METHOD FOR REINFORCING SLOPE FOR VEGETATION

摘要

The present invention relates to a method for reinforcing an inclined plane for vegetation comprising: a foundation ground construction step of strengthening a foundation ground by cutting a part of an inclined plane; a concrete construction step of forming a concrete layer; a felt construction step of covering with long fiber felt; a first ground cement construction step that the ground cement is strengthened and stacked to a predetermined height; a geogrid construction step of covering the upper side of the ground cement with geogrid; a grid stiffened frame installation step of installing a rhomb net of a PVC material on the front side of a grid stiffened frame plated with molten zinc (Zn) and installing the lower side of the grid stiffened frame to be overlapped and combined with one side of the geogrid; a rebar anchor installation step of fixating the other side of the geogrid with a rebar anchor; a perforated drainpipe installation step of installing multiple perforated drainpipes toward an inclined plane; a second ground cement construction step of filling around the perforated drainpipe with the ground cement and strengthening the same; and a soil banking step of stacking and strengthening a mixture in which 70-90 w% of soil and 10-30 w% of zeolite are mixed. The present invention is eco-friendly since rebar is plated and the soil is not contaminated after using a PVC coating net instead of EX metal and plants rooted on the inclined plane are not withered. Moreover, the present invention can prevent secondary damage by earth pressure during torrential downpours by connecting one end of the geogrid to the grid stiffened frame and fixating the other end of the geogrid with the rebar anchor and can save costs by using low-priced perforated drainpipes rather than drainage blocks.
