Restoration method of the Forest Road Cut-slope Using Gabion System with Vegetation Base Materials

摘要

PURPOSE: A method for restoring the slopes of forest roads is provided to simultaneously achieve stabilization and the vegetation of a slope by employing a gabion system with vegetation base materials where a part of the gabion system allows the passage of water and is buried in the slope. CONSTITUTION: A method for restoring the slopes of forest roads is as follows. A gabion frame in a square or rectangular shape is made by repetitively twisting iron wires. The interior of the gabion frame is covered with coconut palm fiber net, non-woven fabric, or jute fiber net. The gabion frame is filled with rubble and the surrounding forest soil and trees are crushed. The crushed soil and trees fill in gaps between the rubble in order to enable the sprouting and rooting of plants. The gabion structure is fixed with a plurality of piles, where a part(321,324) of the gabion structure is buried in a slope. Designated plants are dispersed on the exposed part(322,325) of the gabion structure.
