1.Expansion Joint for Bridge structure is simple
2.Easy installation for construction
3.Obviously reduce noise

     1.Bridge expansion joints are to meet the requirements of the deck deformation, usually between two beam ends, between the beam end abutment or bridge hinged position expansion joints.   

    2. Expansion joints in parallel and perpendicular to the bridge axis in both directions can freely retractable,solid and reliable vehicles should be smooth, no jumps and noise; to be able to prevent the infiltration of rainwater and garbage soil into blocking; installation, inspection, conservation to eliminate
dirt must be simple and convenient. Set at expansion joints, railings and bridge deck pavement should be disconnect
