PURPOSE:To omit the formation work of a slope with soil brought from another place by using a square flat board form of a container having an one side length of 0.5-1.5m and a height of 10-30cm, made of a flexible, water-permeable strong material. CONSTITUTION:A container 2 consisting of a bottom 5 and four peripheral edges 6 is formed of a composite material consisting of a flexible netted material, e.g., synthetic fiber ropes, and a water-permeable nonwoven fabric sheet 4 of a small mesh. The length of one side of the container is set up to 0.5-1.5m, the height is also set up to 10-30cm, and knobs 7 are provided to the four corners of the container. Soil suitable for plantation is packed to form a soil board having a weight of 100kg-1ton, and the soil boards are lifted up by a crane, etc., having a steel frame 10 provided with a hooking metal 9 and laid on a slope. By this, the need for human power can be eliminated. |
