[0001] The present application relates to the technical field of bridge damping, and in particular to a large-diameter stacked steel wire damper structure and a construction method thereof. Background Art

[0002] After the construction of a bridge is completed, in order to prevent damage or even collapse of the bridge due to earthquakes or the bridge's own vibrations, dampers that can absorb shocks and resist earthquakes are usually installed close to the ground. The seismic isolation devices used on bridges mainly include rubber (lead core, high damping) seismic isolation bearings, friction pendulum seismic isolation bearings, viscous fluid dampers and metal yield (steel) damping bearings.
