Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention conveys artificial plants such as artificial turf together with a container and continuously lays them to construct a stadium such as a soccer field, a green space in a park, a green space on a rooftop floor, etc. TECHNICAL FIELD The present invention relates to a container for artificial planting that is suitable for carrying out, and a continuous laying method thereof.

[0002]

2. Description of the Related Art Conventionally, as a method of creating a stadium, a green space in a park, a green space on a rooftop floor, etc., a natural planting method such as natural grass is artificially planted, or artificial grass such as artificial grass is used instead of natural planting. There is a way to place. Although natural planting has advantages over artificial planting such as having the texture of natural products, not only does the vegetation state vary depending on the season or the cultivated area or grower, but the vegetation state at the time of laying is uniform. However, after installation, it is necessary to sprinkle water appropriately to prevent it from dying, but it is also necessary to remove excess water, and maintenance is troublesome because of the risk of disease, and There is a problem that it is easy to be damaged in the case where the green ground is open or in the case of a stadium, and when it is damaged, it takes a long time to recover and it is necessary to establish a restricted area.

Therefore, in recent years, artificial planting of artificial turf or the like has been increasingly adopted as a means for such greening. Such artificial plantings were generally placed directly above the concrete surface.

[0004]

However, there is no problem in natural planting because the planting itself and the soil have a water retaining function, but it is necessary to construct a concrete surface when laying artificial planting. Therefore, in addition to the fact that artificial planting itself does not have a water-retaining function, the heat island phenomenon (a phenomenon in which islands that do not drop in temperature even at night) is presently a problem in urban areas such as central Tokyo. It will help.

Further, as a method for laying artificial planting, there are a method of laying rectangular sheets vertically and horizontally without a gap, and a method of unrolling rolled sheets, but either method is also available. There is a problem that it is necessary to rely on human labor and skill is required for continuous laying so that a seam does not occur on the planting surface.

The present invention has been made in order to solve the above problems, and has a water retaining function to suppress the heat island phenomenon so that no seam is formed on the planting surface without requiring skill. An object is to provide a container for artificial planting and a continuous laying method thereof.

[0007]

In order to achieve the above object, the invention according to claim 1 has a water tank in which water is stored in the lower portion, and a water retaining material such as a nonwoven fabric is held in the upper portion thereof. And a container main body in which artificial planting is arranged on the uppermost part of the water retaining material, and the entire lower surface of the holding area of the water retaining material or a large part thereof and substantially the center of the water storage tank, which is provided in an approximately middle portion of the container main body. And a shape-retaining portion that holds the capillary action member in the shape of an inverted cone.

In the invention according to claim 2, the water retaining material layer is
It is characterized in that it is set higher than the upper end of the container body.

The invention according to claim 3 is characterized in that the contour line of the water retaining material is substantially aligned with the contour line of the container body in the vertical direction.

The invention according to claim 4 relates to claim 1, 2, 3
A method for continuously laying a container for artificial planting according to any one of 1), having a rigidity that does not allow it to hang down by its own weight, and a length that allows it to be bridged between the water tanks of two adjacent containers. One end of the capillary action piece having is immersed in a water tank of one of the containers so that the other end is projected from the container, another container is brought close to the container, and the other end of the capillary action piece is connected to the other container. After holding the container toward the water tank, the two containers are brought into contact with each other.

[0011]

In the above structure, by laying the containers continuously, it is possible to quickly and easily create a stadium, a green space in a park, or the like. Water is retained in the water retaining material layer by rainfall or water sprinkling, and excess water is stored in the water storage tank. When the water content of the water retaining material decreases, the water in the water storage tank is sucked up by the water retaining material due to the capillary action of the capillary action member. At this time, the capillary action member, which is shaped like an inverted cone, connects most of the water-retaining material layer in plan view and almost the center of the water-reservoir, so that the water in the water-reservoir covers the entire surface of the water-retaining material. Go around. Therefore, an appropriate amount of water is always retained in the water retaining material (claim 1).

If the upper end of the water retention material is set higher than the upper end of the container body, the upper end of the container body will not be exposed from the surface of the artificial planting even if the water retention material is depressed to some extent by the pedaling force of a person (claim) Item 2).

If the contour of the water retaining material is substantially in line with the contour of the container body in the vertical direction, adjacent water retaining materials will come into contact with each other when the containers are continuously laid, and no seam will occur. 3).

One end of the capillary action piece is immersed in the water tank of any container so that the other end projects from the container, another container is brought close to the container, and the other end of the capillary action piece is connected. After holding it toward the water tank of another container, if the two containers are brought into contact with each other, the capillary action piece has such a length that it can be bridged between the water tanks of two adjacent containers, so that the two Since water can flow between the containers and the capillary action piece has a rigidity that does not hang down by its own weight, it does not hang down between adjacent containers and can therefore be prevented from being sandwiched between the containers. A seam is prevented from being formed on the surface of the planting (claim 4).

[0015]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a preferred embodiment of the present invention,
Artificial planting container (hereinafter simply referred to as container) 1
A container main body 1A having a water storage tank 2 for storing water is provided, and inside the container main body 1A, a substantially central portion of an inner bottom portion (water storage tank 2) and an intermediate portion in the height direction (a holding area of a water retaining material) are provided. Funnel-shaped inclined surface (shape retention part) so as to connect with the bottom surface)
3 is formed so as to be inclined over the entire surface. A large number of lightweight drainage materials 4 (capillary action members) such as hydroballs (calcined products such as coke and coal) and diatomaceous earth baked products are put on the inclined surface portion 3, and the lightweight drainage material 4 corresponds to the shape of the inclined surface portion 3. The shape is retained in the inverted cone shape. A non-woven fabric layer 5 in which a non-woven fabric (water retaining material) is laminated is carried on the container body 1A above the drainage material 4, and a perforated artificial turf sheet 6 is arranged above the non-woven fabric layer 5 as an example of artificial planting. ing.

Further, the outline of the nonwoven fabric layer 5 is substantially vertically aligned with the outline of the container body 1A, and the upper surface (planting surface) of the nonwoven fabric layer 5 is set higher than the upper end of the container 1A. There is. Therefore, the outer peripheral edge of the nonwoven fabric layer 5 is laminated on the edge of the container body 1A.

A large number of holes 7 are formed in the inclined surface portion 3 to allow water to flow therethrough. If the diameter of the funnel-shaped central portion is made large, a large amount of the drainage material 4 will be submerged in the water, and the amount of water sucked up will increase. Therefore, the shape and size of the inclined surface portion 3 are determined according to the quality of the water retaining material used and the planting to be cultivated.

Also, at the bottom of the side wall of the container body 1A,
A horizontally long window 8 is formed at a position lower than the connecting portion with the inclined surface portion 3, and water is passed between the adjacent containers 1 and 1 through this window 8 and ventilation is secured. To keep the water aerobic.

A lift guide 9 having a hollow rectangular cross section is integrally provided at the bottom of the container body 1A. The guide 9 has such a size and shape that a claw of a forklift used when transporting the container 1 can be inserted from four directions of front, rear, left, and right to improve the workability of transportation and improve the rigidity of the entire container 1. .

The container body 1A is provided with partition walls 10 which partition the container body 1A in a plan view, and the partition wall 10 improves the rigidity of the entire container 1 so that its thickness can be reduced and, in turn, the container. 1. It is possible to reduce the weight of the entire device. Further, for example, when a game is played on artificial turf, the treading force of the player can be received by the container body 1A via the partition wall 10 and the drainage material 4 can be prevented from becoming ubiquitous. Further, a slit 11 is formed in the partition wall 10 to allow horizontal water flow.

The operation of this embodiment will be described below.

[Container Transport] Each container 1 is individually transported to a destination such as a stadium. For transportation, the pawl of a forklift truck is inserted into the guide 9 so that it can be easily placed on a vehicle. When the vehicle arrives at the laying place, the claws of the forklift are again inserted into the guide 9 and the container 1 is laid down on the ground.

[Continuous Laying Method] Next, a well-known paper drain material is appropriately sized (two adjacent containers 1,
One of the containers 1 has one end of a piece (capillary action piece) 12 cut into a length such that it can be bridged between the water storage tanks 2 and 2 and a width dimension and a thickness dimension that can be inserted into the window 8. It is inserted from 8, and this is immersed in the water tank 2 so that the other end is projected from the container 1. Then, another container is brought close to the container 1, the other end of the paper drain piece 12 is inserted and held in the window 8 of the other container, and the two containers are pulled together by a forklift. At this time, since the paper drain piece 12 has such a rigidity that it does not hang down due to its own weight, it does not hang down between adjacent containers, and therefore can be prevented from being sandwiched between the containers.

Moreover, if the two containers are pulled together as they are, the outline of the non-woven fabric layer 5 and the outline of the container body 1A are substantially in the vertical position, so that the paper drain piece 12 is placed between the containers 1 and 1. In addition to not being pinched, the two containers will come into contact. At this time, when the two containers 1 and 1 come into contact with each other, the respective non-woven fabric layers 5 come into contact with each other so that no seam is generated on the planting surface.
Further, the other end of the paper drain piece 12 is immersed in the water tank of the other container, and water can be transferred between the two containers 1 and 1 via the paper drain piece 12.
Keep the liquid level in the water tanks of adjacent containers at the same level.

By carrying out the above-mentioned laying work in sequence, it is possible to easily construct a stadium with no planting surface.

It should be noted that it is preferable that adjacent containers are fixed to each other by any of the fastening means.

[Operation after continuous laying] When the laying place is outdoors, it is rained. When rain is insufficient even outdoors, or when the laying place is indoors, appropriate watering is applied. Water is supplied to the surface of the nonwoven fabric layer 5. The rainwater and the like are retained by the water retaining action of the nonwoven fabric layer 5, and the surplus water drops on the side of the drainage material 4 group. Drainage material 4
Promotes drainage of excess water supplied to the non-woven fabric layer 5, and keeps the non-woven fabric layer 5 in a certain water retention state. The water that has passed through the drainage material 4 is dropped into the water tank 2 through the hole 7 of the inclined surface portion 3. Water of the same level is stored in the other containers through the paper drain piece 12. The drainage material 4 is immersed in the water in the water storage tank 2.

When rainfall or watering is insufficient, the water stored in the water storage tank 2 is sucked up by the capillary action of the drainage material 4, and the required amount of the water in the nonwoven fabric layer 5 (varies depending on the water retention state of the nonwoven fabric layer 5 or the drainage material 4). Water) is supplied. In this way, even if there is insufficient or no rainfall,
Further, even if the sprinkling time is not sufficiently controlled, the heat island phenomenon in the place where the container 1 is laid can be prevented by constantly supplying the appropriate amount of water to the nonwoven fabric layer 5. The drainage material 4 is carried by the funnel-shaped inclined surface portion 3 and has an inverted pyramidal shape, and the upper surface of the group of drainage materials 4 is continuous with the entire lower surface of the nonwoven fabric layer 5, so that it is viewed in a plan view. Water can be evenly supplied over the entire surface of the nonwoven fabric layer 5. Further, the water distribution of each container 1 when viewed in plan can be made uniform, and even if excess water is supplied to a part of the non-woven fabric layer 5 of the container 1 at the time of watering, the water content of the non-woven fabric layer 5 is uneven. In addition to the fact that water is evenly distributed between the containers 1 and 1, there is no unevenness of water in the entire green space where the containers 1 are continuously laid.

[Movement of continuously laid containers] By the way, if artificial turf in a specific container is damaged after continuous laying of containers, or if the whole is completely replaced with another planting (including natural planting) In some cases, forklifts can be used to separate individual containers for rapid movement.

[Other] For the above containers 1,
For example, in the case of being laid for the ground where a soccer game is played, the plane size is 200 cm × 200 cm, the height size is 5 to 10 cm with the guide 9, and the container body 20 is 7-1.
5 cm, 7 from the top edge of the container body 20 to the planting surface
It may be about 15 cm. Also, the total weight is 300k
It is preferable that the weight is about 400 g and the maximum is 400 kg in terms of transportation work by a forklift, and in order to reduce the overall weight, it is preferable to use a lightweight water retaining material layer such as the nonwoven fabric as the nonwoven fabric layer 5.

According to the present invention, since the partition wall 10 is provided, it is possible to realize a large-sized container while the transportation work by the forklift is good.

In the above embodiment, the capillary action member is constructed by charging the drainage material 4 into the inclined surface portion 3 formed on the container body 1A, but the inclined surface portion 3 may be replaced by a mesh, or the inclined surface portion 3 may be used. Also, the drainage material 4 as a whole may be replaced with an inverted cone-shaped drainage material having self-shape retention.

The artificial planting is not limited to turf, but may be an artificial large tree, shrub, flower or the like. Further, by laying a plurality of containers 1 and 1 on which these various kinds of planting have been performed continuously, it is possible to create a garden that is rich in variety.

Further, in the above embodiment, the planting surface formed by continuously laying a plurality of containers is a flat surface, but it can be continuously inclined, and in this case, the revetment can be greened. It is possible. Further, it is also possible to continuously form a surface having a rugged shape such as a mountain shape or a valley shape. In these cases, since the height of the frame body is also changed according to the height of the planting surface, in order to increase the versatility of the container 1, an auxiliary frame that can be detachably connected to the container body 1A. You should set your body.

[0035]

As described above, according to the present invention, by continuously laying a container, it is possible to quickly and easily create a green space without requiring skill unlike conventional sheets, and a water retaining material. Since an appropriate amount of water is always retained over the entire surface without causing unevenness in the water, the moisture of the water retaining material is gradually evaporated during fine weather or cloudy weather, so that the heat island phenomenon can be suppressed (claim 1).

If the upper end of the water retention material is set higher than the upper end of the container body, the upper end of the container body is exposed from the surface of the artificial planting even if the water retention material is depressed to some extent by the pedaling force of a person. Therefore, it does not hinder walking or competition (Claim 2).

If the outline of the water retaining material is substantially aligned with the outline of the container body in the vertical direction, adjacent water retaining materials may come into contact with each other when the container is continuously laid, and a seam may be formed on the planting surface. It is prevented and does not hinder walking, competitions, etc., and has a good appearance (claim 3).

A seam is formed on the surface of the artificial planting, because the capillary action piece that allows water to flow between the two containers does not hang down between adjacent containers, and thus can be prevented from being sandwiched between the containers. Is prevented
As a result, it does not hinder competition and has a good appearance (Claim 4).
