Description
Technical Field
The utility model relates to a road safety technical field, concretely relates to be applicable to mountain area low grade highway quick response formula guardrail.
Background
In recent years, in a low-grade road in a mountain area, particularly in a long and large downhill section, due to the fact that the grade of the road is low, the leveling index is poor, the road is seriously damaged, traffic accidents of automobiles in the downhill section are frequent, and the automobiles are damaged if the grade of the road is light, so that traffic jam is caused; when the vehicle is turned over, the vehicle rushes out of the road and rolls down the slope, so that serious casualty accidents are caused, and the current situation is that the highway in the mountainous area is not fresh frequently.
The reasons for this situation are mainly: 1) the mountainous road is limited by terrain conditions, the road level and longitudinal indexes are poor, the design speed per hour is low, and passing vehicles often exceed the design speed per hour; 2) the road is narrow, the sight distance is limited, the road condition cannot be judged in advance, and particularly, the road is easy to rush out at a curve; 3) mountain winding roads in mountainous areas generally grow up and descend, large trucks have large inertia, and are forced to rush out of roads due to poor braking effect in rainy and snowy days; 4) the road surface of the low-grade road is not wide enough.
In order to solve the above problem, a guardrail is generally arranged on one side of a mountain road.
The guardrail arranged at present generally consists of an upright post and a guardrail plate positioned on the upper part of the upright post, wherein the guardrail plate is made of steel plates, and the upright post and the guardrail plate are made of rigid materials and are also in rigid connection. When the automobile is out of control and collides with the guardrail plate, the guardrail can prevent the automobile from rushing out of the road. Practice proves that the guardrail plate with the structure has no buffering function, and the guardrail plate is broken and an out-of-control automobile rushes out of a lane under the strong impact force of the out-of-control automobile at high speed, so that the automobile is damaged and people die; especially, the broken guardrail plate is more serious in injury, and the danger that the automobile rushes out of the road cannot be effectively prevented. On the other hand, the guardrail plate made of the steel plate is also penetrated, the compressive resistance and the anti-collision effect are lost, and the service life is short.
And the setting height of current guardrail is higher, and evenly lays along mountain area highway one side, under the narrower condition in road surface, causes great oppression for navigating mate easily to influence navigating mate's driving safety.
