[0014]

In any of the first to sixth aspects of the invention, since a rock cutting machine is used to form a plurality of steps in a stepwise manner that are continuous in a substantially contour line on the rock slope, Rainwater will be stored on the steps. Therefore, the damage of dryness can be prevented. Further, since the vegetation base material is sprayed on the rock slope, it is possible to secure aesthetics by greening the entire surface.

Further, since the bedrock cutting machine for cutting the bedrock by rotating the drum provided with a plurality of cutting bits is used, the excavation work of the bedrock slope can be performed more accurately and efficiently than the static blasting method. Can be done That is, it can be applied to a wide range of rocks from soft rocks to hard rocks and can perform efficient cutting.For example, the cross slope and height of the cutting surface in rocks can be automatically determined by the level controller. Since it can be maintained, high precision cutting can be performed.

In the invention according to claim 1, the bag body can supply the fertilizer nutrients to the vegetation base material, and since the bag body is flexible at least in the state where the fertilizer is stored, even if it is on the upper surface of the step portion. Even if there is an uneven surface, the bag fits into the uneven surface, which can improve the workability and prevent the vegetation base material from spilling between the bag and the uneven surface. It is possible to avoid bad growth of trees and the generation of fallen trees due to wind. Moreover, the construction method using this bag body is simply installed on the upper surface of the step portion, so that workability is also good in this respect. In addition, this bag can store rainwater, therefore, in addition to the advantage that rainwater can be stored in the steps, the vegetation base material is more difficult to be affected by drying, and death due to lack of water is prevented. Can be achieved. Even if it is not necessary to plant trees, the vegetation base material mixed with vegetation seeds is sprayed onto the rock slope to spray the vegetation base material onto the rock slope. It can be secured (see FIG. 10 described later).

According to the second aspect of the present invention, the planted tree planted on the stepped portion provided with the bag body grows along the stepped portion without the roots and stems thereof being damaged by the dryness. Therefore, it will not be damaged by fallen trees. Further, since the vegetation base material is sprayed after planting, it is possible to advantageously ensure the aesthetic appearance by greening the entire surface (see FIG. 9 described later).

In the invention according to claim 3, since the net is stretched over the entire rock slope including the bag, it is possible to easily prevent the planting tree and the vegetation base material as the spraying material from being washed away. The planted tree and the vegetation base material are more difficult to be affected by the drying, and death due to lack of water can be prevented. When the embankment material serving as a growth base is sprayed at the same time as the vegetation base material, the net makes it easy to prevent not only the vegetation base material but also the embankment material from being washed away, and the growth base itself including the rock slope. Can be well protected. Also,
If vegetation seeds are also included in the bag, it is possible to secure aesthetics by further greening the entire surface. Moreover, if this bag body is installed at the front end portion of the step portion, the front end portion can be stabilized more than anything, and it can contribute to the stable maintenance of the slope surface. Therefore, in the invention according to claim 3, the most preferable rock slope vegetation construction method, which is an object of the present invention, is to reliably grow a tree on the rock slope and to stably maintain the slope surface and greening with vegetation at the same time. Can be provided (see FIG. 1 described later).

In the invention according to claim 4, even when a planting tree is not planted, the vegetation base material mixed with the vegetation seeds can be sprayed on the slope of the bedrock to ensure the aesthetic appearance by greening the entire surface. Also, when the embankment material that serves as a growth base is sprayed at the same time as the vegetation base material, not only the vegetation base material,
It is also possible to prevent the embankment material from being washed away. That is, despite having no planted tree, the vegetation seeds germinate and grow, so that the stem and leaves of the vegetation, the root system, etc. prevent the embankment material and the vegetation base material from running away and grow. This keeps the water retention of the vegetation base and prevents it from drying. Therefore, in the invention according to claim 4, it is possible to provide a preferable rock slope vegetation method capable of stably maintaining the slope surface and greening with vegetation (see FIG. 7 described later).
