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. 

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.

Base Plates:

Steel plates at the bottom of each trestle leg.

Distribute the weight over a larger area to prevent excessive sinking into soft ground.

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.

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. 

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.

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

Standardized Components:

The piers use a limited number of standardized parts

This simplifies maintenance, repair, and replacement in the field

The top support is composed of connecting plate 1, connecting plate 2, top beam air structure, top beam 2 tie rod, top beam 2 air structure, lower top beam 1, lower top beam 2, upper top beam and cushion beam; The bridge span fixing device consists of a press rod and a press rod seat.

1m truss and 321 Bailey panel standard truss can be assembled and erected according to the height requirements of the pier. The weight of the pier rod is light, the maximum unit weight is about 270kg, the maximum length is 3.334m, and it can be transported by ordinary road or railway vehicles, with large loading coefficient and convenient storage and transportation.
