The present invention relates to a multi-stage rockfall protection bar on a road near a slope, and more particularly, is installed in front of a natural or artificially formed inclined surface to prevent rockfall or spilled soil from invading the road, and the blocked soil is piled up, It's about a multi-stage roadside rock protector on a slope near a slope where the panels change and open up to accommodate more soil and rock.

In general, sloped hills on the side of roads with poor landscaping works often cause unjust damages to vehicles or people who pass by stones or soil due to floods or winds. In order to solve this problem, in the past, rockfalls have been prevented by tying ropes to cover inclined hills, but this is only a primitive one-sided, and rockfalls cannot be sustained for a long time. For this reason, there are always insecure elements, and not only consciously risk the vehicle or people passing these roads of Yasan, but also have defects that are not aesthetically beautiful.

When a road or building is built along a hill or ridge, part of the ground is cut off, resulting in a constant slope. Since the inclined surface is artificially formed, its surface may be unstable and easily collapsed by rainwater and sea ice, or part of a rock wall may fall off and fall. Therefore, when these rocks fall on a driving vehicle or a building in which a person resides, it causes a great deal of human and material damage.

Thus, by using a method such as covering the inclined surface with a revetment block or installing a structure for forming a vegetation zone, falling rocks and earth and sand are prevented. However, these methods directly cover the surface of the inclined surface to prevent the falling of the falling rocks and soil itself, and may not be applicable as described above depending on the environment or the characteristics of the inclined surface. For example, such as a slope formed of a rock wall or a slope formed with a vegetation zone.

Thus, in these areas, rockfall protection nets are placed between roads or buildings and slopes to block falling or falling soils, thereby protecting the driving vehicle or buildings and those residing in the buildings from falling rocks and soils. However, the conventional rockfall protection net is composed of posts laid at predetermined intervals along the bottom of the slope and metal meshes connected between the posts, so that the loads transmitted from the rockfalls and soils depend only on the fixing force between the posts and the ground. Inevitably, it could not be absolutely safe from heavy rocks and earth and sand.

The present invention has been made in order to solve the problems described above, it is installed between the slope and the road, but spaced apart from the slope by a predetermined interval to be fixed horizontally so that the falling rock or earthenware in the space therebetween, Even if the earth and sand are excessively flowing from the slope, the two-stage and three-stage panels are deformed to provide a multistage rockfall protection system on the road near the slope, which allows a large amount of rockfall to be accommodated.
