DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitting fence for wave-resistant vegetation for vegetation on a flooded slope such as a reservoir or a river such as a dam lake.
In respect, in particular, those related wave such as reservoirs and rivers, such as a dam lake, the vegetation knitting fence that was to be able to eliminate the adverse effects on the plant base by water flow and the like.

[0002]

2. Description of the Related Art Reservoirs such as lakes and ponds represented by dam lakes,
Alternatively, in a river or the like, a so-called “flooded slope” (a slope near the water surface) always exists around the river. This “flooded slope” may become completely dry or submerged when the water level of reservoirs such as dam lakes and rivers fluctuates due to seasonal changes and the amount of water storage. In other words, the flooded slope around the reservoir, such as the lake shore of the dam, is an environment in which sufficient growth of plants cannot be expected as it is. It is in a state of having been done.

[0003] In other words, this flooded slope is susceptible to erosion by water currents and waves, especially if it is made of soft rock, and its sediment tends to flow down to the lake bottom of the dam. I have. In order to prevent this erosion, prevent the deterioration of the water storage function due to sedimentation, actively purify the water quality and prevent turbidity, and protect the landscape of the dam lake, which has recently become a tourist destination From the viewpoint of flooding, it is necessary to proactively implement greening of environmental forests and grassland formation, including the lakeside shore, in accordance with the environmental conditions of the flood slopes of reservoirs such as dam lakes. No.

[0004] On the other hand, the water level of a reservoir such as a dam lake varies in meters due to the four seasons and the drought season, particularly due to the drought year and the difference in the storage management method.
The flooded slope has a large area. In other words, the “flooded slope” of a reservoir such as a dam lake may be completely exposed from the lake surface and become dry due to a large change in the lake level. It is a harsh condition.

For such flooded slopes under severe conditions, for example, a vegetation method called a "floating island" method has conventionally been employed. This floating island construction method establishes vegetation on a "floating island" that moves up and down the lake surface, and protects the landscape with the vegetation on this floating island, but the construction cost is extremely high In addition to direct placement on sloping slopes with vegetation ,
No therefore, it was not intended to construction for the purpose of achieving sufficient stability of the water deaths slopes.

For this reason, for example, Japanese Unexamined Patent Application Publication No.
A greening method has been developed as proposed in the publication. According to the tree planting method described in the claims of the above publication, as shown in FIG. 5 , "a nonwoven fabric bag is stored in a plastic or metal net basket, and a vegetation base material is placed inside the bag. A dam lake, characterized by continuously installing filled greening boxes on the bare slopes of flooded surfaces such as dam lakes, lakes and ponds, and planting amphibious plants in the greening boxes .
The method of stabilizing and reclaiming the slopes of lakes and ponds, etc.

[0007] The tree planting method proposed in this Japanese Patent Application Laid-Open No. 6-322731 is as follows. To be more buffered and overcome.・ Plant plants that can withstand repeated flooding and nakedness of dam lakes, lakes, ponds, etc., and their roots come out of the greening box and invade the slopes behind them to stabilize the ground for a long time. -Use plants to make the landscape of dam lakes, lakes, ponds, etc. permanently compatible with the surrounding environment. It is considered that these objectives have been achieved. However, since the "greening box" has to be adopted, it still includes the following points to be improved.

In other words, flooded slopes in reservoirs such as dam lakes, ponds and rivers are washed by waves,
Failure to suppress the power of this wave will not only result in the escape of the base material contained in the "greening box", but will also limit growth by exposing and damaging the roots of the plant. Of course, this type of "greening box" must be easy to construct. Inundation slopes are often difficult to bring in materials, and in particular, there is a trail around Dam Lake, but there is no way to the opposite shore, and steep slopes formed by rock excavation, Because there are slopes of concrete structures, it is not only difficult to grow plants, but also difficult to construct. Especially in reservoirs such as dam lakes,
Water stagnation and influx of eutrophic water from the upstream basin must prevent eutrophication of water as much as possible.
Water pollution causes fish and the like in reservoirs such as dam lakes to die due to lack of oxygen, and water turbidity by blue-green algae damages the landscape.

Therefore, the present inventors have studied how to improve the above-mentioned item (1) when greening a flooded slope in a reservoir or a river such as a dam lake in consideration of the environment. As a result of various studies, the present invention has been completed.

[0010]

SUMMARY OF THE INVENTION The present invention has been made on the basis of the above-mentioned background, and the problem to be solved is to solve the problem of sediment loss on a flooded slope such as a reservoir such as a dam lake or a river. Effective prevention and establishment of vegetation, durable,
The aim is to stabilize the topsoil and surface ground by early greening.

[0011] Sunawa Chi, where the book onset Ming purposes,
Easy installation of manufacturing and using the same, and can be performed reliably protect the growth base material or plant, suitable for carrying out greening waterlogging slopes such as reservoirs and rivers such as dam vanishing It is an object of the present invention to provide a knitting fence for wave resistant vegetation.

[0012] Also, it is an addition to the purposes of the present invention,
By joining the land and the flooded surface to achieve consistent vegetation, erosion due to waves and water currents can be sufficiently prevented after construction, construction is easy, and plant growth is maintained and maintained. and can be, there is a can that wave-dissipating fluid-tight speed vegetation knitting fence also be carried out in the formation and recovery of the biotope to be subjected Hisage <br/>.

[0013]

In order to solve the above problems BRIEF SUMMARY OF THE INVENTION, means of adopting the present onset Ming is explained with reference numeral used in the description of embodiments below, "the dam or the like It is installed on flooded slopes 40 such as reservoirs and rivers, and is used when vegetating the flooded slopes 40. Net materials, bamboo materials, etc.
The formation of the substantially box-like shape upwardly is released to open by the elastic material
A vegetation knitting fence 10, the vegetation knitting fence 10,
At least the front surface has irregularities 11a.
Wave-resistant flow surface 11 and water-soluble membrane 2 disposed on the inner front surface
1 and the flooded slope 40, which was put into the water-soluble membrane 21.
Seeds and land of plants that can grow and proliferate in the water level fluctuation area
Plant cells such as lower stem, root system, shredded trunk or cuttings
Section 30, and soil, sandy soil, latent topsoil, local root soil
Culture materials 31 such as soil and soil materials that contribute to water purification
And these plant cell sections 30 and culture soil material 31
Erosion or scouring-resistant thick layer material formed by spraying
Composed of spraying layers 32 of various spraying materials, such as materials and landslide materials
Then , the knitting fence 10 for vegetation is fixed to the flooded slope 40 and to the fixed pile 22.
Therefore, the wave-damping-resistant vegetation knitting fence 10 "is directly fixed .

That is, the wave-breaking knitting fence 10 for withstanding current velocity vegetation.
Is different from the conventional greening box shown in FIG. 5 in that it has a wave-breaking flow-resistant surface 11 having at least a front surface with irregularities 11a. That is, the impact of the waves hitting the slope 40 is reduced to cancel the waves. In other words, the wave-damping flow-resistant vegetation knitting fence 10 is entirely formed of an elastic material such as a net material and a bamboo material, and as shown in FIG. It is installed on the flooded slope 40.
Due to the unevenness 11a formed in 1, the wave complicates and reflects on the knitting fence 10 for wave-damping resistant vegetation and is also wave-dissipated by the mesh. The force by the waves does not enter the knitting fence 10.

Further, since the force of the waves does not enter the wave-breaking speed-resistant vegetation knitting fence 10, the growth points of the plants are directly protected, and the uprooted roots are washed away by the waves or the flow during the growth of the plants. Do not damage or damage.

The knitting fence 10 for wave-dissipation-resistant vegetation is:
Since it is formed in a substantially box shape by an elastic material such as a net material and a bamboo material and is opened upward to form the upper opening 12, not only the whole is easily manufactured but also the plant cell section 30 and The injection of the culture soil material 31 and the spraying operation for forming the sprayed layer 32 can be easily performed from the upper opening 12.

As an elastic material such as a net material and a bamboo material for forming the wave-breaking-speed-resistant vegetation fence 10, water from a lake or the like must penetrate therethrough. Since it is necessary that the material 30 and the cultivation soil material 31 can be prevented from flowing out of the knitting fence 10 for wave-dissipation resistant vegetation as much as possible, a mesh of 10 to 40 mesh is suitable. Moreover, since the wave-breaking speed-resistant vegetation knitting fence 10 itself needs to have durability, the elastic material such as the net material and the bamboo material is, of course, metal.
It is preferable that it is made of a synthetic resin having excellent corrosion resistance.

Then, in order to prevent the culture soil material 31 from leaking out during the period until the plants incorporated in the wave-breaking speed-resistant vegetation knitting fence 10 emerge, as shown in FIG. A water-soluble film 21, for example, water-resistant paper or sheet, is arranged inside the wave-damping and current-resistant vegetation fence 10
is necessary. It is preferable that the water-soluble film 21 is a structure that can be melted by water eventually, the water-soluble film 21 is broken by the growth of the plant, and the plant can protrude to the outside of the wave-damping resistant vegetation fence 10.

[0019] These each wave-dissipating fluid-tight speed vegetation knitting fence within 10 to
Are plant cell sections 30 such as seeds, rhizomes, root systems, shredded trunks, or cuttings of plants that can grow and proliferate in the water level fluctuation region of the flooded slope 40, and soil, sandy soil, latent topsoil, Culture soil material 31 such as local root soil and soil material that contributes to water purification is supplied . On the surface of that, resistance to erosion or wash moat of thick layer materials, the spray layer 32 is formed by blowing the various spraying materials such as soil dressing materials, plant cell pieces 30 and potting This spraying layer 32 Material 31 waves, is to Runode so as not washed away by the water flow or the like.

[0020] In other words, for the wave-dissipating fluid-tight speed vegetation of this Hen fence 10
After the plant cell section 30 and the cultivation soil material 31 are put into the inside, various spraying materials such as erosion-resistant or scouring-resistant thick-layer material, customer soil material, etc. are sprayed on these surfaces to form a spraying layer 32. than is that to form.

The formation of the sprayed layer 32 by spraying various growth base materials on the surfaces of the plant cell sections 30 and the culture soil material 31 in the wave-damping-resistant vegetation fence 10 is performed according to the wave-damping-resistant vegetation. It may be either before or after the installation of the knitted fence 10 on the flooded slope 40. In other words, if the flooded slope 40 is shaped like a steep cliff, the plant cell section 30 is placed in advance in each of the wave-dissipation-resistant vegetation knitting fences 10 on the ground.
And culture soil material 31 was charged in advance by forming a spray layer 32 thereon, which may be coupled a rope or expand the coupling rope or net from above the submerged slopes 40 linked to net . In addition, the knitting fence 10 for lowering the wave breaking speed
The spraying layer 32 may be formed in advance also in the case where is installed below the normal water level in FIG. On the other hand, for the flooded slope 40 which is not too steep and which can spray various spraying materials such as a thick base material and a soil material, the plant cell section 30 and the culture soil material 31 are put in advance on the ground. After installing each of the wave breaking resistant flow rate vegetation knitting fences 10, the spray layer 32 may be formed on the flooded slope 40 together with the inside of each wave breaking resistant flow rate vegetation knitting fence 10. It is.

[0022] is adopted here, the plant for taking a plant cell pieces 30 having buds, those which upon drying also Ikinagaraeru even when submerged well, growing wild mainly submerged slopes 40 Are suitable. Specific examples include willows, water madder (meriken mugura), bovine nosipei, horsetail, seri, dokudami, and other water-resistant plants that can coexist with them. And this plant cell section 30
As a matter of course, not only the above-mentioned plant seeds but also the flooded slope 4
A rhizome, a root system, a shredded trunk, a cutting, or the like of the plant capable of growing and proliferating in the water level fluctuation region of 0 can be adopted.

[0023] In addition, as a culture soil material 31, which is adopted here, soil dressing, such as described above, sand soil, although the potential topsoil or the like is adopted, local root system soil, in other words flooding of the construction site If a plant is growing on the slope 40, the local soil is suitable as the culture soil material 31, and it is natural to adopt such a local root system soil as the culture soil material 31.

A mixture of a growth base material and a water purification material is suitable for various spraying materials such as a thick base material and a soil material for the spraying layer 32. As the growth base material in this case, rock wool and peat moss as main materials can be considered. Further, as a water purification material, a material mainly composed of zeolite, particles, carbon particles, lime particles, and Kanuma earth particles can be considered.

These growth base materials and water purification materials are as follows:
This not only promotes the germination and growth of the plant cell section 30, but also is not at all a factor of eutrophication. In addition, these growth base materials and water purification materials also have a function of capturing nutrients in wastewater flowing from above, and are useful for preventing pollution of lakes and rivers. On the other hand, if it is a so-called general growth base material,
It contains fertilizer components contained in composts such as nitrogen and phosphoric acid, and causes eutrophication of water. Therefore, the present invention does not include such general growth base materials.

[0026]
