The planting area 2 is configured by arranging a plurality of planting containers 2a. This is the minimum requirement for the planting area 2.
In the illustrated example, each planting container 2a has a bottom portion 2b, a side portion 2c surrounding the bottom portion 2b, and an open top portion 2d. Between the open upper portion 2d and the bottom portion 2b of the planting container 2a, a partition wall 2e is formed to divide the inside of the planting container 2a into upper and lower parts. A culture medium M is held on the upper side of this partition wall 2e. The partition wall 2e is configured to allow passage of a liquid (water, water containing fertilizer, rainwater when the planting area 2 is provided outdoors) used for growing plants. A surplus of the liquid supplied to the medium M and used for plant growth passes through the partition wall 2e and is stored below the partition wall 2e.
In the illustrated example, the planting container 2a has a square shape in plan view. In the illustrated example, in the water flow direction x from the water surface WU to the water surface WD of the greening target surface, the lower side portion 2c of the planting container 2a positioned on the water surface WU side is positioned on the water surface WD side. One container row 2f composed of a plurality of planting containers 2a is configured so as to face the upper side surface portion 2c of the planting container 2a, and the adjacent planting containers 2a are arranged in the direction orthogonal to the water flow direction x. A planting area 2 is formed by a plurality of planting containers 2a by arranging a plurality of container rows 2f such that the side portions of the container rows 2f along the water flow direction x face each other.

Further, in FIG. 1, reference numeral 8 denotes a supply pipe for supplying the liquid by dripping or the like to the culture medium M of each planting container 2a constituting the planting area 2 by opening the valve means.

The guide channel structure 3 is configured to guide the liquid, which has passed through the lower portion 2h of the planting container 2a in the planting area 2 and is used for plant growth, to the drainage side. This is the minimum requirement for the guide channel structure 3 .
In the illustrated example, each of the container rows 2f is provided with two tubular guide flow passage structures 3 each having a pipe axis along the water flow direction x. Each guide channel structure 3 is located under the partition wall 2e of the planting container 2a, and has a space between its upper end 3a and the partition wall 2e, and its lower end 3b is attached to the bottom surface portion 2b of the planting container 2a. They are arranged so as to be close to each other.
Further, each guide channel structure 3 is configured by connecting guide pipe elements 3c positioned in each planting container 2a constituting one container row 2f via a joint member 3d. there is In the illustrated example, one container row 2f consists of three planting containers 2a, and therefore one guide channel structure 3 comprises three guide pipe elements 3c and two joint bodies 3d. The underwater WU side pipe end of the guide pipe element 3c positioned on the underwater WD side is connected to the underwater WD side pipe end of the guide pipe element 3c positioned on the underwater WU side via a joint body 3d. The joint body 3d has a pipe end 3e on the underwater WU side, a pipe end 3f on the underwater WD side, and a branch pipe 3g projecting upward from the upper end of the pipe between them. A guide pipe element 3c positioned on the underwater WU side is connected to the pipe end 3e on the underwater WU side of the joint body 3d, and a guide pipe positioned on the underwater WD side is connected to the pipe end 3f on the underwater WD side of the joint body 3d. Element 3c is connected (see FIG. 2).
When the liquid level below the partition wall 2e of the planting container 2a reaches the upper end of the branch pipe 3g of the joint body 3d, the surplus liquid flows into the guide channel structure 3 via the joint body 3d. It has become.
In the illustrated example, the pipe end on the side of the underwater WD of the guide pipe element 3c in the planting container 2a positioned most in the underwater WD in one container row 2f is the first end of the connecting member 5, which will be described later. The surplus of the liquid flows into the first pipe portion 5a from the receiving portion 5h formed in the first pipe portion 5a of the planting container 2a located at the lowest position while being connected to the pipe portion 5a. It's like
Accordingly, in the illustrated example, the guide pipe element 3c positioned at the most underwater WD, which constitutes one guide channel structure 3, is not provided with the joint body 3d as described above.

The drainage channel structure 4 is connected to the drainage side of the guide channel structure 3 (the terminal on the side of the underwater WD) via a connection member 5 . This is the minimum requirement for the drainage channel structure 4 .
In the illustrated example, the drain channel structure 4 includes a drain pipe element 4a that connects the later-described connecting members 5 of the adjacent container rows 2f, and drains the surplus liquid that has flowed into the drain pipe element 4a. 6 (FIG. 1) or alternatively from an extension pipe element 4b (FIG. 10) leading to the reflux means 9. FIG.

The connection member 5 includes a first pipe portion 5a connected to the guide channel structure 3 and a second pipe portion 5a having a larger pipe diameter than the first pipe portion 5a connected to the drainage channel structure 4. The pipe portion 5c is placed on the side portion 5e of the second pipe portion 5c so that the lower end 5b of the first pipe portion 5a and the lower end 5d of the second pipe portion 5c are positioned on the same imaginary plane. It has the structure which connected one pipe end of the said 1st pipe part 5a. At the same time, a vent portion 5g is formed on the upper end 5f side of the second pipe portion 5c. This is the minimum requirement for the connecting member 5 .

In this embodiment, at least part of the first pipe portion 5a of the connection member 5 is positioned inside the planting container 2a, The liquid receiving portion 5h is formed on the upper end side of the portion positioned inside the planting container 2a.
More specifically, the vent portion 5g is a slot elongated in the axial direction of the second pipe portion 5c.
Moreover, the connection member 5 connects the two first pipe portions 5a arranged in parallel and the one second pipe portion 5c to the second pipe portion 5c with respect to the pipe axis of the first pipe portion 5a. The tube axis 5i (see FIG. 3) of the portion 5c is integrated so as to be perpendicular to each other.

In the illustrated example, both the first pipe portion 5a and the second pipe portion 5c have a circular cross section perpendicular to the pipe axis. In addition, both the inner and outer diameters of the second pipe portion 5c are larger than those of the first pipe portion 5a.

The upper end of the first pipe portion 5a is positioned substantially at the same level as the pipe axis 5i of the second pipe portion 5c, slightly above or below it, and the pipe end on the underwater WD side is It communicates and integrates with the side portion 5e of the second pipe portion 5c.
Further, the first pipe portion 5a is connected to the guide pipe element 3c positioned closest to the underwater WD side at its pipe end on the water WU side.
A branch pipe 5j projecting upward from the upper end of the first pipe portion 5a is provided between the pipe end on the water WU side and the pipe end on the underwater WD side of the first pipe portion 5a. This branch pipe 5j functions as the receiving portion 5h.

In addition, the connecting member 5 has two first pipe portions 5a, and each of the two guide flow path forming bodies 3 provided in one container row 2f is connected to the corresponding first pipe portion 5a. It's like

Moreover, the connecting member 5 is arranged so that the second pipe portion 5c is positioned outside the planting container 2a positioned at the lowest WD in one container row 2f. One end of the second pipe portion 5c of one connecting member 5 of the adjacent container rows 2f and one end of the second pipe portion 5c of the other connecting member 5 are connected by the drain pipe element 4a. In the example shown in FIG. 1, the other end of the second pipe portion 5c of the connecting member 5 connected to the rightmost container row 2f and the connecting member connected to the leftmost container row 2f 5 and the other end of the second pipe portion 5c are connected to the extension pipe element 4b. The lower ends of the thus connected drain pipe element 4a and extension pipe element 4b are positioned substantially at the same level as the lower end 5d of the second pipe portion 5c.

Since the second pipe portion 5c has a larger pipe diameter than the first pipe portion 5a, as shown in FIG. 11, the lower end 5b of the first pipe portion 5a is positioned above the lower end 5d of the second pipe portion 5c. In this way, a portion 100 of the second tube portion 5c located below the lower end 5b of the first tube portion 5a can be used to receive the surplus of the liquid. However, in this case, there is no choice but to form a pedestal portion or the like indicated by reference numeral 101 in FIG. 11 under the lower end 5b of the first pipe portion 5a.

In this embodiment, the first pipe portion 5a is connected to the second pipe portion 5c having a larger pipe diameter than the first pipe portion 5a, the lower end 5b of the first pipe portion 5a and the second pipe portion 5c. and the lower end 5d thereof are connected so as to be positioned on the same imaginary plane.
On the other hand, if this is done, there is no point 100 (see FIG. 11) positioned below the lower end 5b of the first pipe portion 5a in the second pipe portion 5c, so that the liquid level in the second pipe portion 5c rises to the second level. It becomes easier to reach the upper end of the first tube portion 5a, and the gas phase portion of the second tube portion 5c and the gas phase portion of the first tube portion 5a are likely to be separated. Internal pressure rises easily. An increase in the internal pressure of the second pipe portion 5c hinders smooth drainage and can cause backflow to the first pipe portion 5a side. This causes problems such as disturbing the planting state and causing the culture medium M to flow out of the container. However, in this embodiment, the gas phase in the second tube portion 5c can be made to always match the atmospheric pressure by means of the ventilation portion 5g, thereby preventing such problems as much as possible. be able to. Also, in the case where the planting area 2 is provided on the roof or the like, when rainfall exceeds expectations, overflow from the ventilation part 5g is caused to prevent overflow from occurring on the planting area 2 side. can do.

FIG. 10 shows a greening system 1 provided with circulation means 9 for causing the liquid obtained from the drainage channel structure 4 to circulate to the planting container 2a. In FIG. 10, reference numeral 9a denotes known pump means controlled by a control means (not shown), reference numeral 9b denotes known valve means controlled by an unillustrated control means, and reference numeral 9c connects the pump means 9a and the valve means 9b. Reference numeral 9d is a supply pipe for supplying the liquid by dropping it to the culture medium M of each planting container 2a constituting the planting area 2 by opening the valve means 9b. By operating the pump means 9a and the valve means 9b to supply the liquid in the drainage channel structure 4 to the culture medium M from the supply pipe 9d at predetermined intervals, the liquid is circulated. It becomes possible to grow plants.

It goes without saying that the present invention is not limited to the embodiments described above, but includes all embodiments capable of achieving the objects of the present invention.
