Key Interpretations:
Cross-section: "Top Cross-section (Diagonal) 380mm/Bottom Cross-section (Diagonal)600mm" indicates diagonal measurements of a square cross-section. Corresponding side lengths:Top width: 380/√2 ≈ 268.7 mm
Base width: 600/√2 ≈ 424.3 mm
Bolt Configuration:
12 × Ø38 slotted holes provided
8 × M32 anchor bolts installed (1700 mm length)
Foundation:
2500×2500 mm concrete base with 200 mm thickness
Anchor cage and rebar cage integrated as single unit
100 mm exposed above ground level
Electrical:
Ø89 mm conduit buried at 0.5 m depth
50×5 mm galvanized flat iron grounding electrode driven 1 m deep
Flange Plate: "900*5.0" interpreted as 900 mm diameter × 50 mm thickness (consistent with previous drawing convention)
