High Energy Absorption Rockfall Protection Net "Robust Protection Net"

basic information

■ Ministry of Land, Infrastructure, Transport and Tourism NETIS Registration Number: HR-230013-A ■ (Public Interest Incorporated Foundation) Civil Engineering Research Center: Construction Technology Review Certificate No. 2401 (There are various conditions for the applicable range) ■ Applicable Range ◇ Possible rockfall energy: 200kJ, 400kJ, 700kJ, 1,000kJ, 1,400kJ, 2,500kJ, 2,700kJ, 5,000kJ - The anchors installed on the concrete reaction bodies at both ends of the experimental device are firmly fixed to strong H-shaped steel, and there is no energy absorption due to deformation or displacement of the anchors and surrounding areas, making it a rigorous testing condition for the components (ropes, cushioning devices, etc.). - The indicated possible rockfall energies are values confirmed using an experimental device with concrete reaction bodies installed at both ends. - When applying this method at an actual site, the supports and anchors will be installed directly into the ground. - The design load of the anchors installed at the actual site will be determined based on the loads measured during the experiments. - The anchor length will be determined based on the results of pull-out tests and ground data, and the specified load-bearing capacity will be confirmed through verification tests after installation.

Price information

The construction cost per unit will vary depending on the scale of the project and various conditions (such as the type and length of rock anchors, special coatings, and landscape coloring, etc.).

Applications/Examples of results

■Purpose: Rockfall Protection Facilities - Areas where there are sources of rockfall at the top of a long slope, with steep terrain extending down to the roadside. - Locations where the expected rockfall energy ranges from 150 kJ to 5,000 kJ. - Areas with topographical variations where a wider spacing of pocket-type supports is desired (10m to 19m). ■Track Record - Mainly consists of achievements in public works. https://www.rcnet.co.jp/example/list.php?cd=22 *For more details, please refer to the PDF materials or feel free to contact us.
