Abstract

PURPOSE:To stabilize soil by using a pocketlike net in sprinkling a vegetation bed over a face of slope. CONSTITUTION:To sprinkle a vegetation bed over a sloping portion, a net 5 comprising supports 4 attached at predetermined intervals to continuous meshes is suspended from an anchor 2 installed at the upper portion of the slope; A hanging member 3 such as a chain hangs from the anchor 2 and the supports 4 are secured to the hanging member 3 in such a manner that the net 5 equipped with the supports 4 is sagged and that pockets 6 are formed in the horizontal direction, and the hanging member 3 or the supports 4 are held in place by means of a sub-anchor 2' and then a vegetation bed material 7 is sprinkled to grow plants. Since the pockets 6 are formed by the net 5, the vegetation bed material 7 can be sprinkled stepwise over a face 1' of slope, and so a stable vegetation bed can be constructed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for stabilizing a soil by forming a pocket net when spraying (attaching) a growth base to an inclined portion.

[0002]

2. Description of the Related Art As a conventional technique, there is a thick layer base material spraying process in which a wire mesh is attached to an inclined portion and a vegetation base material is sprayed onto the wire mesh. There is a thick net work in which a wire mesh made by weaving a wire mesh into a spring shape is attached to an inclined portion and a vegetation base material is sprayed onto the thick wire mesh. There is a method of attaching the base to the bag in advance and attaching it to the slope.

[0003]

[Problems to be Solved by the Invention] The thick layer base material spraying method is one in which a wire net is stretched and the base material is sprayed thickly to form a base. When the base material has a smooth surface or a steep slope, rainfall water is Since it directly flows down the surface, it is eroded and the foundations such as the soil are washed away and the plants decline. The smooth slopes are slippery when snowfall occurs and damage the avalanche and damage the base and plants. When a steep and smooth slope is freeze-thawed, the base freezes up and is washed away, causing plant decline. The thick net method can thicken the base with a thick net, and the stability of the base is good, but the same phenomenon as the thick layer base material spraying method occurred over time. A pocket-shaped bag is one in which a base pocket is attached in advance and is hung from the shoulder of the slope. Since it is heavy, its location is limited to a gentle slope or near a road where heavy equipment such as a crane is used. The present invention has been devised to solve such problems.
