TECHNICAL FIELD
[0001] The utility model relates to the field of highway guardrails, in particular to a cable guardrail. BACKGROUND
[0002] The disasters such as wind-blowing snow and wind-blown sand often occur in the highways in Xinjiang region, and the affected sections account for more than half of the operating highways, which causes great hidden dangers to traffic safety. As for wind-blowing snow and wind-blown sand, when the wind carries the medium through the guardrail, due to the disturbance of the guardrail to the airflow, a weak wind area will be formed on the road surface, thereby causing the sand and snow to deposit on the road surface, and the medium accumulation exceeding 30cm will interrupt the traffic, and when the wind is stronger, it will also cause the problem of low visibility, resulting in traffic accidents.
[0003] Chinese patent 202122638764 1 discloses a cable guardrail, which comprises a plurality of cables. When a vehicle collides with the guardrail, each tensioned cable can buffer and guide the vehicle through tensile deformation, and the plurality of cables can further enhance the guiding effect and improve the protection ability of the guardrail. Each cable is connected with a row of columns, and the columns can support the cables. When a collision occurs, part of the collision energy can also be transmitted to the columns through the cables, thereby improving the protection strength of the cable guardrail. The distance between adjacent cables is 10cm-20cm, which can neither weaken the protection effect due to too far distance nor easily accumulate snow and sand due to too close distance, i.e. the present application can ensure the protection effect without causing snow and sand accumulation on the highway, and is especially suitable for use in windy and snowy areas. However, the structure of the patent is simple, and the function is single. The wind speed cannot be effectively reduced after the sand and wind pass through the guardrail, and there is still a great safety hazard when the vehicle passes through the guardrail, especially when the visibility is greatly reduced, which cannot provide road guidance for the passing vehicle.
