Description

A new type of cement guardrail

technical field

The utility model relates to a novel cement guardrail.

Background technique

The traffic safety fence has become one of the important facilities on urban roads. It effectively regulates people's traffic behavior and brings people a sense of security. With the increase of people's travel, the number of automobile vehicles increases, and traffic accidents It also shows an increasing trend year by year, causing the problem of people or vehicles colliding with the guardrail. Once the collision occurs, the guardrail will be damaged and the safety will be reduced. Therefore, the guardrail must be rebuilt and a large amount of construction funds have been invested. The construction period is also very long. And at present, in order to strengthen urban greening, flower pots are placed on the guardrail, but in case of a vehicle collision guardrail accident and a heavy snowstorm, the flower pots may fall under the bridge, which is prone to secondary accidents that injure passers-by. At the same time, once this greening method encounters heavy rain, the rainwater in the flower pot will overflow with soil, which will pollute the road surface and guardrail, and the maintenance cost will be higher.
