本实用新型公开了一种柔性高速公路护栏，包括立柱和护栏板，特点是立柱与护栏板之间固定设置有柔性防阻组件，该柔性防阻组件包括筒状外壳和圆筒体，圆筒体设置在筒状外壳的内部，圆筒体与筒状外壳之间形成一个空腔，该空腔中填充有柔性材料。其优点是在立柱与护栏板之间设置柔性防阻组件，该柔性防阻组件为刚性的内外层之间填充泡沫铝，由于泡沫铝的高吸收冲击能力强，使得该柔性防阻组件具有良好的吸能效力和回弹能力，当车辆以一定速度和撞击角度撞击高速公路护栏时，该柔性防阻块可较大程度地吸收车辆的撞击动能，以阻拦车辆冲出路基或中央护栏同时使车辆以较小角度回弹返回正常车道。
The utility model discloses a flexible highway guardrail, which comprises a column and a guardrail board, and is characterized in that a flexible anti-blocking component is fixedly arranged between the upright post and the guardrail board, and the flexible anti-blocking component includes a cylindrical shell, a cylindrical body, and a cylinder The body is arranged inside the cylindrical casing, and a cavity is formed between the cylindrical body and the cylindrical casing, and the cavity is filled with flexible materials. The advantage is that a flexible anti-blocking component is set between the column and the guardrail. The flexible anti-blocking component is filled with aluminum foam between the rigid inner and outer layers. Due to the high impact absorption capacity of the foamed aluminum, the flexible anti-blocking component has good performance. When the vehicle hits the highway guardrail at a certain speed and impact angle, the flexible anti-blocking block can absorb the impact kinetic energy of the vehicle to the greatest extent to prevent the vehicle from rushing out of the roadbed or the central guardrail while using The vehicle bounces back to its normal lane at a slight angle.
Description
Technical field
The utility model relates to a kind of highway barrier, relates in particular to a kind of flexible freeway guardrail.
Background technology
In speedway both sides and central authorities, go out outside the road, place in order to prevent operational vehicle, design and installation freeway guardrail.Build along with speedway, city intersection, elevated road etc. are a large amount of, transportation network is increasingly intensive, and the growth by a relatively large margin year by year of the automobile pollution in the whole world, and the incidence of traffic accident is ascendant trend year by year.Can find on every 200 meters speedways, the central guardrail event of shock of 250 times is arranged approximately every year on average according to data statistics, and this class event is 3 times more than of other type traffic accident on the expressway, especially, quite a few because of the too hard accident that creates greater casualties of guardrail.
Existing speedway protection is mainly rigid concrete guardrail, semi-rigid corrugated guardrail and flexible cable guardrail.From structure itself and security performance, concrete guardrail metope formula structure can contain effectively that dilly gets out guardrail and can prevent that basically large heavy vehicle from running off guardrail, can reduce the probability that major traffic accidents occur.But, do the used time and deformation occurs seldom bearing external load due to concrete, therefore the kinetic energy of the vehicle that is absorbed by guardrail in collision process is seldom, the dynamic shearing power that the collision vehicle is subject to is very large, very easily causes the vehicle heavy damage, even causes passenger's injures and deaths; Corrugated guardrail has good comprehensive mechanical property, the general vehicle collision accident is had resist preferably and guiding function, but the insufficient strength of corrugated guardrail is large, can not effectively tackle the hot-short of large quality; The cable guardrail is because the contact area with vehicle in knockout process is less, and the finite energy of absorption only has reasonable interception and guide effect to the shock of car, often is applied to tourist attractions guardrail or compact car special lane guardrail.In sum, there is following defective in existing freeway guardrail: concrete guardrail is too hard, may cause the vehicle angle of rebound excessive, causes follow-up chain traffic accident; The hard sheet material of semi-rigid corrugated guardrail might cause larger injures and deaths to the occupant; And that the actual effect of flexible rope guardrail still has is to be tested.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly simultaneously makes as far as possible vehicle return to the flexible freeway guardrail of normal lane with the smaller angle resilience realize stopping vehicle and go out on the basis of roadbed or central guardrail.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of flexible freeway guardrail, comprise column and guardrail board, be fixedly installed flexibility between described column and described guardrail board and deter assembly, described flexibility deters assembly and comprises cylindrical case and cylinder, described cylinder is arranged on the inside of described cylindrical case, form a cavity between described cylinder and described cylindrical case, be filled with flexible material in described cavity.
The cross section of described cylindrical case is regular hexagon, described cylindrical case comprises the first side end face and the second side end face, described the first side end face is two side end faces parallel on cylindrical case with the second side end face, described column is fixedly connected with described the first side end face by the described flexible material of bolt-through, and described guardrail board is fixedly connected with described the second side end face by the described flexible material of bolt-through.
Described flexible material is foamed aluminium, and described foamed aluminium welding is filled in described cavity.
The distance of the center to of a described cylindrical case end points is 1/2 to 3/4 with the ratio of the radius of described cylinder.
Described column is cylindrical column, is provided with the inner concave that the outline with described cylindrical column fits on described the first side end face.
Described guardrail board is double wave shape steel plate.
The material of described cylindrical case and described cylinder is steel plate.
compared with prior art, the utility model has the advantage of: between column and guardrail board, flexibility is set and deters assembly, this flexibility deters filled and process aluminium between the ectonexine that assembly is rigidity, because the high impact-absorbing ability of foamed aluminium is strong, make this flexibility deter assembly and have good energy-absorbing effect and resilience, when vehicle clashes into freeway guardrail with certain speed and projected angle of impact, this flexibility obstruction block can absorb the shock kinetic energy of vehicle largely, vehicle is gone out roadbed or central guardrail makes vehicle return to normal lane with the smaller angle resilience simultaneously to stop.
