Introduction of Bailey Bridge Pier
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.
Bailey bridge pier is composed of foundation, pier body, top support and bridge span
fixing device. The foundation consists of a base plate and anchor
bolts; The pier is composed of 1m truss, Angle brace, HD321 Bailey
panel standard truss, vertical cross brace 1, vertical Raker,
vertical cross brace 2, horizontal wind structure.
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.
Provide lateral stability and prevent the pier from collapsing
sideways.
Can be made of steel rods or cables.
Transom Beams:
Horizontal beams that span between the trestle legs, creating a
support frame.
Help distribute the weight across multiple trestle legs.
Can be made of wood, steel, or aluminum.
Key features of Bailey bridge pier
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.
The pier of HD321 Bailey pier adopts 1m truss and HD321 Bailey panel standard truss as the
foundation components to form square column pier. The top support
of the pier is composed of beam staggered connection, and the space
bar structure is connected between the pier. Adopting such a
structural form is easy to meet the scale requirements of the
structure, improve the adaptability of the pier structure, and give
full play to the strength of materials. Increase structural
stability.
