Description

Technical Field

[0001] The utility model relates to the technical field of speed bumps, in particular to a combined road speed bump for urban road traffic engineering. Background Art

[0002] Speed ​​bumps are traffic facilities installed on roads to slow down passing vehicles. They are generally strip-shaped or dot-shaped. They are mainly made of rubber, but also metal. They are usually yellow and black to attract visual attention. Speed ​​bumps slightly bulge the road surface to achieve the purpose of slowing down vehicles. They are generally installed at highway intersections, industrial and mining enterprises, schools, and residential entrances where vehicles need to slow down and where traffic accidents are likely to occur. Most existing speed bumps are made of rubber, but the rubber material is easily deformed after being squeezed by vehicles for a long time, which eventually leads to the need to replace the speed bumps, which increases the cost of the speed bumps and is more troublesome to replace.

[0003] The application number is 202320769402.2, which discloses a combined road speed bump for urban road traffic engineering, and relates to the technical field of speed bumps, including a speed bump body and an arc-edge speed bump, one side of the speed bump body is fixedly connected with a connecting block, the top of the connecting block is provided with a connecting hole, and the inner side of the arc-edge speed bump is respectively provided with a connecting block or a limiting groove corresponding to the speed bump body. The utility model uses a T-shaped connecting block and a limiting groove, and completes the combined splicing by inserting the connecting block on one side of the speed bump body into the limiting groove and fixing it with the connecting hole and the docking hole using connecting bolts, thereby improving the connection stability of the speed bump body, and at the same time, by providing a clamping groove and movably clamping a buffer pad inside the clamping groove, the overall buffer pad cooperates with the internal buffer block for buffering when the vehicle passes, thereby reducing the impact of the vehicle on the single speed bump body, and reducing the probability of the single speed bump body being easily separated.

[0004] However, there are some shortcomings. The combined road speed bump for urban road traffic engineering uses the overall buffer pad to cooperate with the internal buffer block to buffer when the vehicle passes, thereby reducing the impact of the vehicle on the single speed bump body and reducing the probability of the single speed bump body being easily separated. However, in actual application, the device cannot guarantee that the speed bump will not be deformed externally and internally after being squeezed by the vehicle for a long time. The speed bump still needs to be replaced after long-term use, which is more troublesome. Utility Model Content
