Bailey bridge pier serve as the support structures that hold up the bridge deck and transfer the weight of the bridge and any loads crossing it down to the ground or riverbed below.
Trestle Legs:
The vertical legs that rest on the ground or riverbed and support the weight of the bridge. Typically made of steel or aluminum for strength and lightweight. Come in various lengths to accommodate different gap/river depths.
Chesses:
Wooden or steel planks that form the deck surface of the bridge. Laid perpendicular across the transom beams. Provide a solid, traversable surface for vehicles and pedestrians.
Sway Bracing:
Diagonal bracing members that connect the trestle legs. Can be made of steel rods or cables.
Provide lateral stability and prevent the pier from collapsing sideways.
Key features of Bailey bridge pier
These features combined make the Bailey bridge pier design highly adaptable, versatile, and well-suited for temporary crossings in challenging environments. The portability and speed of assembly were critical factors in the widespread use of Bailey bridges during WWII and other conflicts.
Lightweight Materials:
The trestle legs are typically made of lightweight yet strong materials like steel or aluminum.
This reduces the overall weight of the bridge, making it easier to transport and assemble.
Rapid Assembly:
The modular design allows the piers to be quickly erected without specialized tools or equipment.
Standardized Components:
The piers use a limited number of standardized parts.
This simplifies maintenance, repair, and replacement in the field.
