There are tow types of slope network, and they are active protection slope network and passive protection slope network. They are usually used for prevention and protection of landslide.
Active protection-----Flexible network mainly wire rope net covers the slope or rock wall which need to be protected. It restricts the weathering and spalling or destroyed of rock and soil on slope surface and the rock avalanche or limits the rocks in the certain scope.
Passive protection-----consists of 4 main parts which are wire rope net, ring network, (steel grating if need to Intercept small blocks of rockfall), fixed system (anchor rod, anchor rope, base and supporting rope) pressure reducing ring and steel column. The contamination of steel column and wire rope net generate a protective surface thus the collapse of collapsed rock and soil will be prevented.
