BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guardrail reinforcement structure using a high-tension square net and a buffer bumper,

The present invention relates to a guardrail reinforcement structure using a high-tension square net and a buffer bumper, and a construction method thereof.

Generally, guard rails are installed on both sides of the road for the safety of road traffic, and they are installed mainly to prevent cars from falling off the roads on highways and national roads, or as a central separator for separating the center of roads .

Guard rails also represent simple fenced facilities on the edge of a road or bridge to deter pedestrians or animals.

On the other hand, in roads where there is insufficient access to animals, road kill occurs frequently due to the animals suddenly invading the road, and when weeds grow too much on the roads, It is also a threat to the driver's visibility.

In recent years, structures for protecting the driver against the intrusion of such animals and weeds have been developed to be installed on the roads and courts on the outskirts of the city, on national highways and highways adjacent to the hills.
