in preventing further pipe deformation and contributes to the support for the vertical loads.

Inspection Manual For Pipe - IN.govThere are several different types of pipe nd treatments being used. e The Technician is required to know which type is required for each structure because some end treatments affect the length of pipe necessary for construction. The standard drawings indicate details for each type of end treatment. The end treatments used are as follows:

For embankment installations, a sub trench may be excavated once the embankment 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.

Trenching - HDPE PE pipe (polyethylene pipe)

No special trenching requirements are normally needed for PE compared to other materials and the preparation of trenches should follow national or local practices. Sharp stones should be removed from the base of the trench and where laying the pipe across rock or granular soil of angular consistency, such as gravel or cobbles, the trench should be excavated below the required depth to allow the pipe to be ePipe HDPE Pipe Design and Constructionthe pipe and trench box wall was too narrow to allow proper com-paction. Further, dragging the trench box loosened the backfill around the pipe.3 The Contractor did not comply with the specification requirements for dewatering beneath the pipe trench, which led to difficulty achieving proper compaction of pipe embedment.3hdpe pipe trench detail in moroccohdpe pipe manufacturerwhere to buy hdpe pipehdpe pipe specificationsSome results are removed in response to a notice of local law requirement.
