Description

Technical Field

[0001] The invention relates to the technical field of road traffic safety signs, in particular to a device for reinforcing and preventing protruding road signs on expressways. Background Art

[0002] Raised road signs, also known as road spikes, are raised marking blocks fixed on the road surface to serve as marking lines. They can be used to mark center lines, lane dividing lines, and edge lines on highways or other roads; they can also be used to mark dangerous sections such as curves, entry and exit ramps, diversion markings, road narrowing, and road obstacles, and use their retro-reflective properties to remind drivers to drive in lanes.

[0003] Highway raised road signs are a type of traffic safety facility, mainly used to provide visual and tactile guidance and warnings to drivers at night or in low visibility conditions through their reflective properties and physical protrusions. They are usually installed on highway lane demarcations, edge lines, curves, entrance and exit ramps, guide markings, road narrowing, road obstacles and other dangerous sections to guide and warn drivers to stay in lane and avoid deviating from the driving trajectory, thereby improving driving safety.

[0004] However, the existing raised road signs still have some shortcomings and areas for improvement in actual use and installation. Most of the existing raised road signs are installed by the simplest punching installation. Although this installation method is simple, the overall stability is low. During long-term use, the raised road signs may be occasionally crushed by vehicle tires, which may cause the overall loosening or falling off. In addition, since the raised road signs are exposed to the outdoors, they are easily worn and damaged by vehicles and bad weather for a long time. Therefore, technicians in this field provide a highway raised road sign reinforcement and anti-falling device to solve the problems raised in the above background technology.
