[0003] However, there are still certain problems when using the existing guardrails:

[0004] At present, in hot weather seasons, sprinkler trucks are usually used to cool and clean the road surface. However, sprinkler trucks not only travel slowly, but also raise water mist and dust that easily affect drivers and pedestrians on the roadside. In the existing technology, a water spraying device is set on the guardrail to spray water and clean the road surface. However, the water spraying holes on the guardrail pipes are exposed to the outside world for a long time, which easily leads to external dust entering the holes when it is not spraying water, causing the inner holes to be blocked, resulting in the inability to spray water normally, affecting the cooling of the road surface.

[0005] In response to the above problems, an innovative design was carried out based on the original guardrail. Utility Model Content
