Rockfall protection "LDB-500" that can be installed in areas with little distance from the preservation target.
A rockfall protection fence with reinforced posts that has a small deformation amount during rockfall impact. The shock absorption device is easy to replace and has excellent maintenance characteristics.
This is a rockfall protection system with reinforced posts that can absorb rockfall energy up to 500 kJ and has a small fence deformation during rockfall impacts. The fence deformation is less than 2.0 m (1.34 m in full-scale tests), making it most effective in narrow locations such as alongside roads and railway tracks. 【Applications】 ● Rockfall measures in narrow installation areas ● Rockfall measures alongside roads and railway tracks 【Features】 ● The fence deformation is less than 2.0 m, so it does not encroach on construction limits. ● By rigidly connecting the upper chord and posts, low deformation is achieved. ● The performance of the protective fence has been verified through full-scale testing. ● Rockfall energy is absorbed by the balanced arrangement of impact-absorbing components (U-brakes) utilizing the bending deformation of steel, and high toughness and high strength posts made by combining H-beams and steel pipes. ● Each span has an independent structure, allowing for maintenance and repairs within a limited area. ● It can be installed directly on retaining walls or on the ground.

Company information
Since its establishment, our company has played a role in national construction, primarily focusing on the "ground improvement field" with our unique grouting method. Subsequently, in response to the changes in social infrastructure development, we have refined our technologies to adapt to the needs of the times and, at times, acquired new ones to expand our business scope. As a result, we have now established three main pillars: "ground improvement business," "slope disaster prevention business," and "pipeline business."
