AutoCAD Electrical Tunnel Section T2 Detail With Insert Plate Levels

This AutoCAD drawing presents the Section T2–T2 typical detail of an electrical tunnel, clearly drafted for construction and service coordination purposes. The section illustrates a tunnel width of 1350 mm with 250 mm side offsets on both sides, maintaining precise internal clearances for safe movement and equipment access. The drawing includes floor and level references from ±0.00 at the top to ?2.05 at the bottom, helping engineers understand depth and elevation control. A 100 mm thick PCC base is shown as typical, along with 150 mm thick metal soling below, ensuring proper load distribution and durability of the tunnel foundation.

The electrical tunnel section further details vertical insert plates sized 150 × 175 × 10 mm thick, placed at 1000 mm center-to-center spacing, with the bottom level fixed at ?2.00. These inserts are accurately positioned for mounting electrical supports and services along the tunnel wall. Typical wall thicknesses of 100 mm and 150 mm are clearly marked, supporting structural clarity during execution. This AutoCAD DWG file is ideal for civil engineers, electrical consultants, architects, and contractors working on infrastructure and utility projects.
