Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a slope cut out from a quarry site or road construction, a large-scale artificial structure such as a median strip of a highway or a roof of a sewage treatment plant, and a roof of a general house. Places where greening has been difficult so far, such as nearby artificial structures such as buildings and verandas, and waterfronts and parks such as rivers and lakes,
The present invention relates to a greening system and a greening method used for greening a garden, a flower bed, and the like, and a parting material used for the greening system and the greening method.

2. Description of the Related Art Greening of walls and rooftops of artificial structures such as concrete buildings and highways, which have been murdered, has attracted attention and has been implemented in recent years. Greening has also been attempted for places where concrete treatment is required for rock fall prevention and earth retaining, such as quarry sites in mountainous areas and slopes formed by land reclamation, for the same reason. In recent years, a method of greening by attaching to a surface to be greened has become common, and studies have been actively conducted on how to create a simple, simple, inexpensive, and high survival rate and high survival rate. However, in spite of much research and many proposals, the rate of utilization in actual construction is extremely low. The cause is probably that the survival rate of the plant that plays the leading role cannot be expected as much as expected, and the rate of stable growth for a long period of time even if the plant is activated is low. It is necessary to have a basic attitude to learn knowledge about the plants used from experiments and actual construction, and to make practical living knowledge. The present inventor has filed Japanese Patent Application No. 11-100.
455, Japanese Patent Application No. 11-374573, etc., and the 31st Annual Meeting of the Japan Society for Greening, "Study on efficient integration of mats and plant seedlings". We have used plants that are extremely resistant to drought, and have made proposals according to their properties and growth conditions. Among them, various problems such as survival rate, initial growth, simplification of construction work, reduction of maintenance work, protection from strong wind and heavy rain after construction, and water flow have been confirmed on site and solved one by one.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves problems such as poor drainage, misalignment of cultivation soil, scattering of cultivation soil, and peeling of a mat for greening, which cause plant death, and is effective for practical construction. It is an object of the present invention to provide a system and a method that enable simple enforcement even in a large-scale site together with permanent growth of a plant.

[0004]

In order to achieve the above object, the present invention uses, as one method, a drainage network having a fixing function comprising a plurality of drainage zones and a drainage zone fixing material. A drainage network is formed by crossing a drainage zone at an arbitrary point on the surface to be greened, and fixed with a special fixing material. The dedicated fixing material is used to stop a key portion of the drainage zone, cover the drainage zone from above, and fix a foot portion in contact with the surface to be planted with an adhesive or the like. As another method, there is a method in which a divided drainage network in which a drainage network is incorporated into an arbitrary size is arranged on a surface to be greened. Both methods use a bendable parting material without using a tool as a dedicated fixing material around the surface to be greened. At least the cultivated soil is accommodated in the grid formed by the drainage zone to form a growth base. The height of the cultivation soil can be easily filled evenly with the height of the top of the special fixing material or the height of the drainage zone, and the efficiency is good.
Install or disperse plant propagation material on the growth base. Unless it is not necessary, the growth base is solidified using a binder (the binder may be mixed in the soil in advance). Use the internet as needed.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention utilizes a drainage material efficiently. Since the drainage belts, which are strip-shaped drainage materials, are regularly arranged on the surface to be greened, there is no variation and the entire average amount of drainage is made. In particular, at the intersection where the drainage zones intersect, the water flowing from the vertical and horizontal directions merges and scatters vertically and horizontally, so that efficient drainage that stagnates can be performed. In addition, the drainage zone has a fixing function, and since the growth base is fixed to the surface to be greened as it is as a fixing material, the same level of force acts on the whole, so the fixing force is high. In addition, the drainage zone exists in the shape of a mesh in the soil, and acts as a framework in the soil to prevent the soil from shifting.

[0006] Materials for the drainage zone include non-woven fabric, porous concrete, styrofoam, plastic plate,
Bricks and the like. Any material having drainage capacity due to its material and its structure can be used.

FIG. 1 is a perspective view showing a state in which drainage zones are installed in a girder shape. After the drainage zone 1 is installed, the necessary parts are fixed with the drainage zone fixing material 2a and the drainage zone fixing material 2b as shown in the figure. When the installation location is strongly affected by wind and rain and the inclination is severe, the drainage zone is preferably temporarily stopped with an adhesive such as a liquid adhesive or a double-sided adhesive tape, and then the drainage zone is fixed with a drainage zone fixing material.

[0008] The interval between drainage zones is usually 100 cm on a substantially horizontal gentle slope such as a rooftop.
On the inclined surface, the ratio of the arrangement interval of the drainage zones and the vertical and horizontal intervals is changed depending on the inclination angle. For example, vertical 100c
The interval according to the situation is determined, for example, the m pitch width is set to 50 cm pitch or the like. If a flexible drainage zone made of a nonwoven fabric or the like is used, not only a flat surface but also a complicated shape can be handled.

[0009] The width and thickness of the drainage zone are varied depending on the thickness of the soil, the manner of installation, the environment in which the soil is installed and the like, which vary depending on the plant to be installed. Since the present invention does not limit plants,
Although a considerable amount of soil may be required, drought-tolerant plants, such as succulent plants that can grow on extremely small soils, are often used for greening artificial structures that are most in demand. When a succulent plant is used, a drainage zone having a width of 10 cm and a thickness of 2.5 cm is usually used.

[0010] The rhombus type shown in FIG. 2 and the parallelogram type shown in FIG. 3 are drainage zones 1 when installed in a place where the greening target surface G is an inclined surface.
It is a schematic diagram which shows the installation form of. It is a girder-shaped deformation designed to keep the cultivation soil that will be the growth base from slipping and to make the drainage smooth, and each is equipped with a drainage zone efficiently. FIG. 4 shows an oblique stripe shape obtained by simplifying the cross-girder shape. In the stripe type, the drainage zones 1 are installed in parallel at equal intervals, and are installed obliquely or horizontally as shown in the figure. In addition, any shape can be used as long as it can prevent displacement of the cultivation soil without opposing the flow of water.

When the surface to be revegetated is in a special environment, for example, in a place where puddles are so severe that a puddle can be formed or when a high gradient is required and a high drainage capacity is required, a drainage material is separately provided in the grid formed by the drainage zone. It is also possible to install the required amount. Separate drainage material may be the same material used for crushed perlite, pumice stone, stone, brick, etc., nonwoven fabric, water retention drainage plate or drainage zone, and there is no particular limitation as long as the required drainage capacity is obtained . Separately, drainage material will be laid all over the grid at an average height, and cultivation will be placed on top of it.

FIGS. 5 and 6 are perspective views showing the forms of the drainage band fixing member 2a and the drainage band fixing member 2b. FIG. 5 shows a form of a drainage band fixing member 2a for fixing a portion having a single drainage band. Depending on the plant used, the thickness of the soil to be introduced and the thickness of the drainage zone will vary, so the height of the drainage fixing material will be changed accordingly. Tests were performed using succulent plants that are frequently used to green artificial structures, and the following results were obtained. For succulent plants, width 10c
It is appropriate to use a drainage zone having a thickness of 2.5 cm and a thickness of 2.5 cm. The dimensions of the drainage band fixing material used for this construction are as follows: the width of the frontage of the drainage zone is 10 cm, which is the same as the width of the drainage zone, and the height of the frontage is 3.5 cm. Moreover, the dimensions were optimal for the drainage zone to be fixed without moving.
In addition, the length to cover the drainage zone is 10cm, and the width of the fixing feet extending to 7.5cm from the places that contact the greening target surface on both sides is 7.5cm each. As a result of the test, it was validated. In addition, if you fix it by inserting a bite into the gap created by the fixing material for the drainage zone over the drainage zone, or by fixing the non-slip material on the upper inside of the fixing material for the drainage zone, the fixing force will increase and there is a fixing function It was also found that it would strengthen the framework of the entire drainage network.

FIG. 6 shows a drainage band fixing member 2b used for a connecting portion where two drainage zones intersect and overlap each other. Since the drainage zone is a place where the drainage zone is assembled in a cross shape and straddles the connecting part, the drainage zone fixing material used for one piece shown in FIG. Both tops of the band fixing material are stretched and connected to the overlapping portion. Instead of the drainage band fixing material 2b shown in FIG. 6, the overlapping connecting portion of the drainage band is bound with stainless steel wire, and both ends of the connecting portion are sandwiched, and one end of the drainage band shown in FIG. There is also a simple method of fixing with the fixing material 2a. In particular, the present invention is effective when the overlapping of the drainage zones is not a cross shape which crosses at 90 degrees but a rhombus or a parallelogram. Drainage band fixing material enhances the fixing power of the drainage zone. Especially on sloping land, even if the drainage zone is stopped with an adhesive such as a liquid adhesive or a double-sided adhesive tape, it is often not possible to obtain a fixing force enough to prevent displacement of the cultivated soil by using only the adhesive force, so it is desirable to use the drainage zone together . The top of the drainage band fixing material serves as a base for fixing the upper net with screws. As the material of the fixing material, it is preferable to use a metal material that is not easily affected by ultraviolet deterioration.

FIG. 7 and FIG. 8 are perspective views of the parting material 3 used for fixing the periphery of the greening target surface. FIG.
Shows a general form of a parting material having a net fixed blade 5 at the upper end and a greening target surface fixed blade 6 at the lower end across the rising 4. In FIG. 8, the upper net fixed wing 5 is attached to a place one step lower, and the upper part is doubled and reinforced. The installation location is used, for example, on steep slopes, places exposed to strong wind and rain, and other places where strength is required. The fixed wing of the net has a small saw blade shape, and the fixed wing on the surface to be greened has a large saw blade shape, so it can be bent freely without using tools and can be easily used at right-angle corners and deformed corners. have. The height of the rise 4 is the same as the drainage band fixing material at the time of construction. Since the drainage zone and the growth base are sandwiched and fixed firmly to the shape of the crevice without destroying the overall balance such as the average thickness, there is no spilling or breaking of the soil. A drain hole 7 is provided on the lower side to discharge excess water for growing plants. The parting material is installed and fixed around the surface to be greened at the beginning of construction. After fixing the parting material, the drainage network is fixed to the surface to be greened, and soil is introduced. Around the corners, the height of the parting material is used as a guide so that the soil can be stored at an average height.

FIG. 9 is a cross-sectional view showing a state where the parting material 3 is installed. The double-sided adhesive tape 8 is stuck on the greening target surface G, which is the installation location, and is installed thereon. Since the greening target surface fixed wing 6 is jagged, the fixed area is small and the fixing force is weak. In order to compensate for this, it is preferable to fix the upper surface of the green fixing target surface fixing blade 6 again with the double-sided adhesive tape 8. In this case, the drainage zone 1 can be fixed using the upper side of the upper double-sided adhesive tape 8. Net 1 using net fixed wings 5
We put 0 and stop with washer 18 and screw 9. As the adhesive, a liquid adhesive can be used in addition to the double-sided adhesive tape.

As described above, the fixing material for the drainage zone and the parting material are usually fixed using an adhesive such as a double-sided adhesive tape or a liquid adhesive. If the adhesive such as double-sided adhesive tape or liquid adhesive cannot be used efficiently depending on the condition of the greening target surface, or if it is necessary to further increase the fixing force, switch to a fixing device such as an anchor or use a fixing device. Fix with an adhesive.

Next, a divided drainage network and a greening method using the same will be described. Rather than assembling the drainage network at the construction site, the divided drainage network is brought into an arbitrary size in advance and placed on the greening target surface. There are two types of split drainage networks, one with a mesh only and one with a bottom.

FIG. 10 is a perspective view showing an example of the divided drainage network 11 having only meshes. The area where the drainage zone intersects is fixed and has continuous grids. Basically, there are a plurality of squares, but there may be one in some cases. The figure assumes that the material of the drainage zone is a nonwoven fabric in order to show that the drainage zone can be folded and transported even if the interval between the drainage zones is large or the number of squares is large.

FIG. 11 is a perspective view showing an example of the drainage network 12 with a bottom surface. When the drainage network with a bottom is used, for example, in a place where the surface to be greened is rough, a growth base can be easily constructed and is convenient. The figure shows a case in which porous concrete is used as the material of the drainage zone, and is an example of a drainage zone formed of a non-foldable material. As shown in the figure, in the case of a drainage zone made of a non-foldable material, the drainage zone is narrowed, for example, to 50 cm, so as to be transportable. The bottom surface does not need to be the same material as the drainage network, for example, the bottom surface is also made of porous concrete as in the drainage network as shown in FIG. 11, and another material may be used. If you want to increase the drainage effect, select a material that matches it.

FIG. 12 is a cross-sectional view showing a method for arranging and fixing a required number of divided drainage networks with a bottom surface made of porous concrete shown in FIG. In the figure,
Assuming that the construction site is a greening surface having a waterproof layer, an example of a method of fixing the waterproof layer using an adhesive to prevent the waterproof layer from being damaged has been described. An inverted T-shaped split drainage fixture 14a is fixed at an arbitrary position on the greening target surface G using a double-sided adhesive tape 8 (or an adhesive such as a liquid adhesive). Next, sandwich the upright bolt of the split drainage fixture 14a,
As shown in the figure, the divided drainage networks 12 with bottoms are arranged side by side, and a washer 13 dedicated to the divided drainage network is passed through an upright bolt of the fixing device 14a for the divided drainage network, and installed so as to straddle both of the divided drainage networks. The nut 24 is fastened to the bolt of the split drainage fixture 14a protruding from the dedicated washer 13. The same operation is performed in a place where the divided drainage fixture 14a is arbitrarily arranged, and the entire bottomed drainage net 12
Is fixed to G on the surface to be greened. FIG. 13 is a cross-sectional view showing a method of arranging and fixing to the greening target surface G when the material of the divided drainage network with bottom surface 12 is a nonwoven fabric. At the joint where the bottom divided drainage network 12 is arranged, the upper end of the divided drainage network fixture 14b is connected to one bottom divided drainage network 1 as shown in the figure.
It is placed over an arbitrary position on the outer frame of No. 2 so that the gap between the joints can be passed through, and the lower end of the other divided drainage network with bottom surface 12 can be put under the outer frame. The washer 13 dedicated to the divided drainage network is installed over both of the divided drainage networks so as to cover over the divided drainage network fixture 14b. One point of the washer 13 dedicated to the divided drainage network and the fixing device 14 of the divided drainage network are cut out and fixed to the divided drainage network located thereunder with screws 9.

A cultivation soil is accommodated in at least a grid formed by a drainage network in which a plurality of drainage zones are fixed at a plurality of arbitrary locations to form a growth base. When a drought-tolerant plant represented by a succulent plant is used as a plant, a high drainage power is required, and therefore, a recreation-like soil such as ceramic, pumice, or crushed brick is used alone or as bark, peat moss, mulch It is advisable to use it by mixing it with one or more organic soils. Depending on the type of drought-tolerant plant, crushed ceramic, pumice or brick, which is a reticulate material, can be used alone. In order to obtain the high drainage capacity required by drought-resistant plants, pumice is separately spread to a height of 2.5 cm as drainage material, and peat moss, bark, charcoal, mulch, pumice, fertilizer, etc. are mixed as cultivation on it 1cm
The results showed that the growth substrate spread at the height of the succulent plant was effective in the test using succulent plants.

As a method of introducing the soil, there are a method of burying the drainage zone and a method of exposing the drainage zone. The advantage gained by burying the drainage zone in the soil is to prevent the drainage zone from being deteriorated by ultraviolet rays. In addition, when the drainage zone enters the soil, different soil thickness portions are generated, which prevents the entire surface from being killed by humidification caused by abnormal weather or the like. The advantage obtained by storing the cultivated soil only in the squares and exposing the drainage zone is that air is easily taken into the cultivated soil, which is effective for plant growth. It also has a high effect of preventing the soil from flowing out. Whether or not the drainage zone is buried depends on the conditions at the construction site, the types of plants used, and the material of the drainage zone.

In the present invention, the use of small seedlings with cultivated soil as a propagation material for plants is the standard. A small seedling with cultivation soil is set aside. Simply scatter small seedlings with cultivated soil on the growth base and they will be in a lying state. Although it may be used as it is, it is effective for growth to spread the root part with cultivation into the growth base after spraying to obtain a higher survival rate. There is also a method of planting small seedlings with cultivated soil on a growth base in a standing state. It takes time but has a good growth rate. Cultivation thickness 2
It is easy to plant something as thin as about cm on a thin growth base. The seedlings may be planted in a standing state. Generally, pots having a diameter of 9 cm, which are widely distributed, are easily available. Normally, it has a depth of 7 cm, but it is easy to use if it is 4 cm deep and a thin 9 cm pot seedling is used.

FIG. 14 shows a seedling using a nursery box newly proposed as a plant propagation material in the present invention. The seedlings 25 are cultivated in a seedling box 26 of an arbitrary size, and the plants that have grown sufficiently are taken out of the seedling box together with the seedling box or taken out of the seedling box to the construction site. Is the way. Growing is good because the rooted roots, which are generated when the growing period is too long, are loosened by being torn off. As a dividing method, a tool such as scissors may be used instead of the tearing. 45cm in height in the present invention
A seedling box having a width of 45 cm and a height of 3 cm and containing cultivation soil in a thickness of 2 cm was used. In the case of large-scale construction, there is an advantage that the tomato seedlings can be divided freely into the required size of seedlings, so that they can be used flexibly and flexibly, and that they can be produced at 1/3 the cost of using pots. In particular, a significant cost reduction becomes possible. Since the seedlings have grown sufficiently, the growth rate after construction is good. As shown in the present invention, a combination of a seedling seedling and a binder is effective for greening a place where greening is difficult such as an artificial structure, such as installing on a growth base of a soil containing a binder or hardening with a binder after installation. .
The drainage material is not limited to the drainage network according to the present invention, but can be used in various ways, such as combining with other drainage materials. Plants that can be used for towing seedlings include Mexican stonecrop, Japanese turf, and moss.

As a plant propagation material, seeds and foliage of succulent plants can be used. Seeds and foliage show strong viability when rooted, but have the disadvantage that the lack of greenery persists because the survival rate is low and the period until volume is long. A high growth rate can be expected when used in combination with small seedlings, pot seedlings, and tomato seedlings having the above-mentioned soil.

In addition to the method described above, the present inventor disclosed in Japanese Patent Application
Attach a plant that is grown on a net or mat and covers it to some extent, as proposed in the net system for thinning greening of 1-158486, the mat system for thinning greening of Japanese Patent Application No. 11-374573, and the like. There is also a method. If a material with a high covering is used, the covering rate will be higher than at the beginning of construction.

[0027] Depending on the location conditions, not only on the inclined surface but also on the roof, depending on the location conditions, the flying of the soil and the deviation of the soil may occur. There are a method of using the binder to spray and harden the surface, and a method of mixing the binder in the soil in advance. To harden the surface, spray over the soil. When the binder is sprayed at a rate of 3 l / m ² , about 1 cm of the surface is hardened, although it depends on the type of the binder and the type of the soil. In the present invention, the standard method is to spread a binder and harden the surface after the propagation material of the plant is placed on the growth base. In experiments using vinyl acetate or acrylic acid ester as a binder, almost no effect on the plant due to the binder was found, but depending on the type of plant or the type of binder, etc., after spreading the binder, the propagation material of the plant was installed. Sometimes. However, it is not always necessary to use a binder if there is no need to worry about leaching or displacement of the soil due to the location conditions of the construction site

When mixing in advance, the binder is mixed with the soil and stirred. The soil with binder is often in paste form. A plant propagation material is placed on a growth base formed by containing a binder-containing soil in at least the squares of the drainage network formed on the surface to be greened. It is effective to use paste-filled soil containing binders on steep slopes. There is also a method in which a propagation material of a plant is mixed with a cultivated soil containing a binder which is in a paste form and installed.

In an environment such as a steeply inclined surface or a horizontal surface exposed to heavy wind and rain, a net is used in addition to the binder. The net also serves as a hold down for the plants and provides higher strength. Immediately after construction, the net is too conspicuous because the seedlings have a small amount of greenery. If the net is to be avoided, embed the net in the soil for cultivation. Or consider the color of the net.

The net is fixed with a fixing member using the net fixing wing of the parting material, the top of the fixing member for the drainage band, or another fixing device or one point on the upper surface of the drainage band as a locking point. FIG.
In order to suppress flapping of the net 10 and achieve good growth of the plant, a net fixing device 15 is additionally provided if necessary in addition to the above. The net fixing member 15 is smaller in width than the drainage band fixing member 2a or larger than the mesh size of the net to be covered with the same. The washer is put on the net and fixed to the net fixture 15 with the screw 9. In drainage, it is particularly necessary when the interval between drainage zones is wide and the area of the cells is large. The drainage band fixing member 2a may be used as a net fixing device.

In the present invention, a method of placing a plant propagation material on a growth base and holding it down with a net is a standard. In the case of using a net, it is more efficient to spray the binder to be used after the net is installed.

There is also a method in which after the net is set on the growth base, the propagation material of the plant is planted between the stitches. Since the leaves are exposed on the net from the beginning, there is an advantage that the net is inconspicuous.

In addition to the binder and the net, the use of a three-dimensional lattice network (filament) is effective for preventing wind bleeding and runoff of the soil. By incorporating a three-dimensional net into the cultivation soil, the effect of preventing erosion of the cultivation soil is high, and a high fixing force can be obtained.

When the surface to be greened is a waterproof layer, a protective sheet for the surface to be greened is installed for protection thereof, to prevent the roots of plants from entering, and not to damage the waterproof layer during construction. There are also ways to install the present invention.

It is also possible to use a water-permeable protective sheet, install a drainage network having a fixing function, and then install it over the drainage network. If a water-permeable protective sheet that has both water permeability and water drainage is used, a better drainage power can be obtained in combination with a drainage zone. The water-permeable protective sheet can protect the waterproof layer, but may be used in combination with the greening target surface protective sheet if necessary.

FIG. 16 shows an example of the present invention on a greening target surface assuming a rooftop. Drainage zone 1 is installed in a girder shape,
It is a partially broken perspective view showing a structure of the present invention in which greening is performed using a drainage network having a fixing function of being fixed to a surface G to be greened with a drainage band fixing material 2a and a drainage band fixing material 2b. A protective sheet 16 is laid on the surface G to be greened, and a drainage zone 1 is placed thereon.
And a drainage network having a fixing function, which is a combination of the drainage band fixing material 2a and the drainage band fixing material 2b, is installed in a grid pattern.
The parting material 3 is used around the corner. The cultivation soil 17 is introduced into the drainage grid formed by the plurality of drainage zones to form a growth base. (In this figure, the drainage zone is buried in order to prevent ultraviolet deterioration, taking into account the fact that a polyester nonwoven fabric is used as the drainage zone). A small seedling 13 with cultivated soil is laid down on the growth base. The whole is covered with a net 10 and the net 10 is fixed with a washer 18 and a screw 9 to a locking point of the top of the drainage band fixing material 2 a and the drainage band fixing material 2 b and a locking point of the parting material 3. Finally, a binder is sprinkled to form a cultivated soil 20 solidified with a binder having a thickness of about 1 cm. In the figure, the net portion and the binder applied on the plant are omitted in order to show the situation of solidifying the surface of the target soil.

FIG. 17 is a cross-sectional view of the present invention of FIG. The non-slip 22 is fixed to the upper inside of the drainage band fixing tool 2a, and the drainage zone penetrating therethrough is fixed by the jagged blade of the non-slipper, thereby more strongly fixing the drainage zone. Instead of slip prevention, a gap may be filled.

The drainage network proposed by the present inventor in Japanese Patent Application No. 11-158486, which can perform substantially the same function as a drainage network having a fixing function composed of a drainage zone and a drainage zone fixing material, is disclosed. is there. The drainage pipe is fixed to the surface to be greened by an adhesive layer provided on the bottom surface, and the entirety is fixed using a locking point at the top or middle part of the drainage pipe. Except for the bottom of the drainpipe, there are small holes for ventilation drainage. Water is discharged from the growth base in the area separated by the drainpipe, collected in a small hole in the drainpipe, and discharged to the outside. Further, Japanese Patent Application No. 10-265633 proposes a method in which a simple drainage pipe is installed under a greening mat with a double-sided adhesive tape and is directly attached to a greening target surface. The drain pipe is made of a material that can be drained and is not crushed by pressure. Similarly, a hollow pipe that is strong in pressure and has a myriad of fine holes is used. By attaching this drainage pipe to the surface to be greened with double-sided adhesive tape, it can be used in almost the same manner as the drainage network with a fixing function of the present invention.

By applying the drainage network of the present invention, the following use is also possible on steep slopes. In order to prevent spillage of the cultivated soil that may occur when the divided drainage network is placed on a steep slope, cover the bottom of the square to about 2/3. In order to secure an inlet for cultivation soil, remove the drainage zone on the upper side when installed. FIG. 18 shows a drainage network for steep slopes, which is an application of the present invention made of porous concrete. Drainage zone 1
FIG. 10 is a perspective view of a state in which a divided drainage network 21 for a steep slope is vertically set with a square having one side removed and a lid closed to 2/3. Put the cultivation soil 17 from the top with the drainage zone removed, and a small seedling (or other plant propagation material) with cultivation 19
Is installed. In order to fix the divided drainage network for steep slopes to the surface to be greened, fix the drainage network for four steep slopes with a washer and an anchor at the corner where the corners meet. At each corner, the washers hold the four drainage networks for steep terrain, and the anchor can penetrate to the greening target surface.

Further, the drainage zone used in the present invention can be used for greening a folded roof which is currently widely used as a factory roof. The folded roof is made of iron and has a shape in which uneven waves are parallel. Drainage zones are laid all over the bottom of each dent, and fixed with drainage fixing materials for folded roofs. The fixing material for the drainage band for the folded roof is a metal plate with a series of irregularities of about 10 cm in width in the shape of the unevenness seen from the front of the folded roof, and after installing the drainage band at the bottom of the roof, Cover from above and fix. Fix at regular intervals. On the drainage zone, cultivation material is introduced at an average height lower than the convex top of the folded roof to form a growth base, and plant propagation materials such as small seedlings with cultivation are installed. The net is fixed with the convex top of the folded roof as the locking point. Finally, a binder is sprayed on the whole to harden the surface.

For the purpose of greening artificial structures such as concrete and quarry sites, which are the places where greening is difficult, which is the main feature of the present invention, succulent plants with a high dry-resistance, such as Sedum, are suitable. Cranberry and Mexican stonecrop. Excessive irrigation can damage the roots and cause breeding, so on the contrary it is appropriate to keep the water content as low as rainwater and leave it in a natural state. Depending on how the plants are combined, yellow, white, pink and blossoms can be bloomed, and green can be kept all year round. You can enjoy designs and colors that change every season.

Succulent plants are required to have a particularly efficient drainage power, and in addition to the minimum water retention required for permanent growth (not particularly required where rainwater is available). Since the base material suitable for succulent plants has an extremely high degree of dryness, it prevents invasion of other plants such as weeds, and saves time and labor for watering and weed treatment.

The vine is a plant that can cover a wide area in a short amount in a small amount. We use according to the situation of the spot to use.

The effect of the finely divided area of the drainage network having a fixed function in which a plurality of drainage zones are crossed in a girder shape or a diamond shape is as follows. 1. Since the entire drainage zone, which is the mesh of the drainage network, is fixed to the greening target surface, the fixing is reliable. 2. There is no displacement, runoff, or scattering of the soil. 3. Drainage power is certain. 4. Even if the soil is hardened with a binder, if the area is large, the whole is easily broken. By finely dividing the area and reducing the area, the effect of the binder is also enhanced. 1, 2, 3, and 4 are basic items that are indispensable for healthy plant growth.
