Regular maintenance is one of the indispensable links. Highway guardrail products adopt regular segmental maintenance and long-distance isolation. During the regular inspection of highway guardrails, road maintenance workers should pay special attention to whether the guardrails on both sides are damaged, open welding or severely corroded.
Winter is here and it always rains. Therefore, it is inevitable that the road guardrail will get rusty. So, what to do with those rusty guardrails? Now, let's find out.
1. Regular maintenance is one of the indispensable links. Highway guardrail products adopt regular segmental maintenance and long-distance isolation. During the regular inspection of highway guardrails, road maintenance workers should pay special attention to whether the guardrails on both sides are damaged, open welding or severely corroded. In case of such problems, the Highway Management Center should be notified in time, and it will send professional maintenance personnel to clean up, replace or perform other maintenance work on the site.
2. Record the specific size of the rusted traffic facilities on the road guardrail, and use a hammer to test the specific toughness of the guardrail. If there is a large area of paint peeling or corrosion, it proves that the guardrail here has been severely corroded, and the vulnerability of the internal metal components can be imagined. The best way is to replace the waste fence products in time.
3. Rusty guardrails should also be cleaned up in time and sorted for recycling. As a common high-speed shell building material, it still has a wide range of applications after professional recycling and degradation treatment. Among them, the main material for galvanized and electroplated plastic coatings on the surface of highway guardrails is oxide coatings. In the production process of the highway guardrail, a layer of anti-corrosion equipment will be evenly applied on it, which is more conducive to improving the anti-corrosion effect of the corrugated guardrail.
The corrugated guardrail is a kind of tough semi-steel protective equipment, which can stop the complex country and force the vehicle to return to the normal route when the vehicle collides. The highway guardrail is installed in the middle of the road. When the vehicle is out of control, it can effectively prevent the out-of-control vehicle from running into the lane and causing a secondary collision.
