Description

Technical Field

[0002] With the increasing development of economy and technology, people's requirements for the comfort of rail transit are getting higher and higher. The construction of rail transit in major central cities is accelerating, and the requirements for the shock absorption technical conditions and construction efficiency of the track plate system are gradually increasing. In the traditional ballastless track plate system, the adjustment layer is mostly filled with self-compacting mortar poured in mortar bags, the surface stiffness is relatively large, and the vibration reduction effect is poor. In sections where vibration reduction is required, prefabricated shock-absorbing pads are usually pasted and laid on the adjustment layer under the track plate, and the gap between the boss and the track plate is filled with boss resin separately. The components and their installation processes are numerous and complicated, with low efficiency and poor integrity. In addition, the shock-absorbing pads are prone to falling off or offset during use.

[0003] The Chinese patent with announcement number CN203923803U fills liquid polyurethane under the positioned track plate, and after curing, it bonds with the track plate and the base as a whole to form a shock-absorbing and sound-insulating elastomer layer, which significantly improves the vibration reduction and sound insulation effects. However, the fence positioning, sealing and pouring port settings are relatively complicated, and the boss resin still needs to be poured separately, which requires more processes.

[0004] Therefore, we proposed an integrated vibration damping pad track plate system. Utility Model Content
