Sleeper bolting elastic road junction

Abstract

The invention relates to a sleeper bolting elastic road junction, mainly comprising a rubber pavement panel, a road junction prestressed concrete sleeper, connecting screws, a C type boltless fastener and a bumper pad under rail. Nylon cannulas are pre-embedded on the concrete sleeper; the concrete sleeper is paved on a railway roadbed; the rails are fixed on the concrete sleeper; the bumper pad under rail is arranged between the rails and the concrete sleeper; external sides of the two rails are paved with panels respectively; a middle pavement panel is integrally designed according to a width between the two rails; connecting screws fixe the middle pavement panel, the external pavement panels and the concrete sleeper. Each pavement panel and the concrete sleeper form an integrity; the rails and the concrete sleeper form an integrity, so as to increase integral stability, security, anti-compression and impact resistance of the road junction, and thoroughly change a phenomenon of pavement panels and a wood sleeper affecting each other. The complementing bumper pad under rail is arranged under an iron subplate for vibration damping and noise reduction; a roadbed can damp vibration, reduce noise and also can isolate and evacuate rainwater, prevent integral sink of track bed and lower later maintenance costs.

Description

technical field [0001] The invention relates to a level crossing of a railway and a highway, in particular to a pillow body bolted elastic crossing with noise reduction and shockproof functions. Background technique [0002] The railway crossing is the main throat in the railway transportation and road transportation. For many years, asphalt, concrete slabs, wooden and steel structural slabs have been used for pavement. With the development of the railway and highway transportation industry, the shortcomings of these crossing slabs are becoming more and more obvious, mainly in the following points: the strength of the asphalt pavement is not enough, and it is cracked, deformed, soft and damaged after long-term heavy pressure; The combination between the rails and the sleepers is not firm, loose and unstable, and easily broken and damaged; the wooden pavement is mechanically worn and rotted quickly, and it is easy to form potholes; the surface of the steel structure is slippe...
