DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sandbag and a greening method for greening a steep slope including hard rock, soft rock, hard soil, and the like, and more particularly, to a steep slope that has been considered impossible to green. The present invention relates to a soilbag for planting and a greening method for contributing to landscape improvement and environmental preservation by greening with trees mainly composed of trees.

[0002]

2. Description of the Related Art Conventionally, in order to vegetate a "slope surface" of hard rock, soft rock, hard soil, etc., since there is little soil for planting in the vicinity thereof, a sandbag for planting is sometimes used. there were.
In order to plant a seedling with respect to the planting sandbag, there has been a method in which a cut is made on the surface side of the sandbag and the seedling is planted there.

However, when a planting sandbag is installed on a slope and planting is performed on the slope, the packed sand flows out of the cut formed on the surface side of the sandbag for planting, and this cut is removed. The sandbag was damaged as a trigger,
There was a problem that the growth base material packed in the sandbag spilled out, which caused the planted trees to decline.

[0004] Also, a cut is made in the surface of the sandbag,
In the method of planting seedlings there, weed seeds enter the sandbag and grow from the cuts made on the surface side of the sandbag, so that the planted tree planted under the angle is pressured by this weed (weed is the planted tree). This causes the problem that the planted tree is decayed due to absorption of nutrients for the purpose, which hinders the growth of the planted tree.

[0005] In order to prevent the planted tree from being pressed by a weed seed that has invaded from the periphery and declining, a method of covering the periphery of the planted tree with straw or the like on a flat land, that is, mulching The way to do it is taken.
However, if such a mulching method is to be performed on sandbags on steep slopes such as hard rocks, soft rocks, and hard soils, mulching materials such as straws are to be used by using a skewer or the like. Must be fixed on sandbags. Such work is very costly when the slope to be constructed is steeply sloped, since it must be carried out while being carried on or prevented from falling on the steeply sloped slope. In addition, it is not possible to say that fixing the mulching material with a blind eye is sufficient to fix it, and as a result, it has been impossible until now to apply greening to steep slopes.

[0006] The inventors of the present invention have argued that, when arranging sandbags on steep slopes such as hard rock, soft rock and hard soil and planting them, how can the construction be easily performed? As a result of various studies, the present invention has been completed.

[0007]
