HD321 type Bailey bridge pier (hereinafter referred to as "Bailey pier") is developed to solve the above problems. By setting one or more piers in the middle of the bridge, the simple supported beams become continuous beams, thus greatly improving the adaptability of the bridge to the erected span.
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 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.
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.
The piers of a bailey bridge 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. The piers are typically made up of the following main components:
Trestle Legs: The vertical legs that rest on the ground or riverbed and support the weight of the bridge. These legs are usually made of steel or aluminum.
Transom Beams: Horizontal beams that span between the trestle legs, creating a support frame.
Sway Bracing: Diagonal bracing members that connect the trestle legs to provide lateral stability.
Base Plates: Steel plates that distribute the weight of the trestle legs over a larger area at the base, preventing excessive sinking into soft ground.
The height and number of trestle legs used depends on the depth of the gap or river the bailey bridge needs to span. Additional intermediate pier supports may be added for longer bridge spans. The entire pier structure is designed to be modular and easily assembled on-site using standard parts.
The key advantage of bailey bridge piers is their portability and rapid deployment, allowing bridges to be quickly built and then dismantled when no longer needed. This made them invaluable for military applications and disaster recovery efforts.
The piers of a Bailey bridge are the critical support structures that hold up the bridge deck and transfer the loads to the ground or riverbed below. The main components of a Bailey bridge pier include:
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
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
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
Crucial for stability on unstable or marshy terrain
The modular design of Bailey bridge piers allows the height and number of trestle legs to be adjusted as needed to accommodate different gap widths and depths. Additional intermediate piers can also be added for longer bridge spans.
The key advantages of Bailey bridge piers are their rapid deployment, easy assembly, and adaptability to various terrain and crossing requirements. This made them invaluable for military and disaster relief applications.
key features of the piers used in a Bailey bridge design:
Modular and Portable Design:
The piers are made up of standardized, pre-fabricated components
These components can be rapidly assembled and disassembled on-site
This allows the bridge to be quickly deployed and then removed when no longer needed
Adjustable Height:
The number and length of the trestle legs can be varied to accommodate different gap depths
This flexibility allows Bailey bridges to span a wide range of obstacles
Lateral Stability:
The diagonal sway bracing members provide strong lateral support to the piers
This prevents the piers from collapsing sideways under load
Load Distribution:
The transom beams distribute the weight across multiple trestle legs
The large base plates at the bottom of the legs spread the load over a wider area
This helps prevent excessive sinking into soft ground or riverbeds
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
Rapid Assembly:
The modular design allows the piers to be quickly erected without specialized tools or equipment
This enables rapid deployment of the Bailey bridge in emergency or military situations
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.
