A Bailey panel, also known as a Bailey truss or Bailey beam, is a modular pre – fabricated steel truss structure for bailey bridge. It is composed of upper and lower chords, vertical members, and diagonal members which are welded together. The ends of the upper and lower chords have male – female joints, and there are connection pin holes for trusses on the joints.
Characteristics of Bailey Panel
Simple Structure: It consists of several basic components, making it easy to understand and assemble.
- Convenient Transportation: The components are lightweight and can be disassembled into smaller parts, facilitating transportation and handling.
- Rapid Erection: With connection methods such as pins, it can be quickly set up, saving construction time.
- High Load – bearing Capacity: It has a relatively high load – bearing capacity and can meet the load – bearing requirements of various engineering scenarios.
- Good Interchangeability: The components are standardized, and Bailey panels from different batches or locations can be replaced with each other.
- Strong Adaptability: It can be flexibly combined and adjusted according to different engineering needs and site conditions.
Types and Specifications of Bailey Panel
Common types include the “321″ Steel Bridge and the HD200 – type Prefabricated Highway Steel Bridge.
- The “321″ Steel Bridge is widely used in China. It has the advantages of lightweight components, easy disassembly and assembly, and strong adaptability. It is suitable for loads such as vehicle – 10, vehicle – 15, vehicle – 20, crawler – 50, and trailer – 80. The clear width of the vehicle lane on the bridge deck is 3.7m, and it can be combined into various simply – supported beam bridges with different spans.
- The HD200 – type Prefabricated Highway Steel Bridge has an increased truss height, which improves its load – bearing capacity, stability performance, fatigue life, and reliability.
Applications of Bailey Panel
Highway Bridge Construction: Bailey panels can be used to build temporary or permanent highway bridges. When crossing rivers, valleys and other complex terrains, it can quickly construct a safe and reliable passage structure, providing access for construction vehicles and personnel. It can also be used as a launching nose, a part of the bridge – erecting machine and other equipment in bridge construction.
- Railway Engineering: They are used to build temporary railway bridges. When railway lines cross rivers, valleys and other complex terrains, they ensure the safe passage of railway trains. They can also be used as maintenance platforms and temporary support structures during railway construction and operation.
- Municipal Engineering: In urban construction, they can be used to build temporary footbridges, construction platforms or as temporary support structures for some large – scale activities. For example, in road construction and pipeline – laying projects, they provide convenience and safety for construction.
- Water Conservancy Engineering: They can quickly build temporary bridges or passages to facilitate the transportation of construction materials and the access of construction equipment by construction teams across rivers, lakes and other water areas. They can also be used to build diversion dikes, diversion dams and other diversion and cofferdam structures to control and guide water flow around the construction area.
- Building Construction: In the construction process of high – rise buildings and large – scale stadiums and other complex projects, they are often used as construction platforms, scaffolding or temporary support structures to provide a safe and stable working environment for construction personnel.
- Disaster Relief: After natural disasters such as earthquakes and floods, they can be used to quickly build temporary bridges to quickly restore traffic and provide strong guarantees for the rapid passage of relief supplies and personnel. They can also be used to build temporary shelters and rescue passages.
- Mining Engineering: They are used to build temporary roads and bridges and other facilities to facilitate mining and transportation work in mines and improve the production efficiency of mines.
- Power Line Construction: They are often used to build temporary crossing frames across rivers, lakes and other obstacles to ensure the smooth erection of power lines. In the later maintenance of power lines, they can also be used as maintenance platforms and temporary support structures.
