Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as Figure 1~3 , a track structure suitable for high-speed railway bridges, including a bridge roof 1 and a track 2, the bridge roof 1 and track 2 structures of the present embodiment are all prior art structures, and the bridge roof 1 is an upper layer in a box girder structure Horizontal planks.
[0026] The structure of the track 2 is a traditional steel rail structure. The track 2 is supported on the rubber backing plate 3 at the lower end. There are buckle rails 4 on both sides of the track 2 to connect the track 2 and the backing plate 3 into one body. The buckle rail 4 is provided with bolts 5 The bolt 5 passes through the buckle rail 4 and the backing plate 3, and its lower end is anchored on the bridge roof 1 to fix the rail 2, the buckle rail 4 and the backing plate 3 on the bridge roof 1.
[0027] A convex bod...

The invention relates to the technical field of high-speed railway ballastless track structures, in particular to a track structure suitable for a high-speed railway bridge. The track structure comprises a bridge top plate and tracks anchored to the bridge top plate through bolts. The lower ends of the bolts are anchored to the upper end face of the bridge top plate, and grooves formed in the extending directions of the tracks are formed in the bridge top plate. Convex body bands are arranged in the grooves and are of prefabricated flexible concrete structures which are fixed between the tracks and the bridge top plate and used for supporting and buffering the tracks. The lower ends of the convex body bands are fixed into the grooves, and the upper ends of the convex body bands protrude out of the upper end face of the bridge top plate. The bolts perpendicularly penetrate buckle rails on the tracks and the convex body bands to anchor the tracks, the convex body bands and the bridge top plate to be of an overall structure, and leveling structures are arranged between the convex body bands and the bridge top plate. The track structure is simple in structure, a traditional bridge track structure is simplified, the track construction efficiency is improved, a large quantity of manpower and material resources are saved, and high popularization value is achieved.
Description
technical field [0001] The invention relates to the technical field of high-speed railway ballastless track structure, in particular to a track structure suitable for high-speed railway bridges. Background technique [0002] Ballastless track refers to a track structure system that uses an integral foundation such as concrete or asphalt mixture to replace the loose-grained gravel track bed, and the sleeper itself is made of concrete. It has been more than ten years since China's first ballastless track test section has been widely used. The structural form has also developed from CRTS Ⅰ type slab, CRTS Ⅱ type slab to the current CRTS Ⅲ type slab. In addition to these classic forms, there are also integral types. Road bed board and other non-mainstream forms. [0003] Compared with the development of the ballastless track, the railway bridge as the load-bearing foundation of the ballastless track has not been greatly adjusted, and the railway bridge of the prior art usually ...
