Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to concrete-processed slopes, roofs and walls of artificial structures, median strips of highways, soils and rocks where plant growth is not possible, and it has been difficult to revegetate them. The present invention relates to a vegetation substrate and a greening system used for greening an exposed area.

[0002]

2. Description of the Related Art In recent years, as urbanization has advanced, the rise in temperature, which is observed in the heat island phenomenon, and the accompanying environmental destruction have become serious problems. Demand for greening, which has been used to improve the scenery by applying greenery to the walls and rooftops of artificial structures that have a murderous landscape, is rapidly increasing. For example, in Tokyo, the rooftop is obliged to be green in order to reduce the temperature and reduce the heat island phenomenon by greening the rooftop. In addition, vegetation is required from the aspect of landscape and environment for slopes that require concrete treatment for rockfall prevention and earth stoppage, such as quarry sites in the mountains and slopes formed by land reclamation. As demand increases rapidly, expectations for better greening technologies continue to grow. Recently, as a method of greening artificial structures, a method of spraying the soil with a machine and a method of sticking a mat-shaped combination of a thin soil plate and a drought-resistant plant are often used. There are many problems in terms of survival rate and growth rate.

[0003] Since spray greening using a machine is simple and inexpensive to construct, it is effective and effective for particularly large-scale public works, but usable soil is a breeding material. However, there is a problem in that the number of plants to be used is limited, especially when the plant is a part or the whole of the plant, because it is limited to a soft one that does not damage the machine and the propagation material. Grass is generally used for spraying, but grass requires a certain amount of soil from the viewpoint of water and fertilizer, and especially in areas where the revegetation target area contains little water such as bedrock, much soil thickness is required. It will be necessary and cost will be proportional to the amount of soil used. In addition, the thick soil causes weeds and other plants to easily infest. In part of the roads and rivers, among the surrounding invading plants, the invasion of pine trees, Japanese pampas grass, etc. cannot be left for disaster prevention, and it is necessary to manage the removal and cutting of the trees. Using drought-tolerant plants that do not require much water or fertilizer is effective as a measure to reduce costs and weeds because soil thickness can be reduced, but high drainage soils suitable for drought-resistant plants are pumice, perlite, and volcanic gravel. Since it is hard, it is not suitable for a spraying machine, and when mixed together in a mixer, it causes damage to plants. In addition, there are two major issues that need to be resolved in the entire greening work. One is a method of revegetation in places where soil where growth of plants is inappropriate such as strongly acidic soil, and another is fire prevention of medium materials, that is, mats for revegetation work in which plants are planted. For example, there is a fire that is currently becoming more serious due to cigarettes being thrown away from the slopes of roads that have already been planted. If it occurs in a place where greening work has been done over a wide area, the damage will be great.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention uses a drought-resistant plant as a plant to be used, which saves management labor such as removal and reaping of invading plants after construction, and We realized mechanical spraying using drought tolerant plants and high drainage soil suitable for it that was impossible until then, and provided a greening system to reduce soil runoff and runoff rate of plant seedlings. The present invention provides a greening system that enables healthy growth of the above-mentioned plants, greening a place having soil unsuitable for plant growth, and a greening system that prevents fires.

[0005]

In the vegetation substrate of the first aspect of the present invention, a net body is used in which soil storage bags are attached in stripes or grids at predetermined intervals. The soil storage bag contains highly drainage soil that is not suitable for spraying because it is hard. The soil storage bag should be made of a mesh that allows the plant root to penetrate without spilling the soil. In the vegetation substrate of the second aspect of the present invention, a three-dimensional lattice net is attached to a space intermediate portion between the soil storage bags of the vegetation substrate. In the vegetation substrate of the third aspect of the invention, a required number of strip-shaped drainage zones are attached in the longitudinal direction of the back surface of the vegetation substrate of the first or second aspect. Claim 4
In the vegetation substrate of the invention of (1), a net body having three-dimensional stitches is used.

In the greening system according to the fifth aspect of the present invention, the vegetation substrate is arranged and fixed on the surface to be greened, and then the breeding material is mixed and sprayed in a soft water-retentive soil suitable for mechanical spraying. In the greening system of the invention of claim 6,
After placing the vegetation substrate on the surface to be planted and fixing it, the propagation material is mixed with non-combustible soil and sprayed. In the greening system of the seventh aspect of the present invention, the propagation material to be mixed with the water-retaining soil or the non-combustible soil is used as a part or whole of the plant body of the drought-tolerant plant or a plant seedling with cultivated soil. In the greening system of the eighth aspect of the present invention, the fixed vegetation substrate is sprayed with only the water-retaining soil to form a growth base, and the vegetative soil portion of the plant seedling with cultivated soil, which later becomes a breeding material, is pushed in by hand for installation. In the greening system according to the ninth aspect of the invention, the fixed vegetation substrate is sprayed with only non-combustible soil to form a growth base, and the vegetative soil portion of the plant seedling with cultivated soil, which later becomes a breeding material, is pushed in by hand to set.

In the greening system of the tenth aspect of the present invention, the root-preventing sheet is installed under the vegetation substrate. In the greening system of the eleventh aspect of the present invention, the water blocking sheet is installed under the vegetation substrate. In the greening system of the twelfth aspect of the present invention, a water blocking layer is provided on the surface to be greened.

[0008]

According to the vegetation substrate of the first aspect of the present invention, high drainage soil that is not suitable for spraying is stored in a soil storage bag that is attached to the net body at a predetermined interval, so that high drainage suitable for drought-resistant plants is obtained.・ Create a highly breathable environment. Soil storage bags, which are located at regular intervals on the net body, support the sprayed soil and prevent slipping. Since the soil storage bag is formed by a net having a mesh size such that the mesh penetrates through the roots of the plant, the highly drained soil in the soil storage bag is not eroded by the water flow during rainfall. In addition, even if an accident occurs in which the sprayed soil is washed away, the highly draining soil in the soil storage bag remains without being washed away, and the plants spread out from there.

In the vegetation substrate according to the second aspect of the present invention, the three-dimensional lattice net provided between each of the soil storage bags arranged and fixed at regular intervals has the soil when applied to a vertical surface such as a steep slope or the wall of a building. Support and prevent falling. In the vegetation substrate of the invention of claim 3, the drainage band attached in a strip shape in the vertical direction of the back surface is
The necessary number is attached according to the inclination angle of the surface to be greened,
Effectively retains the appropriate amount of water and drains necessary for the growth of drought-tolerant plants. In the vegetation substrate according to the invention of claim 4, since the nets each have a net having a bottomless and bottomless three-dimensional shape, the soil is settled and flows into each three-dimensional object. Difficult to maintain the growth base necessary for plant growth.

In the greening system according to the fifth aspect of the present invention, a method of spraying a vegetation substrate containing a highly water-drainable soil, which is not suitable for spraying, in a soil storage bag of a net body is sprayed with a mixture of water-retaining soil and a breeding material. Allows spray construction using drought-resistant plants. The water-retentive soil is soft and does not damage the part or whole of the plant that has been mixed by mechanical spraying or the propagation material and machinery such as plant seedlings with soil. In combination with the highly draining soil in the soil storage bag, the drainage, breathability and water retention are well balanced, and plant growth is stabilized in a good condition.

In the greening system according to the sixth aspect of the present invention, the soil to be sprayed is changed from the water-retaining soil to the non-combustible soil so that the soil portion does not burn after the construction.

In the greening system of the seventh aspect of the present invention, drought-tolerant plants are used as a breeding material to be mixed with water-retaining soil or non-combustible soil. Many drought-tolerant plants are suitable for spraying because they have a high survival rate even if the leaves are broken during construction and the soil thickness is extremely thin. Also, by making the soil thickness extremely thin, it prevents the invasion of weeds and other plants in an environment where surrounding plants cannot grow. Therefore, it does not invade woody plants and destroy the growth base.

In the greening system according to the inventions of claims 8 and 9, a method of pushing in the soil portion of the plant seedling with soil and then pushing the soil to form a growth base, and a reliable survival rate can be obtained.

In the greening system of the tenth aspect of the present invention, by installing a root preventive sheet under the vegetation substrate, the growth of weeds originally growing on the surface to be greened can be prevented and weeds invading from the surroundings. It does not give the plant a place to infest because the soil on which its roots are lowered is under the root control sheet. It also prevents overgrowth of drought-tolerant plants.

In the greening system according to the invention of claim 11, by installing the water-blocking sheet under the vegetation substrate, the plant growth can be performed on a place where there is soil not suitable for plant growth such as strongly acidic or strongly alkaline soil. Create a place where possible.

In the greening method according to the invention of claim 12, by providing a water-impermeable and spreading layer on the surface to be greened, plant growth on a place where there is soil that is not suitable for plant growth such as strongly acidic or strongly alkaline soil. Create a place where possible.

1 is a perspective view showing an example of the form of a vegetation substrate I. As shown in FIG. The soil storage bag 2 attached to the net body 1 at regular intervals is formed of a net having a fine mesh such that the soil does not spill and the roots of plants penetrate. The soil storage bag 2 is filled with high drainage soil 3a. FIG. 2 shows a state in which the tubular bag 4 filled with the highly drainage soil 3 a is inserted into the soil storage bag 2. The tubular bag is made with the same fine net as the soil storage bag. The soil storage bag 2 is attached to the net body in stripes or in a grid pattern as required.

FIG. 6 shows a three-dimensional lattice net 9 in parallel with the soil storage bag in the center of the space formed between the soil storage bags 2 attached in such a manner that the net body 1 is laterally partitioned at regular intervals. It is a perspective view which shows the vegetation base | substrate I of the state which attached.
The vegetation substrate with a three-dimensional lattice net was developed for steep slopes. On steep slopes, soil runoff was severe due to the effects of wind and rain, and prevention of soil runoff was a major issue.
As a result of the experiment, the form in which the three-dimensional lattice net is provided between the soil storage bags as shown in FIG. 6 minimized soil runoff. As the three-dimensional lattice net, there is a three-dimensional lattice net made of plastic or the like, and the width thereof is 20 cm as a standard.

FIG. 7 is a perspective view showing an example of a state in which a strip-shaped drainage belt 10 is provided in the vertical direction of the back surface of the vegetation substrate I.
The figure shows the soil storage bag 2 and the three-dimensional lattice net 9 with the front side facing down in order to show the state of the drainage zone. As for the drainage zone, one or more drainage zones should be installed in the vertical center according to the construction environment, and the required number should be installed. When the vegetation substrate of the present invention was installed in 5 grades from a gentle slope to a steep slope, and water retention soil mixed with a propagation material was sprayed to a thickness of 3 cm to observe the drainage condition. When a drainage mat of the same size was installed in the same area, excessive drainage occurred at any slope, causing dry and fertilizer runoff, which caused water and fertilizer runout, resulting in poor plant growth. When the same experiment was carried out in the strip-shaped drainage zone shown in FIG. 7, the minimum water retention and drainage required for drought-tolerant plants with a low soil thickness were secured, and soil erosion was small and good growth was exhibited.
A 10 cm wide drainage zone was used in the experiment.

In experiments on vertical or steep slopes, a combination of a steep three-dimensional lattice net and a vegetation substrate having a required number of drainage zones in the longitudinal direction of the back surface gave good plant growth results. Also, in an experiment on a horizontal surface such as a rooftop with a water gradient, the vegetation substrate provided with a drainage zone in the vertical direction on the back side showed an appropriate state of water retention and drainage. Especially in places where the drainage condition is not good, the stagnation of water was solved by laying a drainage mat on the entire surface to be planted.

As the net body, usually, a single Russell net knitted in the vertical and horizontal directions or a three-dimensional net having a high soil fixing effect is used. The three-dimensional nets are made of extra fine net yarn, and the height of the stitches makes them one by one into a three-dimensional shape that is lined up in a bottomless shape. The double-raschel net or Hannie cam net, which is already in circulation as a three-dimensional net, has an object of retaining soil on the slope and has a stitch height of about 1 cm, but has a good soil fixing rate. According to the result of the experiment on a steep slope, when the height of the mesh of the net is increased from 2 cm to 3 cm, the amount of soil stored in the solid increases,
It was found that the settlement of the soil was improved. FIG. 3 is a diagram showing a three-dimensional net proposed by the present invention.

As the material for forming the net, chemical fiber type or natural fiber type can be appropriately selected and used. Also, non-woven fabric and the like can be used. Net body mesh is 4
The standard is 0 to 50 mm. The soil storage bag should have a hole through which the soil should not spill and the roots of plants should penetrate, and use a net with a small mesh.

The net body is usually formed continuously with a width of 150 cm. As the vegetation substrate I of the present invention, a length of 15 m is cut to a standard length and used. Soil storage bag 2
Is a cylinder with a diameter of about 3 cm and its length is 1 of the width of the net body.
50 cm. 25 cm to 50 cm on the net
Install at intervals. Depending on the type of plant and the place of construction, the intervals will be appropriate. The size of the vegetation substrate of the present invention is basically 150 cm wide × 15 m long × 3 cm thick (height of the soil storage bag and the three-dimensional lattice net).

The high drainage soil to be put in the soil storage bag and the tubular bag is a pumice stone such as mullet soil, volcanic gravel, perlite, husk chips of coconut, high denier fiber, zeolite, etc. with good drainage and air permeability. Soil or the like is used alone or in combination. Fertilizer, water retaining material, and fertilizer can be mixed if necessary. In addition, if necessary, use a soil bag and a tubular bag with nets that are large enough to prevent the soil from falling off. Depending on the situation, it is also possible to mix foliage, seeds, plant seedlings with cultivated soil, etc., which are not suitable breeding materials or those which can be sprayed.

When water retention is required to some extent depending on the construction site or the type of plant, the soil stored in the soil storage bag may be replaced with water-retaining soil instead of high drainage soil.

As the water-retaining soil used for spraying to form a growth base, and as the water-retaining soil in which a breeding material is mixed and sprayed, a soft peat moss having a water retaining capacity,
It is possible to select organic soil such as bark compost, peat, palm fiber, palm husk chips, low denier fiber, etc., which is a soil conditioner for palm. Furthermore, as another method for promoting the permanent growth of plants, microorganisms such as mycorrhizal fungi can be mixed. The soil becomes the home of microorganisms,
Creates a natural circulation and ecosystem with plants, and promotes sustainable growth.

Similar to water retentive soils, some non-combustible soils are suitable for mechanical spraying. Non-combustible soil that can be sprayed includes upland soil, volcanic ash-like soil such as burned black soil, and burned mountain sand. The use of non-combustible soil was developed for fire protection. What is especially noticeable these days is a fire caused by the throwing away of cigarettes on the slopes of the road. Spraying with non-combustible soil is recommended for places where damage is serious.

There is also a method in which a non-combustible soil is sprayed on a vegetation substrate to form a growth base in the same manner as the water-retaining soil, and then a plant seedling with cultivated soil is set as a breeding material. It also allows the use of non-combustible soil, which is not suitable for mechanical spraying.

By installing the water-blocking sheet on the entire surface to be replanted, the vegetation substrate and the revegetation system of the present invention can be used in a place where soil is originally unsuitable for plant growth. The water-blocking sheet shields the present invention from the surface to be greened, and shields soil in which plants cannot grow, such as strong acid soil or strong alkaline soil generated in road construction or landfill, and is affected by it. Do not let However, since the impermeable sheet is impermeable and no water is supplied from below, the impermeable sheet is extremely dry. Plants that can grow in an environment where a thin layer of soil is placed on a water-blocking sheet are limited to those that prefer dryness, such as drought-tolerant plants. The present invention has been developed on the premise of revegetation of artificial structures that are impermeable or close to impermeable, and on water-impermeable sheets that closely resemble the environment, vegetation substrates and revegetation of the present invention using plants that are drought-resistant plants The environment is suitable for the system.

In order to block the surface to be greened from the present invention,
As an alternative to installing a water-blocking sheet, there is also a method of providing a water-blocking layer on the surface to be greened. In order to prevent the influence of soil unsuitable for the growth of plants, as in the case of the water shield sheet, the surface of the present invention and the surface to be revegetated such as water movement are blocked. The tomaku layer is
It is provided by spraying asphalt, urethane, cement, etc. on the surface to be greened to form a film. The same effect as the water-blocking sheet can be obtained.

Since the water-blocking layer and the soaking layer can be easily provided by using a machine, the entire surface should be shielded, for example, when strongly acidic soil is generated over a wide area due to road construction or land preparation. Can be used effectively. A vegetation substrate is placed and fixed on the surface to be greened, and a water-repellent soil or a non-combustible soil mixed with breeding materials is used to vegetate it using a machine. The substrate is sprayed to form a greening system. Also, if necessary, a water-retaining soil or non-combustible soil is sprayed onto the vegetation substrate to form a growth base, and then plant seedlings with cultivated soil are manually pushed in to be installed to form a greening system. The land for construction is large and has many irregularities, and the greening system of the present invention, in which the base material used is sprayed soil or a flexible sheet, is flexible and can be fixed without difficulty according to the shape.

If necessary, a root preventive sheet is placed under the vegetation substrate. The root-control sheet prevents the growth of the weeds growing thereunder and prevents the invasion of surrounding weeds and weeds. If drought-tolerant plants are used on the surface to be revegetated, which is formed of soil while retaining water, prevent overgrowth. On the surface to be revegetated, which retains a lot of water, replacing the root preventive sheet with a drainage mat will improve drainage capacity, prevent weeds from entering and overgrown, and create an environment suitable for drought-tolerant plants.

To fix the vegetation substrate I on the surface G to be planted, an anchor 7 is usually used. For surfaces to be planted for disaster prevention, such as concrete slopes, use all anchors or straight anchors that do not penetrate to the bottom. In addition, anchors cannot be used on rooftops that have waterproof or root-proof layers, so fix them with fixing materials or adhesives.

FIG. 4 is a partially broken perspective view showing an example of construction of the greening system of the present invention. A water-blocking sheet 8 is laid on the greening target surface G which is a slope of acidic soil and the vegetation substrate I of the present invention is fixed by an anchor 7 thereon.
Furthermore, a state is shown in which the water-retaining soil 3b mixed with the propagation material is sprayed on it to a thickness of 3 cm using a machine. FIG. 5 is a sectional view thereof.

Depending on the situation, a water impervious sheet is laid or a layer for covering is provided. If necessary, a root protection sheet or a drainage mat is laid on the greening target surface G, and the vegetation substrate is fixed thereon.

When greening a place on the rooftop or the like where there is a waterproof layer on a surface that is nearly horizontal with only a water gradient, the vegetation substrate is fixed to the surface to be greened with a fixing material, and then water-retaining soil is sprayed. If the present invention is installed after fixing the protective sheet for protecting the waterproof layer, the risk of damaging the waterproof layer is further reduced. In places where the drainage condition is not good, a drainage mat will be laid on the entire surface to be replanted.

After installing the vegetation substrate of the present invention on the surface to be greened and spraying a water-retaining soil mixed with a reproductive material, or by spraying a water-retaining soil to form a growth base, the reproductive material can be optionally added. After pushing it to the position of
If necessary, cover the entire top with a net. If necessary, use a net with decoration. It is also possible to apply decorative colors.

The present invention is intended for greening places where it is difficult to plant green or places where much labor is required, such as the slopes that have been treated with concrete, the roofs and walls of artificial structures. Due to the large number, drought-tolerant plants suitable for the environment are the main plants used. The stems and leaves that are the whole plant or a part thereof, the stems and leaves that have rooted, and the cell-shaped seedlings with a small amount of soil as roots are used as the seedlings with soil. Seeds are available if necessary, although the initial growth is slow. Drought-tolerant plants that are viable even when torn are well tolerated even when mixed with soil and sprayed. In addition to spraying the breeding material by mixing it with the soil, the soil is first sprayed to create a growth base, which is then pushed into and installed. Alternatively, it is installed by mixing it with the soil packed in the soil storage bag or the tubular bag.

As the drought-tolerant plants, there are those typified by the genus Sedum of the Crassulaceae family, such as Mexican mannuncusa, Sakasamannengusa, Morimura mannengusa, coral carpet, and sprue, and those represented by the trunaceae family, such as cold-resistant matsubachi and minimatsubaku. Do not give more water than necessary, as excessive water can damage the roots and cause overgrowth. Drought-tolerant plants bloom in yellow, white, and pink, and if you combine them in consideration of color and season, you can enjoy designs and colors that change from season to season.

Even in places where there is no soil such as artificial structures, increasing the amount of soil expands the types of plants that can be used. However, since the types and amounts of invading plants also increase, the type and amount of soil can be adjusted according to the purpose. Change and use.

Plants other than drought-tolerant plants can also be used by adjusting the soil thickness that serves as a growth base, the drainage zone on the back surface of the vegetation substrate, and the like to the environment of the plant to be used. Breeding materials that cannot be sprayed, such as pot seedlings and bulbs, should be installed by pushing them into the sprayed soil or mixed in the high drainage soil in the soil storage bag. If the vegetation base and greening system are arranged in the environment of the plant to be used, the range of plant types will expand, and the range of construction sites will expand accordingly.

EFFECTS OF THE INVENTION According to the present invention, high drainage soil, which is not suitable for spraying by a machine, is stored in advance in a soil storage bag which is arranged and fixed at a predetermined interval in a net body, so that the soil does not need to be thick and management labor is not required. It became possible to perform mechanical spraying using drought-resistant plants. Since the vegetation substrate suitable for drought-tolerant plants and the growth base in the greening system are extremely dry, the invasion of other plants such as weeds was prevented, and the time and effort for maintenance such as irrigation and weed treatment were saved. In the conventional blasting construction of grass, 1
In the present invention, it is necessary to spray with a soil thickness of 0 cm or more, and the amount of soil used increases as the construction range expands, resulting in high cost. Costs have been reduced by reducing the consumption of materials. By installing and blocking the water impervious sheet between the surface to be replanted and the vegetation substrate of the present invention, it was possible to revere a place where there are strong acidic soils and strong alkaline soils where plant growth is not possible. We have realized a greening system using non-combustible soil that does not cause a fire.
