PURPOSE:To simply build up a slope frame having draining property according to geographical features by a method in which a formwork for slope frame is formed of a set of two long water-permeable materials, the formwork is set on sloped ground, and concrete is placed into the space between the water-permeable materials. CONSTITUTION:Long water-permeable materials 1, each of which is formed of an assemblage of many fibrous materials, are set in a set of two materials 1 at a given interval in parallel on a slope 2. A set of two water-permeable materials 1 are laid at a given interval in parallel crossingly to the materials 1 already laid to build up a formwork for a slope frame. Concrete 4 is then placed into the space between the water-permeable materials 1 to form a slope frame. The slope frame can thus be constructed according to geographic features without the use of custom-made formwork, and its draining property can be improved. |
