As shown in FIG. 3, a column member 8 is erected on the lower horizontally long member 4 by welding or the like, and is supported at or near the head of the column member 8. As the column member 8, the same material as the lower horizontal elongated member 4 and the upper horizontal elongated member 5 is used. Examples of the support means include welding, binding with a wire material or the like, bolt fixing, a combination thereof, and the like.

As shown in FIG. 4, a legal frame 9 formed by spraying concrete or the like is constructed around the net body 3, and the legal frame 9 supports both ends of the upper horizontally long material 5. Examples of the supporting means include embedding in the legal frame 9, bolt fixing, anchor driving, a combination thereof, and the like.

The upper vertically long material 10 is fixed above and below the slope 1 by anchors or the like (not shown). The upper vertically long material 10 is similar to the upper horizontally long material 5 as long as it can maintain its shape and strength until the point where the soil is put in and the staircase shape of the net 3 is held by the presence of the soil. Good. Therefore, as the material of the upper vertically long material 10, other than the same material as the lower horizontally long material 4, a material which corrodes over time can be used. Alternatively, a material that does not corrode may be used and removed after the construction is completed.

As shown in FIG. 6, a legal frame 9 is constructed around the mesh body 3, and an upper vertically long material 10 is vertically extended from the upper side frame 9A to the lower side frame 9B of the legal frame 9. It is fixed and supported so as to be suspended from the upper vertically long material 10. Examples of the support means include welding, binding or suspension with a wire material, bolt fixing, a combination thereof, and the like.

Is the same as above.

As shown in FIG. 7, at least one vertically arranged lower vertically long material 11 is fixed to the lower horizontally elongated material 4 in an intersecting state. And is supported at or near the head of the column member 12. Examples of the support means include welding, binding with a wire material or the like, bolt fixing, a combination thereof, and the like.

When the upper longitudinal member 10 is provided as shown in FIG. 3 and the grooved steel or the angle steel is used as the upper longitudinal member 10, the upper longitudinal member 10 is used as a work scaffolding trolley or material. It can also be used as a guide rail for transport vehicles.

In the case where the above-mentioned support means is employed, and such support is adopted in advance at a factory or the like instead of at a construction site, as shown in FIG. The net structure according to the third aspect of the present invention (claim 3), which forms a waveform in which a staircase shape is obtained at the stage, is formed. Therefore, since the dimensions and the number of steps corresponding to the slope 1 to be applied as the net structure can be manufactured in advance in a factory or the like, the on-site work can be significantly reduced.
It is possible to improve workability, shorten the construction period, and reduce costs.

Further, when supporting means is employed, and when such supporting is employed in advance in a factory or the like instead of at the construction site, as shown in FIG. Thus, a net structure according to the third aspect of the present invention (claim 3), which already has a complete step shape, is formed. Therefore, since the dimensions and the number of steps corresponding to the slope 1 to be applied as the net structure can be manufactured in advance in a factory or the like, the on-site work can be significantly reduced, and the workability can be improved. The construction period can be shortened and the cost can be reduced.

In the case where the supporting means and are employed, as shown in FIG. 10, the net body 3 merely forms a sheet before being arranged on the slope 1,
The work at the site can be reduced by laying the lower horizontally long material 4 (and the upper horizontally long material 5) on the net 3 in advance at a factory or the like instead of at the construction site. When carrying in to a construction site, the net 3 can be rolled and transported with the lower horizontally long material 4 (and the upper horizontally long material 5) as a core.

Next, examples of the soil retaining sheet 6 include a fibrous net-like sheet or a sheet made by welding a heat insulating sheet made of a fine wire mesh, or a water-permeable sheet such as a fibrous nonwoven fabric. Those that stop are preferred. By using a water-permeable material as the soil retaining sheet 6, surplus water can be drained even when the soil containing moisture is charged.
The earth retaining sheet 6 is fixed to the net body 3 and / or the lower laterally long material 4 and the upper laterally long material 5 with a wire such as a string or a wire, an industrial stapler, or the like, or adhered with an adhesive. I do. When the lower end of the earth retaining sheet 6 is bent upward along the slope of the slope 1 as shown in FIG. 8, it is possible to prevent the outflow of the soil along the slope of the slope 1. It is preferred.

Also, as shown in FIG. 9, attaching a sheet-like or plate-like heat insulating material 13 in addition to the earth retaining sheet 6 improves the weather resistance when applied to a region where the temperature changes greatly. It is suitable. Examples of the heat insulating material 13 include a sheet made of a resin such as polypropylene, polystyrene, and polyethylene or a recycled resin, and a foamed or foamed resin plate. Further, the use of a water-permeable heat insulating material is more preferable because cooling by vaporization heat can prevent an unnecessary rise in temperature even when the temperature rises, and can prevent high-temperature damage and drying damage.

Next, the method of constructing the slope greening structure (see FIG. 1) having the above structure, that is, the present invention 4 (claims 4 and 5,
9, 10 and 11), the present invention 6 (claims 6, 7, 9, 1)
0 and 11), the present invention 8 (claims 8, 9, 10 and 1)
The slope revegetation method 1) will be described.

First, the present invention 4 will be described. FIG.
Are stretched from the shoulder of the slope 1 to the bottom of the slope in a wavy form. In addition, the lower horizontal long material 4
May be already installed in a factory or the like as shown in FIG. 10, but is laid horizontally on each wave bottom portion T of the waveform of the net body 3 in a slope width direction at the construction site, and And the wave bottom T of the net 3 may be fixed. After stretching, the lower horizontal elongated member 4 is fixed to the slope 1 with at least two anchoring members 14 such as anchors, and the upper horizontal elongated member 5 is attached to each crest C of the waveform.
In the width direction of the slope, and fixes the upper laterally long material 5 and the crest C of the net 3. Next, by supporting the upper horizontally long material 5 by at least one of the support means described above, the slack of the mesh body 3 is extended so that the waveform of the mesh body 3 forms a step shape. A step shape is formed as shown in FIG. An earth retaining sheet 6 is stretched on the back side of each riser K of the net 3 having the stairs shape, and the soil is put into the stairs H of the net 3 from the stairs H, and the vegetation is planted. Greening can be achieved. When vegetating a slightly grown plant such as a seedling, the plant is vegetated so that the root of the plant is entangled with the mesh of the net 3. In addition, the retaining sheet 6
It may be already attached to an appropriate part of the net 3 at a factory or the like.

Next, the present invention 6 will be described. A plurality of lower horizontal elongated members 4 are fixed at several places of at least one vertically arranged lower vertical elongated member 11 in a state of being crossed, and the net 3 is loosened between the lower horizontal elongated members 4. A net structure as shown in FIG. 11 is manufactured in advance by stretching the wave form in a state of being held, and fixing each wave bottom portion T of the net body 3 to each lower horizontal elongated member 4.

Then, the prefabricated net structure is inserted into the slope 1
The lower body 3 and / or the lower body 4 are fixed to the slope 1 with at least two fixing members 14 such as anchors. Here, the upper horizontally long material 5 may be already attached in a factory or the like as shown in FIG. 11, but at the construction site, the upper horizontally long material 5 is laid horizontally on each crest C of the waveform of the net body 3 in the slope width direction. Then, the upper horizontally long material 5 and the crest C of the net 3 may be fixed. By supporting the upper horizontally long material 5 by at least one of the support means described above, the slackness of the mesh body 3 is extended, and the waveform of the mesh body 3 forms a step shape, as shown in FIG. A staircase shape is configured as shown. An earth retaining sheet 6 is stretched on the back side of each riser K of the net 3 having the stairs shape, and the soil is put into the stairs H of the net 3 from the stairs H, and the vegetation is planted. Greening can be achieved. When vegetating a slightly grown plant such as a seedling, the plant is vegetated so that the root of the plant is entangled with the mesh of the net 3. Note that the earth retaining sheet 6 may be already attached to an appropriate portion of the net body 3 at a factory or the like.

Next, the present invention 8 will be described. The above-described mesh structure of the present invention 3 (see FIG. 12) is installed on the slope 1, and the lower vertically long material 11 and / or the lower horizontally long material 4 are fixed by at least two fixing members 14 such as anchors. Slope 1
And the soil is thrown in from the stair-shaped tread portion H of the net body 3 and vegetation is planted, so that the slope can be greened. When vegetating a slightly grown plant such as a seedling, the plant is vegetated so that the root of the plant is entangled with the mesh of the net 3.

The soil used for the slope revegetation method of the present inventions 4, 6, and 8 includes soil, vegetation material (peat moss,
Soil improvers such as bark, perlite fine granules, bermlite, and superabsorbent polymer), fertilizers, mixtures of seeds and the like, and other known soils used in various tree planting methods. In addition, construction soil generated at a site or another site can be used as the soil.

FIG. 13 is a schematic explanatory side view showing an example of a state in which the soil 15 is loaded. The muddy soil 15 containing water is used as the soil 15 and the muddy soil 15 is poured from the upper portion of the stepped net 3 by pumping, etc. Overflow and / or dive under the lower part of the earth retaining sheet 6, it is sequentially poured into the lower stage, and can be introduced into the preceding stage by being introduced from above.

FIG. 14 is a schematic sectional view showing an example of a state of vegetation by the above-described slope greening method of the present invention.
As shown in FIG. 14, the roots of the vegetation 16
It can be seen that the net 3 is firmly entangled with the net 3 fixed via the lower horizontally long material 4 to form a stable rhizome. Therefore, tree vegetation is possible.

As described above, according to the present invention, in the operation of installing and fixing the net body 3 in a step shape on the slope 1 to form a greening base, the fixing to the slope 1 is performed by the net 3 Lower long material 4 (and / or lower vertical long material 11) fixed to
Is fixed by the fixing member 14 such as at least two anchors, the lower laterally long material 4 can fix the step-shaped deep portion O constituting the aggregate in the width direction of the slope. . Accordingly, the entire net body 3 can be fixed to the slope 1 only by fixing the peripheral portion of the net body 3, so that a large amount of anchors are driven over the entire area in the width direction of the stairs as in the related art. No need. Particularly, even if the anchor at the center of the net 3 is omitted, the net can be fixed to the slope 1 because the fixing work to the slope 1 is only required at the peripheral portion of the net 3, and the slope 1 is steep. Even in this case, the work is hardly difficult. In the case where the slope 1 is steep or the like, and it is desired to make the fixing more firm, the anchor may be driven into the center portion of the net body 3 or the number of driving may be increased.

Also, the upper horizontal elongated member 5 can secure the position of the stepped portion S in the step shape by the above-mentioned supporting means. Therefore, it is possible to reduce the construction work as compared with the related art in which a large amount of anchors are driven into the slope to secure the crests for bringing the net into a corrugated state.

[0050]

As described above, according to the present invention, a lower laterally long material serving as an aggregate is laid in the step depth of a step-shaped net in the width direction of the slope, and the lower laterally long material is provided on the slope at least two times. It is fixed by a fixing member such as a book anchor, and the upper laterally long material serving as aggregate is laid and fixed in the width direction of the slope at the step end, and a retaining sheet is stretched on the back side of the stair-shaped riser. The entire structure can be fixed to the slope by simply fixing the lower horizontal elongated member to the slope, and such fixing is performed at least two times with respect to the lower horizontal elongated member. This is possible simply by using a book anchor. Therefore, since it is possible to fix to the slope only by fixing the peripheral portion of the net with a fixing member such as an anchor, even if the fixing work on the slope is steep, the work is significantly reduced and a strong Fixation is possible. Each of the long members can be used as a work platform.
Further, since the soil is held for each step by the retaining sheet stretched over the step-shaped riser, the outflow of the soil can be prevented even on a steep slope.

Further, the roots of the vegetated plants are entangled in the mesh of the net fixed to the slope, so that a stable rhizome can be formed. Therefore, tree vegetation can be achieved even on steep slopes. Furthermore, stable rhizome formation is possible even on a hard slope such as a concrete slope on which the root cannot enter the ground.

Further, fallen leaves and the like are deposited on the step-shaped treads, so that the vegetation base is unlikely to decline. Further, since snow is deposited on the tread portion, a deep avalanche can be prevented. Even when a surface avalanche occurs, the rhizome of the plant is stable, so that the plant is not taken up.

Further, due to the presence of the soil retaining sheet, even muddy soil containing water or soil with fine particles can be introduced as the soil.

Further, since the remaining construction soil can be used as the soil and the waste material can be used as the upper horizontal material, the resources can be effectively used and the cost can be reduced.
