High Stiffness 321 Bailey Bridge For TemporaryBridge With Large Span
Bailey Bridges which are portablesteel bridge have been widely used in various fields, its most importantfeature is to achieve a variety of spans, bear carrying capacity, light andhandy components, easy to dismantle and strong adaptability can be quicklycompleted with simple tools and manpower.
Bailey bridge panel consists ofpanels, pins, post end, bolt, chord reinforcement, truss bolt and chord bolt.
It consists of four parts, such as truss main beams, bridge decksystem, connecting system and structure foundation.
Bailey Bridges Introduction
Bailey Bridge is a standard bridge equipment, adopted extensively and themost popular in the world.Bailey Bridges Features
1. High strength and big stiffness, relative to the concrete bridge can bereduced trabecular high and self-respect
2. Due to the steel isotropic, quality of a material is uniform and modulus ofelasticity, that make steel bridge in the working condition and calculationcompared with the assumption
3. Bailey bridge generally prefabricated in factory, site assembledby pins and bolts; the construction period is short, processing convenient andnot affected by seasonal effect.
4. Bailey bridge is suitable for industrialized manufacture and veryconvenient to transport.
5. Bailey bridge is easy to repair and replace, long lifetime,material can be recycled.Each unit constructed in this fashion creates a single 10-foot-long(3.0 m) section of bridge, with a 12-foot-wide (3.7 m) roadbed. After onesection is complete it is typically pushed forward over rollers on thebridgehead, and another section built behind it. The two are then connectedtogether with pins pounded into holes in the corners of the panels.
For added strength up to three panels (and transoms) can be boltedon either side of the bridge. Another solution is to stack the panelsvertically. With three panels across and two high, the Bailey Bridge cansupport tanks over a 200-foot span (61 m). Footways can be installed on theoutside of the side-panels. The side-panels form an effective barrier betweenfoot and vehicle traffic, allowing pedestrians to safely use the bridge.
Bailey Bridges Application
It is mainly used for setting up single-span temporary Bridges, ensuringthat various vehicles with crawler load of 500KN and lower than tire load of300KN (axial pressure of 130KN) pass through rivers, broken Bridges, gulliesand other obstacles, and can be used to repair damaged Bridges, and can also beused to build construction towers, supporting frames, gantry frames and otherassembled steel structures.Bailey Bridges Competitive Advantage:
