Slope protection network is divided into two categories, one for Active Protection Network, two passive safety net. Active Protection Active Protection System is based wire rope wrapped cover all types of flexible net in the desired protective slope or rock, to limit the slope rock weathering or damage to soil and rock collapse (reinforcement effect), or rockfall control within a certain range of motion (envelope effect). Active Protection Network has a high flexibility, high protection strength, easy spreading. Adapt to any terrain slope, the installer standardized and systematic. The system uses die-cutting of installation, short duration, low construction costs. Special manufacturing processes and high corrosion preventive materials technology systems, determines the ultra life of the system. Systems engineering team can impact on the environment to a minimum, the protection zone can adequately protect the soil, rock solid, easy to artificial green, environmentally friendly. Passive protection is (additional layer of wire grille takes intercept small rockfall) by wire rope, ring networks, fixed system (anchor, anchor rope, dock and support rope) pressure ring and steel columns four major parts. Combination of steel columns and steel wire rope connected to form a whole, for the protection of the area to form a protective surface, thereby preventing the collapse of falling rock soil, slope protection play a role. Flexibility and strength of passive safety net system to intercept the transfer is expected to be sufficient to absorb and disperse impact energy of rockfall, energy dissipation ring design and the use of the system has been further improved impact resistance. Compared with rigid pulp interception and build retaining walls, changing the original construction process, so that the duration and funding reduced.
