PURPOSE:To prevent the outflow of soil to the outside of a structue by using the structure for greens-planting work, having a roughly structured interlacing layer and a sensely structured interlacing layer made of a high-strength synthetic fiber and connected in the longitudinal direction. CONSTITUTION:A structure 1 for greens-planting work of a slope is made of high-strength synthetic fibers 2 connected in the longitudinal direction of a structure 1. The high-strength synthetic fibers 2 consist of a roughly structured interlacing layer 3 and a densely structured interlacing layer 4. The preferred size of the high-strength synthetic fiber 2 is in the range of 1,000-10,000denier. The roughly structured interlacing layer 3 has a porosity range of 95-99%, and the densely structured interlacing layer 4 has a porosity range of 40-95%. The structure 1 is fixed to a slope 11 with anchors 12, and a metal net 13 is placed on the structure 1 and fixed to the slope 11 with anchors 14. Soil is sprayed onto the interlacing layer 4, and thereby the soil moves into the interlacing layer 3. The outflow of the soil to the outside of the structure 1 can thus be prevented. |
