Description
Technical field
The present invention relates to road safety protection technique field, more particularly to buffer anticollision structure at a kind of road and crossing.
Background technology
With developing rapidly for the transport developments such as China's highway, bridge, traffic capacity has greatly improved.But I
The automobile quantity of state also increasingly rapidly surges, the thing followed, and vehicle collides the traffic accident of guardrail in road and bridge
It is on the increase, causes to run off the roadway, the situation for crashing into both sides ramp and falling down from the bridge is of common occurrence, caused casualties, property
Loss and environmental disruption etc. are very huge.To mitigate the order of severity of traffic accident to greatest extent, automobile is prevented to run off public affairs
Road, the important engineering that safety barrier is road safety is set.Guard rail should possess following safe performance indexes：Stop work(
Energy, pooling feature and guide function.Barrier functionality refers to that guardrail has enough intensity so that guardrail do not thrust by vehicle and
Pass through, or guardrail is not crossed and ridden more by vehicle.Pooling feature refers to occupant when running into impact, guardrail can slow down to vehicle and
The ability of impact acceleration suffered by passenger.Guide function refers to after colliding guardrail that collision vehicle is smoothly led to direction of traffic
Go out and the ability for state of resuming operation.According to safety barrier national standard, guardrail is divided into stiff safety fence (concrete guardrail), and half just
Property guardrail (beams of metal post fence) and flexible safety fence (Cable Barrier).Stiff safety fence such as concrete guardrail mainly by arrangement of reinforcement come
Meet guardrail intensity, energy is absorbed by itself rigid deformation or material damage, if guardrail is overly hard to lose buffering
Function, vehicle is caused to stop sliding completely when being hit, it is extremely serious to vehicle damage, it is easier to cause the direct wound of occupant
Harmful, basic steadiness directly affects guardrail block and the performance of guidance quality in addition.Half just made of metal material processing
Property guardrail and flexible safety fence have preferable ductility, enable to be returned by resistance adjustment direction, safety after Vehicular impact guardrail
To traveling lane.After particularly guardrail hits damage, concrete guardrail and guardrail wires structure bulky, local maintenance and replacing
All it is inconvenient, structure linkage interface needs specially treated, is not easy to quick, convenient construction on highway.
