DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating structure for planting to grow plants on artificial water reservoirs such as dam lakes, or on the water surface or seawalls in natural lakes and marshes, and on lake slopes caused by fluctuations in water levels. Things.

[0002]

2. Description of the Related Art In recent years, various problems have been raised regarding the water resources of dam lakes and the landscape of dam lakes themselves. In other words, in a dam lake, etc., plants that grew on the slope of the lake shore when they are full are covered with water and die. Not only is the landscape significantly impaired, but also the erosion of the slope surface during rainfall causes sedimentation on the lake bottom.

[0003] Further, during the drought period, the natural environment at the water's edge for the inhabitation of microorganisms changes due to the exposure of the scalp, and problems such as the occurrence of water bloom due to a decrease in water purification ability have arisen. .

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the applicant of the present invention has been researching and solving the problems to solve these problems. That is, the present application is also consistent with this, and aims to grow plants on artificial water reservoirs such as dam lakes, or on the lake surface and seawalls in natural lakes and marshes caused by fluctuations in water level, etc., as well as wild birds, seafood, aquatic insects, etc. It is an object of the present invention to provide a floating structure for planting that can secure a habitat of a plant and improve a natural environment in addition to an effect of improving water quality by growing plants.

Three-dimensional reticulated body surrounding the sheet for preventing rooting material from flowing out
A structure comprising a synthetic resin fiber coated sheet formed by surrounding and integrating the foamable floating member and a planting rooting material that fits into a planting cavity of the three-dimensional reticulated skeleton and vegetates plants. It is the gist.

[0006] Further, it is possible to adopt a structure in which an anchoring sheet for preventing passage of plant roots is interposed between the lower surface of the planting root material outflow preventing sheet and the foamable floating member.

A connecting structure in which synthetic resin fibers are knitted in a ladder shape or a band shape is sewn on the side and / or bottom surface of the floating structure for planting, and a mat is provided to connect the mats or to be detachable. The gist of the present invention is to make it possible to adjust the draft height at the time of floating, or to detachably attach a net for inhabiting microorganisms formed by knitting or weaving a net-shaped three-dimensional fishing reef and / or synthetic resin fiber.

[0008]

According to the floating structure for planting described above, a large number of plantings are used in which a root material for root planting is inserted into a three-dimensional reticulated skeleton formed by molding a synthetic resin fiber into a three-dimensional reticulated body. Because it has a structure with a cavity, it has sufficient rigidity against external deformation load, and it can be used when the floating structure for planting is installed on the water surface or when it is installed on the slope of the lake shore. There is no deformation due to gravity.

[0009] In addition, by the rooting material inserted into the plant cavity,
In addition to ensuring the rooting of the plant, the voids in the three-dimensional reticular body itself keep the elongation of the root of the plant in an appropriate state, and thus act to eliminate growth inhibition of the root of the plant.

[0010] In the structure provided with the anchoring sheet, the root of the plant is prevented from extending below the foamable floating member by the anchoring sheet. To prevent the roots from growing and being fixed to the slope.

The above floating structure for planting is designed to prevent movement and spillage by being tied by anchors and ropes at the bottom of the lake, but by appropriately setting the length of the ropes, the rising and falling of the water surface can be prevented. Can be followed. In addition, by changing the volume of the foamable floating member integrated with the bottom surface or changing the weight of the heavyweight, it is possible to change the draft height of the floating structure for planting and install it at any position in the water It is.

The floating structure for planting can be used by connecting a plurality of the floating structures in a plane direction by using a linking structure, and by continuously covering the slope from the lake shore to the water surface. Exposure of the ground on the slope can be eliminated. Then, by continuously installing the slope on the bare land that occurs in the low water level due to the fluctuation of the water level, the planting of the slope can be recovered. In the high water stage, the plant floating structure floats on the water surface, so that the plant is not submerged and withered as in the prior art, and the growth is maintained.

When the above-mentioned floating structure for planting is installed on the water surface, the absorption of nutrients in the water by the planting is achieved.
Water quality can be improved. Furthermore, an environment suitable for spawning of fish can be formed by attaching a net-shaped three-dimensional reef, and improvement of water quality by microorganisms can be expected by attaching a microorganism-inhabiting net.
