With trough bridges, the roadway slab isn't arranged over the longitudinal girders like it is on a deck bridge, but is situated between the main girders and lower than the upper edge of the main girders. The utility model relates to a kind of trough type bridge frame, comprise: horizontal curved is logical, horizontal threeway, curved logical, top perpendicular tee joint, upper angle perpendicular tee joint, below perpendicular tee joint, straightway in vertical curved logical, vertical lower. Trough bridges featuring thick deck plates have proven to be the ideal bridge design for short-span overbridges. with crossbeams underneath the track plate. Web plates are in many cases welded on to stiffen the trough walls. Trough bridges therefore stand out with a lower construction height and, among others, are used. ABSTRACT: The IronOre line between Narvik in Norway and Luleå in Sweden faces challenges with aging bridges and an increase in allowable axle loads. In this line, reinforced concrete trough bridges constitute about 50% of the bridge population; therefore, they are crucial for the country's economy. (1) A. The invention discloses a kind of comprehensive trough type bridge frame, including trough type bridge frame, ground hole, bolt mounting holes, bolt sleeve, connector, bolt, cover plate, thread tapping and cable, the two ends of the trough type bridge frame are mounted on the bolt mounting holes.
