First, the installation structure of the slope greening frame of the present embodiment will be described in detail. As shown in FIG. 1 to FIG. 6, the installation structure of the slope greening frame according to the present embodiment is a slope greening method in which a scent 1 formed by bundling and bundling a plurality of branches 1 a is formed in a lattice shape. A frame 3 is installed and fixed with the scab 1 arranged obliquely on the slope 4.

As shown in FIG. 1, the coarse lobe 1 is formed by bundling a plurality of branches 1a having a diameter of 3 cm or less cut by lower pruning into a length of about 2 meters and a diameter of about 20 cm. It was also formed. Such coarse robe 1 has a coarse eye and does not have to worry about clogging even if litter or dust accumulates.
Water flows through the scent 1 and rainwater and snowmelt in the slope greening frame 3 can be drained well. It is preferable to use a branch that is easily rooted, such as a willow branch, for example. If the scent 1 is formed by willow branches,
The slope 1 itself takes root, and the slope 4 is greened by a willow tree.

The scent 1 is used for the purpose of drainage as described above. However, since the tree branches 1a are used, it is possible to retain an appropriate amount of water. Furthermore, the above-mentioned scent 1
Is formed by bundling a plurality of branches 1a, so that even if the roots of the trees planted in the slope greening frame 3 enter the coarse lobe 1, the branches 1a are bent. The function of the scent 1 is not impaired. For this reason, the root of the tree penetrates through the scent 1 and penetrates into the adjacent slope greening frame 3 so that the root stretches and the slope 4 is stabilized.

As shown in FIGS. 4 to 6, the slope greening frame 3 is formed by assembling the rough lobes 1 in a lattice shape, placing the loose lobes 1 obliquely on the slope 4 and installing and fixing them. You. In order to form such a slope greening frame 3, the scent 1 is horizontally arranged on the slope and the shoulder, and the scent 1 is obliquely arranged on the slope 4 to form a lattice.

A connecting member 5 having a cross shape as shown in FIG. 2A is provided on the upper and lower portions of the connecting portion of the scent 1 arranged on the slope 4 so as to firmly fix the connecting portion. Then, an anchor pin 8 shown in FIG. 3A is driven into the scent 1 through a hole 10 formed in the connecting member 5.

FIG. 2 (b) shows a connecting portion between the scent 1 arranged on the slope 4 and the scent 1 arranged on the butt and shoulder.
3 is attached, and an anchor pin 8 shown in FIG. 3A is driven into the loose lobe 1 through a hole 11 formed in the connecting member 6. Such a connecting member 6
Is set on the slope 4 before placing the scent 1 on the slope 4. In this manner, if the connecting member 6 is set under the loose lobe 1, it is possible to prevent the outflow of the soil 13 described later.

Further, the scab 1 arranged on the butt and the shoulder
2C has an arc-shaped connecting member 7 shown in FIG.
Then, an anchor pin 8 shown in FIG. 3A is driven into the scent 1 through a hole 12 formed in the connecting member 7.

Then, as shown in FIG. 3 (b), anchor pins 9 each formed by welding a semicircular iron plate 9b to the upper part of a reinforcing bar 9a are driven into each of the stubble 1 to put the stubble 1 on the slope 4
Fixed to. Since the upper portion of the anchor pin 9 is formed in a semicircular shape in accordance with the cylindrical shape of the rough lobe 1, the rough lobe 1 can be firmly fixed to the slope 4.

The connecting members 5, 6, 7 and the anchor pins 8, 9 are all made of iron, and hold the stable slope greening frame 3 until the tree grows, and the tree grows. It will rot in 5 to 10 years and return to soil. If the slope 4 is soft soil such as sandy ground, the connecting members 5, 6, 7 and the anchor pins 8, 9 may be formed of bamboo.

When assembling the slope greening frame 3, since the connecting members 5, 6, 7 suitable for each purpose are used, the exact position of the scab 1 can be easily grasped. Thus, the joint of the scent 1 can be firmly fixed.
Also, since the anchor pins 8 and 9 are driven into the stubble 1 to fix the stubble 1 to the slope 4, even if a load due to rainwater, snowmelt, fallen leaves, etc. is applied to the stubble 1, the slope greening frame 3 does not shift and break.

Further, the slope greening frame 3 assembled as described above is firmly and stably installed and fixed regardless of whether the slope 4 is a gentle slope or a steep slope. Normally, if the slope angle θ of the slope 4 is 30 degrees or more, rainwater or snow-melting water causes the soil to flow out, trees do not grow, and slope greening cannot be achieved. However, in the case of the above-described slope greening frame 3, a stable slope 4 can be obtained even if the slope angle θ of the slope 4 is as steep as 30 to 60 degrees.

Next, a slope greening method using the slope greening frame 3 assembled as described above will be described. First,
As shown in FIGS. 7 and 8, the soil 3 is filled in the slope greening frame 3. The soil 13 comprises a mixture of 100 parts by volume of purified water cake generated during the process of making drinking water, 20 to 60 parts by volume of coconut fiber or peat moss for improving water retention, and 5 to 15 parts by volume of bark compost. In the present embodiment, a soil made by mixing 80 parts by volume of purified water cake and 10 parts by volume of coconut fiber (Sumirin Agricultural Industry Co., Ltd.)
(Trade name: Tokyo Dotaro).

Then, a synthetic resin powder is mixed with the soil 13 as an erosion inhibitor. The synthetic resin powder is mixed at the time of packing the soil 13 into a bag, and is uniformly stirred in order to eliminate a variation in quality. Examples of the synthetic resin powder include vinyl acetate veova copolymer resin, modified vinyl acetate resin, vinyl acetate ethylene copolymer resin, special copolymer resin,
An acrylic copolymer resin, a vinyl acetate acrylic copolymer resin and the like can be mentioned. The synthetic resin powder preferably has a weight of 1 to ³ kg / m ³ .

As described above, by using the purified water cake generated in the process of producing drinking water on the soil 13, the water permeability, water retention, and air permeability are good, and N, P, and K are contained. Rich in trace elements, trees grow quickly, and slope 4 can be stabilized early. Further, since the synthetic resin powder is mixed in the soil 13, the ground of the slope 4 and the soil 13, that is, the soil particles are adhered to each other, and the soil 13 flows out and the load on the slope greening frame 3. Can be suppressed.

In order to fill the above-mentioned soil 13 into the above-mentioned slope greening frame 3, it is necessary to use a high-rise spraying machine or a pumping machine to stir the purified water cake, coconut fiber and synthetic resin powder so as not to be biased. Spray 13 The filling amount of the soil 13 is preferably a minimum soil thickness of 15 cm or more in order to plant the pot seedlings 14.

Next, as shown in FIG. 9 to FIG. 11, pot seedlings 14 of trees are planted in the slope greening frame 3 filled with the soil 13. That is, the seedlings of the tree cultivated in the vinyl pot are removed from the vinyl pot, and are planted in the planting holes of the soil 13. The pot seedling 14 has a height of 0.
And 3 to 0.8 m, 1 m ² per 1pot~4p
Plant trees as ot.

For trees, select plants suitable for the local vegetation. The criteria for selection are compensated vegetation (vegetation that has survived in proportion to certain anthropogenic factors) and potential natural vegetation (what natural vegetation will return to when anthropogenic factors disappear, and have potential capabilities). Vegetation of the theory) and natural vegetation (vegetation that grows naturally without any human influence). However, in order to plant on steep slopes, deep root type and intermediate type root trees are mainly selected, but it is necessary to plant a little (up to 30% of the whole) in the sense that the shallow root type covers the soil surface. In addition, on steep slopes (inclination angles of 45 to 60 degrees), drooping root-type trees such as pine are added in consideration of erosion prevention. Vegetation distribution consists of a forest edge (sode community) that is hardly hindered by growth such as wind, sunshine, and drying, a cloak community to protect seedlings, and a forest vegetation that forms a canopy of high tree layers. .

For example, in the vicinity of Matsukurayama, Haga-gun, Tochigi Prefecture, compensation vegetation is a mulberry-Konara community and potential natural vegetation is a shirakashi community. As shown in FIG. 9 to FIG. 11, as the mulberry- Quercus assemblages, the sapling (deep), kunugi (deep), chestnut (deep),
Yamazakura (medium), Egonoki (shallow), Japanese hornbeam (shallow),
Red hornshade (shallow), shirakashi (middle), viburnum (middle) for the cloak community as shrub 15, murasakisikibu (shallow), kamatsuka (shallow), and mosquitoes, yabukouji, yaburan etc. for the sod community as the undergrowth 16.

As the shirakashi assemblage, shirakashi (medium), vladinki (middle), yabutsubaki (shallow), shirodamo (middle), yab nikkei (middle), and shrub 15 Deep), aoki (shallow), rat mochi (shallow), chanoki (deep), nanten (medium), japonica (middle), hanaikada (shallow), viburnum (middle), benetida, takeokazu, Yabu Koji and the like are preferred. Note that (deep) indicates a deep root type, (middle) indicates an intermediate type, and (shallow) indicates a shallow root type.

Next, the surface of the above-mentioned slope 4 is mulched with white clover seeds, tree bark chips, straw, etc. to prevent erosion, control weeds, stabilize the soil temperature, and suppress moisture evaporation of the soil. At this time, an aqueous synthetic resin emulsion (for example, an acrylic copolymer resin, a vinyl acetate resin, or a vinyl acetate ethylene copolymer resin) is mixed with the above white clover seeds so that these are not scattered by the wind or run off by rainwater, and the soil 13 Spray.

The tree bark chips have a thickness of 30 mm or more.
An acrylic resin such as an acrylic resin, an acrylic styrene copolymer resin, or an acrylic copolymer resin is diluted with water in an amount of 200 g to 600 g per 1 m ² and sprayed on the surface. Straw is spread evenly over 3 kg to 6 kg per 1 m ² on the soil 13, and the straw is fastened using a straw rope or a straw rope. Rope spacing is 40cm ~
The length of the wire is set to 50 cm, and the length of the wire, which is 50 cm to 60 cm, is folded in half. Both ends of the rope are made of wood or bamboo skewers with a diameter of about 5 cm.

By mulching the surface of the slope 4 by any method, the stability of the slope 4 in the initial stage (about 3 years) is achieved, and after 3 years, most of the ground surface is covered with trees.
Since the amount of green is secured, the occurrence of weeds is suppressed.

As shown in FIGS. 9 to 11, shrubs 15 and undergrowth 16 of the above-described type are planted near the slope of the slope 4 as shown in FIGS.

A tube (cylinder or prism) of 50 cm to 200 cm in length made of polypropylene, paper or plastic is used for preventing deer and rabbits from feeding damage, reducing weeding work, and promoting tree growth by the greenhouse effect in the tube.
Cover the planted tree with wooden or iron posts to prevent falling. In addition, the tube has a circumference of 5 mm to 1 mm.
The 0mm of the hole from 10cm ² to 30cm ² may be working to prevent stuffiness by opening one place.

When the pot seedlings 14 are planted in the slope greening frame 3 as described above, the height of the tree 17 becomes 1-2 meters after 2-3 years, as shown in FIG. . Five years later, as shown in FIG. 13, the tree 17 grows to a height of 3 to 5 meters.

As described above, according to the present invention, it is possible to prevent the outflow of the soil and to sweep water, to achieve greening of the slope by trees, and to stably slope the slope even at a steep slope of 30 ° or more. Can be provided. In addition, the use of the natural material of the scent causes the trees to grow and the soil layer to stabilize and then corrode, returning the scent to the soil. Thus, according to the present invention,
Unlike the chemical substances, the savages use natural recycled materials, so there is no risk that harmful substances will dissolve into the soil. The soil of the present invention is not only suitable for growing trees to be planted on slopes, but also suitable for planting street trees and the like.

As described above, specific embodiments to which the present invention is applied have been described. However, the present invention is not limited to the above-described embodiments, and various changes can be made. For example, in the above-described embodiment, the stubble 1 is arranged obliquely on the slope 4 and is framed in a rhombus shape. However, the stubble 1 is arranged vertically and parallel to the slope 4 to frame it in a girder shape. You may do it.

Also, in the above-described embodiment, the 3 shown in FIG.
Although the connecting portions of the scent 1 were connected using all types of connecting members 5, 6, and 7, even if all of them were not used, at least the quadruple-shaped connecting member 6 shown in FIG. If linked, a framework can be formed.
