About this detail

Utility trench excavation, pipe bedding, and backfill configurations for both paved and unpaved areas. The trench features a drain pipe set on prepared bedding with a tracer wire or warning tape installed six inches above the pipe. Backfill consists of crushed stone, gravel, or compacted native soil, with five-sack slurry cement required in pavement areas having less than one foot of cover to subgrade. A valve box with a cast iron top and cover terminates at the finish grade with a concrete or paver collar.
