Description of the Related Art Since dirt is conspicuous in waterside concrete where the water level fluctuates significantly, an urgent solution is desired from the viewpoint of landscape maintenance. However, since the waterside concrete wall does not have soil for growing plants, it cannot be applied like the greening method of the concrete wall on land, and there have been no successful cases so far.

付けることを特徴とする。The method for greening a waterside concrete wall according to the present invention is such that a greening frame having a two-dimensional expansion is slidably mounted on the concrete wall and the lower edge of the greening frame is covered with water. It is characterized in that it is connected to a float that is floated in a wrinkle, a green plant grows in the green frame, and the root of the plant is attached to the float.

栽培ができる。According to the method of the present invention, the float moves up and down according to the fluctuation of the water level, and the greening frame also moves up and down along the concrete wall according to the up and down of the float. Therefore, even if the water level changes, water is supplied to the roots of the plants planted in the float. Therefore, it is possible to grow plants on the waterside concrete wall.

ので，これを水辺コンクリート壁で植栽することによっ
て，水質浄化作用も供する。Also, depending on how the roots are attached to the float, it is possible to grow not only aquatic plants but also terrestrial plants.
That is, in the case of terrestrial plants, it is sufficient to attach them to the float so that the upper part of the root, which receives supplemental oxygen from the air, comes into contact with the air, and only the lower part of the root comes into contact with water.
At that time, it is convenient to wrap the root part with a porous, water-absorbent sheet or the like, as it will come into contact with air and water. Since terrestrial plants have a high ability to absorb nutrients such as nitrogen and phosphorus in water, planting them on a waterside concrete wall also provides water purification.

This mooring means uses elastic ropes (rubber ropes) for small scales, and for relatively large scales, installs vertical rails or rail grooves on the concrete wall, and floats 2
The float 2 is vertically movably moored by attaching a pulley that slides while being locked to the rail to the tip of the out-trigger 5 or attaching a slidable key to the rail groove. In any case, any mooring method can be used as long as the float 2 can freely move up and down along the concrete wall 1 according to the fluctuation of the water surface. For example, the rack-shaped teeth and the gears that engage with them cannot be separated It is also possible to adopt a method of connecting to.

That is, in a vinyl house or the like, the plant is made to grow in a greening frame using a culture soil suitable for the plant. Examples of plants are not particularly limited, but hederas, Plutella xylostella, and the like are preferable because their growth can be secured in a short period of time.

The root portion is dug up from the culture soil, wrapped with a porous water absorbing sheet (nonwoven fabric) 16, and transported to the site of the waterside concrete wall. Then, depending on the type of terrestrial plant, it is inserted into the groove 6 of the float 2 while being wrapped with this sheet 16. As a result, oxygen in the air is supplied to the root portion inside the sheet 16 while retaining an appropriate amount of water, so that the planting can be performed in the same manner as on land. The sheet can be inserted into the groove 6 without being wrapped with the sheet, but in this case also, a terrestrial plant can be planted by inserting the root so as to be in contact with the air. In the case of aquatic plants, the roots may be immersed in water and supported by a float.

い。INDUSTRIAL APPLICABILITY As described above, according to the present invention, the waterside concrete wall can be greened not only by the aqueous plants but also by the terrestrial plants. For this reason, it is possible to change a concrete wall such as a dam, a riverside, or a pond, where dirt is conspicuous, into a beautiful green surface, so that the landscape is improved and overheating of the concrete wall due to solar radiation can be reduced.
Also, the water supply for the vegetation is replenished from the water surface,
There is no need for artificial control, and maintenance can be carried out by spraying appropriate nutrients on the leaves as needed.

揮できる。According to the method of the present invention, the plants can be grown on the greening frame in the cultivation house and the grown plants can be connected to the float so that they can be replaced. Accordingly, various plants can be arbitrarily planted on the waterside concrete wall according to the flowering and damage of the plants. For this reason, in tourist spots where landscape is particularly important, the effect is great due to the ease of landscape modification.
