Falling stone impact prevention device for bridge pier

The invention discloses a falling stone impact prevention device for a bridge pier. The falling stone impact prevention device comprises first impact prevention structures arranged on the four circumferential faces of the bridge pier correspondingly and second impact prevention structures arranged on the four bridge pier corners correspondingly. The first anti-impact structure comprises a plurality of first anti-impact units, a distance is formed between every two adjacent first anti-impact units, and the distances are configured to be deformation displacement of the first anti-impact units when the first anti-impact units are impacted; the second anti-impact structure comprises a plurality of second anti-impact units, a distance is formed between every two adjacent second anti-impact units, a distance is formed between each first anti-impact unit and the corresponding second anti-impact unit, and the distances are configured to be deformation displacement when the second anti-impact units are impacted.
