Detailed information
-
"Improve the height and strength of the existing rockfall protection fence without removal or reinstallation." Traditionally, when the height or strength of a rockfall protection fence was insufficient, it was necessary to remove and reinstall the fence or raise it with concrete. The reinforced fence addresses this by installing additional support posts over the existing posts to increase the height, and by using a special wire net with cushioning fittings to efficiently enhance the energy absorption capacity against falling rocks.
-
"Construction can be carried out at a low cost." There is no need to remove and reinstall existing fences or to install new ones as in the past. Since existing fences can be reused, it is possible to carry out construction at a low cost. The construction period is also shortened, allowing for a reduction in the overall costs of the project.
-
With little waste material, we can minimize the environmental impact. Since there is no complete removal of the existing fence, we can reduce waste and keep the environmental burden to a minimum.
