Overlapping vibration-proof rail joint

The utility model relates to a lapping type vibration-proof rail joint which comprises two rail heads and is characterized in that: each rail heads is provided with a tenon and a lapping platform which are corresponding to each other; when the rail heads are connected with each other, one tenon is lapped on the other lapping platform and mutually lapped and meshed; through the fixation of a fixing splint, two mutually staggered and parallel expansion and contraction joints are formed, the length of which is half of the prior expansion and contraction joint of a rail. When wheels run through the rail heads, the wheels in turn run over the two expansion and contraction joints, because the expansion and contraction joint run over each time is only half of the prior expansion and contraction joint of the rail, the percussive force is greatly reduced; because the connection mode makes the two tenons meshed with each other, the defect of uneven rail surface of the rail joint due to shake around of the rail heads, s
