Background
2008.04.09, publication No. CN100379927C, discloses a method for constructing a road isolation green belt guardrail by using waste tires, and the isolation green belt guardrail constructed by the method can generate better buffering and energy absorption effects when collision occurs. The guardrail made of waste tires is fixed on the ground through foundation bolts 3, the foundation bolts are easy to rust after soil filling and tree planting, the fixing force between the guardrail and the ground is poor, and the guardrail is easy to push away from the original place when colliding with passing vehicles.
The chinese utility model discloses an urban traffic energy-absorbing road guardrail that 23 days disclosed, publication number is CN207998812U in 10 months in 2018, this utility model discloses a block net that nylon woven through being equipped with high strength carries out the kinetic energy to colliding the vehicle and absorbs, avoid the rigidity collision, reduce the vehicle loss, simultaneously through being equipped with the scroll spring leaf, carry out further absorption to car kinetic energy, avoid the vehicle to turn on one's side, protect driver and crew's safety, compare traditional road guardrail, the effect that not only has isolation lane still has better guard action. The nylon is also named as nylon, has better weather resistance indoors, is very easy to age and cannot be durable when being exposed to sun and frost outdoors, and the volute spring leaf is easy to rust. The structure is complex on the whole, the cost is high, and the popularization and the application are not facilitated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is how to overcome the above-mentioned defect of current highway isolation barrier, provide a high energy-absorbing zigzag environmental protection highway guardrail with low costs, weatherability is strong, longe-lived, and buffer capacity is strong.
For solving above-mentioned technical problem, this high energy-absorbing zigzag environmental protection highway guardrail, including stand and guardrail, the stand interval is buried in the concrete foundation of adapted highway, and the guardrail divide into the N section, and N section guardrail end to end fixes on the stand its characterized in that: each section of guardrail is a zigzag hyperbolic guardrail, each section of zigzag hyperbolic guardrail is provided with two or three arc-shaped longitudinal bulges, the projection of each section of zigzag hyperbolic guardrail on the horizontal plane is in a V shape, the middle and two ends of the guardrail are respectively provided with an arc section bent inwards, the number of the upright columns is 2N +1, the axes of the arc sections at the two ends and the middle arc section of each section of zigzag hyperbolic guardrail are respectively provided with an upright column, the lower end of each upright column is embedded into the concrete base, the upper part of each upright column is provided with an annular boss, the upright column above the annular boss is also sleeved with a waste wheel hub, the waste wheel hub is provided with a matched waste tire, the lower edge of the waste wheel hub is fixed with a fan-shaped supporting plate, the outer edge of each fan-shaped supporting plate is fixed on a lining plate, the lining plate is attached to the inner side wall of the arc section of the zigzag hyperbolic guardrail and is riveted and, the sun shield is provided with a through hole in the center and sleeved on the upright post through the through hole, wherein N is a positive integer.
So designed, it is not difficult to see from the cross section: two or three arc longitudinal bulges on the zigzag hyperbolic guardrail can be easily seen in the horizontal plane projection: the zigzag hyperbolic guardrail is in a V shape. A plurality of zigzag hyperbolic guardrail end to end connection is the zigzag, still be equipped with old and useless wheel hub and junked tire on the stand. When the passing vehicle collides with the waste tires, the buffer and energy absorption functions can be well played, the kinetic energy of the collided vehicle is uniformly and smoothly reduced, and casualties are reduced to the maximum extent.
By 2018, the quantity of motor vehicles in China reaches 3.27 hundred million, wherein 2.4 million vehicles are kept, and 2 million vehicles are broken through by small passenger vehicles. Meanwhile, a large number of cars and car tires must be scrapped every year. Each scraped car has at least four hubs and tires. After scrapping, the existing method only recycles scrap automobile steel, and the tires and other plastic and rubber materials are only treated as waste garbage, so that the environmental pressure is high, and the birth of the patent undoubtedly finds new application for the waste hubs and the tires.
In many running vehicles, each 8-10 kilometers of running, when the tires are required to be replaced, most tires can be inflated normally, and only the surface patterns of the tires are worn. The waste tire is used on the high-energy-absorption zigzag environment-friendly road guardrail disclosed by the patent, the air is inflated to 50% of the normal tire pressure, the buffering and energy-absorption effects are better, and the residual value of the waste tire can be fully exerted. The waste tire can not be inflated, and can play roles of buffering and energy absorption by virtue of the elasticity of the waste tire.
The sun shield can be made of metal plates or composite plates coated with waterproof layers, and can effectively slow down the aging of waste tires.
Preferably, a light barrier is fixed at the top of each upright post. So design, when the night is crossed, the light that the barn door can block the car of inclining on the adjacent road and jets out, drives safelyr.
Preferably, a fluorescent layer is arranged on one side of an outward protrusion part facing the direction of the coming vehicle of each section of the zigzag hyperbolic guardrail. So design, drive night, it is safer.
The utility model discloses high energy-absorbing zigzag environmental protection highway guardrail has with low costs, buffering energy-absorbing effectual, and longe-lived advantage both can be used as highway isolation guardrail, can be used as highway roadside guardrail again, is particularly suitable for highway to use.
