Description
技术领域 technical field
本实用新型属于公路交通设施设计领域,具体涉及一种降雪地区公路的热敏材料减速标线。 The utility model belongs to the field of highway traffic facility design, in particular to a heat-sensitive material deceleration marking for highways in snowfall areas.
背景技术 Background technique
降雪地区在冬季环境中,低温天气不仅会产生降雪,还会凝固路面中存在的水分,在路面上形成少量冰膜。冰膜与冰粒、积雪等相互作用下会严重降低公路路面摩擦系数,增加低温环境中车辆行驶的危险性。在冬季环境中行车,道路路面的变化通常不够明显,难以对驾驶员形成足够警示作用,驾驶员依旧按照通常行车速度行驶,或者行车速度仍然过快,在行驶至冰膜路段时则极易造成车辆轮胎打滑,发生交通事故。 In the winter environment of snowfall areas, low temperature weather will not only produce snowfall, but also solidify the moisture existing in the road surface, forming a small amount of ice film on the road surface. The interaction of ice film with ice particles and snow will seriously reduce the friction coefficient of road surface and increase the risk of driving in low temperature environment. When driving in a winter environment, the change of the road surface is usually not obvious enough to form a sufficient warning to the driver. The driver still drives at the usual speed, or the speed is still too fast. The tires of the vehicle slipped and a traffic accident occurred.
我国大部分地区冬季都存在零度以下的天气,部分地区像东北的则会有长时间的降雪天气,积雪在车辆作用下反复碾压形成冰膜,会进一步降低摩擦系数。此外,当气温徘徊在零度时,白天冰雪融化形成积水,夜晚积水凝固形成冰膜,此时驾驶员仍没注意到前方路面状况,同样也容易造成交通事故。在国内现有研究中,针对除冰方法已有很多,但大多是冰量较大时才会采取措施清理,而类似渗水路面的研究目前因造价较高,难以大面积推广,产生了在少量冰雪和零度左右天气的除冰的问题。通常,在预防交通事故方面,还可以通过降低车辆行驶速度来达到加强控制避免事故的效果,现有的降速措施中,减速带容易对车辆行驶造成隐患,限速标牌长期效果较低,控速标线在降雪天气中,容易被积雪覆盖,或者与积雪混合造成辨识困难,均难以有效发挥作用。 Most parts of my country have sub-zero weather in winter, and some areas like the Northeast will have long-term snowfall. The snow is repeatedly rolled under the action of vehicles to form an ice film, which will further reduce the coefficient of friction. In addition, when the temperature hovers at zero degrees, ice and snow melt during the day to form water accumulation, and at night the accumulation water solidifies to form an ice film. At this time, the driver still does not notice the condition of the road ahead, which is also likely to cause traffic accidents. In the existing research in China, there are many methods for deicing, but most of them will take measures to clean up when the amount of ice is large, and the research on similar water seepage pavement is currently difficult to promote in a large area due to its high cost, resulting in a small number of ice removal methods. The problem of deicing in ice and snow and weather around zero degrees. Usually, in terms of preventing traffic accidents, it is also possible to achieve the effect of strengthening control and avoiding accidents by reducing the speed of vehicles. Among the existing speed reduction measures, speed bumps are likely to cause hidden dangers to vehicle driving, and the long-term effect of speed limit signs is low. In snowy weather, speed markings are easy to be covered by snow, or mixed with snow to make identification difficult, and it is difficult to effectively function.
现有研究成果没有针对冰雪环境有效控速的设施,现在亟需能够降低冰雪环境公路车辆行驶速度,改善道路环境并降低冰雪环境公路交通事故率的设施。 The existing research results do not have effective speed control facilities for ice and snow environments. Now there is an urgent need for facilities that can reduce the speed of road vehicles in ice and snow environments, improve the road environment and reduce the rate of road traffic accidents in ice and snow environments.

具体实施方式 detailed description
下面结合具体实例对本实用新型做进一步说明。 The utility model will be further described below in conjunction with specific examples.
图1为本实用新型一实施例的结构示意图,图2为图1中道路右半幅横断面示意图,本实用新型提供一种降雪地区公路的热敏材料减速标线,它包括在公路段沿车辆行进方向铺设的若干个减速标线单元2,每个减速标线单元2包括普通标线层6,相邻的减速标线单元2的间隔沿车辆行驶方向逐渐缩小,每个减速标线单元2还包括设置在普通标线层6上、零摄氏度以上无色、零摄氏度以下变为有色的热敏变色材料层5。热敏变色材料层可随温度改变颜色,本实用新型利用的是变色温度临界值为零度、零度以上为无色、零度以下为有色的热敏变色材料,如电子授受类热敏材料,利用微胶囊等技术,当电子给予体主要为若丹明化合物时,在电子受体和溶剂的作用下会发生颜色变化,这种材料在现有技术中已经存在,并非本实用新型的重点,本实用新型的重点在于利用了这种材料的低温变色的特性,在降雪地区公路段进行了合理的应用,只要是满足“零摄氏度以上无色、零摄氏度以下变为有色”这一条件的热敏变色材料均可以用于本实用新型。 Fig. 1 is a structural schematic diagram of an embodiment of the utility model, and Fig. 2 is a schematic diagram of the right half of the road in Fig. 1.

The heat-sensitive color-changing material layer can change color with temperature. The utility model utilizes the temperature-sensitive color-changing material whose color-changing temperature critical value is zero degrees, colorless above zero degrees, and colored below zero degrees, such as electronic receiving and receiving heat-sensitive materials. For technologies such as capsules, when the electron donor is mainly a rhodamine compound, the color change will occur under the action of the electron acceptor and solvent. This material already exists in the prior art and is not the focus of the present invention. The focus of the new model is to use the low-temperature discoloration characteristics of this material, and it has been reasonably applied in the road section in snowy areas, as long as it meets the condition of "colorless above zero degrees Celsius, and colored below zero degrees Celsius" heat-sensitive discoloration All materials can be used in the present invention.
本实施例的工作原理为:在普通环境中,主要利用其不断减小的减速标线单元2的间隔对驾驶员形成车速过高的视错觉,从而达到降低车速的目的。在低温环境中,热敏变色材料层5达到转变临界点,材料中若丹明化合物通过释放电子并与电子受体和溶剂共同作用变为红色,提示部分区域或整体区域温度变化情况,对可能出现的冰膜进行预示,其视错觉减速效果依旧能正常发挥。在冰雪环境中,整体红色的标线组能够吸引驾驶员注意力,同时增强视错觉减速效果。 The working principle of this embodiment is: in common environment, mainly use the interval of the deceleration marking unit 2 to form an optical illusion to the driver that the vehicle speed is too high, so as to achieve the purpose of reducing the vehicle speed. In a low-temperature environment, the heat-sensitive color-changing material layer 5 reaches a transition critical point, and the rhodamine compound in the material turns red by releasing electrons and interacting with electron acceptors and solvents, indicating temperature changes in some areas or the entire area. The ice film that appears is foreshadowed, and its optical illusion deceleration effect can still function normally. In the ice and snow environment, the overall red marking line group can attract the driver's attention, and at the same time enhance the optical illusion deceleration effect.

In this embodiment, the number of deceleration marking units 2 is 10, and the specific values of y are 4.95, 4.44, 3.97, 3.54, 3.15, 2.8, 2.49, 2.22, 1.99, and the unit is m.
进一步优选的,如图1所示,道路边缘线1之间的道路由道路中心线3分为2条行车道4,所述的减速标线单元2铺设在行车道4的正中央,平行于车辆行驶方向。减速标线单元2设置在道路行车道中央,保证了在进行除雪工作及车轮反复碾压后标线单元能够尽快显示出来,从而避免了因除雪工作不全面或没有被车轮机械作用到而导致被冰雪等大面积覆盖失去作用的情况。 Further preferably, as shown in Figure 1, the road between the road edge lines 1 is divided into two lanes 4 by the road centerline 3, and the deceleration marking unit 2 is laid in the center of the lane 4, parallel to The direction of travel of the vehicle. The deceleration marking unit 2 is set in the center of the roadway, which ensures that the marking unit can be displayed as soon as possible after the snow removal work and the wheels are repeatedly rolled, thereby avoiding being blocked due to incomplete snow removal work or not being mechanically affected by the wheels. Situations where large areas of coverage such as ice and snow lose their effectiveness.
每个减速标线单元2的设计,均满足《JTG D82-2009公路交通标志和标线设置规范》中的相应要求,如图3所示,减速标线单元夹角7为90°,减速标线线宽8为0.3m,减速标线横向总长9为1.5m。在已有的普通标线层6上添加热敏变色材料层5,满足减速标线单元2在低温环境下使用条件的同时,也满足正常环境下的交通需求。 The design of each deceleration marking unit 2 meets the requirements of JTG According to the corresponding requirements in D82-2009 Specifications for the Setting of Highway Traffic Signs and Markings, as shown in Figure 3, the angle 7 of the deceleration marking unit is 90°, the width 8 of the deceleration marking is 0.3m, and the total horizontal length of the deceleration marking is 9 It is 1.5m. The heat-sensitive color-changing material layer 5 is added to the existing ordinary marking layer 6 to meet the use conditions of the deceleration marking unit 2 in a low-temperature environment and also meet the traffic requirements in a normal environment.
