Railroad bridges are structures that a railroad spans a river, lake, straits, valley or other obstacle, and are constructed to achieve a grade crossing of a railroad line with a railroad line or road. It is often necessary to lay a plurality of track slabs along a track line to form a track. The track slab is a novel under-track component in the structural form of a slab for supporting and securing a rail and distributing the load transmitted by a train through the rail to an under-slab foundation.
The traditional track system usually adopts fastener mechanism to support the rail, and fastener mechanism is discontinuous to the support of rail, and the rail has the suspended section, and when the train went, the rail can produce vibration mode, and wheel rail contact relation is not good, and rail wearing and tearing are big.
