  Next, an exterior plate 5 for the purpose of mainly applying makeup is installed on the outer peripheral side. In the present embodiment, the protruding portions 5a formed on the side surfaces of the exterior plate 5 are engaged with the engaging grooves 9a that open toward the outside of the leg portions 9 and are formed on the side surfaces facing the outside of the side wall plate 7a. The exterior plate 5 is installed so as to cover the outer peripheral side wall plate 7a by engaging the protruding portion 5a with the holding groove 7d of the pair of projected portions 7c. Thus, when each structural member is assembled, the upper surface is positioned on the substantially same horizontal plane as the upper end of the side wall portion 2 in the space 10 divided into four by the partition portion 3 in each planting portion 2. As shown, the soil (not shown) is filled, and seeds are planted on the soil, or a cut grass is placed, and then planted. Moreover, the irrigation means (not shown) which supplies liquid fertilizer and irrigation to soil and the planted plant as needed is installed, and the construction of the greening system A of this embodiment is completed.

  Here, in the conventional tree planting system, the water storage part and the planting part are each formed in a rectangular box shape of the same shape and the same size, so the transportation efficiency of the water storage part and the planting part becomes worse as the number of these installations increases. As a result, the workability deteriorated. Moreover, since the planting part is formed in the shape of a fixed box of a predetermined size in advance, for example, the soil accommodated in the planting part is increased in accordance with changes in the type of plant, and the thickness thereof is increased. There was a problem that it was not possible to respond flexibly.

Moreover, also in the planting part 2, as shown in FIG. 3, since the side wall part 7 (side wall board 7a), the baseplate part 8, and the leg part 9 are each isolate | separated and formed in flat form or rod shape, Compared with the rectangular box-shaped planting part used in the tree planting system, these components can be individually transported together with the apparent volume being reduced. Furthermore, also in the partition part 3, as shown in FIG. 7, it is comprised from the two partition plates 3a and 3b, and it is predetermined by combining each other via the fitting groove 3c formed in each partition plate 3a, 3b. Since it can be formed into a shape, the two partition plates 3a and 3b can be transported together in a separated state during transportation. Moreover, in this embodiment, since the two partition plates 3a and 3b are made into the same shape and the same size, it is not particularly necessary to sort them and can be easily combined.

  Moreover, in the tree planting system A of this embodiment, when it wants to increase the thickness of the soil accommodated in the planting part 2 according to the kind etc. of a plant, it is engaged with the engagement groove | channel 9a of the leg part 9, and can be attached or detached. The space 10 of the planting part 2 can be expanded upward by a simple operation of exchanging the side wall plate 7a with the side wall plate 7a having a large height, and flexibly corresponds to the change of the soil layer thickness. be able to. Moreover, even if the exterior plate 5 provided so as to cover the side wall plate 7a on the outer peripheral side is replaced with the exterior plate 5 having a large height, the soil is easily stored in the space defined by the exterior plate 5. The soil with a desired thickness can be formed with a simple operation.

  Moreover, in this embodiment, when rainwater (or irrigation from the irrigation means) is supplied to the greening system A, the rainwater penetrates into the soil, and a part of the rainwater is retained in the soil and used for plant growth. . On the other hand, surplus water that has passed downward without being retained in the soil flows down through the drain holes 8 a of the bottom plate 8 and is stored in the space 11 of the water storage panel 1. The surplus water stored in this way is sucked up by the water absorption zone 4 at the time of fine weather, for example, and supplied again to the soil located above to be used for plant growth. Therefore, in the tree planting system A of the present embodiment, rainwater and surplus water can be stored and supplied to the upper soil again, so that the frequency of watering by the watering means can be reduced.

  Furthermore, as shown in FIG. 2, since the side wall 1a of the water storage panel 1 is formed in a taper shape, between the side walls 1a of the adjacent water storage panels 1, the laying surface T1 of these side walls 1a and the artificial ground T is provided. Thus, a water passage 12 having a triangular cross section is defined. By defining the water passage 12, the greening system A of the present embodiment can discharge rainwater accumulated on the artificial ground T through the water passage 12.

  Moreover, in this embodiment, since the partition part 3 is provided in soil, even when external force, such as a pedestrian's treading pressure, acts after the tree planting system A is constructed, this external force is divided into partition parts. 3 can be received and supported. Thereby, it can prevent that external force acts on the side wall part 7 etc. of the planting part 2, etc., for example, and can prevent the planting system A from being damaged. Moreover, at this time, since the soil is filled in the space 10 divided into four of the planting part 2 by the partition part 3, the soil on which the external force has acted is not biased. It is also possible to hold the soil in a stable state.

  Furthermore, even when the soil is divided into four parts by the partition part 3, the roots of the planted plants and the irrigated water are divided between the divided soils through the plurality of cutout parts 3d provided in the partition plate 7a. You can go back and forth. Thereby, it becomes possible to maintain the growth of a plant in a suitable state.

  Therefore, according to the tree planting system A of the present embodiment, each component can be efficiently transported in a separated state to improve workability, and flexibly cope with changes in soil thickness. be able to. In addition, it is possible to construct the greening system A by easily assembling the constituent members configured simply, and to form a plurality of spaces 10 of the planting part 2 that accommodates soil by using the side wall plate 7a and the leg part 9 together. Therefore, it is possible to reduce the cost.

  As mentioned above, although embodiment of the tree planting system A which concerns on this invention was described, this invention is not limited to said one Embodiment, It can change suitably in the range which does not deviate from the meaning. For example, in this embodiment, the side wall 1a of the water storage panel 1 is formed in a tapered shape, so that a plurality of water storage panels 1 can be stacked while being engaged, and can be transported together in a state where the apparent volume is reduced. However, for example, a stepped portion is formed on the side wall 1a of the water storage panel 1 so that the side wall 1a on the lower end side is disposed on the inner side with respect to the side wall 1a on the upper end side, and the lower end side is parallel to the upper end side. It may be formed to extend vertically. When formed in this way, the lower end side of the water storage panel 1 is inserted from the opening 1c on the upper end side of the other water storage panel 1, and the plurality of water storage panels 1 are engaged and stacked, as in this embodiment. The apparent volume can be reduced. Therefore, a plurality of water storage panels 1 can be efficiently transported together.

  Moreover, in this embodiment, although the several water storage panels 1 were laid on the artificial ground T and the greening system A was comprised, the one planting part 2 is provided in one water storage panel 1. FIG. A greening system A may be configured. Furthermore, in this embodiment, the water storage panel 1 and the bottom plate portion 8 are each formed to have a square shape in plan view. However, the shape in plan view need not be particularly limited. It may be formed in a rectangular shape.

  Further, in the present embodiment, the partition portion 3 is provided. However, an external force such as a pedestrian's stepping pressure does not act, or even when the external force acts, for example, the side wall portion 7 is damaged or the soil is broken. When it is determined that no deviation occurs, the partition 3 is not necessarily provided. Moreover, although the partition part 3 shall be formed in the cross shape combining the two partition plates 3a and 3b, for example, a plurality of fitting grooves 3c are formed in the partition plates 3a and 3b, and three or more sheets are formed. The partition plates 3 may be combined with each other, and the partition portion 3 may be formed in a lattice shape, for example. In this case, an external force larger than that of the partition portion 3 of the present embodiment can be supported according to the number of partition plates, and the soil and the greening system A can be held more stably. In addition to this, the partition plates 3a and 3b are provided with two pairs of notch portions 3d each having a U-shaped cross section. If the notch 3d is formed so that water can go back and forth, the shape, arrangement, number, etc. of the notch 3d are not particularly limited.
