Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] A railway box girder traversing and falling device according to an embodiment of the present invention includes a traversing support and a falling support.
[0041] Specifically, the traversing support includes a steel pipe pile group and a slideway assembly. There are two groups of steel pipe pile groups, which are respectively arranged on the sides of two piers. The steel pipe pile group includes a first steel pipe pile 1 , a second steel pipe pile 2 , a third steel pipe pile 3 , a pile top longitudinal beam 4 and a first pile top distribution beam 5 . The first steel pipe pile 1, the second steel pipe pile 2 and the third steel pipe pile 3 are distributed at intervals along the transverse extension direction of the box girder. The first steel pipe pile 1 is a single row of steel pipe piles, and the first steel pipe pile 1 has three and are located below the...
