Energy absorption type anti-impact safety guardrail

The utility model relates to an energy absorption type anti-impact safety guardrail. Stand column with cuboid structure, supporting fixing plates are evenly and fixedly arranged on the periphery belowthe stand column. A groove is formed in the side wall, close to a road, above the stand column. A spring II is fixedly arranged at the bottom of the groove; a fixed plate is fixed at the other end ofthe spring II; an energy absorption box is fixedly arranged on the side wall, opposite to the second spring, of the fixing plate. The energy absorption box is perpendicular to the stand column, and the other end is fixedly provided with a corrugated beam. Energy dissipation rods are hinged to the positions, corresponding to the stand columns, of the upper end and the lower end of the corrugated beam. A sliding block is fixedly arranged at the other end of the energy dissipation rod, T-shaped sliding grooves in the direction of the stand column are formed in the upper side and the lower side of the stand column respect
