Guardrail is the most basic protective equipment for expressways, and high-speed guardrail plays a very important role in highway protection. We all want traffic accidents, but they happen every day. Accidents of the guardrail being hit often happen. What should we do if the high-speed guardrail is hit?

First, we observe and remove the damaged guardrails, and then check whether the nearby guardrails and columns are damaged. Sometimes we can’t check it with the naked eye. This is because we need to go through professional tools to test whether the surrounding guardrails Can achieve the effect of protection.

After removing the damaged guardrail, we need to install a new guardrail. When installing, we need to make perfect splicing to ensure the anti-collision grade coefficient, so as to achieve the protective effect.

If the column is damaged, we need to replace the column. After the column is buried, the soil should be compacted as much as possible, and it should not be lower than the previous road surface.

Finally, the rain cap of the column needs to be covered.

It is easy to overlook the daily maintenance of high-speed guardrails, and think it is irrelevant. In fact, the daily maintenance of guardrails is very important. If the guardrail is highly reflective, it is likely to cause a traffic accident. The original protective product has become a hidden danger of the accident. This violates the original intention of protection. Therefore, the maintenance of the guardrail should be paid attention to to reduce the reflection of the high-speed guardrail.
