Portable Steel Truss Bridge Galvanized Construct A Bailey Bridge

Portable Bailey Bridge/construct A Bailey Bridge

The Type 200 Bailey Bridge is particularly suitable for the following special scenarios due to its unique design and performance characteristics:

1. **Long-span bridge requirements**
The truss height of the Type 200 Bailey Bridge has been increased to 2.134 meters, and its load-bearing capacity and stiffness have been significantly improved compared to the Type 321. This enables the Type 200 Bailey Bridge to better cope with the needs of long-span bridges, such as when crossing deep valleys or rivers in mountainous areas, it can provide more stable support, reduce the deflection of the bridge, and ensure the safety and stability of the bridge.

2. **Heavy load transportation**
The design of the Type 200 Bailey Bridge allows it to carry larger loads and is suitable for scenarios where heavy vehicles or special equipment need to pass. For example, in military operations, the Type 200 Bailey Bridge can carry tanks and other large and heavy vehicles to ensure the rapid passage of military equipment. In the civilian field, such as mining transportation, large equipment handling and other scenarios, the Type 200 Bailey Bridge can also meet the needs of high loads.

3. **Adaptability to complex terrain**
The modular design of the 200-type Bailey Bridge enables it to flexibly adapt to various complex terrains. In mountainous areas or unstable geological conditions, the 200-type Bailey Bridge can enhance the stability and adaptability of the bridge by adjusting the arrangement of the trusses and adding support structures. For example, in highway construction in mountainous areas, the 200-type Bailey Bridge can quickly build a temporary bridge to ensure smooth traffic during construction.

4. **Quick construction and disassembly**
The components of the 200-type Bailey Bridge are light, easy to assemble and disassemble, and can be quickly constructed and disassembled. This rapid response capability is crucial in emergency rescue or temporary projects. For example, in rescue operations after natural disasters, the 200-type Bailey Bridge can quickly build temporary passages to ensure the rapid passage of rescue materials and personnel.

5. **Long-term use and reuse**
The steel components of the 200-type Bailey Bridge are durable, have a long service life, and can be reused. This makes the 200-type Bailey Bridge not only suitable for temporary projects, but also for scenarios that require long-term use. For example, in infrastructure construction in some remote areas, the 200-type Bailey bridge can be used as a long-term transportation solution to reduce construction and maintenance costs.

6. **Special engineering needs**
The 200-type Bailey bridge can also be used for some special engineering needs, such as construction channels and temporary trestles for large underground projects. For example, in the Jincheng Plaza project, the 200-type Bailey bridge was used to successfully cross the adjacent subway line, solving the impact of the deep foundation pit construction on the subway construction and operation period.

7. **Multi-lane bridge construction**
The 200-type Bailey bridge can be assembled not only into a single-lane bridge, but also into a double-lane bridge, thereby expanding the scope of use of the bridge. This enables the 200-type Bailey bridge to provide a more efficient transportation solution in scenarios where multiple lanes are required, such as urban traffic congestion areas or large-scale event sites.

In summary, the Type 200 Bailey Bridge, with its high load-bearing capacity, large-span adaptability, rapid erection and disassembly capabilities, and durability, shows significant advantages and broad application prospects in special scenarios such as large-span bridges, heavy load transportation, adaptation to complex terrain, emergency rescue, long-term use, special engineering needs, and multi-lane bridge construction.
