Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial floating greening ground for artificially promoting greening on a slope ground such as around a dam lake, and a method for producing the same.

[0002]

2. Description of the Related Art In the ground around a dam lake or the like, soil is washed away due to a rapid change in water level, or the water content of the soil changes, which makes it difficult to provide an environment suitable for growing plants. As a result, the plants do not grow and the existing plants die, which causes problems in the natural environment. Further, as described above, since it is generally difficult for plants to grow, the ground is often exposed and the surrounding landscape is often spoiled.

As a greening means for solving these problems, a method of spraying plant seeds directly on the ground has been used. However, there was a low probability that seeds would drop and grow due to abrupt changes in water level. In addition, in order to solve this, a method of directly attaching plants to the ground or a method of transplanting it directly to the ground has been used, but the plants are flooded due to the rise in the water level, or they dry and die due to the decrease in the water level. I couldn't get enough effect.

In order to solve such a conventional problem, Japanese Utility Model Laid-Open Publication No. 4-26237 discloses, as shown in FIG. 7, three layers having a wide flat surface and a vegetation layer 91 enclosing seeds. Layer, the intermediate layer 92 to be a water impermeable layer, and the floating layer 9
A lower layer 3 and a bag 94 that covers and integrates the three layers
And an artificial floating body greening ground 90 having a fixture 95 for fixing to the ground at one end of the bag, according to which a lower layer of the artificial floating body greening ground 90 is a floating layer 93. As a result, it is said that this will rise or fall in accordance with the fluctuation of the water level, and the plants that live will not be affected by being flooded, and the plants can always live on the water surface. In addition, when the artificial floating greening ground 90 is on the water, the water acts to prevent the water from directly touching the roots of the plant by the intermediate layer 92 which is the impermeable layer, and when it is on the bedrock, it is mainly grown by rainfall. Come to do. Further, it is described that a bag made of non-woven fabric can be used to replenish water by utilizing its capillary phenomenon.

[0005]

Conventionally, greening was performed by the above-mentioned method, but there were the following problems.

In Japanese Utility Model Laid-Open No. 4-26237, there is a problem that it is difficult to adjust or change the greening area because it is composed of three layers having a wide plane.

In addition, when the artificial floating greening ground 90 is floating on the water surface, the amount of water taken up is determined by the water permeability of the intermediate layer 92, which is a water permeable layer, and there is a problem that it is difficult to adjust the amount of taken up water.

Further, in the state where the artificial floating greenery ground 90 exists on the rock due to the decrease of the water surface, the above-mentioned wide area of 3
In the layer, water moves to the lower slope of the bedrock,
There was a problem that the water content of the upper part and the lower part of the slope differed greatly.

Similarly, in the state where the artificial greening ground 90 is on the rock, when the water is replenished by the rainwater, the vegetation layer 91 is temporarily moistened, but as described above, the vegetation layer 91 has the above-mentioned large area. There is a problem that water moves to the bottom of the three-layered slope and rainwater cannot be sufficiently stored, and in particular, it cannot be stored evenly over the entire artificial floating greening ground 90.

The present invention has been made to solve the above problems, and is an artificial floating body having a water storage function and a water content adjustment function that are more suitable for being installed on a slope such as the ground around a dam lake. The purpose is to provide a green ground.

It rotates around the upper end side and floats above the water surface, and the other two unit greenery grounds 100 are still placed on the slope of the ground. This is because the adjacent unit green grounds 100 are formed by tacking the rope and the net 61 so that they can be bent together.

From the state shown in FIG. 5, when the water level further rises, the other two unit greenery grounds 100 can also be bent with respect to each other as the water level rises. It further rises while rotating around its upper end side, and as a result, as shown in FIG. 6, all three unit greenery grounds 100 float above the water surface. In the state shown in FIG. 6,
The artificial floating body greening ground 1000 has each unit greening ground 10
0 floats on the surface of the water, and in that state, each unit greenery ground 1
The rope 60 and the net 61 at the upper edge of the side of 00,
Nylon binding belts 62 are bound at several points and connected to each other, and float above the water surface.

As described above, when the artificial floating greening ground is floating above the water surface, each unit greening ground 100 rises or descends as the water surface changes, and the vegetation layer of the unit greening ground The plants will not be flooded under the influence of water surface fluctuations and will not die or die.

When the artificial floating greening ground is on the surface of the water, the rain falling from above causes water to be stored in each unit water-retaining layer 20, and even when there is no rain, the water surface is The water from is supplied to each unit water retaining layer 20 by the water supply sheet 40 exhibiting a capillary phenomenon, and the bottom of the vegetation layer 10, that is, the upper surface of the water retaining pad 21 is constantly kept in a wet state. Therefore, the plant of the vegetation layer 10 of the artificial floating greening ground 1000 does not die and die while floating on the water surface.

When the water surface descends from the state shown in FIG. 6, the reverse operation to that described above has the same effect, and the unit greenery ground 100 is placed on the slope 80 of the ground. 4, even in the state of FIG. 5, in addition to the above action, the bottom of the vegetation layer 10, that is, the upper surface of the water retaining pad 21 is kept steady by the water retained in the unit water retaining layer 20 when the water surface is in a high position. Can be kept in a wet state.

Since the position of the lake surface changes depending on the season or the like, when the artificial floating greenery ground 1000 is to be installed, the lake surface may be high. In this case, the artificial floating greenery ground 1000 should be installed. Of course, this is also possible. In this case, the artificial floating body greening ground 1000
Is floated by pushing the other end from the upper side of the slope 80 toward the lake directly toward the lake, and when the whole floats above the lake, one end of the artificial floating plantation ground 1000 on the front side is fixed. The tool 81 is driven and fixed at a predetermined position on the slope 80.

In the above-described embodiment, the artificial floating body greening ground 1000 is provided by using a plurality of unit greening grounds 100 according to the area to be greened. However, one large area artificial floating greening ground is formed and It is also possible to carry out the greening according to the present invention with the artificial floating greening ground.

When the artificial floating greening ground of a single body formed in this way is used, the labor of binding the unit greening grounds 100 together by a rope can be omitted, and the manufacturing cost thereof can be reduced.

Modification 2 In the above embodiment, the vegetation layer 10
The light-weight artificial soil 11 and the seed-filled sandbag 12 were formed by using a bag made of the non-woven fabric 13. However, the bag used may be wholly or partially exhibiting a capillary phenomenon.

When the vegetation layer 10 is formed in this manner, it is possible to expect a better water absorption effect in the vegetation layer itself.

Modified Example 3. In the above embodiment, the water retention pad 21
Shows an example in which eighteen cylindrical recesses are provided per unit water retention layer, but this may have a rectangular shape or more.

As described above, according to the first embodiment of the present invention, the floating layer 30 made of an integrally molded product of the closed cell synthetic resin foam.
And a unit water-retaining layer 20 having an outer peripheral frame-like portion arranged in a rectangular shape on the floating body layer 30 and having a recess at the bottom thereof.
And a plurality of unit greenery grounds 100 each of which has a required area and is formed by wrapping a greenery ground body consisting of a vegetation layer 10 which is a soil layer enclosing seeds and arranged on the unit water retention layer 20 with a net 61. An artificial floating body greening ground 1000 is formed by arranging in a rectangular shape and tacking the upper side of the edge side surface of each unit greening ground 100 with a rope 60, one end of which floats above the water surface at a rising water surface position and descends. Since the greenery ground is fixed at a position on the slope of the ground such that the greenery ground is mounted on the slope of the ground at the water surface position, the artificial floating greenery ground 1000 can be used when the amount of water in a lake is large. As shown in FIG. 6, the floating layer 30 floats above the water surface by the floating action, the vegetation layer 10 is constantly maintained on the water surface, and the vegetation layer 10 is submerged in water due to the fluctuation of the water level. By, or seeds outflow of vegetation layer, also can be eliminated that the plant itself their growth is inhibited by soaking in water.

Further, even when the water level is lowered, as shown in FIGS. 4 and 5, the water is retained in each unit water retentive layer 20 which is divided into small parts, and is further sucked up from the rainwater or the water supply sheet 40. Due to the water-storing action that takes the water flowing through the bedrock into the water retaining layer 20 when it rains, the water in the upper layer does not run out, and the plants in the upper layers can grow the vegetation layer 10 satisfactorily and can vegetate well. .

By such a floating action and a water retention action, it is possible to suppress the fluctuation of the water content of the vegetation layer 10 due to the fluctuation of the water level and further the dying of the vegetation layer due to the fluctuation of the water content, and the fluctuation of the water level of the dam lake It has the effect that you can always create a green zone on the water surface without being affected by it.
