A method for construction of metal arch span of a bridge includes construction of mounting supports, mounting of raised construction of arch sections with closing to single system. According to the method assemblage of onshore sections of stiffening girder is performed on platforms, and channel ones – on assembly jig, assembled channel stiffening girders by means of roll-out pier are reloaded to floating pier, with towing to bridge site, those are placed to mounting supports, after that onshore and channel sections of stiffening girder are combined to continuous system, one performs building-on of mounting supports to total height for possibility of mounting arch blocks, after that one performs mounting of arch. |
