Description
Technical field
The present invention relates to a kind of anticollision barrier, belongs to traffic safety facilities field, prevents more particularly to a kind of Novel rotary
Hit tub highway crash cushion guardail.
Background technology
Anticollision barrier is a kind of very universal road traffic safety device, at some than relatively hazardous area, such as road
Turning, at exit and entry and place that the faster highway of speed etc. has danger be widely used, one
Aspect, the fluorogenic Reflective stripe set on anticollision barrier can effectively play a part of traffic prompting, on the other hand, when driving with
When anticollision barrier bumps against, a kind of anticollision barrier with shock-absorbing capacity is set, can be greatly huge caused by buffering collision of closed
Impulsive force, so as to greatly reduce serious consequence caused by traffic shock accident, and existing anticollision barrier is universal
All it is to be made using plastic or other material, it is not firm enough, and the poor-performing buffered, while anticollision barrier is universal now
Weight is all relatively lighter, is easy to be moved position, and the easily passing vehicle of scratch and pedestrian in the presence of external force collision,
Cause great potential safety hazard, it is easy to secondary injury is caused, under huge impact force action, due to the not enough heavily fortified point of its design
Gu impact resistant capability is not strong, and shock-absorbing capacity is not good enough, and existing anticollision barrier generally easily causes crash barrier body structure
Deformation, highway anti-collision guardrail are very important traffic safety infrastructure, and the highway in China is from developing the eighties
Come, it plays important influence to national economy and social development, and anticollision barrier is then that highway is extremely important
Safety guarantee facility, anticollision barrier can effectively play prevention warning effect and safeguard protection effect, can effectively reduce
Caused loss after accident occurs, vehicle, facility damage to obtain probability caused by effectively reducing accidental impact, reduce property loss
With the probability of casualties, the people's lives and property is protected not encroached on safely to greatest extent, and it is a kind of with preferably slow
The anticollision barrier of punching performance can absorb energy caused by shock by deforming, and farthest force errant vehicle to change
Direction, normal travel direction is returned to, prevents that vehicle is run-off-road, played a part of protecting vehicle and passenger safety, reduce
The probability of loss caused by shock accident, so it is higher, green to provide low a kind of good impact resistance, cost, long lifespan, security
The highway anti-collision guardrail that colour circle is protected, using effect is good is particularly significant.The accidents such as all kinds of shocks, it is often caused huge due to shock
Large impact power causes casualties and economic loss, loss caused by order to control shock to greatest extent, it is necessary to which exploitation is anti-
The preferable anticollision barrier of effect is hit, particularly in highway, one-level, Class II highway and the faster road of speed, provincial highway, county road
And the anticollision series engineerings ten such as the preferable anticollision barrier of anti-collision effect are built in the area such as country road scenic spot, large parking lot
Divide necessity, its main function is to prevent that improper driving vehicle runs off highway or passed through caused by faulty driver or other reasons
Median strip is swarmed into, and the traffic accident to track occurs, occupant's peace on protection trackside pedestrian, building, driver and Che
Entirely, while have induction pilot's line of vision concurrently, increase traffic safety sense and beautify the effect of highway environment.Based on anticollision barrier to height
Huge promotion and maintenance effect in the economic benefit of fast highway, social benefit and traffic safety, countries in the world are in anticollision barrier
Research and application aspect are all done a lot of work.According to information, between 5 years of 1,987 one 1992 years, the West Europe magnitude of traffic flow
16% is risen, and during 1,988 one 1992 years, German road accident rate have dropped 70% on the contrary;France and Spain also under
Drop 20% or so;The Traffic Accident Mortality of Britain is down to the vehicle of 1.1 people/hundred million by the vehicle of 1.8 people/hundred million.The traffic accident in recent years of west various countries
Caused by life and property loss why gradually reduce, the appearance of various novel traffic anticollision barriers and can not extensively using work(
Not yet.For this it is a series of the problem of, build crashworthiness height, strong shock resistance, intensity is high, non-deformability is big, resiliency
Anticollision barrier that can be good is very necessary, and the consequence of traffic accident produced by shock significantly can be controlled, can be effectively
Playing reduces the effect of casualties and economic loss probability.
