Speed bump for municipal engineering

Abstract

The invention discloses a speed bump for municipal engineering. The speed bump comprises a base. A first placement groove is formed in the top of the base. A cavity is formed in the bottom of the first placement groove. A fixed block is arranged in the cavity. A placement block is arranged in the first placement groove. A second placement groove is formed in the side, facing the placement block, of the fixed block. A second placement block is arranged at the bottom of the placement block. An arc-shaped block is arranged on the top of the placement block. A plurality of protruding blocks are evenly arranged on the surface of the arc-shaped block. The top and the bottom of the fixed block are provided with buffering springs. The first placement groove is formed for placing the placement block, the bottom of the placement block is matched with the second placement groove in the top of the fixed block through the second placement block, and therefore the firmness between the placement block and the base can be improved; when the placement block is damaged, the placement block can be taken out to be replaced with a new placement block, and loss is reduced.

Description

technical field [0001] The invention relates to the field of municipal engineering equipment, in particular to a deceleration belt for municipal engineering. Background technique [0002] Speed ​​bumps, also known as speed bumps, are traffic facilities installed on highways to slow passing vehicles. The shape is generally strip-like, but also point-like; the material is mainly rubber, but also metal; generally yellow and black to attract visual attention, so that the road is slightly arched to achieve the purpose of vehicle deceleration. It is generally set up in highway crossings, industrial and mining enterprises, schools, residential areas and other sections where vehicles need to slow down and sections that are prone to traffic accidents. In the construction area, speed bumps are generally installed, and the existing speed bumps, due to structural reasons, the top of the speed bump is the most easily damaged, but once a part of the speed bump is broken, it must be repla...

AI Technical Summary

Problems solved by technology

It is generally set at road 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 construction area, speed bumps are generally also installed. Due to structural reasons, the top of the speed bump is the most likely to be damaged, but once a part of the speed bump is broken, it must be replaced as a whole.
