Damping system for municipal bridge engineering

The invention relates to a damping system for municipal bridge engineering. A two-stage type damping and buffering structure is adopted, and the two-stage type damping and buffering structure can be used for the vibration influence of a heavy-duty truck and a light car on a bridge, so that an automobile can have better trafficability when passing through the bridge, the influence of multi-frequency vibration generated by the damping structure on automobile running is reduced, and the service life of the automobile is prolonged. In addition, the damping elastic piece set is adopted instead of an elastic damper which is vertically installed independently, larger pressure can be borne, the service life is longer, and the damping effect can be stably achieved for a long time; when the bridge is subjected to transverse shear force, the movable supporting frames on the two sides of the longitudinal damping mechanism at the bottom of the bridge are matched with the damping elastic piece sets, transverse force can be
