Cross crossing structure of four-line common-channel railroad bridge
The invention relates to the field of railroad bridges, in particular to a crossing structure of a four-line common-channel railroad bridge, which comprises a line a and a line d which are communicated with a city A and a city B, and a line b and a line c which are communicated with a city C and a city D. The line a and the line d wrap the line b and the line c in a four-line common-channel range. When the line spacing S between the lower line and the upper line is smaller than the line spacing requirement St when a round-end-shaped pier is independently arranged, the height difference of the two rail surfaces of the double-layer gate-type pier needs to meet the condition that ha is larger than h1 + h2 + h3 + h4, h1 is the contact network influence height, h2 is the upper cover beam structure height, and h3 is the distance from the rail surface to the beam bottom. H4 is the combination height of the upper surface line simply supported beam bearing padstone. The method can effectively improve the utilization rate of the construction land, optimizes the overall investment of the railway, improves the aesthetic property of the railway engineering, and facilitates the engineering implementation.
本发明涉及铁路桥梁领域，具体涉及一种四线共通道铁路桥梁的交叉跨越结构，包括连通城市A和城市B的线路a、线路d，以及连通城市C和城市D的线路b、线路c，在四线共通道范围内所述线路a、线路d外包所述线路b、线路c，且在四线共通道范围内设置有双层门式墩，当下面线别与上面线别的线间距S小于独立设置圆端形桥墩时的线间距要求St时，所述双层门式墩的两轨面高差需满足ha＞h1+h2+h3+h4条件，h1为接触网影响高度，h2为上盖梁结构高度，h3为轨面至梁底距离，h4为上面线别简支梁支承垫石组合高度。本发明能够有效提高建设用地的利用率，优化铁路总体投资，提升铁路工程的美观性及有利于工程实施。
