Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterside greening method. Here, the water's edge is, for example, a river or lake, or
It refers to watersides such as reservoirs, dam lakes, and reclaimed water reservoirs.

[0002]

Background of the Invention Generally, at the water's edge, a slope is often formed by spraying mortar, concrete, etc., or laying a concrete block. On this slope, almost all plants are grown. There is no so-called plant growth slope, so the landscape is a scarce landscape with poor green.

In recent years, rivers, lakes and marshes have been polluted by industrial wastes, domestic wastewater, etc., but water such as water dammed up by reservoirs and dams or water stored in reclaimed land ponds, etc. The stagnant water inhabits there because the water is stagnant compared to the water in rivers, etc., and pollution is likely to proceed and it is difficult to purify, and the quality of the water is degraded. The number of seafood and plant varieties is gradually decreasing, and some are endangered. Then, due to the deterioration of the water quality of the reservoir in this way, the scenery around it deteriorates, and the destruction of nature gradually progresses.

[0004]

In order to solve these problems, it is necessary to make the landscape more natural and beautiful by linking planting difficulty slope slope greening, water purification, and landscape beautification to one another. At present, almost no comprehensive greening measures have been taken.

The present invention has been made in consideration of the above matters, and not only improves the water quality, but also improves the quality of the surroundings of the improved water, especially by vegetation on the slopes where plant growth is difficult. The purpose is to provide a useful waterside greening method that matches the landscape and beautifies the landscape.

[0006]

In order to achieve the above-mentioned object, the first water-side greening method of the present invention uses a bag-shaped mat in which a plant growth substrate such as a plant seed and a fertilizer and a water purification agent are used as a filling material. While accommodating, vegetation mats with floats attached to the bag-shaped mats may be laid on a slope where water plant growth is difficult, such as in rivers and lakes, with some of them floating on the water surface. It has a feature. In this case, an aquatic plant having a water purification function may be planted on the vegetation mat.

The second waterside greening method of the present invention is
In a double-structured bag, a plant growth substrate such as fertilizer and a water purification agent are stored as a filling material, an aquatic plant having a water purification function is planted in this bag, and a float is attached to the bag. A plurality of vegetation mats are laid on rivers, lakes and marshes on slopes where it is difficult for plants to grow, with some of them floating on the surface of the water.

Further, in the above-mentioned waterside greening method of the first invention, the float may be housed in the vegetation mat, or the float may be attached to the vegetation mat.

Further, in the above-mentioned waterside greening method of the second invention, it is preferable that the float is attached to the vegetation mat.

[0010]

The operation of the above-mentioned first waterside greening method is as follows. In a plurality of bag-shaped mats, plant seeds such as lead canary and weasel, plant growth substrates such as peat moss and bark compost, appropriate fertilizers, water retention agents, and water purification agents such as activated carbon, zeolite, and coconut husk charcoal. A vegetation mat is constructed by appropriately mixing and injecting the mixture as a filling material using a dry spraying machine such as an aeroceder, and by providing a float made of, for example, Styrofoam, to an appropriate one of these bag-shaped mats. Then, a plurality of vegetation mats configured in this manner are laid on, for example, a slope on the waterside of a river where plant growth is difficult so that part of the vegetation mat floats on the water surface.

Since the bag-shaped mat of the vegetation mat contains a plant growth substrate such as a fertilizer or a water retention agent for assisting the growth of plants, the germinated plant seed absorbs and grows these, and the vegetation mat Grow as a growth base. Then, some of the bag-like mats float on the water surface due to the float, but since the water-purifying agent is contained in these bag-like mats, water is purified by the water-purifying agent.

Therefore, a plant grows from the plurality of bag-like mats laid on the slope and the plurality of bag-like mats floating on the water surface, thereby greening the water's edge and the water surface. Then, the water is purified by the water purification agent contained in the plurality of bag-shaped mats floating on the water surface. Greening of slopes and water facing slopes are purified, and plant growth difficult slopes are greened, water is purified, and scenery is beautified all at once.

[0013] In the above first waterside greening method, when an aquatic plant having a water purifying function such as auction, watercress, color and ivy is planted in the bag-shaped mat, the plant seeds housed in the bag-shaped mat are planted. During the period from germination to growth of plants, plant growth difficulty slopes are greened and water is purified more.

In the second water-side greening method, since plant seeds are not placed in the vegetation mat, the greening is inferior to the first water-side greening method, but the slope is more excellent than the conventional method. The effect of surely greening and purifying water is extremely large.

In each of the above-mentioned first and second shoreline greening methods, since the vegetation mat soaked in water floats on the water, the plant seed in the vegetation mat causes root rot. , The sprouted plant or planted plant is not soaked in water to cause root rot.

The vegetation mat 1 is a bag formed by double weaving corrosion-resistant yarns T ₁ and T ₂ and interwoven, and having a pair of front and back net-like bodies based on the ground portion having a vegetation region 2. Shaped mats 3 are connected to each other, and a plant growth base such as plant seeds and fertilizers and a water purification agent are introduced into the bag shaped mat 3 from its opening 3a by a nozzle 4 of a dry spraying machine (not shown). While the bag-shaped mat 3 is filled with the filling material 5, the bag-shaped mat 3 contains a rod-shaped float 6 made of a material such as Styrofoam whose specific gravity is considerably smaller than that of water.

That is, in the bag-shaped mat 3, the corrosion-resistant thread T ₁ is connected to the bag-shaped mat 3 in the connecting direction (direction A in FIG. 3).
And a reinforcing portion 7 formed by continuously weaving a narrow reinforcing band 7a in a direction orthogonal to the connecting direction A (direction B in FIG. 3) in a grid pattern at predetermined intervals in both directions A and B. The squeezing portion 8 arranged by weaving the positions where the reinforcing strips 7a intersect with each other is formed in a net-like body. Such a bag-shaped mat 3 is connected through a narrow partition 9 to form the vegetation mat 1,
Both ends 1a of the vegetation mat 1 in the A direction are woven in a single layer to form the ears 10, and a thread having a thickness of 500 to 1000 denier is further used as the corrosion resistant thread T of the ground portion.
_The vegetation region 2 surrounded by the reinforcing portion 7 by arranging 50 to 80 pieces of the corrosion-resistant yarn T ₁ for each of _{1 and} T ₂ within 7 cm.
To form.

Further, in interweaving the corrosion resistant yarn T ₁ with the corrosion resistant yarn T ₂ , as shown in FIG.
Corrosion resistant yarn T having a thickness of 00 to 1000 denier
₂ is woven in a grid pattern in the A and B directions and has a width h of 1
The reinforcing band 7a having a width of 3 cm is formed.
7a forms a reinforcing portion 7 of a lattice frame having a length m and a width n of 7 to 10 cm.

The partition 9 and the ear 10 are also 500 to 10.
It is formed of a corrosion-resistant thread T ₂ having a thickness of 00 denier, and the reinforcement portion 7, the partition portion 9, and the ear portion 10 secure the strength of the vegetation mat 1 during construction and press-fit the filler 5. While maintaining the bursting resistance of the filling material 5 at the time of filling, the strength of the vegetation mat 1 and the form of the vegetation mat 1 after the corrosion of the corrosion resistant thread T ₁ constituting the vegetation region 2 are ensured for a long time, and the bag shape The flow of the filling material 5 filled in the mat 3 is prevented.
The reinforcing portion 7, the partition portion 9, and the ear portion 10 are made of the corrosion-resistant thread T.
_A large number of ₂ are gathered and woven with high density to obtain high strength.

The corrosion-resistant yarns T _{1 and} T ₂ used for forming the vegetation mat 1 are made of polyester, polyamide, polyethylene, nylon, vinylon, etc., which are excellent in environmental resistance, in order to prevent them from being sucked out by water for a long period of time. Chemical fibers are suitable.

The filling 5 filled in the bag-shaped mat 3 of the vegetation mat 1 constructed as described above will be explained. As the plant seed, seeds such as reed canary and weasel are suitable, and As the plant growth base material, peat moss or bark compost is mainly mixed with an appropriate fertilizer and a water retention agent in an appropriate ratio, and as the water purification agent, activated carbon, zeolite or coconut husk charcoal is used. Then, the plant seed, the plant growth base material and the water purification agent are appropriately mixed to form the filling 5.

The float 6 is made of, for example, Styrofoam, and is formed into a rod-shaped body having a diameter of 6 to 10 cm and a length of about 1.5 m. However, the float 6 is not provided in all the bag-shaped mats 3. For example, they are provided at a pitch of 40 cm.

The vegetation mat 1 has, for example, a width of 1.6 m, a length of 5 to 10 m, and a thickness of 15 cm. In FIG. 2, 11 is an eyelet formed on the uppermost bag-shaped mat 3.

As shown in FIG. 1, the vegetation mat 1 constructed in this way is, for example, a concrete block 1 for a river.
The vegetation mat 1 is fixed by inserting the anchor pin 14 into the eyelet 11 which is laid on the slope 13 formed by laying 2 and is formed on the uppermost bag-shaped mat 3. In this way, a plurality of vegetation mats 1 are laid on the slope 13 and the slope 13 is entirely covered. In this case, since the float 6 is stored inside the bag-shaped mat 3 on the lower end side of the vegetation mat 1, that is, the bag-shaped mat 3 near the position in contact with the water 15, as shown by the phantom line. If the water surface 15a rises, it will float on the water surface 15a.

Since the bag-shaped mat 3 of the vegetation mat 1 laid on the slope 13 as described above contains the plant growth base material such as fertilizer and water retention agent for assisting plant growth, germination has occurred. Plant seeds absorb and grow these, and grow using the vegetation mat 1 as a growth base. Then, the bag-shaped mat 3 at the position in contact with the water 15 floats on the water surface 15a by the float 6, but since the water-purifying agent is contained in these bag-shaped mats 3, the water-purifying agent causes Is purified.

Therefore, plants 16 grow from the plurality of bag-like mats 3 laid on the slope and the plurality of bag-like mats 3 floating on the water surface 15a, whereby the waterfront and the water surface 15a are greened. Then, the water 15 is purified by the water purification agent contained in the plurality of bag-shaped mats 3 floating on the water surface 15a. In this way, the slope 13
The greening and water on the slope 15 are purified, and the slope 13 where plants are difficult to grow, the water 15 is purified, and the landscape is beautified all at once.

In the above-mentioned embodiment, the bag-like mat 3 constituting the vegetation mat 1 is provided with the floats 6 at a pitch of 40 cm, but as shown in FIG. 5, it is close to the water 15, that is, the bottom end. The float 6 may be bound to the lower end of the bag-shaped mat 3 by using an appropriate fastener 17, for example. In this case, it is desirable for the float 6 to have a larger buoyancy.

FIG. 6 and FIG. 7 are views showing another embodiment of the first waterside greening method. In this embodiment, as shown in an enlarged view in FIG. 6, a cross-shaped cut 18 is formed on the upper surface of the bag-shaped mat 3 so that an appropriate opening 19 can be formed, and as shown in FIG. Aquatic plants 20 having a function of purifying water quality such as agar, watercress, color and ivy are planted on the bag-shaped mat 3 via 19. The aquatic plant 20 may be a seedling or one that has grown to some extent.

In this case, the slope 13 and the water surface 15a are greened and the water 15 is purified more until the plant seeds housed in the bag-shaped mat 3 germinate and grow. Be seen.

Next, the second waterside greening method of the present invention is
This will be described with reference to FIGS. In these figures, 21 is a vegetation mat used in the second waterside greening method, for example, a fabric 22a having water permeability and a non-woven fabric 22b made of a material having corrosion resistance are overlapped, and the non-woven fabric 22b is placed inside. A support frame (not shown) made of, for example, a synthetic resin for retaining its shape is provided in the bag 22 having a double structure configured to be positioned, and a plant growth substrate such as fertilizer and water purification. While containing the agent as a filling 23, an aquatic plant 24 having a water purification function is planted in the bag 22 and a float 25 is attached to the end thereof.

The plant growth base material and the water purification agent constituting the filler 23 filled in the bag 22 are the same as the plant growth base material and the water purification agent used in the first waterside greening method. , Its detailed description is omitted. Then, as shown in FIG. 10, a cross-shaped cut 26 is formed in the bag 22 so that an appropriate opening 27 can be formed.
Aquatic plants 24 having a function of purifying water quality such as agar, watercress, collars and ivy are planted on the vegetation mat 21 through the openings 27. The aquatic plant 24 may be a seedling or one that has grown to some extent.

The vegetation mat 21 is provided with hooks 28 at two locations on one side of the four corners of the bag 22, and hook holes made of a reinforcing ring are provided at two locations on the side opposite to the sides. 29 is provided, and the hook 28 is attached to another bag 22.
The vegetation mat 21 can be connected one after another as shown in FIG.

The bottommost vegetation mat 21 of the vegetation mat 21 has a float 25 made of the same material as that of the float 6 attached to a bag 22, for example.

The vegetation mat 21 thus constructed is
It is attached to the slope 30 as follows. That is, the slope 28 of the uppermost vegetation mat 21 is formed by hooking its hook 28 on an appropriate fixing member (not shown).
(In this case, the soil). Next, with respect to this vegetation mat 21, the hook 28 of the second vegetation mat 21 is inserted into the hook hole 29 of the uppermost vegetation mat 21. Hereinafter, this is repeated and the vegetation mat 21 is spread over the entire slope 30.

In this case, the vegetation mat 21 on the lower end side, that is, the near vegetation mat 21 at the position in contact with the water 15
Since the float 25 is attached to, the plurality of vegetation mats 21 will float on the water surface 15a when the water surface 15a is at the position shown by the solid line. And vegetation mat 2
1 has a double structure in which the bag 22 is superposed with a water-permeable cloth 22a and a non-woven fabric 22b made of a material having corrosion resistance. It is effectively prevented from flowing out.

In this second waterside greening method, since plant seeds are not stored in the vegetation mat 21, the greening is inferior to that in the first waterside greening method, but the slope 13 compared to the conventional method. The effect of more surely greening and purifying the water 15 is extremely large.

In FIG. 8, reference numeral 31 is a sheet made of rubber or plastic, which is interposed between the slope 30 and the vegetation mat 21. By doing so, the roots of the aquatic plants 24 in the vegetation mat 21 are sloped 30.
Is prevented from entering the soil. In addition, when the slope 30 is made of the concrete block 12 like the slope 13 on which the first waterside greening method is applied, the sheet 3 is used.
It is not necessary to provide 1.

By the way, the water purification agent used in each of the above-mentioned examples has a reduced purification effect due to clogging or the like. Therefore, it is good to replace it in about one year. Then, the used water purification agent can be reused for the grass soil or the like.

[0040]

As described above, according to the present invention, it is possible to surely carry out the greening at the water's edge, which is impossible by the ordinary greening method such as the conventional spraying method. And
Since the vegetation mat contains a water-purifying agent for purifying water together with a plant growth substrate for favorably growing plants, growth of aquatic plants, that is, greening and water purification can be performed at the same time. In addition, since the vegetation mat is provided with a float and the vegetation mat soaked in water is configured to float on the water, the plant seed in the vegetation mat causes root rot, sprouted plants or planting. There is no chance that rooted plants will be soaked in water.

That is, according to the waterside greening method of the present invention, the greening of the slope and the water facing the slope are purified, and the greening of the slope where plant growth is difficult, the purification of water, and the beautification of the landscape are achieved all at once. .
