Bridge rail structure suitable for large-span bridge and construction method
The invention discloses a bridge rail structure suitable for a large-span bridge and a construction method, and belongs to the technical field of bridge rails. The bridge track structure comprises a bridge assembly and a ballastless track. The bridge assembly comprises a large-span bridge, a continuous beam and a plurality of sliding beams, a beam seam is formed between the large-span bridge and the continuous beam, a first notch and a second notch form a positioning space, fine seams are formed between the large-span bridge and the sliding beams, between the continuous beam and the sliding beams and between any two adjacent sliding beams, and the width of each fine seam is smaller than that of the beam seam. Elastic pieces are inserted in the thin seams, the elastic coefficients of the multiple elastic pieces are sequentially reduced in the direction from the large-span bridge to the continuous beam, and the sliding beam located at the end of the positioning space is located in the first notch and crosses the beam seams. According to the bridge rail structure suitable for the large-span bridge, a steel rail telescopic adjuster does not need to be arranged, and therefore the production cost of the bridge rail structure is reduced.
本发明公开了一种适用于大跨度桥的桥轨结构及施工方法，属于桥轨技术领域。所述桥轨结构包括桥梁组件和无砟轨道；桥梁组件包括大跨桥梁、连续梁和多个滑动梁，大跨桥梁和连续梁之间形成梁缝，第一缺口和第二缺口形成定位空间，大跨桥梁和滑动梁之间、连续梁和滑动梁之间、任意相邻的两个滑动梁之间均形成细缝，各细缝的宽度均小于梁缝的宽度，各细缝中插装有弹性件，且从大跨桥梁至连续梁的方向，多个弹性件的弹性系数依次减小，位于定位空间端部的滑动梁位于第一缺口中，且跨过梁缝。本发明实施例提供的一种适用于大跨度桥的桥轨结构，无需设置钢轨伸缩调节器，从而降低了桥轨结构生产成本。
