Abstract

The invention discloses a highway protective guardrail for improving the safety of speed limitation. The highway protective guardrail includes a base, a support column is welded on the base, the support column is fixedly sleeved with a load-bearing cylinder, the outer wall of the load-bearing cylinder is provided with a limit slide groove, the load-bearing cylinder is fixedly sleeved with a limitguard plate, and the limit guard plate is provided with a limit slide cavity. Multiple buffer mechanisms are arranged on the protection guardrail, and different buffer measures are used for limiting the speed of vehicles under different stress conditions so as to reduce the strong vibration caused by direct collision with the vehicles and to improve the stability of the vehicles at the time of speed limitation. An arc outer plate is driven to rotate through vehicle extrusion, so that the vehicles follow the arc outer plate for direction deviation, and thus impact strength is scattered; nitrogen is rapidly formed through vehicle knocking, an safety air bag is used for buffering protection of the vehicles and the protective guardrail, the stability of the vehicles at the time of speed limitation is easily improved, the safety of personnel is ensured, and meanwhile the damage degree to the guardrail is reduced.

Description

technical field [0001] The invention relates to the technical field of road safety construction, in particular to a road guardrail that can improve speed limit safety. Background technique [0002] Highway guardrail is the main form of semi-rigid guardrail, which is a continuous structure that is spliced ​​with corrugated steel guardrail panels and supported by main columns. It is mainly used to block and limit out-of-control vehicles to prevent traffic accidents caused by vehicles deviating from the lane. [0003] The existing highway guardrail basically adopts steel bracket structure, which is extremely rigid. When an out-of-control vehicle collides with the guardrail, it can be supported by the hardness of the guardrail itself, so as to block the vehicle and realize the speed limit of the vehicle. . However, the existing highway guardrails are extremely destructive to vehicles because they adopt a single steel structure; The vehicle itself is prone to relatively large ...
