The expansion device of railway bridges is an important connecting component between the ends of railway bridges, which plays an important role in the expansion joints and waterproof performance of the bridge ends. Its quality and waterproof performance will directly affect the durability of the entire bridge. The durability requirements for passenger dedicated railway bridges are high, and reliable and durable waterproof expansion devices must be used between beam joints to protect the beam body and the lower structure of the bridge. This expansion device is suitable for commonly used span bridges, ballasted and ballastless track structure bridges on passenger dedicated lines with speeds of 350 kilometers per hour and 250 kilometers per hour.
