MOBILE SPAN OF BRIDGE AND METHOD FOR ITS TRANSPORTATION AND ASSEMBLY

摘要

FIELD: construction.SUBSTANCE: method for transportation and assembly of a bridge span is determined by span design. The mobile bridge span comprises a traffic area made of longitudinal middle main block and two side cantilevers, each made as capable of folding to the middle above the traffic area and is hingedly connected by longitudinal edges to the main block. Each side cantilever of the traffic area is equipped with a pavement cantilever hingedly connected to the free longitudinal edge of the side cantilever as capable of folding above the traffic area, and the main block comprises two bearing beams of double-tee type with support surfaces in the extreme lower position. Each side cantilever of the traffic area is equipped with a folding longitudinal bump stop. Each pavement cantilever is equipped with a folding railing barrier. The main block comprises a rail track, besides, the top of the rail head does not protrude the level of the traffic area. The rail track may be set for a track of 1520 mm and a track of 1435 mm.EFFECT: using the invention makes it possible to increase efficiency and to simplify assembly works as a span is installed in a bridge structure, to expand its functional capabilities.8 cl, 4 dwg
