Bridge anti-collision guardrail

The utility model provides a bridge anti-collision guardrail which is used in cooperation with a reinforced concrete anti-collision guardrail, can make full use of an old guardrail, reduces the reinforcement and reconstruction cost of the guardrail, does not change the appearance form of the guardrail and the size of a collision face, and comprises a steel sleeve plate, a cavity is formed in the steel sleeve plate, one end of the cavity is provided with an opening, and the other end of the cavity is provided with an opening. The reinforced concrete anti-collision guardrail is embedded in the opening, the end, away from the opening, of the steel sleeve plate is a high-position intercepting part used for increasing the intercepting height of the anti-collision guardrail, and a waveform impact part is arranged on the high-position intercepting part and used for enhancing the structural strength and buffering energy absorption of the impact face of the high-position intercepting part.
