Proposed HDD Road Crossing Profile with 180 mm HDPE Pipeline Design

This detailed horizontal directional drilling road-crossing drawing provides a complete engineering layout for installing a 180 mm HDPE pipeline across a roadway. The plan view clearly displays the entry and exit points, tie-in alignment, and total crossing length measured at 288.10 m. The cross-sectional profile illustrates the 10° entry and exit angles, the 250 m radius of curvature, and a maximum depth of 8.94 m, offering accurate guidance for underground trenchless installation.

The drawing includes a sectional diagram of the HDPE pipe surrounded by bentonite slurry and a 12-inch reaming diameter required for bundle pulling. All dimensions are specified in meters to support precise on-site execution. Additional construction notes highlight the placement of survey coordinates, ground levels, and the exact drilling path required to maintain safe clearances throughout the road crossing. This layout ensures reliable pipeline installation while minimizing surface disruption, making it highly useful for civil engineers, contractors, and infrastructure design professionals involved in HDD-based utility works.
