Bridge Reinforcement Construction Sequence Diagram HBHC-3

A comprehensive bridge reinforcement procedure diagram showing a phased approach for structural rehabilitation. The drawing illustrates a two-stage construction process: Phase 1 focuses on beam replacement, and Phase 2 covers bridge deck construction.

Key Construction Phases:

Phase 1: Beam Replacement

– Removal of existing bridge deck
– Safety measures for traffic control
– Removal of deteriorated main beams
– Installation of new main beams

Phase 2: Bridge Deck Construction

– Installation of formwork for new deck
– Placement of reinforcement and concrete
– Curing of bridge deck structure
– Finishing work and traffic restoration

The diagram includes both schematic illustrations and detailed construction steps for each phase, providing engineers with clear visual guidance for implementation. The sequential approach ensures structural integrity is maintained throughout the rehabilitation process while minimizing traffic disruption.
