610.4CONSTRUCTION
1 Install metal drain inlets in the completed embankment slope at specified locations or as
staked by the engineer. Do not order pipe before the engineer checks pipe lengths and elbow angles in the field. Use pipe of any material specified above. Use metal inlet units. 2 Excavate
a trench in the embankment slope of sufficient width for pipe and fixture installation. Install the metal drain inlet, elbows, drain pipe, and metal drain outlet and connect with coupling bands to provide a complete drainage unit. Make joints watertight by installing flat rubber gaskets at each joint.
After installing metal drain inlet, backfill the trench to the original slope line in accordance with Subsection 206.4.5, Backfilling. Compact backfill material to at least the density of the adjacent embankment.
