  Although the vegetation floating island of the structure disclosed in Patent Document 1 or Patent Document 2 is relatively inexpensive, it has a large number of parts and is still expensive to install an effective scale.

  On the other hand, since the vegetation floating island having the structure disclosed in Patent Document 3 has an independent float only at the end of the plant support material, the plant support material is partially submerged in water when the weight of plants or wild birds is added. Due to the fact that it is easy to use, there are problems such as limited types of plants and unsuitable as a resting place for wild birds. Further, since the float is exposed on the surface of the water independently, the appearance is extremely artificial and is not preferable from the viewpoint of landscape and the like.

  Therefore, the present invention has been made to solve such a problem, and parts such as a net can be omitted, the production cost can be suppressed, and the vegetation base material and the buoyant body can be integrated at any location. The purpose of the present invention is to provide a vegetation floating island that can be made uniform, can support the weight of plants and wild birds evenly, and can be made difficult to see as an artificial structure in appearance. .

  In order to achieve the above-mentioned purpose, the vegetation floating island according to the present invention is for planting plants and the like on a vegetation floating island in which plants are planted and floated in water areas such as lakes, rivers, and dams. A buoyant body for floating the vegetation base material including the plant to be planted is arranged on the vegetation base material of the vegetation, and a film is formed by attaching a synthetic resin to the buoyancy body over the vegetation base material, And the buoyancy body are integrated.

  In addition, the buoyancy body is uniformly arranged on the vegetation base material, and a film is formed by attaching a synthetic resin to the buoyancy body over the vegetation base material, thereby integrating the vegetation base material and the buoyancy body. It is what.

  Also, the buoyancy body is integrated with the buoyancy body by arranging the buoyancy body on the back side of the vegetation base material or by attaching a synthetic resin to the entire exposed part of the buoyancy body over the vegetation base material. It is characterized by having been made.

  Further, the synthetic resin is attached to an arbitrary portion of the vegetation base material.

  According to the present invention, by forming a film by attaching a synthetic resin over the vegetation base material to the buoyancy body, by integrating the vegetation base material and the buoyancy body, by omitting parts such as a net, It becomes a simple structure and the cost can be reduced. In addition, the vegetation base material and the buoyant body can be integrated at any location, and the weight of plants and wild birds can be evenly supported, making it difficult to see artificial structures from the outside. It becomes.

  Specifically, by arranging buoyant bodies evenly on the vegetation base material, forming a coating by attaching synthetic resin to the buoyancy body over the vegetation base material, and integrating the vegetation base material and the buoyancy body Can support the weight of plants and wild birds evenly.

  In addition, a buoyant body is placed on the back side of the vegetation base material, or a synthetic resin is applied to the entire exposed part of the buoyancy body over the vegetation base material to form a film, thereby integrating the vegetation base material and the buoyancy body. This makes it difficult to see an artificial structure from the outside.

  Further, by attaching the synthetic resin to an arbitrary portion of the vegetation base material, the partial or overall rigidity and strength can be easily increased.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view showing a basic configuration of an embodiment of a vegetation floating island according to the present invention, and FIG.

  The vegetation floating island F of this embodiment is formed on the back surface side of the substantially square vegetation base material 1 by forming four groove-like portions extending from one side to the opposite side thereof in the vicinity of both sides and between them, each of which is made of foamed polystyrene or the like. A square buoyant body 2 is disposed, and a synthetic resin film 3 is formed by attaching synthetic resin over the vegetation base material 1 over the entire exposed part of the back side and the side exposed part of each buoyant body 2 to form a vegetation base. The material 1 and the buoyancy body 2 are integrated.

  In the vegetation base material 1, a plurality of vegetation holes 4 for planting aqueous plants and the like to be described later are formed between the buoyancy bodies 2, and a mooring rope and a later described are adjacent to the periphery. A plurality of holes 5 for connection with vegetation floating islands or the like are formed through the front and back. In the present embodiment, the synthetic resin film 3 is formed by attaching synthetic resin to the front and back opening portions of the connection hole 5 to increase the strength of the connection hole 5.

  As the vegetation base material 1, a net-like body formed by irregularly entwining a continuous yarn having a thickness of about 1 to 2 mm made of an olefin-based synthetic resin such as polyethylene or polypropylene is lightweight. It is suitable because it has moderate rigidity and voids.

  On the other hand, as the buoyancy body 2, polystyrene foam and polyethylene foam are suitable because they are lightweight and inexpensive. When durability is required, a hollow polyethylene product is suitable because it has an appropriate strength and is relatively inexpensive.

  As the synthetic resin to be attached, materials such as polyurethane and polyurea are suitable because they have appropriate strength and moldability. For example, these resin materials are blown onto the vegetation base material 1 and the buoyant body 2. By attaching, the synthetic resin film 3 can be formed easily.

  As shown in FIG. 3, the vegetation floating island F configured as described above is in a state where plants 6 such as aquatic plants are planted, installed in water areas such as lakes, rivers, dams, etc., and floated on the water surface WL. Thus, the root 7 of the plant 6 that has been planted extends into the water, and nutrients such as organic matter contained in the water are absorbed by the plant 6 from the root 7, thereby effectively exerting the action of water purification.

  The vegetation floating island F in a state of floating on the water surface WL has a mooring line 8 connected to a connecting hole 4 formed on the vegetation base material 1 and reinforced with a synthetic resin coating 3 as shown in FIGS. The anchor (錨) 9 connected to the other end of the mooring line 8 is moored and fixed by being immersed in the bottom 10 of the water. Environmental conservation and recovery can be achieved.

  In addition, although the case where the vegetation floating island F was one was shown in FIG. 3, it is possible to connect a plurality of vegetation floating islands F by a connecting line or the like using the connection hole 4 and to install them floating.

  As described above, the vegetation floating island F of the present embodiment can omit a net or the like by integrating the vegetation base material 1 and the buoyant body 2 with the synthetic resin coating 3, and can suppress the production cost.

  Moreover, since the vegetation base material 1 and the buoyancy body 2 can be easily integrated at an arbitrary location, the buoyancy bodies 2 are evenly arranged on the vegetation base material 1 as in the above embodiment, and the vegetation base 2 is vegetated. By attaching a synthetic resin over the base material 1 to form the synthetic resin film 3 and integrating the vegetation base material 1 and the buoyant body 2, the weight of plants and wild birds can be supported uniformly.

  Moreover, the vegetation floating island F which has arbitrary rigidity partially or entirely by making a synthetic resin adhere to the connection hole 5 of the said embodiment, and other arbitrary places, and also adjusting the adhesion amount of a synthetic resin. Can be provided.

  Furthermore, since the entire exposed portion of the buoyancy body 2 is covered with the synthetic resin coating 3 and integrated with the vegetation base material 1, the buoyancy body 2 is not exposed on the water surface, so that it is difficult to see an artificial structure in appearance. Become.

  Moreover, durability of the vegetation floating island F is also improved by minimizing the number of parts.

  FIG. 4 is a plan view showing a basic configuration of another embodiment of the vegetation floating island according to the present invention, and FIG. 5 is a cross-sectional view taken along the line BB in FIG. ing.

  In the present embodiment, the buoyancy body 2 is formed in a columnar shape, and a large number of columnar buoyancy bodies 2 are evenly arranged in a dotted manner from the back surface side of the vegetation base material 1 to expose the back surface side of each buoyancy body 2. A synthetic resin film 3 is formed by attaching a synthetic resin over the entire surface of the vegetation base material 1, and the vegetation base material 1 and the buoyancy body 2 are integrated.

  Even if it comprises in this way, since the effect similar to the said embodiment is obtained, since the buoyancy body 2 is no longer exposed on the water surface, it becomes much more difficult to see an artificial structure in appearance.

  FIG. 6 is a plan view showing a basic configuration of still another embodiment of the vegetation floating island according to the present invention, and FIG. 7 is a CC cross-sectional view thereof. Is used.

  In the present embodiment, the buoyancy body 2 is continuously arranged evenly on the periphery (four sides) of the substantially square vegetation base material 1, and the synthetic resin is attached to the entire upper and lower side exposed portions of the buoyancy body 2 over the vegetation base material 1. In this way, the synthetic resin coating 3 is formed, and the vegetation base material 1 and the buoyancy body 2 are integrated.

  Even if comprised in this way, while being able to obtain the same effect as the said embodiment, the submergence of the peripheral part of the vegetation base material 1 can be prevented reliably. The configuration of this embodiment is suitable to be applied to a relatively small vegetation floating island F because there is no buoyancy body in the center, but a plurality of small vegetation floating islands F are connected by using the connection holes 5 to be installed in a floating manner. By doing so, it is possible to make a large area vegetation floating island.

  In each of the above embodiments, the vegetation base material 1 is substantially square. However, the present invention is not limited to this, and can be implemented in a polygon other than a circle or a square, and the buoyancy body is arranged in accordance with the shape of the vegetation base material. do it.
