Wiper type hot melt road marking and traffic safety line optimization
The construction of the scraper hot melt Guizhou marking line is mainly based on the cooperation of the hydraulic hot melting kettle and the hand pushing scribing machine. The two parts are divided into two parts: the heating pot, the heating coating and the hand pushing scribing machine. The construction principle as floor plastering, marking machine has two side with coating thickness to ensure the adjustment to a certain thickness, smooth on the road will be the hot melt paint scraping. Hot melt coating is heated to 180-2200 during construction, and the principle of scratch line operation is scraping and coating construction. At the beginning of construction, the solid powder coating is put into the melting kettle, melted and melted into the heat preservation hopper of the hand pushing type streak car, and then the melt melting coating is introduced into the marking bucket, and the insulation is kept to keep the coating in molten state. Start line, crossed the road. Thousands of workers fighting and fighting on the ground line adjustment gap, since crossed into the hot melt coating bucket under the paint bucket, advance crossed car, melt flow by gravity and wiped out a neat line, and automatically adjust the equipment evenly in the marking on the glass beads.
In the analysis of the hallucination of the road on the road, taking the American death highway as an example, this paper puts forward the use of 3D three-dimensional marking to deal with the illusion of road traffic illusion. Three-dimensional marking can make full use of visual hallucinations and one-sided phenomenon of human psychological factors, to drive through line sections of the driver to road or roadside obstacles such as hallucinations. Then, we can induce the driver to automatically descend the speed. It also has the advantages of low cost, notable effect, avoiding 1 damage to the road surface, and saving the repair and maintenance cost of the highway. When studying the road hallucinations generally, they usually divide their causes into 3 categories: the road alignment, the environment beside the road, and the inconsistency between the road alignment and the environment beside the road. In China, the two main categories of the road line and the road next to the road are mainly analyzed. The hallucinations caused by road alignment include hallucinations of curved paths, hallucinations of ramps and hallucinations of speed. The damage of the hallucination of the bend is the most severe.
In the past, all over the world because of the lack of real knowledge points of safety and safety markings. Annual traffic accidents and unnecessary traffic congestion and road closures. The formation of the economic loss of billions. So many countries from the public colleague Adam Bureau and marking production plant on the basis of marking outstanding facilities and clear brightness and give more thought to skid resistance. Because the European excellent marking implementation. Most countries in Europe through the European standard PrEN1436 in 1997. As a scientific rules for the brightness of sunlight and diffuse Qd. road light and humid environment and rainy conditions. Then the retroreflective brightness coefficient coefficient in the regulations to further improve the progress of the pavement marking a total of.
