Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of groundwater aeration ground which is effective for growing plants.

[0002]

2. Description of the Related Art Conventionally, in a plant growing area, only a plant is planted on a fertilized soil surface, and a concept for creating a groundwater aeration ground has not been proposed yet.

[0003]

Therefore, when growing plants, it is needless to say that appropriate fertilization has been carried out until now, but no special concrete means have been taken.
It was merely a matter of raising the plant by the quality of the plant itself.

The present invention has been made against the background of such conventional circumstances, and in addition to growing a plant having a strong root,
The objective is to provide a structure of groundwater aeration ground that prevents the root from freezing during winter.

[0005]

The present invention provides a box surrounded by a surface layer on which a plant is planted, a side water-impervious material that digs into at least a part of the surface layer, and a bottom water-impervious material laid on the entire bottom surface. A plant breeding characterized by comprising a flowing water layer formed by forming a mold area, drainage means for removing accumulated water in the flowing water layer, and water supply means for supplying water to the flowing water layer. It provides the structure of the groundwater subgrade.

In the present invention, the running water layer is a water-conducting layer portion provided by using a crimped bristle mat under the surface layer, and a gravel-filled water storage layer provided under the water guiding layer portion through a water-permeable cloth. It provides the structure of the groundwater aeration ground of the plant growing area formed by the layers.

In the present invention, the drainage means is a siphon connected to a drain pipe penetrating the lower portion of the side water blocking member, a branch drain pipe provided with a drain valve and branched from the drain pipe, (EN) A structure of a groundwater downstream ground of a plant growing ground, which is provided with a net-like pipe located in a water storage layer portion and connected to the drainage pipe.

Further, in the present invention, the water supply means is provided with a buried water supply pipe penetrating the surface layer and connected to the water guiding layer portion, a water supply valve and a water fertilizer mixer, and detachably connected by the connection part of the buried water supply pipe. The present invention provides a structure of a groundwater aeration ground of a plant growing area, which is provided with a water supply pipe.

[0009]

In the groundwater downstream ground constructed according to the present invention, rainwater permeates the surface layer, and the water supplied from the water supply pipe directly infiltrates into the water-conducting layer part, and further passes through the water-permeable fabric to store water. It enters the layer and collects. When the water level of the accumulated water in the reservoir layer gradually rises and reaches the water level at which the siphon of the drainage means operates, the accumulated water is expelled all at once outside the groundwater ground. At this time, since the pressure in the water storage layer is rapidly reduced, the atmosphere is inhaled through the surface layer and the water transfer layer to supply oxygen to the roots, so that the roots are firmly grown. Further, during the winter period, tap water is allowed to flow into the ground with the water supply valve and the drain valve left slightly open to prevent freezing of roots by avoiding freezing due to a temperature decrease. In addition, if a water fertilizer mixer is used, fertilization of aqueous fertilizer can also be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In addition, in the present embodiment, as a plant, the case of turfgrass used for a golf course green is taken as an example. In the groundwater aeration ground 01 of the present embodiment, as shown in FIG. 1, reference numeral 10 is a surface layer of sand or soil particles having a thickness of about 250 mm on which turf grass is planted, and reference numeral 20 is at least a part of the surface layer 10. With a running water layer formed by forming a box-shaped area surrounded by the side water-impervious material 02 formed with the impermeable water-impervious wall and the bottom water-impervious material 03 using the waterproof sheet laid on the entire bottom surface. is there. It should be noted that the sand is preferably sand from Takasu, for example, and the grain size distribution has a rough and concentrated feeling,
It can be walked on and squeezed, and contains fertilizer. The running water layer 20 is formed on the lower surface of the surface layer 10 by using a mat made of crimped bristle yarn having a thickness of about 50 mm [Madeda Kosen Co., Ltd., Endren Mat (EM-50C)]. 30 and a water storage layer formed by filling a gravel gravel having a diameter of about 10 mm to a thickness of about 150 mm through a nonwoven fabric [CF-150G manufactured by Maeda Kosen Co., Ltd.] as a water-permeable fabric 31 laid on the entire lower surface thereof. And part 40. The drainage means 50 is a siphon 53 connected to a drain pipe 52 penetrating the lower portion of the side water-impervious material 02, and a drain pipe 52 is branched from the middle of the drain pipe 52.
A branch drain pipe 54 (vinyl chloride resin pipe) having a drain valve 55, and a plurality of net-shaped pipes 51 arranged in the water storage layer portion 40 and connected to the drain pipe 52 [Maeda Industrial Fiber Co., Ltd.]. Manufactured by Monodrain (MD Y-3)]. The water supply means 60 includes an embedded water supply pipe 65 penetrating the surface layer 10 and connected to the water guide layer portion 30, a water supply valve 62 and a water fertilizer mixer 63, and the connection portion 6 of the embedded water supply pipe 65.
6, and a water supply pipe 61 that is detachably connected by 6 is provided. In addition, reference numeral 67 is a water supply guide cover made of a non-woven fabric, which is formed in a reverse funnel shape and is fitted onto the tip of the water supply pipe 61.

Due to the above-mentioned structure, rainwater permeates from the turf surface 11 to the surface layer 10 when it rains, and the water-conducting layer portion 30.
From the crimped bristle yarn mat, it passes through the water-permeable fabric 31 and flows into the water storage layer portion 40 and stays there. Thus, accumulated water 05
When the water level rises and reaches the bent portion of the siphon 53, the siphon action causes the accumulated water 05 to be discharged all at once through the net-like pipe 51, the drain pipe 52, and the siphon 53 to the outside of the groundwater ground 01, and the reservoir layer Retained water 05 remaining in section 40
Returns to the original minimum water level. Therefore, the atmospheric pressure in the flowing water layer 20 suddenly drops, and the atmosphere is rapidly sucked into the surface layer 10, so that oxygen in the air is supplied to the roots of the turfgrass 04. That is, the roots of the turfgrass 04 are firmly grown by repeating this siphon action. When there is no rainfall, water supply means 6 is used in addition to watering in the morning and evening.
By supplying water to the flowing water layer 20 using 0, the same action and effect as described above can be obtained. Further, in the winter period, if the tap water of about 12 ° C. is supplied into the groundwater downstream ground 01 while the water supply valve 62 and the drainage valve 55 are slightly opened to maintain the flowing water state, the ground 01 Since the internal temperature drop is prevented and freezing is prevented, the roots of the turfgrass 04 are never frozen. Further, by removing the cap 64 from the water fertilizer mixer 63 of the water supply means 60 and supplying the aqueous fertilizer, the fertilizing effect can be improved. When using green, the water supply pipe 61 is removed from the connecting portion 66 and removed, and the connecting portion 66 is covered with a cover (not shown).

Since the mat made of crimped bristle yarn is used for the water-conducting layer portion 30, the contact area with the sand is large and the connection with the buried water supply pipe 65 in the case of an underground dam is easy. This increases the water permeability, so even if the inclination is slight, the water flows straight in the draining direction and there is concern that the fertilizer may flow out, but the crimped bristle mat has resistance to the water flow and To prevent the flow of fertilizer.

In the embodiment described above, the water guiding layer portion 30 using the mat made of crimped bristle yarn is laid on the entire surface of the groundwater downstream ground 01, but as another embodiment, as shown in FIG. In the surface layer 10B, for example, a width of 1 m to 1.5 m and a length of 7
m, a water-conducting layer block 30B made of crimped bristle yarn formed to have a thickness of 50 mm, and a net-shaped pipe group 51B provided in the water storage layer portion 40 as one unit, and a plurality of units are arranged, Drain means 50 and water supply means 6
0 may be assembled to configure the groundwater downstream ground 01B.
At this time, a branch water supply pipe (not shown) is guided from the buried water supply pipe 65 to the water guiding layer block 30B of each unit,
On the other hand, each net-shaped pipe group 51B collects terminals and connects them to the drain pipe 52. In addition, 02B is a side water-impervious material, 03
B is a bottom water-impervious material. These water-blocking materials in this case are
In addition to metal and plastic sheets, materials with low water permeability such as clay are sufficient.

Although the embodiment of the present invention has been described above, the present invention is not necessarily limited to this embodiment, and a design change and the like without departing from the scope of the invention are included in the present invention.

[0015]

As described above, according to the present invention, the water-conducting layer portion of the mat made of crimped bristle yarn and the water-storing layer portion of the gravel filled with the water-permeable cloth interposed under the surface layer on which the plant is planted. Since a running water layer consisting of and is provided, the drainage means using a siphon and a water supply means for directly feeding water to the running water layer are assembled to this, and a groundwater downstream of the plant growing ground is constructed.
Oxygen is inhaled into the surface layer by the siphoning drainage, so that strong roots can be grown and the groundwater in the winter can prevent the roots from freezing. Further, since the water-conducting layer portion is formed by the mat made of crimped bristle yarn, the applied water-based fertilizer is also retained and the runoff is avoided.
