BRIDGE AND METHOD OF ITS BUILDING Russian patent published in 2005 - IPC

FIELD: bridges, particularly for water crossing and erection technique for bridge building.

SUBSTANCE: method for bridge building involves forming filled support areas for building slipways adapted for assembling large sections of bridge span structure, wherein support areas are arranged along borders of water barrier to be crossed, for instance along banks of river or slopes of ravine, and extends beyond the borders, wherein bridge span structure is formed of single-way panel; arranging each bridge span structure by means of sliding carriers on support member rotated relative vertical axis and located on the support area, wherein support member has previously increased load-bearing capacity; turning sliding carriers by hydraulic jacks relative support members, wherein sliding carriers hold large sections having T-shaped cross-sections so that longitudinal axes thereof coincide one with another in plane and a gap of uniform width is formed between edges thereof facing each other; installing insertion panel in the gap; connecting the insertion panel with T-shaped sections to form single span structure. Projections of T-shaped sections facing each other are formed to provide greater moment in comparison with that created by opposite projections and the moment is compensated before sliding carrier rotation, for instance by counterweights or jacks.

EFFECT: increased building speed and reliability.
