Background art

Patent Literatures 1 to 3 are known literature relating to a greening structure or a greening facility in which a planting part capable of cultivating plants is provided above a water storage part or a water holding part and which effectively uses rainwater. Patent Document 1 (Japanese Unexamined Patent Publication No. 2000-20053) discloses that a plant cultivation container having an upper opening provided with a water absorbing portion from the bottom to the outside is placed in a water storage tank and plant cultivation is performed. A plant cultivation unit that forms a water storage space between the bottom of the container and the bottom of the water storage tank, forms an opening near the upper part of the water storage space, and allows rainwater to pass through the plant breeding material of the container 2 and conduct water into the water storage space. It has been disclosed.

Patent Document 2 (Japanese Unexamined Patent Application Publication No. 11-1989 / 29) discloses a cultivation container configured by stacking an upper container containing artificial soil in a lower container storing water at a certain water level. Are laid on the rooftop, and each lower container is connected and connected by a connecting pipe, and a water tap is connected and connected to each lowermost container on the upstream side, and the water of the lower container is sucked up by capillarity into the artificial soil of the upper container. There is disclosed a rooftop greening apparatus provided with a water wicking member for supplying rainwater, in which the rainwater accumulates in a lower container via the water wicking member when the moisture in the artificial soil becomes saturated.

In Patent Document 3 (Japanese Patent Application Laid-Open No. Hei 9-248080), a planting space having a predetermined shape is defined by an outer peripheral wall, and a planting space is formed in an upper layer, and rainwater is collected in a lower layer. A water storage tank for storing water, a water-permeable filter at the boundary between the two layers, and a water supply member that supplies water from the water storage tank to the soil of the planting space by capillary action are installed, and rainwater is planted in the planting space. A rainwater storage type flowerbed facility provided with a water collecting groove directly leading to a water storage tank is disclosed. In addition, Patent Document 4 (Japanese Patent Application Laid-Open No. 2001-698559) discloses a pair of planting containers.

Disclosure of the invention

However, the techniques of Patent Documents 1 and 2 disperse rainwater into plant cultivation material such as soil in a plant cultivation container when rainfall occurs, and guide rainwater to a water storage tank via the plant cultivation material. When many plants are planted in the plant cultivation container or when there is a large amount of rainfall, most of the rainwater that cannot be compensated for by the penetration into the plant cultivation material flows over the plant cultivation material and falls between the plant cultivation containers. The rainwater cannot be guided to the water storage tank and is discharged out of the greening facilities.Therefore, it is difficult to secure a large amount of rainwater and use it effectively for planting. is there. Therefore, it is necessary to separately water irrigation in order to plant the plants well, which leads to huge water costs.

In addition, the technology of Patent Document 3 directly guides rainwater from a planting space to a water storage tank through a catchment ditch, so that it is possible to secure more rainwater and use it effectively for planting. In addition, various components and work are required to separately provide a water collecting groove, which is expensive. In addition, when the water collecting groove is installed near one side wall, it is necessary to install the water collecting groove on the low slope side in consideration of the slope of the laying surface. . In addition, the provision of a drainage ditches in the planting space narrows the planting space.

The present invention solves the above-mentioned disadvantages, and can reliably guide water such as rainwater to a water storage unit or a water holding unit, secure more moisture such as rainwater, and effectively use it for planting. Another object of the present invention is to provide inexpensive greening equipment with excellent workability. Another object of the present invention is to provide a greening facility that can guide water such as rainwater to a water storage unit or a water holding unit without reducing the planting area or securing the maximum planting area. I do.

The greening equipment of the present invention is a greening equipment configured by arranging a plurality of greening structures having a substantially box-shaped planting part above a water storage or water holding part capable of storing or holding water on a laying surface. A water flow path that allows water to be introduced into the water storage portion or the water retention portion between the adjacent planting portions; for example, rainwater from above a substantially box-shaped planting portion; Water from the flowing path between the side walls of the planting section to the water storage section or the water holding section. The planting section and / or the water storage section and / or the water holding section may have, for example, a substantially box shape having a side wall and a bottom surface, and preferably have an upper surface opening.

Furthermore, the greening equipment of the present invention is characterized in that the water flow path can introduce at least water that cannot be completely penetrated into the growing material of the planting part into the water storage part or the water holding part. Furthermore, the planting facility of the present invention is characterized in that an opening or a part of an opening of a substantially box-shaped water storage unit or a water retention unit is provided below a water flow path provided between the side walls of the planting unit. . For example, an opening is provided at least in the vicinity of the upper end of the side wall of the substantially box-shaped water storage section or water holding section, and the opening or a part of the opening is disposed outside the bottom of the substantially box-shaped planting section in plan view. I do.

Further, the greening equipment of the present invention may further comprise: forming a ridge and a groove in the side wall of the planting part in a substantially vertical direction, so that the ridge of one planting part of the adjacent planting part is formed by the other planting part. The water flow path is provided in a groove, and the flow path is provided in a gap between the ridge and the groove.

Furthermore, the greening equipment of the present invention is characterized in that the corresponding planting part and the water storage part or the water holding part are disposed so as to be shifted from each other in a plan view. For example, it is possible to use a planting part and a water storage part or a water retention part of the same shape and dispose them at different positions in plan view to provide a water flow path.

The greening facility of the present invention has a greening structure in which a planting section is provided on a water storage section or a water holding section, and a water flow path through which water can be introduced into the water storage section or the water holding section between adjacent planting sections. Therefore, it is possible to reliably guide the water such as rainwater to the water storage section or the water holding section, to secure more water such as rainwater, and to effectively utilize the water for planting. In particular, by adopting a configuration in which water that has not been completely penetrated into the growing material of the planting section flows through the water flow path and is guided to the water storage section or the water holding section, the water such as rainwater can be more reliably and in large quantities. It can be guided to the water retention department and used effectively for planting. Furthermore, by providing a water flow path between the planting parts, such as between the planting part side walls, it is possible to effectively use rainwater etc. without reducing or maximizing the planting area in the planting part. It can secure more planting area. Also, since a water flow path is provided between the planting parts, for example, a water flow path is provided between the fixed and fixed side walls, such a problem that an external force is applied to the growing material and the like and the water flow path is blocked. There is no need to secure a stable water flow path for a long time. In addition, the water storage or water holding section is formed in a substantially box shape with a top surface opening and side walls and a bottom surface, and a planting section is placed on the water storage section etc. to form a greening structure, so that water can be stored or held. More rainwater can be stored or retained for plant cultivation.

Furthermore, by disposing an opening or a part of the opening of the substantially box-shaped water storage unit or the water holding unit below the water flow path provided between the side walls of the planting parts, the water flows between the planting parts. It can be guided or dropped along the route and can be guided into the water storage unit or water storage unit through the opening of the water storage unit or water storage unit, and has a simple and inexpensive structure, which ensures stable and stable rainwater storage or water storage unit Can lead to

Furthermore, by disposing the ridge of one planting part of the adjacent planting part in the groove of the other planting part, and providing a flowing water path in a gap between the ridge and the groove, The flowing water path can more reliably and stably lead the water to the water storage section or the water holding section over a long period of time. In addition, since the greening structure can be constructed by laying the greening structure by arranging the ridges in the concave grooves, the positioning of the greening equipment becomes easy and the workability is improved.

Furthermore, by placing the corresponding planting part and the water storage part or the water holding part at positions deviated in plan view and placing the planting part in the water storage part or the water holding part and providing a flowing water path, it is simpler and cheaper. With this structure, it is possible to construct a water flow path that can reliably and stably guide rainwater to the water storage or water storage.

The greening equipment of the present invention has an effect that water such as rainwater is surely guided to a water storage or a water retention part, and more water such as rainwater can be secured and effectively used for planting. In other words, the amount of available water that can be effectively used for planting by being stored in a water storage section or the like can be dramatically increased, and ineffective water that is wastefully discharged without being guided to the water storage section can be reduced or eliminated as much as possible. In addition, it can be provided at low cost, and achieves excellent workability. In addition, water such as rainwater can be guided to the water storage or water retention unit for effective use without reducing the planting area or ensuring the maximum planting area.
