DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply system for supplying water to a plant cultivation unit group formed by laying a plurality of plant cultivation units each having a plant cultivation container mounted on a water storage tank.

[0002]

2. Description of the Related Art Although urban areas in modern society lack natural resources, greening measures are being implemented in urban areas in order to compensate for the natural insufficiency in response to human needs for nature.
Such a greening measure is performed by artificially greening the roof of a building, a veranda, a terrace, an event venue, and the like, and specifically, for example, is mounted on a floor as disclosed in Japanese Utility Model Publication No. 1-25582. A frame plate is erected along the periphery of a flat inner bottom plate that can be placed, and greening is achieved using a block box or the like in which turf is planted.

[0003] However, the technology relating to the block box does not disclose water supply at all. As a general method, a method of supplying water manually from the upper portion of the frame body is considered, and such water supply requires a great deal of labor. Had occurred.

[0004] In order to solve the above-mentioned problem, a technique of supplying water to plants from a water source such as a water supply by a water supply pipe has been proposed. For example, Japanese Patent Application Laid-Open No. 10-164899 discloses a technique of storing water under a cultivation tank filled with a growing material. Regarding the bottom-flush type planter provided with the tank, a water supply port on the upstream side and an overflow port on the downstream side of the water storage tank are provided, and a plurality of water storage chambers are formed by partitioning the water supply side and the overflow port side with a partition plate. In addition, a technique is disclosed in which an overflow section is provided at the upper end of the partition plate to reduce the water level difference between the water storage chambers.

[0005]

However, in the technique relating to the above-mentioned planter, a water supply port is provided for each water storage tank, and water supply pipes are required by the number of the water supply ports, and a work of connecting the water supply pipe and the water supply port is required. It is necessary and requires a great deal of cost and labor for construction.

[0006] Further, the water supply pipe branched from the water source is not suitable for a wide range of greening measures since the water pressure decreases as the number of branches increases, and the water source must be increased when greening is performed over a wide range. That was the problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an inexpensive water supply system that reduces labor and cost for construction and enables good water supply to a wide range of green areas. The purpose is to:

[0008]

According to the water supply system of the present invention, a plant cultivation unit group is formed by laying a plurality of plant cultivation units each having a plant cultivation container mounted on a water storage tank. In a water supply system for supplying water through a pipe, a flow path for restricting a flow direction to one direction is formed in the water storage tank.

[0009] It is preferable that the water storage tank is linked by a linking portion, and that the linking portion is formed integrally with at least an upper end of one side wall of the water storage tank. In addition, a space may be formed on the water storage tank of the plant cultivation unit group and between the plant cultivation containers. Further, the plant cultivation container may be provided with an inward dent at least on one side wall.

The water supply system is characterized in that the water flow path is formed by a concave groove formed at an upper end of a side wall of the water storage tank.

The water supply system is characterized in that the water storage tanks are linked to each other by a link provided at an upper end of a side wall at a predetermined position, and the concave groove is formed in the link.

Further, the water supply system is characterized in that the water supply pipe is disposed so as to be orthogonal to the flowing water direction. The water supply pipe is preferably a porous pipe.

[0013] In the water supply system, a space is formed on the water storage tank and between the plant cultivation units.
A water supply pipe is arranged in the space.
That is, the water supply pipe is arranged in an arbitrary space perpendicular to the flowing water direction.

Further, the water supply system may further comprise an indicator for instructing a laying direction in the water tank, and laying the water tank in accordance with the instructing part to form the water flow path for regulating the flowing direction to one direction. It is characterized by.

[0015]

Next, the operation will be described.

For example, in the water supply system of the present invention, a water supply system for laying a plurality of plant cultivation units each having a plant cultivation container mounted on a water storage tank to form a plant cultivation unit group and supplying water to the plant cultivation unit group is described below. A water flow path that regulates the flow direction between the storage tanks in only one direction is formed,
By arranging the water supply pipes orthogonally to the flowing water direction, at least one water supply pipe is sufficient, and the complexity of the work of arranging the water supply pipes can be reduced, and the cost can be reduced. Becomes

[0017] Further, when the water storage tank is laid, an indicator for instructing the laying direction of the water storage tank is provided in the water storage tank in order to restrict at least the flow direction between the water storage tanks in one direction, so that the water storage tank can be constructed at the time of construction. The operator only needs to perform the operation according to the instruction section, and the complexity at the time of the operation can be reduced.

In addition, by connecting the water storage tank with the linking part,
The planting unit group is not separated, and the green area can be maintained.

Further, since the linking portion is formed integrally with at least the upper end of one side wall of the water storage tank, the number of components at the time of construction can be reduced, and the construction work can be facilitated.

Further, since the water flow path is formed by a concave groove formed at the upper end of the side wall of the water storage tank, there is no need to connect a water flow pipe or the like, the number of parts is reduced, and the construction work is easier. Become In this case, even if there are partial protrusions on the laying surface, as long as the height of the concave groove does not exceed the height of the side wall, the flowing water direction is regulated in one direction, so that water does not detour all Will be filled with water.

Further, by forming a space on the water storage tank and between the plant cultivation containers, the air permeability in the plant cultivation unit group is improved, and rooting is prevented. Further, by arranging the water supply pipe in an arbitrary space orthogonal to the flowing water path, excellent appearance design can be obtained, and the work of arranging the water supply pipe becomes easy. Further, by making the water supply pipe a porous pipe, the water supply / irrigation system of the present invention can be more effectively used.

Further, the plant cultivation container has an inward recess formed on at least one side wall, so that a water supply pipe can be disposed in the inward recess. Since it can be held from the upper part and can be held from the lower part by the water storage tank, the support fitting of the water supply pipe becomes unnecessary, the number of parts is further reduced, and the construction work is facilitated.

Next, the water storage tank 10 and the plant cultivation container 2
A state in which the plant cultivation units made of zero are laid on the laying surface in association with each other will be described. 14 and 15 show the linked state of the plant cultivation container and the water storage tank, FIG. 14 is a partially enlarged cross-sectional view showing a space part in the present invention, and FIG. 15 is a state in which a water supply pipe is arranged in the space part in the present invention. FIG.

When connecting plant cultivation units in series,
The water storage tanks 10 are connected to each other by the wide link 13a and the narrow link 13
b, the positioning concave portion 26a is fitted to the positioning convex portion 11a on the water storage tank 10, the plant cultivation container 20 is placed, and the container linking convex portion 27a and the concave portion 27b are engaged and connected. At this time, the space 50 is formed on the water storage tank 10 and between the plant cultivation container side walls 22 because the inward recess 22a is formed in the plant cultivation container side wall 22. A water supply pipe 60 is arranged in this space 50,
The water supply pipe 60 is not visible from the upper part of the plant cultivation container 20 and the decorativeness is improved.

The water supply pipe 60 does not need to be provided with a water supply pipe support bracket, and the vertical and horizontal movement of the water supply pipe 60 can be held by the side wall 22 of the plant cultivation container 20 and the water storage tank 10. As the water supply pipe 60, a porous pipe is suitable, and various pipes such as a perforated pipe, a seepage pipe, and a drip type drip pipe can be considered.

Next, the water supply system of the present invention will be described. FIGS. 17 to 20 and 22 show a state in which a plurality of water tanks 10 or plant cultivation containers 20 are laid.
7 is a partially enlarged plan view showing a state where a water supply pipe is arranged in a water tank group in the present invention, FIG. 18 is a plan view showing a state where a plant cultivation container in which plants are planted is placed in FIG. 17, and FIG. FIG. 20 is a partially enlarged plan view showing a planting unit group of the present invention when the greening area is completed, FIG. 20 is a partially enlarged sectional view showing a plant cultivation unit group of the present invention, and FIG. 22 is a plan view showing a construction example of a water supply system of the present invention.

In the figure, a water supply pipe 60 is connected to a main pipe 6 from a water source.
0a is disposed, and a plurality of water supply pipes 60 are provided from the main pipe 60a.
Are branched via a branching device 61. The water supply from the water source may be automatically performed, and the water supply may be started at a predetermined time via an electromagnetic valve or the like, and may be stopped after a predetermined time elapses.

Here, the laying surface is inclined from A to B shown in FIG. 22, and a plurality of water tanks 10 are laid such that the indicating portions 11b face the B direction. The water tank 10 laid in this way
The groove 14 is configured so that water can flow in a direction from the inclination direction A to the direction B, and the water supply pipe 60 is arranged from the direction C to the direction A. By arranging the water supply pipe 60 from C to A, water flows from a plurality of holes (not shown) provided in the water supply pipe 60 onto the water storage tank 10, and water overflows in the water storage tank 10. Is configured to flow into another water storage tank 10 along the concave groove 14. The water supply pipe 6
It goes without saying that the arrangement of 0 may be A to C.

It is desirable to arrange a plurality of water supply pipes 60 at appropriate intervals from the upstream, but if at least one water supply pipe 60 is provided at the most upstream side, water can be uniformly supplied to all the water storage tanks 10. it can. That is, when water is supplied from the water supply pipe 60 to the upstream water storage tank 10 and the water content in the upstream water storage tank 10 increases, the water naturally overflows from the concave groove 14 and is supplied to the next water storage tank 10. Therefore, the water is distributed to all the water tanks 10 and the water up to the water level of the concave groove 14 is held in the water tank 10, so that water can be uniformly supplied to all the water tanks 10. It becomes possible. The water in the water tank 10 at the most downstream of the water tank group overflows from the concave groove 14 and flows to the laying surface, so that it is possible to discharge surplus water in the water tank 10 to the outside, and to remove roots of plants. This can be prevented.

For example, in FIG. 22, the water supplied from the water supply pipe M to the water storage tank D is stored in the water storage tank D. When the water is full, the water flows from the concave groove 14 to the water storage tank E, and then flows to the water storage tank F. The water supplied to the water storage tank G is stored in the water storage tank G, and when the water is full, the water is supplied from the concave groove 14 to the water storage tank H.
The water supplied to the water storage tank J is then stored in the water storage tank J. When the water is full, the water flows from the concave groove 14 to the water storage tank K, and then the water storage tank L
The water will flow.

By adopting the above configuration, for example, even when there is a projection or the like on the laying surface on which the water storage tank E is laid, the flow direction is one direction (from the water storage tank D to the water storage tank F via the water storage tank E, etc.). ), Water from the water storage tank D flows to the water storage tank E without detouring to the water storage tanks G, J, etc.
After that, it flows out to the water storage tank F. By the above, in the water storage tank E,
Alternatively, the problem that water is not supplied into the water storage tank F (moisture does not spread at the time of water supply) does not occur.

When a plurality of the water supply pipes 60 are arranged, it is desirable to supply water sequentially for each block by a relay method, thereby preventing a decrease in water pressure due to water supply and supplying water uniformly to all blocks. Becomes possible.

When the plant cultivation containers 20 are laid on the water storage tank 10 to form a plant cultivation unit group as described above, some gaps are formed between the plant cultivation containers 20. Distribution becomes possible, and ventilation of the lower part and upper part of the plant cultivation container 20 is enabled. In addition, by planting a plant, it becomes difficult to visually observe the gap from above as the plant grows, and the gap does not become a lack of decorativeness.

Further, the decorativeness can be improved by surrounding the above-mentioned plant cultivation unit group with a curb 70 or the like from the outer periphery as shown in FIG. At this time, for example, the inward concave portion 2 of the side wall 22 of the plant cultivation container 20 in the curb 70 or on the water tank 10 and in contact with the curb 70
If the main pipe 60a is arranged in the space between the 2a and the curb 70, the decorativeness is further improved.

The plate 71 is placed on the plant cultivation container 20.
By placing the like, various layouts can be enjoyed and the decorativeness can be further improved. As the material of the plate member 71, various materials such as wooden, stone, iron, and plastic can be considered. In addition, lights, seats on a support plate, desks, clock towers, handrails, supports,
It is also possible to fix a support or the like used for a playground equipment or the like, so that a more diverse layout can be enjoyed.

As shown in FIG. 23 as a modification of the water storage tank, when the four water storage tanks 10 are formed as one unit partitioned by the partition portion 12a, the laying operation becomes easier. In this case, it is sufficient to provide only the concave groove 14 without providing the linking portion 13 between the water storage tanks 10 in the unit, and the four water storage tanks 10 can be laid in a single laying operation. It is possible to reduce the time and labor spent for work. Similarly, the plant cultivation container 20 has a 4
One plant cultivation container 20 may be configured as one unit and placed on the water storage tank 10, so that the time and labor spent on the laying operation can be further reduced.

Although the water supply system of the present invention has been described above, the present invention is not limited to the above embodiment, and the following modifications and expansions can be made. For example, the shapes and configurations of the plant cultivation container 20 and the water tank 10 are all encompassed within the scope of the present invention. In particular, in the embodiment, a substantially rectangular plant cultivation container 20 is used.
