Details
       Expansion joints (beam end waterproofing devices) are important ancillary facilities at the beam end, and their quality directly affects the durability of the bridge. This expansion joint is a combination of aluminum alloy profiles and rubber bands, suitable for box girder structures, easy to install, and can be quickly replaced.
       Expansion joints are suitable for commonly used railway span simply supported and continuous concrete box girders. Curved bridges with a straight or curved radius greater than or equal to 1200m, ballasted and ballastless track structure bridges, single track and double track railway bridges.

The expansion joint design has an expansion capacity between 30-200mm. The stretching amount is divided into seven levels: 30mm (± 15mm), 60mm (± 30mm), 80mm (± 40mm), 100mm (± 50mm), 120mm (± 60mm), 160mm (± 80mm), 200mm (± 100mm).
