Bridges and tunnels represent construction's most demanding environments. Massive concrete volumes, unstable waterlogged foundations, traffic flow constraints, and extreme heights require engineered scaffolding solutions beyond standard building work.
Scaffolding Hub supplies bridge-rated cuplock and tunnel formwork systems. Call Sahil Bansal at 7678601694 for infrastructure-grade rentals.
Bridge Construction Scaffolding Applications
1. Pier & Abutment Formwork
Load: 75kN/leg minimum
System: Cuplock + heavy props
Height: 10-40m above water/traffic
Challenge: Deep foundations, river currents, crane access.
2. Deck Falsework
Span: 5-15m clear spans
System: H-frame + steel centering plates
Load: 25kN/sqm wet concrete
Challenge: Traffic below, wind loading, precise alignment.
3. Parapet & Railings
System: Mobile cantilever towers
Height: 2-4m above deck
Advantage: Quick repositioning between segments
Tunnel Construction Scaffolding
1. Segmental Lining Formwork
System: Hydraulic travelers
Cycle: Pour → cure → advance (24hr)
Load: 50kN/sqm lining pressure
2. Access Scaffolding
System: Ringlock (curved tunnel walls)
Height: Full tunnel diameter
Advantage: 360° access around circumference
3. Ventilation/Maintenance
System: Suspended platforms
Advantage: No tunnel floor obstruction
Engineering Requirements
Load Calculations:
Wet Concrete Pressure: 20kN/sqm
Live Load Workers: 4kN/sqm
Environmental: Wind 1.2kN/sqm
**Design Factor: 1.6 safety margin**
Critical Features:
-
Water-resistant couplers
-
Corrosion protection (galvanized)
-
Vibration resistance (heavy pours)
-
Traffic-rated base systems
Cost Example: 100m Flyover Segment
Pier Scaffolding: 250 cuplock bays × ₹85 = ₹2.13L/month
Deck Falsework: 40 H-frames × ₹95 = ₹3.8L/month
Parapet Mobile: 8 towers × ₹75 = ₹0.6L/month
**Total: ₹6.53L/month**
Rental advantages: Scale to match segment progress.
