Bridge anti-seismic device with buffering energy-dissipation function

The invention relates to a bridge anti-seismic device with a buffering energy-dissipation function. According to the bridge anti-seismic device, the problem that existing bridge anti-seismic devices are designed after an earthquake acts on a bridge is solved. According to the technical scheme, the bridge anti-seismic device comprises an anti-seismic device body, the upper portion of the anti-seismic device body is detachably connected with a damp-proof layer, and the damp-proof layer is in an upward-protruding radian shape and is filled with a damp-proof material; an annular shell is providedwith a through hole, and a hole cover is mounted in the through hole in detachable and washable modes; a primary anti-seismic cabin is internally provided with a plurality of primary anti-seismic devices connected mutually and distributed circumferentially and evenly; a first-stage anti-seismic cabin is internally provided with a plurality of first-stage anti-seismic devices distributed circumferentially and evenly; a sec
