Has a function of suppressing the retention. For example, in addition to general soil, gravel and various wastes are granulated, or natural and high molecular water-absorbing materials are mixed.
Moreover, you may provide the proof strength with respect to the external force which the staircase structure 1 receives, for example, a pedestrian, a mounted object, etc. by including the granular material which has a buffer function in the vegetation base 31. FIG.

Nutritionally, poor nutrition is desirable. The term “poor nutrition” as used in the present invention does not mean the nutritional deficiency directly linked to the death of the plant 32. For example, it is an inorganic-based base mixed with a mineral ion substance in a well-balanced manner, suppressing the growth of the plant 32 and growing for a long time. It means the base state of the nature to be made.
Moreover, a water retention material may be mixed in the vegetation base 30 as needed.

  In the present embodiment, a case where a vegetation mat (not shown) is used for installation of the plant 32 will be described, but it goes without saying that the planting base 40 may be directly planted.

  The vegetation mat is grown thinly over a long period of time regardless of the house or alley. The plant 32 is easy to grow, and can be reliably vegetated by combining different types of plants 32. There are advantages such as being able to select a plant according to the installation site.

  The plant 32 is vegetated by combining any one or a plurality of known plants such as herbs, woods, and bamboos, and is preferably a wild grass, ivy plant, moss or the like that can cope with poor nutrition and harsh environments. .

<4> Manufacturing method of staircase structure The staircase structure 1 is manufactured and stocked in a place with a different growth environment from the installation site.
The manufacturing method of the staircase structure 1 will be described. First, a vegetation mat having a shape suitable for the side surface 302 is accommodated in the box 30 in the multifaceted green body 3 in a vertical direction, and the vegetation base 31 is placed inside the vegetation base 31. throw into.
The vegetation planned surface is applied to the exposed surface of the multifaceted green body 3 according to the arrangement form of the multifaceted green body 3, and the nonexposed surface is provided with a sheet (not shown) for preventing base outflow inside the box 30. Arrange it.
The combination of the plants 32 that green the side surfaces 302 of the box 30 may be a combination of the same kind of plants or a combination of different kinds of plants.
Moreover, the upper surface of the box 30 is vegetated with plants 32 or nothing.
Thereby, the staircase structure 1 in which the plants 32 are three-dimensionally grown on the plurality of surfaces of the box 30 of the multifaceted green body 3 is obtained.

<5> Construction of staircase structure In the present invention, the construction is completed by simply loading the prefabricated staircase structure 1 onto a truck or the like, carrying it to the planned installation site, and installing it.

At this time, as shown in FIG. 4, a plurality of staircase structures 1 are continuously installed on the slope by hooking the bottom plate 2 on the bottom plate 2 of the upper staircase structure 1. It is possible.
Moreover, the staircase structure 1 may fix the slope A and the baseplate 2 of a grounding location with the anchor etc. which are not shown in figure.

<6> Characteristics of the staircase structure Since the multifaceted green bodies 3 constituting the staircase structure 1 are replanted to the eutrophic vegetation base 31, the root system of the plant 32 gradually enters the vegetation base 31, and the plant 32 grows slowly over time based on the eutrophic vegetation base 31.
Because the poorly vegetated vegetation base 31 is excellent in water retention due to rainfall and initial watering, no artificial watering is required, and because the plant 32 is adapted to the poorly vegetative base 31, no fertilization is required. The plant 32 can continue to live for a long period of time without special maintenance of the growth environment.
Thus, the multi-sided green body 3 is carried in and installed in advance under a favorable environment, and by selecting a plant that can withstand a harsh environment, the probability that the plant 32 will die is reduced.

  Moreover, since the staircase structure 1 according to the present invention is formed of an aggregate of a plurality of multi-sided greening bodies 20, the footsteps are not slippery with respect to pedestrians, and a greening landscape by vegetation of plants 21 is also possible. .

In addition, since the staircase structure 1 is formed not only on the upper surface but also on a plurality of side surfaces as greening surfaces, the greening area is significantly superior to the installation area. Therefore, it is superior in terms of the CO ₂ reduction effect and the warming phenomenon suppression effect as compared to the case of greening on a plane.

<7> Other Embodiments The above describes the case where the staircase structure 1 is configured by an assembly of the multi-faceted greening bodies 3 in which the vegetation base 31 is housed in the box 30 and greened. There is a case where the staircase structure is configured only by the polyhedron not applied, or the staircase structure 1 is configured by using the polyhedral greening body 3 and the polyhedron together.
Even if a polyhedron that does not green as in this embodiment is used, it is lighter than the conventional staircase structure, and it is not necessary to level the slope A of the installation location. The overall construction cost can be reduced.
