The present invention relates to a buried rail structure, more specifically, to simply form the structure of the rail to be installed on the track slab, not only can be installed more easily, but also to facilitate the drainage to run the railway vehicle stably It relates to a buried rail structure that can be.

In general, rails of railroads are intermittently installed with sleepers on gravel or concrete track slabs, and fixing rails to sleepers using rail fixing devices such as fixing bolts and spring clips.

In this case, the heavy wheels of the train pass through the sleepers sequentially, applying a large force to the sleepers at regular intervals, causing vibrations, and the vibrations propagate through the sleepers and the track slabs to the surrounding area, resulting in damage to the structure and surrounding precision equipment. It causes various vibration related problems such as disturbance of operation and generation of structure borne noise.

In addition, the shock vibration generated when the wheel passes the rail joint is transmitted to the surroundings through the propagation path as described above, causing the noise problem with the vibration. And noise generated between the rails and the sleepers and structural noise due to vibration of the rails themselves, thereby causing noise pollution. The vibration and noise problems of railways cause more serious problems in historic buildings, bridges and tunnels.

And, when the wheel of the train passes between the sleeper and the sleeper, the rail is bent, and thus the contact between the wheel and the rail of the train is not constant, thereby increasing the wear of the wheel and the rail. Wear of the wheels or rails of such a train is a big problem in itself, but this causes a lot of noise and vibration. In addition, as the rail is bent, friction occurs at the rail fixing part on the sleeper, and noise occurs along with the wear of the rail, and the rail fixing device is frequently damaged or loosened due to a large load applied to the rail fixing device. do.

In order to overcome this problem, a gutter is formed in a portion of the rail of the track slab to be installed, the lower part of the rail is installed in the gutter, and the gap between the two rails is precisely adjusted, and then a fixing member for fixing the rail to the gutter is provided. Landfill rails have been developed that install and bury rails.
