シビル安全心 List of Products and Services

■Overview The robust protective net is a high-energy absorption pocket-type rockfall protection net designed to efficiently absorb the energy of falling rocks that occur at the top of slopes and safely guide them to the bottom of the slope. It is made from a combination of high-strength wire mesh, wire ropes, and cushioning devices. It has been developed based on the performance verification methods described in the Rockfall Countermeasure Handbook (December 2017) and has been proven to meet the three performance requirements (safety, usability, and reparability). ■Features 1. The cushioning device is delivered after factory assembly, reducing the installation process and time during construction. 2. Full-scale performance verification experiments have demonstrated that after partial repairs are made to a specimen that has been loaded once, reloading shows that performance is restored to 100%. 3. Performance evaluation sheets and experimental reports have been organized and can be provided upon request. ■Lineup and Types There are two structures: the 'Net Type' (7 types), which eliminates vertical ropes and combines high-strength wire mesh with horizontal ropes and cushioning devices, and the 'Rope Type' (1 type), which combines wire mesh and high-strength ropes in a vertical and horizontal lattice structure. *For more details, please refer to the PDF materials or feel free to contact us.*

• Other civil engineering works

This method resists the sliding load of rock masses by using the pull-out resistance of the UB rope anchor through the rock anchor hanger cable, preventing the fall or sliding of the rock mass. By introducing a uniform tension force into the hanger cables, the structure is designed to distribute the load to all hanger cables in the event of external forces from an earthquake.

• Special Construction Method

The "Cross Control Net" is a rockfall prevention method that can collectively suppress the behavior of multiple boulders scattered across a slope. Thanks to the effects of control fittings and distributed fittings, it does not place excessive burden on anchors and wire ropes, while also being lightweight with fewer components, making it easy to install. 【Features】 ■ Prevents wire rope breakage with control fittings ■ Accumulates loads and transmits them evenly ■ Distributes loads to reduce the burden on components ■ Small anchors make installation easy *For more details, please download the PDF or feel free to contact us.
