PURPOSE:To prevent the slackening and falling of planting materials sprayed on the upper part of a water-impermeable slope by dividing the water-impermeable slope into contour lined sections by using horizontal cement mortar beams inserted with iron bars having a high bonding strength. CONSTITUTION:Fibrous composite mats 3 are laid in a contour lined manner on a water-impermeable slope 1 by means of concrete nails 4. Then, anchor bolts 5 are driven at equal intervals along the lower ends of the mats 3 in such a way that the heads of the anchor bolts 5 are exposed about 15cm or more from the mats 3. Then, the heads of the anchor bolts 5 are connected by iron bars 6 and on the upside of the part, drain pipes 7 are inserted at equal intervals into the mats 3. Then, cement mortar is sprayed on the drain pipes 7, the iron bars 6, and anchor bolts 5 in such a way as to cover all of them. And so, a planting material 10 consisting of soil, fertilizer, seeds, etc, is sprayed on the slope 1 divided by cross beams 2 on cotrour lines. |
