Problems solved by technology

After the car body collides with the guardrail, due to the reaction force, the car body will often rush into the middle lane in the opposite direction, and collide with other normal vehicles again, resulting in damage to other vehicles and further damage to its own structure, and even serious damage. lead to more tragic consecutive car accidents

Abstract

The invention relates to the field of highway traffic equipment, in particular to a guardrail with compound functions of vibration reduction and disaster prevention. The guardrail comprises an uprightcolumn arranged on a highway, wherein the upright column is connected with a guardrail plate through an energy dissipation device. The guardrail with the compound functions of vibration reduction anddisaster prevention is reasonable in design. On the basis of ensuring the functions of an existing conventional expressway guardrail, the guardrail can reduce the destructive force in the event of acollision, and prevent a vehicle body from bouncing onto other lanes at the same time to avoid a second traffic accident.

Description

technical field [0001] The invention relates to the field of road traffic equipment, in particular to a guardrail with composite function of vibration reduction and disaster prevention. Background technique [0002] On the expressway in our country, a large number of motor vehicle traffic accidents occur every year. Due to various factors, motor vehicles collide with guardrails, causing various tragic consequences. In order to reduce the loss of human life and vehicle property caused by the collision with the guardrail, it is not only necessary to adopt vibration reduction technology to reduce the direct mechanical damage when the car body collides with the guardrail, but also to reduce the speed of the out-of-control car body as soon as possible to prevent the out-of-control After the car body collided with the guardrail, it rebounded into the traffic lane and collided with other vehicles again, resulting in a secondary accident. [0003] The currently commonly used expre...
