Abstract
A water damping device includes a steel frame and a water-blocking cup; the device is immersed in the water and connected under the main bridge girder by wire ropes. One end of the water-blocking cup is provided with a blocking ring and a cover. The water-blocking cup cover is mounted between the cup and the blocking ring and is movably connected to the water-blocking cup. The blocking ring is used to prevent the water-blocking cup cover from opening towards the outside of the cup; an array of water-blocking cups is mounted on the steel frame along the downward direction of the water-blocking cup cover.
