About this file
This technical drawing is a detailed schematic for "Trenches for Conduit and Direct Burial Cables" dated August 2016. The diagram illustrates five different trench configurations (UT1-UT5) for underground cable installation, showing cross-sectional views with varying layers of backfill materials including sand/gravel/clean soil, compacted backfill, and concrete encasement. The drawing provides specific technical specifications for trench construction, including key notes about cable installation, trench depth and width, and safety requirements.
The legend and notes outline critical installation guidelines, such as maintaining 12-inch minimum clearance between power and communication cables, following National Electrical Safety Code standards, and specifying different trench types: standard trench, trench with concrete encasement, trench with concrete cap, directional bore, and plow. The diagram distinguishes between different backfill materials using distinct hatching patterns, with designated areas for sand/gravel, compacted backfill, undisturbed earth, and concrete, providing a comprehensive visual guide for underground cable infrastructure deployment.
