According to the present invention, an elastic drain material to improve a soft ground having a corrugated core comprises: a core where opened and curved surfaces are alternately disposed to face each other to be connected to be corrugated to have a predetermined width, generating an elastic restoring force with respect to a pressure applied from the outside; and a filter material enabling pore water contained in the soil to selectively pass through the filter material, and storing the core therein. The purpose of the present invention is to provide the elastic drain material to improve the soft ground having a corrugated core, and preventing the soil from being introduced into the elastic drain material. |
