Rubber bearing is a common bridge bearing product, with the following characteristics: simple structure, convenient processing and manufacturing, low cost, saving steel plate; With good elastic damping, it can reduce the impact of dynamic load on the collapsed structure and pier, and improve the mechanical performance of the bridge.

1, modified PVC rubber strip. The price is relatively low, due to different quality advantages and disadvantages, the price is generally between 6000 yuan and 15000 yuan per ton. Low-end products due to the use of waste, substitute plasticizer and high filling amount, to make the rubber strip poor elasticity, easy to hard, pungent taste, easy to migrate the frame material yellow, short service life. 2, thermoplastic EPDM rubber seal strip. The seal is a new material developed in recent years on the basis of technology introduced from abroad and domestic independent research and development, mainly with dry car doors and Windows seals, in recent years began to be used for building doors and Windows seals,
