Self-adaptive pavement deceleration strip

Abstract

The invention discloses a self-adaptive pavement deceleration strip, and relates to the technical field of deceleration strips. The self-adaptive pavement deceleration strip comprises a bottom plate,a casting is welded to the top of the bottom plate, drainage grooves distributed in a row shape at equal intervals are formed in the casting, front ends and rear ends of the drainage grooves penetratethrough the front side and the rear side of the casting correspondingly, a water accumulation preventing mechanism is arranged in the middle of each drainage groove, and a splashing preventing mechanism is arranged in each drainage groove; and the water accumulation preventing mechanism comprises a water collecting tank, a pin shaft, a sliding cylinder, a rotating piece, an air bag, a wire grooveand a stretching soft rib. According to the self-adaptive road surface deceleration strip, the water accumulation prevention mechanism is matched with the splash preventing mechanism, the height of accumulated water on the road surface serves as a signal for autonomous operation, flowing of road surface runoff in the direction towards a road surface drainage facility is effectively promoted, thedrainage effect is improved, and meanwhile the height of accumulated water around the deceleration strip can be controlled; and a road runoff flow velocity can also be hindered by reducing the accumulated water height.

Description

technical field [0001] The invention relates to the technical field of speed bumps, in particular to an adaptive road speed bump. Background technique [0002] Speed ​​bumps, also called speed bumps, are traffic facilities installed on highways to slow down passing vehicles. The shape is generally strip-shaped, and also dot-shaped; the material is mainly rubber, and there are also metal; generally yellow and black are used to attract visual attention, and the road surface is slightly arched to achieve the purpose of vehicle deceleration. It is generally installed on highway crossings, industrial and mining enterprises, schools, residential quarters, etc., where vehicles need to slow down and where traffic accidents are likely to occur. It is a new type of special traffic safety setting for reducing the speed of motor vehicles and non-motor vehicles. In the event of heavy rainfall, the water on the road is easily hindered by the speed bump during the flow process, causing th...

Problems solved by technology

In the event of heavy rainfall, the water on the road is easily hindered by the speed bump during the flow process, causing the water volume on the road to continue to rise. The increase in the height of the water will undoubtedly affect the normal driving of the vehicle, resulting in road safety. At the same time, because the speed bumps are usually set at the exits of densely populated facilities such as schools and residential quarters, the accumulated water blocked by the speed bumps is very likely to splash when vehicles pass by and affect pedestrians.
