Trench Section CAD Drawing with 1600mm Pipe and Earth Filling Detail

This Trench Section CAD Drawing illustrates a detailed underground utility trench design with a 1600 mm diameter pipe installation. The drawing is prepared at a standard engineering scale and includes a clear representation of ground level, earth filling, sand filling, and pebble filling layers. It shows proper trench slope, pipe bedding arrangement, and backfilling method for safe and durable pipeline construction. All structural elements, material zones, and filling depths are accurately marked, making this DWG file suitable for drainage, sewerage, and water pipeline projects.

The drawing also highlights sectional dimensions, soil layers, and compaction zones required for infrastructure and civil engineering works. It is useful for architects, civil engineers, contractors, and site planners involved in underground utility and road development projects.
