New Material Design And Application Of Bailey Bridge

Mar 18, 2020

The vertical distance from the deck or the bottom of the rail to the bottom edge of the superstructure is called the height of the bridge building, which is called the height of the bridge from the bridge deck or the bottom of the rail to the low water level or the road below the bridge.Bailey Bridge 

Along the central line of the bridge, the horizontal distance between the ends of the side wall of the bridge abutment (the bridge with no abutment is the length of the carriageway of the bridge deck) is called the bridge length or the total length L (Highway bridge).Bailey Bridge 

The disassembly-type metal bridge is a complete set of fixed bridge equipment, usually including the upper structure, the adjustable height of the middle bridge foot, as well as special erection and loading equipment. This equipment is mainly used to set up and withdraw, use, loading, operation convenient, good maneuverability, can be used to set up a single span and multi-span low water bridge, but also to strengthen and repair the damaged permanent bridge.Bailey Bridge

There are wooden bridges, bridges, bridges, reinforced concrete bridge, prestressed concrete Bridge (sometimes referred to as three concrete bridges), steel bridge and Beam bridge. The wooden bridge is easy to corrode and used for temporary bridges. The compressive strength of stone and concrete is high and the tensile strength is low, mainly used in Arch bridge.Bailey Bridge

Due to the appearance of light and high strength materials, the improvement of mechanization of equipment, the progress of hydraulic equipment and welding technology, many national armies have adopted methods such as improving the structure integrity and erecting operation mechanization, so as to improve and develop the standard military bridge equipment continuously.Bailey Bridge 

Representative: The Soviet Union's heavy-mechanized bridge (TMM) and the Belt Bridge, the French Army's accompanying Bridge (PAA), the British Medium truss Bridge (MGB) and the federal German Army's Krupp fixed bridge and so on.

In order to meet the requirements of modern warfare, handy Bridge will further trend of precast, equipment and components to implement regional standardization, erecting machinery to achieve mechanization.Bailey Bridge 

The standard bridge continues to be integrated along the structure, the direction of mechanized operation will further increase the single span erection length of the fixed bridge, improve the load capacity and erection speed of the bridge, improve the maneuverability of the vehicle, improve the standardization, serialization and generalization of the equipment, and make it adapt to the requirements of the air maneuver.Bailey Bridge
