Embodiment Construction
[0054] like figure 1 Shown is a railway T-beam frame construction method based on continuous beam layout and replacement points. The bridge to be constructed is a railway bridge with a bridge length greater than 2km and a railway track laid on it. The bridge to be constructed includes the completed front The first bridge section 18, the unfinished rear bridge section 19 behind the front bridge section 18, and the middle bridge section 1 connected between the front bridge section 18 and the rear bridge section 19 and completed, the The middle bridge section 1 is a continuous beam, and the rear bridge section 19 is composed of multiple T-beams assembled. The bridge structure constructed is detailed in figure 2 .
[0055] In this embodiment, the railway track includes two steel rails 3 arranged along the bridge direction, and the two steel rails 3 are paved on the concrete sleeper 2, and a layer of stone ballast leveling layer 4 is installed on the bottom of the concrete sleepe...
