Mountainous Area Installation Guidelines
Terrain and Foundation Preparation
- Foundation Stability: Ensure solid soil conditions at bridge seat locations. Reinforce foundations where bearing pressure is insufficient.
- Repose Angle Pile Setting: Calculate and position repose angle piles according to slope conditions exceeding repose angle.
- Site Requirements: Assembly site length should be ≥1.5 times bridge span with 8-14m width. Maximum 3% longitudinal slope with approximately horizontal level.
Erection and Construction Safety
- Bridge Span Push: Maintain bridge center of gravity behind push-pull shore rock using guide beams to prevent overturning.
- Roller Setting: Position rollers at marked locations with sample plates. Maintain 1.0m distance (minimum 0.75m) between rock and support plate.
- Worker Safety: Mandatory safety helmets and harnesses. No alcohol consumption during work. Designated crane operators for Bailey pier operations.
Bridge Stability and Reinforcement
- Wind-Resistant Components: Install diagonal braces on odd-numbered beams and wind-resistant tie rods on even-numbered beams for spans 30m.
- Multi-Row Truss Reinforcement: Install support frames and connecting plates to enhance structural stability.
Additional Installation Notes
- Bridgehead Slats: Connect bridge to access road using bridgehead slats with side buckle slats and fixed flanges.
- Bridge Deck System: Option for full assembly before pushing or partial installation post-positioning. Secure longitudinal beam ends into crossbeam clips.
