Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is to provide a place for spawning, nesting, rest, etc. for animals such as birds and fish, as well as greening and water purification on the surface of water such as lakes, ponds, rivers, seas and moats. It concerns the artificial floating islands used.

2. Description of the Related Art Conventionally, a device of this type is disclosed in, for example, Japanese Utility Model Publication No. 4-33739. However, this device uses two buoyancy frames formed by expanding a net-like body to grow plants. The present invention relates to a plant-raising reef characterized by having an integrated floor.

[0003]

In the above-mentioned plant-raising reef, the on-site assembly is extremely easy due to the method in which the buoyancy frame in which the net-like material is spread is formed into a sandwich structure.
It is easy to do, and it is possible to make the buoyancy frame stably hold the plant growing floor and evenly distribute the buoyancy.
It is said that a plant-raising reef that can withstand long-term use can be provided. However, according to the configuration of this plant-raising reef, when a plurality of plant-raising reefs are used in combination, a plurality of such reefs can be used. There is a problem that it takes a lot of effort to connect the plant reefs to each other with ropes or strings, and there is a limit to the variation of combinations, so it is difficult to use them in an appropriate combination according to the place of use and purpose of use. is there. The present invention solves the above-mentioned conventional problems and makes it possible to make a variety of combinations of a plurality of artificial floating islands, so that the places of use such as lakes, rivers, the sea, and moats, the natural environmental conditions and the purpose of use, etc. The purpose is to provide an artificial floating island that can be used in a combination that accurately corresponds to.

[0004]

In order to achieve the above object, the artificial floating island according to the first invention accommodates a plant growth base 5 in a frame of a frame body 1 formed in a triangular shape, and this plant growth base is Triangular nets 7 and 7 stacked on the upper and lower sides of 5, respectively
The peripheral edge of ‘′ is fixed to the upper surface and the lower surface of the frame body 1, and the net 7 on the upper surface is provided with a planting hole 8 for a plant.
As the frame body 1 formed in the triangular shape, for example, a frame body formed in a triangular shape by connecting the respective ends of the three cylindrical side frame sides 2 to the side walls of the corner prism 3 can be cited. In addition, the plant growth base 5 may be a plant growth base made of a plant fiber having a cork particle layer 6 in between.

The artificial floating island according to the second aspect of the present invention is formed by fixing the peripheral edges of a triangular cover plate 9 and a bottom plate 9'on the upper surface and the lower surface of the frame body 1 formed in a triangular shape. The frame body 1 formed in the triangular shape is formed in a triangular shape by connecting the respective ends of the three cylindrical side frame sides 2 to the side walls of the corner prism 3 as in the case of the first invention. The frame can be raised.

[0006]

With respect to the artificial floating island according to the first aspect of the present invention, before or after launching (floating on the water surface) or after launching, plants are planted on the plant growth base 5 through the planting holes 8 formed in the net 7 on the upper surface. Examples of plants to be planted include reeds, cattails, macaws, ginger, oysters, vines, sedges, rushes, futoys, cornweeds, willows, alder trees,
Etc. The planted plant grows on the plant growth base 5, the roots and rhizomes also grow through the plant growth base 5, and oxygen is supplied by the assimilation of organisms. Absorption of organic matter. Filter effect by rooting under the water.
Rooting and nurturing action of microorganisms (bacteria) effectively performed by roots of a wide surface area with constantly growing underwater divergence. Neutralization of alkaline or acidic water in the area where dangerous sewage flows (pH adjustment effect)
To prevent the inhibition of aeration of water by phytoplankton. Absorbs heavy metals and phenolic compounds.
Settling and removal of colloidal substances. The water purification function will be exerted by the comprehensive action of the above.

When a cork particle layer 6 is sandwiched in the middle of a frame body 1 formed in a triangular shape to accommodate a plant growth base 5 made of plant fiber, the plant made of the plant fiber described above is used. The growth base 5 is suitable for growing roots of plants, and since cork particles have a property of being extremely light in weight and absorbing little water, the buoyancy of the entire artificial floating island can be increased and at the same time, in the middle layer. It may provide the conditions that are favorable for creating the interstices and allowing the plants to form the roots well and well.

In the artificial floating island according to the second aspect of the present invention, the artificial floating island is floated on the water surface and then directly or on the lid plate 9 on the upper surface.
Used in a state where gravel, crushed stone, wood chips, etc. are placed on a mounting table (not shown) supported above, and if necessary, appropriately combined with the artificial floating island according to the first invention by a connecting means described later. It can provide a place for birds to rest and breed.

In the artificial floating island according to the first invention for planting the above plant or the artificial floating island according to the second invention for mounting gravel or the like,
When the frame body 1 formed in a triangular shape is a frame body formed in a triangular shape by connecting the respective ends of the three cylindrical side frame sides 2 to the side walls of the corner prism 3, these artificial floating islands are used. When connecting a plurality of the above, the corner pillars 3 are provided at the corners of any of the artificial floating islands, and therefore it is possible to connect them very easily. That is, for example, as shown in FIG. 9 and FIG. 10, at the upper end of the negative prism (the right corner corner in the drawing) of the corner pillars 3 of the two artificial floating islands adjacent to each other on the shore or on the water surface. Fit the polychloroprene cushioning ring 11 and then the rubber tension ring 12
Fiber and synthetic rubber connecting ring 13
By hanging on the upper part of both corner prisms 3, a plurality of artificial floating islands can be easily connected to each other.

Since the artificial floating island according to the present invention has a triangular shape as a whole, it has a characteristic that it is not easily affected by waves, and a plurality of artificial floating islands are used in combination by adopting the above connecting means and the like. The variations in this case are extremely rich as illustrated in FIG.

The artificial floating island according to the present invention is shown in FIG.
As shown in FIG. 2, it is usually used by floating it in a stable state at a certain point on the water surface by a method of mooring it to an anchor 15 with a mooring rope 14.

As described above, the artificial floating island according to the first invention for planting plants has a water purification function. In addition to this, the artificial floating island according to the first invention and the artificial floating island according to the second invention are both birds and It has an ecological function to provide a place for resting and breeding for animals such as fish, a landscape function to create a natural scene on the waterside, and a seawall function to prevent erosion of the shore due to water currents and waves.
