The present invention provides a crash barrier. Bases are provided with grooves, first rotating accommodation slots are formed in the bottoms of the grooves, first inclined walls, side walls and second inclined walls which are connected in sequence at the openings of the first rotating accommodation slots, first rotating balls are provided in the first rotating accommodation slots, stand columns are provided on the first rotating balls, second rotating accommodation slots are formed in the lower ends of the stand columns, second rotating balls are provided in the second rotating accommodation slots, the second rotating balls are connected with support rods, sliding slots in which the lower ends of the support rods are provided are formed in the first inclined walls, inner springs are provided between the lower ends of the support rods and the bottom ends of the sliding slots, outer springs sleeve the parts, positioned outside the sliding slots, of the support rods, wire rope stretching devices are provided in the stand columns, a corrugated board is provided between the two stand columns, two rows of fixing holes are formed in the corrugated board in the top and bottom, an upper wire rope sequentially passes the row of the fixing holes in the top, and a lower wire rope sequentially passes the row of the fixing holes in the bottom. According to the crash barrier, the impact force of vehicles in accident can be buffered and released, so that the impact damage to vehicles in accident and passengers by barriers is decreased.
Description
technical field [0001] The invention relates to the technical field of road guardrails, in particular to an anti-collision guardrail. Background technique [0002] With the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents are currently the most frequent occurrences in road sections or highway bridge sections. In order to reduce the occurrence of traffic accidents, various guardrails are installed on both sides of the road. Since the guardrails are made of iron structure and inelastic, rigid guardrails have strong protection ability. However, when a car collides with the guardrails, Under the action of instantaneous impact load, the guardrail basically does not move or deform. The energy absorption during the collision process depends on the plastic deformation of the car itself, the frictional contact between the car and the guardrail, and the car's movement along the barrier. The climbing of the guardrail and...
