A kind of flexibility highway waveform antirust guardrail
Technical field
The utility model relates to a kind of flexible highway waveform antirust guardrails, belong to building field.
Background technique
It in highway both sides and center, is run where vehicle is gone out outside road in order to prevent, design and installation high speed is public
Road guardrail.As highway, city intersection, overpass etc. are largely built, transportation network is increasingly intensive, and the whole world
Car ownership increases by a relatively large margin year by year, and traffic accident rate is in rise year by year trend.It can be found according to data statistics
There are about 250 shock center guardrail events on every 200 meters of highways every year on average, and this kind of event is other on expressway
As many as 3 times of type traffic accident, particularly, the accident to create greater casualties because guardrail is overly hard is quite a few, existing height
Fast highway protection is mainly rigid concrete guardrail, semi-rigid corrugated guardrail and flexible cable guardrail, from structure itself and safety
From the point of view of performance, concrete guardrail wall face-type structural can effectively contain that small vehicle drills out guardrail and can substantially prevent big heavy type
Vehicle runs off guardrail, can reduce the probability of major traffic accidents generation, still, since concrete is when bearing external load effect
Deformation occurs seldom, therefore the kinetic energy of the vehicle absorbed in collision process by guardrail is seldom, the dynamic shear force that collision vehicle is subject to
It is very big, easily vehicle is caused seriously to destroy, or even cause passenger's injures and deaths;Corrugated guardrail has good comprehensive mechanical property,
There are preferable resistance and guiding function to general vehicle collision accident, but the intensity of corrugated guardrail is not big enough, to big quality
Hot-short cannot be intercepted effectively;Cable guardrail is due to smaller with the contact area of vehicle in knockout process, the energy of absorption
It measures limited, only has relatively good interception and guiding role to the shock of car, be commonly applied to tourist attractions guardrail or small-sized
Vehicle special lane guardrail, in conclusion existing freeway guardrail has following defects that concrete guardrail is overly hard, it may
Cause vehicle angle of rebound excessive, causes subsequent chain traffic accident;The rigid board of semi-rigid corrugated guardrail, it is possible to multiplying
Member causes bigger injures and deaths;And the actual effect of flexible rope guardrail still have it is to be tested.
