PURPOSE:To prevent the dropping of replace soil from slope by a method in which a preventor for dropping of replace soil, having a high water absorbability and a high water holding capacity, is inserted into a net for holding replace soil, laid on the slope, and swelled with water, and replace soil mixed with weed seeds, etc., is sprayed onto the net. CONSTITUTION:A net 1 is laid through anchors 6 on a slope 5, and a replace soil droppage preventor 3 made of a material having a high water absorbability and a high water holding capacity is attached through spaces 2' to the net 1. After the preventor 3 is swelled with water, replace soil 8 mixed with seeds 7 of weeds, etc., is sprayed onto the net 1. The droppage of large amounts of the replace soil 8 can thus be prevented by means of the preventor 3 so swelled, and water necessary for growth of the seeds 7 can also be held. |
