Description of the Related Art In the above-mentioned patented invention, in a greening method on a hard rock slope, a net body is closely stretched along a ground slope and a soil is to be planted on a site to be planted on the net body. While positioning the bag, holding it with the holding frame, fixing the customer bag with the holding frame to the slope via the anchor pin, leaving the planting mouth on the customer bag top surface after forming the sprayed layer around the soil bag performs mortar or concrete spraying Engineering, to perform planting in soil dressing bag through an opening in the soil dressing bag in conformity with a position of the planting栽口of soil dressing bag top The invention has been provided. By this, especially the mortar or concrete spray layer is applied only around the customer bag and the holding frame,
It does not spray on other slopes. Therefore, there is an effect that it is less time-consuming and more efficient than a full-surface spraying work on the ground surface.

である。However, in the above-mentioned patented invention, there are many places where mortar spraying cannot be performed at the construction site in the mountainous interior. In addition, the construction site in the mountainous outskirts is relatively cool, and there is no need to expect the heat insulation effect of mortar spraying. Further, since the stretched net body is heavy and has a large area on the ground surface, handling is extremely troublesome and troublesome. Also, the holding frame is often molded from expanded metal because of its shape-retaining property, so that it is heavy and bulky, and it is therefore difficult to carry it to a slope.

崩落を防止することができる。As described above, the greening method for hard rock slopes according to the present invention has the above-mentioned structure. Therefore, a vinyl chloride belt-like net for fixing a guest clay bag to the slopes is lightweight and has good workability. Applicable even when mortar spraying is not performed. That is, mortar spraying may not be possible at the construction site in the mountainous outback. In such a case, when the holding frame in the conventional patented invention is formed of expanded metal,
Due to the fact that this is exposed, rust quickly comes out and the condition is bad. In addition, in the construction site in the mountainous interior, there is a cool area, and when it is not necessary to expect the heat insulating effect by mortar spraying, it is not necessary to use the wire mesh holding frame. On the other hand, according to the present invention, greening can be carried out at an early stage by using a customer bag that is held and fixed by a vinyl chloride band-shaped net and herbs instead of mortar spraying. Furthermore, even if the wire mesh is not stretched in the conventional patent invention, a binding force is generated due to the soil spraying and rooting by the growth of herbs, thereby preventing the rocks from collapsing.
