Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a speed reduction belt structure. Background Art

[0002] Speed ​​bumps are traffic facilities installed on the road to slow down passing vehicles. They are usually strip-shaped or dot-shaped and made of rubber. They are usually installed at road intersections, schools, residential area entrances and other sections where vehicles need to slow down. They make the road surface slightly arched to achieve the purpose of slowing down vehicles. Since speed bumps are wearing parts, they need to be replaced regularly.

[0003] During installation, it is necessary to drill holes on the roadbed and then fix the speed bumps to the roadbed with expansion bolts. Every time the speed bumps are replaced, it is necessary to drill holes on the roadbed and install expansion bolts again. On the one hand, this will cause the roadbed to be damaged, and on the other hand, the installation is very inconvenient. Moreover, speed bumps are installed in parallel in multiple pieces. When vehicles pass over the speed bumps, the speed bumps will be crushed, impacted and rubbed, which can easily cause adjacent speed bumps to be misaligned, thereby causing the speed bumps to separate from the roadbed.
