交通划线

What is the deceleration belt? Guizhou traffic line tell you!

定义

Definition

也叫减速垄,是安装在公路上使经过的车辆减速的交通设施,形状一般为条状,也有点状的,材质主要是橡胶,也有是金属的,一般以黄色黑色相间以引起视觉注意,使路面稍微拱起以达到车辆减速目的,一般设置在公路道口、工矿企业、学校、住宅小区入口等需要车辆减速慢行的路段和容易引发交通事故的路段,是用于减速机动车、非机动车行使速度的新型交通专用安全设置。减速带很大程度减少了各交通要道口的事故发生,是交通安全的新型专用设施。汽车在行驶中既安全又起到缓冲减速目的,提高交通道口的安全。目前,减速带在世界各地的公路中得到了广泛的使用。

Also called Ridge Road, is installed in the vehicle through the reduction of transportation facilities, the shape of strip is also a dot, the main material is rubber, there is metal, usually with a yellow black and white to attract visual attention, make the road slightly arching to achieve the deceleration of the vehicle, the vehicle generally set on the road, industrial and mining enterprises, schools, residential entrance to slow sections and easy to cause traffic accidents Road, is used for the slowdown in motor vehicle speed of the new traffic special security settings. The deceleration belt greatly reduces the occurrence of traffic accidents, and is a new type of special facility for traffic safety. The vehicle is both safe and cushioning in driving, so as to improve the safety of traffic crossing. At present, the deceleration zone has been widely used in highways around the world.


橡胶减速带

Rubber deceleration belt


交通划线提醒是根据车行驶中轮胎与地面特殊橡胶的角度原理设计,用特殊橡胶制成。是一种设置在公路道口,工矿企业,学校,住宅小区等入口处用于减速机动车,非机动车行使速度的新型交通专用安全设置 。该产品与原来水泥垄,钢管相比,橡胶减速带具有减震性,抗压性极好,寿命长,对车磨损少,噪音少,黄黑相间,色彩分明,无须每年再涂漆,美观大方等特点。使用减速带产品之后,很大程度减少了各交通要道口的事故发生,是交通安全的新型专用设施。

It is designed according to the angle principle of the tire and the special rubber on the ground, and is made of special rubber. It is a new special traffic safety device set at the entry of highway crossing, industrial and mining enterprises, schools, residential quarters, etc., which is used for decelerating motor vehicles and non motor vehicles to run at a speed. Compared with the original cement ridge and steel pipe, the rubber deceleration belt has the characteristics of shock absorption, excellent compression resistance, long life, less wear to the car, less noise, yellow and black interphase, and distinct colors, and no need to paint again every year, which is beautiful and generous. After the use of the deceleration belt, it greatly reduces the occurrence of traffic accidents, and is a new type of special facilities for traffic safety.

问题与发展

Problems and development

在1997年以前市场上只有国外公司在生产和销售橡胶减速带,它配有反光珠。在国外它还有一个别名叫“躺着的警察”,意思是说车辆到这里,就像见到警察一样要减速。当时国内主要是用水泥和铸铁做减速带。橡胶减速带有一定柔软度,在车辆撞击时没有强烈的颠簸感,减震、吸震效果好。白天看到黑黄相间,晚上看到反光珠反射光线,特别醒目。安装简单,维护方便。后来全国众多的橡胶生产厂家模仿起这种款式。

Before 1997, only foreign companies were producing and selling rubber decelerates in the market. It was equipped with reflective beads. In foreign countries, there is a person called "the policeman lying down", meaning that the vehicle is here, like the police to slow down. At that time, the domestic mainly used cement and cast iron to make deceleration belts. The rubber deceleration has a certain degree of softness, and there is no strong bump in the impact of the vehicle, and the effect of shock absorption and shock absorption is good. In the daytime see the black and yellow phase, the reflection of the reflection of light in the evening, especially striking. Easy to install and easy to maintain. Later, a large number of rubber manufacturers throughout the country mimicked the style.

在减速带两边的中央各有一个小孔,是安装孔,用膨胀螺丝将减速带固定到路面上的。所以当车辆碾压减速带时最受力的地方是安装孔位,最先撕裂的部位也是连接孔位,于是减速坡脱落,钢钉露出。一颗颗钢钉突出路面会着刺破车轮轮胎。造成这种情况的主要因素是偷工减料,用回收橡胶在添加大量低成本的添加剂,材料强度大大下降。要避免这一问题,就要

In the middle of the deceleration belt, there is a small hole in each side, which is the installation hole, and the deceleration belt is fixed to the pavement with the expansion screw. So when the vehicle is rolling down the deceleration zone, the most important place is to install the hole position. The first tear area is the connection hole, so the deceleration slope falls off and the steel nail is exposed. One of the steel nails protruded the road to pierce the wheel tires. The main cause of this situation is to reduce the strength of the material, and the strength of the material is greatly reduced by adding a large amount of low cost additive to the recycled rubber. To avoid this problem, it is necessary
