Key Interpretations:
Cross-section: Diagonal measurements indicate square cross-sections:
Top width = 600/√2 ≈ 424.3 mm
Base width = 980/√2 ≈ 693.0 mm
Flange Plate:
"11006.0" interpreted as 1100 mm diameter × 60 mm thickness (consistent with previous drawings)
Bolt pattern "18-945" indicates 18 bolts on 945 mm Pitch Circle Diameter
Anchor Bolts:
18 × M36 anchor bolts
1750 mm length specified
Material:
Q235 steel (equivalent to ASTM A36, yield strength 235 MPa)
Hot-dip galvanizing likely required (though not explicitly stated)
Unspecified Parameters:
Foundation depth and concrete specifications
Coating/surface treatment details
Electrical/grounding system
Rebar cage details
Connection method between tower sections
