The main cause of damage to the highway guardrail
The highway guardrail board can bring a good and tidy effect to the road, as well as the safety brought by the management of the management personnel, the maintenance of the vehicle, and the reduction of injuries caused by accidents.
There are two main reasons for damage to the wave guardrail:
1. Natural factors. The partition board device on both sides of the road suffers from bad weather, rendering the surface of the guardrail board with varying degrees of oxidation damage. When the guardrail board rusts, it will speed up the secondary utilization and oxidation speed of the guardrail board, and then it can greatly affect the time of reducing the service life of the guardrail board.
2. Human factors. When their vehicle collides, because the wave guardrail has excellent anti-collision and energy absorption effect, it is not simply destroyed, but also has a good maintenance effect with the vehicle and the passengers. When the road is repaired or other major analysis needs are connected, the guardrail posts at the opening can be easily pulled out and removed to open up the passage and facilitate the management of safe passage of vehicles. When the corrugated guardrail is in the maintenance of the vehicle, the personnel safety partners themselves will be subject to corresponding hazards.
Therefore, after the road guardrail is installed, maintenance and repair are periodically performed to ensure the service life extension of the guardrail.
