The Bailey bridge system consists of three main components like, truss panels, transoms or floor beams, and stringers. Each unit, when assembled, creates a single, 10-foot- BRIDGE CONSTRUCTION PRACTICES USING bridge is 2,110 ft. long with a main span of 330 ft. This bridge was launched in two trains, one from each side of the river. Closure of the bridge was accomplished at mid-span of the main span. This method of construction can be applied to bridges made of either steel or concrete materials. Bailey Bridges - AngelfireBailey bridges are often installed by the cantilever launching method, in which the assembled bridge together with a "launching nose" is rolled out across the gap, without falsework or heavy equipment (see Figure 3). The cantilever method allows bridges to be quickly erected over rivers or deep gorges.
The Bailey Bridge, named after Sir Donald Bailey, was one such bridge developed for use in the second World War. The success of this bridge was due to its modular design and that it could be assembled with the minimum of heavy equipment. The bridge could be assembled on the bank and then pushed out over the river. Balanced Cantilever Construction of Precast Segmental BridgesBalanced cantilever erection is slower and requires more post-tensioning and pier-cap stabilization gear when the deck is supported on one line of bearings, but the erection equipment is lighter and less expensive, and the construction method is more fit to urban bridges with different span lengths and varying plan curvature. Compact bridge,CB100,Cb200 Bailey,truss,temporary bridge Cantilever Pushing Method:Restricted by construction site, giant erecting equipment often cannot enter the site.Simple-equipped cantilever Pushing Method is widely used to erect bailey bridge quickly and safely. It doesnt need giant erection equipment, and experienced workers can perform the bridge erection task after limited training.
The construction method depends mainly on topography and influences bridge cross-section design as well as span. Basically, four major techniques, such as balanced cantilever, advanced shoring, launching and span-by-span, are employed, along with conventional falsework or bridge heavy lifting operations.

Construct using precast beam Cast the first section of bridge Push the first section of Construction of the Precast Segmental Approach The precast segmental approach structure of the Sutong Bridge with 75m span length was constructed using balanced cantilever method. This precast segmental viaduct was characterized by deep foundation in the riverbed, 60m high columns connecting the main bridge and relatively long end spans in the balanced cantilever deck.

INCREMENTAL LAUNCHING METHOD OF BRIDGE Incremental Launching Method of Bridge Construction:For bridge decks greater than 250m in length, the method of incremental launching can be considered. With this method of construction the bridge deck is built in sections by pushing the structure outwards from an abutments towards the pier. It is most suited to the rapid construction of bridges  Segmental Bridge - an overview ScienceDirect TopicsThe gantries erect the hammers directionally from abutment to abutment, and the segments can be delivered on the completed bridge. Erecting two adjacent bridges simultaneously by shifting the gantry from bridge to bridge further accelerates construction, which may reach 2 + 2 segments per hammer per day (Figure 27.10). One or two hoists are used to lift and move the segments into position.

May, I925.] 6i 3 started. (Fig. I5. ) The new trusses were then assembled out- side of the old structure by cantilever method. The new sway bracing was placed between the members of the old spans. truss bridge Definition, History, & Uses BritannicaTruss bridge, bridge with its load-bearing structures composed of a series of wooden or metal triangles, known as trusses. Trusses are capable of supporting considerable external loads over a large span and use a relatively small amount of material, making them particularly useful for railroad and military bridges.
