Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a greening ground that artificially promotes greening on the ground around a dam lake where it is difficult to green the rocks.

<Prior art> In the ground around dam lakes, it is often seen that the soil is washed away due to a sudden change in water level and the ground is exposed.

Generally, it is difficult to plant trees around the dam lake where the ground is rock, and the exposed ground remains as it is.
There are many cases where it damages the surrounding scenery.

Although dam lakes, etc. themselves become new tourism resources, they also cause natural environmental problems such as the surrounding mountains being flooded and the trees and flowers that have been used up to die.

Conventionally, the following measures have been taken as means for solving these problems.

(B) A method of directly spraying seeds and the like onto the ground.

(B) A method of directly gluing vegetation on the ground.

(C) Method of transplanting directly to the ground.

<Problems to be Solved by the Present Invention> The conventional greening method as described above has the following problems.

(A) All of the above-mentioned three conventional means are for directly treating the ground.

However, water level fluctuations in artificial lakes such as dam lakes are extremely severe.

Therefore, the artificially sprayed seeds, transplanted plants, and the like have a high possibility of being washed away together with the soil.

(B) When the water level in the dam lake increases, the plants come into direct contact with the water.

Therefore, in order to live in such a place,
The plant must be able to live both underwater and on land.

However, there are almost no plants that can live in water or on land.

The roots of plants under the water (underwater) are in the same state as hydroponics because hair roots are not generated.

However, plants that live in hydroponics are extremely vulnerable to drought.

Therefore, the lifespan of the plants grown in the flooded state placed on the bedrock in the dry season is short, and it is impossible to maintain long-term greening.

Further, even if there are plants that can live under both water and land conditions, application to this area is not preferable because the surrounding plant ecosystem is maintained.

<Purpose of the present invention> The present invention has been made to solve the above problems, and an object thereof is to provide an optimal greening ground for the ground around the dam lake.

<Means for Solving the Problem> That is, the present invention is composed of three layers having a wide flat surface, the uppermost layer serving as a vegetation layer enclosing seeds, the middle layer serving as a water impermeable layer, and the lower layer serving as a floating layer. And the artificial floating greening ground, which has a bag that covers and integrates the three layers, and a fixing member that is fixed to the ground at one end of the bag.

<Structure of the present invention> Hereinafter, the present invention will be described in detail.

(A) Overall configuration The floating greening artificial ground 1 of the present invention is configured by integrating wide planar bags in three layers.

The upper bag 2 is a bag formed in a wide flat shape with soil, peat,
A vegetation layer containing a mixture of various seeds and solid synthetic fertilizer.

The intermediate bag 3 is a flat bag having the same area as the upper bag 2, and is a water-impermeable layer containing a mixture of foamed polystyrene beads and a mixture of earth and sand, peat, wood chips, fibers, cement and the like.

The lower bag 4 is a flat bag having an area substantially the same as that of the upper bag 2 and the intermediate bag 3, and is a floating layer containing light-weight materials such as foamed polystyrene beads therein.

(B) Upper bag The upper bag 2 has a wide planar shape and is mainly made of vinyl, cotton, non-woven fabric or the like, and the culture soil mixed with solid synthetic fertilizer such as soil, peat and seeds is mixed therein.

Therefore, the upper bag 2 serves as a vegetation layer for growing mixed seeds.

When a sealing member such as vinyl is used for the upper bag 2, a plurality of holes through which plants can grow are provided on the upper surface of the upper bag 2, and a plurality of holes for water permeation are provided on the bottom surface.

(C) Intermediate bag An intermediate bag is provided below the upper bag 2.

The intermediate bag is a wide flat bag whose area is almost the same as the upper bag 2, and inside the bag is foam polystyrene beads, earth and sand,
Put peat, sawdust, fiber, cement, etc.

The intermediate bag 3 is configured to have a water permeability coefficient of about h = 10 ^-2 to ^-5 cm / sec.

Therefore, the middle bag serves as a water impermeable layer that is adjusted so that the plant roots of the upper bag 2 at the upper portion do not come into direct contact with water.

When a sealing member such as vinyl is used for the intermediate bag 3, a plurality of water permeable holes are provided on the upper surface and the lower surface of the intermediate bag 3.

(D) Lower Bag A lower bag 4 is provided below the intermediate bag 3.

The lower bag 4 is a wide flat bag having an area substantially the same as that of the upper bag 2 and the intermediate bag 3, and a foamed polystyrene bead or the like, which is a lightweight member, is put therein as a floating body source.

When a sealing member such as vinyl is used as the material of the bag, a plurality of water permeable holes are provided on the upper surface and the bottom surface of the lower bag 4.

The weight of the three layers described above is, for example, such that the upper bag 2 (layer), which is the vegetation layer of the artificial ground, is above the water surface.
2: The ratio of the intermediate bag 3: the lower bag 4 is 1: 0.5: 2.5 to 1.2.

Under this ratio, the lower bag 4 has a floating force and lifts the upper bag 2 and the intermediate bag 3 above.

(E) Cover 5 The cover 5 is a wide flat bag that covers the upper bag 2, the intermediate bag 3, and the lower bag 4.

The cover 5 is made of mesh, non-woven fabric, synthetic resin, vinyl or the like.

When the cover 5 is made of a sealing member such as vinyl, the cover 5 has a top surface and a bottom surface, that is, a plurality of holes for growing plants on the upper bag 2 and a plurality of water permeation holes on the lower surface. .

(F) Fixing member The fixing member 6 is a known member such as an anchor, and is provided at one end of the artificial floating body greening ground of the present invention.

<Operation of the Invention> The operation of the invention will be described in detail below.

(B) Arrangement Arrange a plurality of completed greening grounds according to the greening area.

After the arrangement, the greening grounds are connected by a known connecting means such as a pin.

(B) Installation Move the greening ground, in which seeds have been mixed and mixed in advance, to the installation location, and turn one end with the fixing member 6 toward you and the other end toward the front.

Then, install the green ground by pushing it towards the lake,
At the point where the whole has entered the lake, the fixing member 6 at the front end is driven into the ground.

Therefore, the driving point of the fixing member 6 is underwater,
Drive into the shallow water taking into consideration that the upper bag 2 of the green ground is exposed to the water surface.

(C) Floating The non-fixed part of the greening ground is floated to the extent that the upper bag 2 is exposed by the floating action of the lightweight material of the lower bag 4.

<Other Examples> Other examples will be described below.

(Other Example 1) It is possible to use the bag to be used wholly or partially such that it causes a capillary action such as non-application.

(Other Embodiment 2) A plurality of greening grounds are used according to the area to be greened, but it is also possible to form one greening ground large and implement it as a single unit.

(Other Embodiment 3) When a sealing member such as vinyl is used for the cover 5 and each bag, it is possible to obtain a water permeation effect from the side surface by opening by opening a hole in the side surface.

 Further, the side surface and the bottom surface may be opened at the same time.

<Effects of the Present Invention> According to the present invention, the following effects can be obtained.

(A) The bottom of the artificial floating greening ground of the present invention is a floating layer.

Therefore, the floating greening ground will float or descend as the water level fluctuates, and plants that live will be submerged and will not be affected.

Therefore, regardless of fluctuations in the water level of the dam lake, green areas can always be created on the water surface.

(B) When the water level is low, such as during the dry season, it is placed on rock.

However, the greenery ground of the floating body of the present invention rises or falls depending on the fluctuation of the water level as described above, and the plant always inhabits the water surface.

Therefore, even if it is placed on the bedrock, the condition that it is on the water does not change much.

(C) Plants in the upper layers grow mainly from rainwater.

In the present invention, it is also possible to supply water by using the bag to be used wholly or partially, such as non-woven fabric, which has a capillary action.
