FIG. 3 is an enlarged perspective view of the slope greening soil-holding holder 1 according to Embodiment 1 of the present invention, and FIG. It is a front view which shows the state applied to the thing.

  As shown in FIG. 1 to FIG. 3, the slope greening customer soil retainer 1 according to Embodiment 1 is formed on a naturally formed natural slope, or an artificially formed cut slope, that is, a slope S such as a slope. It is provided, and is provided between the vertical frames 2 provided along the inclination direction of the slope S, and at a predetermined interval in the inclination direction. In the example shown in FIG. 1, the horizontal frame is not provided, but in the example shown in FIG. 3, an example in which the horizontal frame 3 is provided so as to connect the upper and lower ends of each vertical frame 2 is shown. It is optional whether the horizontal frame 3 is installed at an upper or lower position of the vertical frame 2 or at intermediate positions.

  As illustrated in FIG. 2, the slope greening soil-holding tool 1 according to the first embodiment includes a mountain-side metal mesh 11 that is a mountain-side porous sheet member provided along the slope S, and a mountain-side porous sheet member 11 on the base end side. While being rotatably connected to the lower end, a plurality of (first embodiment) provided at predetermined intervals along the inclination direction of the slope S as shown in FIG. 6 and FIG. Then, for convenience, it is assumed that there are three). The trough-side metal mesh 12 that is the trough-side porous planar member having the hooked portions 121a to 121c, and the top end of the crest-side metal mesh 11 and the tip of the trough-side metal mesh 12 are as horizontal as possible. And an angle adjustment support fitting 13 connected so as to approach each other.

  Then, as will be described later, the hook portion 132 at the tip of the angle adjustment support fitting 13 rotatably connected to the upper end of the mountain side metal mesh 11 is attached to one of the hooked portions 121a to 121c on the tip side of the valley side metal mesh 12. The planting shelf 10 is constructed by connecting to the latching portion.

  In FIGS. 1 to 3, reference numeral 51 denotes a slope greening customer soil in the planting shelf 10 formed by the slope greening customer soil holder 1 of the first embodiment, and 52 denotes a slope outside the planting shelf 10. It is a land for slope greening on S. In FIG. 3, 21 is a vertical frame reinforcing bar that passes through the vertical frame 2, and 31 is a horizontal frame reinforcing bar that passes through the horizontal frame 3.

  4 (a), 4 (b), 5 (a), and 5 (b) respectively show a greening frame structure constructed using the slope greening soil-holding holder 1 of Embodiment 1 shown in FIG. It is an AA line sectional view, a BB line sectional view, a CC line sectional view, and a DD line sectional view of a thing.

  That is, as shown in FIGS. 4 (a) and 4 (b), the greening method frame structure forms the vertical frame 2 which is a spraying frame after laying the rhombus wire mesh (lass wire mesh) 4 on the slope S, A plurality of planting shelves 10 are configured using the soil-retaining tool 1 for slope greening according to the first embodiment.

  Here, the vertical frame 2 is fixed to the slope S by driving the main anchor 32 into the slope S via a rhombus metal mesh (lass wire mesh) 4. On the other hand, in the greening frame structure constructed using the slope greening soil-holding holder 1 of the first embodiment, the top of the mountain-side wire net 11 and the like is L-shaped through a rhombus metal net (lass wire net) 4. By fixing the shaped planting shelf anchor 14 to the slope S, it is fixed to the slope S. As long as the mountain side wire net 11 can be fixed to the slope S, the planting shelf stopper 14 may of course not have an L-shaped head.

  Then, as shown in FIG. 5A, the hook portion 132 at the tip of the angle adjustment support fitting 13 rotatably connected to the upper end of the mountain side metal mesh 11 is connected to a plurality of hooks of the valley side metal mesh 12 as will be described later. The planting shelf 10 is configured by hooking on one of the stop portions 121a to 121c.

  In addition, as shown in FIG.5 (b), the cross-section circular vertical frame type greening method frame structure is a type which does not use a mold for formation of the vertical frame 2, and sprays cement-type solidification materials, such as mortar. The formed vertical frame 2 has a semicircular cross section.

  That is, the vertical frame 2 is provided with two vertical frame reinforcing bars 21 in the longitudinal direction which is the inclination direction of the slope, and a plurality of metal mesh (lattice) -like shapes are arranged at predetermined intervals in the longitudinal direction of the vertical frame reinforcing bar 21. A spacer 22 that is an auxiliary member for forming a vertical frame is erected to form a framework. Here, when the spacer 22 alone does not stand on the slope S, the anchor 22 is fixed to the slope S by driving an anchor pin under the spacer 22. In the case of the vertical frame 2 of the circular frame type with a circular cross section, since the mold frame is not used, the vertical frame 2 is formed by spraying a cement-based solidifying material such as mortar into a semicircular shape using the spacer 22 as a mark. .

  6 is an overall view showing a state in which the mountain side wire mesh 11 and the valley side wire mesh 12 constituting the slope greening soil-holding holder 1 of Embodiment 1 are connected and expanded, and FIG. 7 is the slope shown in FIG. FIG. 8 is a plan view of the mountain side wire mesh 11 constituting the slope greening customer soil retainer 1 shown in FIG. 6, and FIG. 9 is FIG. It is the whole figure which shows the state which closed the mountain side metal-mesh 11 and the valley | side metal-mesh 12 which comprise the slope greening customer soil holding tool 1 shown in FIG.

  FIG. 10 is a side view showing a side surface of the angle adjusting support fitting 13 constituting the slope greening soil-holding tool 1 according to the first embodiment, and FIG. 11 is a slope greening soil-holding tool according to the first embodiment. 1 is a cross-sectional view showing a state in which a mountain-side metal mesh 11 and a valley-side metal mesh 12 are connected using a support metal fitting 13 that constitutes 1.

  As shown in FIGS. 6 to 9, the mountain side wire mesh 11 and the valley side wire mesh 12 constituting the slope greening soil-holding holder 1 of Embodiment 1 are each made of a thin galvanized iron wire having a diameter of about 2.6 mm. A plurality of vertical lines 112 and 122 and horizontal lines 111 and 121 are formed of a crimped wire mesh braided vertically and horizontally. Note that the mountain side wire mesh 11 and the valley side wire mesh 12 are not limited to the crimp wire mesh, and are porous members having a large number of openings such as a welded wire mesh, a net-like member such as an expanded metal or a lath wire mesh, or a punching metal. What is necessary is just to be comprised from the planar member.

  As shown in FIG. 10, the angle adjustment support fitting 13 is provided with a ring portion 131 rotatably connected to the upper end of the mountain side metal mesh 11 on the base end side, and on the tip side, the valley side metal mesh 12. A hook portion 132 that is hooked to one of the three hooked portions 121a to 121c on the distal end side is provided. In addition, the ring part 131 shown in FIG. 10 has shown the state before connecting with the upper end part of the mountain side metal mesh 11 so that rotation is possible, and is still U-shaped, and is connected with the upper end part of the mountain side metal mesh 11 so that rotation is possible. After being done, it is crushed into a ring shape so as not to come off from the mountain side wire net 11. Moreover, the hook part 132 is detachable so that it can be selectively hooked to one of the hooked parts 121a to 121c of the valley wire mesh 12 according to the situation of the construction site. It is formed in a so-called gourd shape that is difficult to remove. In addition, these shapes are arbitrary, and the point is not particularly limited as long as the upper end of the mountain side metal mesh 11 and the upper end of the valley side metal mesh 12 can be connected at an angle as close to horizontal as possible.

  And as shown in FIG. 6 etc., the mountain side wire mesh 11 and the valley side wire mesh 12 have a lower end of the mountain side wire mesh 11 and an upper end that is a base end of the valley side wire mesh 12 at a plurality of locations (in FIG. 7), each of them is rotatably connected by a connecting ring 15 or the like. The state shown in FIG. 6 shows a state in which the mountain side wire mesh 11 and the valley side wire mesh 12 are spread through the connection ring 15, and when the mountain side wire mesh 11 and the valley side wire mesh 12 are closed through the connection ring 15. 9 is folded through the connecting ring 15 as shown in FIG. 9, and the space efficiency is improved during storage and transportation. In the present embodiment, the mountain side wire mesh 11 and the valley side wire mesh 12 are rotatably connected via the connection ring 15. However, the present invention is not limited to this, and the connection ring 15 is not used. Of course, the mountain side wire mesh 11 and the valley side wire mesh 12 may be connected so as to be directly rotatable.

  Moreover, in FIG. 6, 113 has shown the position where the ring part 131 of the angle adjustment support metal fitting 13 is connected so that rotation is possible, and it is four places here.

  Here, as shown in FIG. 6 and FIG. 9, the longitudinal length of the mountain side metal mesh 11, that is, when installed on the slope S, the lateral length perpendicular to the slope direction of the slope S is defined as the valley side metal mesh 12. The both ends in the longitudinal direction of the mountain side metal mesh 11 form both end projecting portions 11 a and 11 b that project from both ends in the longitudinal direction of the valley side metal mesh 12. This is because the protrusions 11a and 11b on both ends of the mountain side metal mesh 11 are positioned or fixed by crossing or connecting to the vertical frame reinforcing bars 21 and spacers 22 of the vertical frames 2 on both sides, and the valley side metal mesh 12 is on the vertical side of the both sides. This is to enable standing up without interfering with the frame 2. Here, the length in the longitudinal direction of the mountain-side wire mesh 11 is about 1700 mm and the distance between the vertical frame reinforcing bars 21, and the length in the longitudinal direction of the valley-side wire mesh 12 is about 1400 mm and is approximately between the inside of the vertical frame 2 after molding. And the distance.

  On the other hand, as shown in FIGS. 6 to 9, the length of the mountain side wire mesh 11 in the short direction, that is, the length in the vertical direction, which is the inclination direction of the slope S when installed on the slope S, is shorter than the trough side wire mesh 12. The length of the direction is the same. Here, the length of both is about 250 mm in common.

  Further, as shown in FIG. 6 and FIG. 7, the number of horizontal lines 111 that are the longitudinal direction of the mountain side wire mesh 11 is made smaller than the number of horizontal lines 121 in the longitudinal direction of the valley side wire mesh 12. This is because the mountain side wire mesh 11 is installed directly on the slope S or via a lath wire mesh (rhombus wire mesh), so that even if the gap is large, the greening customer soil 51 can be prevented from falling and falling off, and is uneven. This is because it is necessary to make it easy to bend so that the mountain-side wire net 11 is installed along the uneven slope S as much as possible.

  On the other hand, as shown in FIG. 6 and FIG. 8 and the like, the valley-side metal mesh 12 does not increase the number of horizontal lines 121 in the longitudinal direction, so that the greening customer soil 51 falls or drops off. Note that the number and thickness of the vertical lines 112 and 122 and the horizontal lines 111 and 121 of the mountain side wire mesh 11 and the valley side wire mesh 12 and the length thereof are arbitrary.

  Further, in the slope greening soil-holding tool 1 of Embodiment 1, as shown in FIGS. 6 and 8, etc., a horizontal line 121 extending in the longitudinal direction is used on the tip side of the valley-side wire mesh 12. A predetermined interval (here, for example, about 210 mm) is provided along the inclination direction of the slope S, which is larger than the height of the hook portion 132, so that the hook portion 132 at the tip of the angle adjustment support fitting 13 can be inserted. Even if the slope α of the slope S changes, a plurality of (here, for convenience, use the horizontal lines 121 extending in the longitudinal direction so that the tip of the valley-side wire mesh 12 and the upper end of the mountain-side wire mesh 11 are as close to horizontal as possible. The number of hooked portions 121a to 121c is 3). As a result, the interval between the plurality of hooked portions 121a to 121c is made larger than the interval between the horizontal lines 121 other than the hooked portions 121a to 121c. Of course, the number of the hooked portions 121a to 121c is not limited to three, and may be two or four or more, and of course, the hooked portions 121a to 121c may be provided independently without using the horizontal line 121. good.

  Here, when the hook portion 132 at the distal end of the angle adjustment support metal fitting 13 is hooked on the hooked portion 121a on the base end side among the three hooked portions 121a to 121c on the tip end side of the trough-side metal mesh 12, the slope S When the slope α is latched on the 8-minute gradient of about 51 degrees and the central hooked portion 121b, the slope α of the slope S is about 63-degree five-minute slope and latched on the hooked portion 121c on the tip side. The slope α of the slope S corresponds to a 3-minute slope of about 73 degrees.

  In FIG. 11, the slope α of the slope S is close to a 5-minute slope of about 63 degrees, so that the hook portion 132 at the tip of the angle adjustment support bracket 13 is hooked on the hooked portion 121 b at the center of the valley-side metal mesh 12. Thus, the upper end of the mountain side wire mesh 11 and the tip of the valley side wire mesh 12 are connected so as to be substantially horizontal.

  Thereby, even if the gradient α of the slope S changes, the hook portion 132 at the tip of the angle adjustment support fitting 13 is hooked on one of the plurality of hooked portions 121a to 121c of the valley side metal mesh 12. As a result, the trough side wire mesh 12 can be raised at an arbitrary standing angle of about 51 degrees, about 63 degrees, or about 73 degrees with the lower end of the mountain side wire mesh 11 as the center, improving workability and work efficiency. Can be made.

  As a result, regardless of the slope of the slope S, the top of the mountain-side wire mesh 11 and the tip of the valley-side wire mesh 12 can be set almost horizontally. It is possible to prevent outflow of the slope greening soil 51 on the shelf 10 and the planting trees 51 that grow from the slope greening soil 51. Since the upper end of the mountain side wire net 11 and the tip end of the valley side wire net 12 of the sloped greening customer soil holding tool 1 are unified almost horizontally, the whole is well-balanced and the landscape is also improved.

  FIG. 12 is a diagram showing a state in which the green soil for landscaping (vegetation base material) is sprayed after the slope greenery soil keeper 1 of the first embodiment is installed on the slope S.

  As shown in FIG. 12, after installing the slope greening soil-holding holder 1 according to the first embodiment on the slope S, the operator holds the vegetation base material feeding hose 6 and the like, and seeds of various greening plants. Planting soils (vegetation base materials) 51 and 52 mixed with fertilizer and the like, the interior of the planting shelf 10 constituted by the soil planting holder 1 for slope greening of the first embodiment, and the planting shelf 10 Spray on the slope S between the vertical frames 2. At that time, for example, if the land for planting (vegetation base material) 51 to be sprayed into the planting shelf 10 includes seeds or seedlings of larger trees that are taller, the planting shelf 10 is used. As roots grow on the slope S, it is convenient. In addition, the planting soil (vegetation base material) 52 to be sprayed on the slope S other than the planting shelf 10 may be a short plant seed or seedling. In addition, in order to plan the greening of the surface by the side of the trough side metal-mesh 12 of the planting shelf 10, you may provide a nonwoven fabric and a greening sheet in the surface. Moreover, you may make it mix a water retention material in a customer's soil for the purpose of the moisture maintenance of a customer's soil.

<< Rectangular vertical frame type greening frame structure >>
Next, a case where the slope greening soil-holding holder 1 according to Embodiment 1 is applied to a greening method frame structure of a rectangular vertical section type will be described.

  FIG. 13 is a front view showing a state of a greening method frame structure of a cross-sectional rectangular vertical frame type installed on a slope at a construction site using the slope greening soil-holding tool 1 or the like, FIG. 14 (a), (b) ) Are a cross-sectional view taken along the line E-E and a cross-sectional view taken along the line F-F, respectively.

  As apparent from FIGS. 13 and 14, the green frame method frame structure of the rectangular cross section vertical frame type is formed by spraying a vertical frame 2 ′ formed by spraying a cement-based solidifying material such as mortar into a rectangular cross section. Thus, it is a type that uses a mold for forming the vertical frame 2 ', and the other configuration is the same as that of the vertical frame type green frame usage frame structure shown in FIGS. .

  That is, as shown in FIG. 14 (b), the vertical frame 2 'of the greening method frame structure of a rectangular vertical frame type section is composed of a grid-like separator 22' and a crimp wire mesh 23 'provided on both sides thereof. Four vertical frame reinforcing bars 21 ′ are fixed to the crossing portion of the separator 22 ′ with respect to the metal mesh form 24 ′, and a cement-based solidifying material such as mortar is sprayed toward this.

Therefore, according to the slope greening soil-holding holder 1 of the first embodiment, the mountain side wire mesh 11 and the valley side wire mesh 12 are folded during storage and transportation, while the mountain side wire mesh 11 is moved along the slope during construction. On the other hand, the trough-side metal mesh 12 is supported by being set at an arbitrary standing angle by the angle adjusting support metal fitting 13 so that the top end of the crest-side metal mesh 11 and the tip of the trough-side hole net 12 approach the horizontal, and the standing angle is set. Since the slope greening customer soil 51 is held between the mountain-side wire mesh 11 and the valley-side wire mesh 12, for example, the following effects can be obtained.
(1) Since the mountain side wire net 11 and the valley side hole net 12 can be folded and stored or transported, the space efficiency during storage, the work efficiency during transport, and the like can be improved.
(2) Since the standing angle can be set so that the upper end of the mountain side wire net 11 and the tip of the valley side hole net 12 approach horizontally, the slope greening on the planting shelf 10 formed by the slope soil greening customer soil retainer 1 It is possible to prevent outflow of the plant land 51 and the vegetation grown from the slope greening soil 51, and to grow the planting with little loss of the slope greening soil 51.
(3) Since the upper end of the mountain-side wire net 11 and the tip of the valley-side hole net 12 of the slope greening soil-holding fixture 1 installed on the entire slope S are unified almost horizontally, as shown in FIG. The entire construction site of the wide greening frame structure is well-balanced and the landscape is also good.

  Further, in the slope greening soil-holding tool 1 according to the first embodiment, the length in the longitudinal direction of the mountain side wire mesh 11 that is perpendicular to the slope direction of the slope S is greater than the length in the longitudinal direction of the valley side wire mesh 12. Since both ends of the mountain-side wire mesh 11 are formed with both end protrusions 11a and 11b protruding from both ends of the trough-side wire mesh 12 in the longitudinal direction, the both-end protrusions 11a and 11b of the mountain-side wire mesh 11 are respectively formed. It can be connected to and fixed to the left and right vertical frames 2, and the slope greening soil-holding fixture 1 can be reliably positioned and fixed, so that workability can be improved and both ends of the trough-side metal mesh 12 can be improved. Is less likely to interfere with the vertical frame 2 or the vertical frame rebars 21, 21 ′ constituting the vertical frame 2, the spacer 22, or the metal mesh formwork 24 ′. This also improves workability. Whether or not to adopt such a configuration is arbitrary.

  Moreover, in the slope greening soil-holding tool 1 of the first embodiment, the valley-side wire mesh 12 extends in a direction perpendicular to the plurality of vertical lines 122 extending in the inclination direction of the slope S and the inclination direction of the slope S. The plurality of hooked portions 121a to 121c are provided with a plurality of horizontal lines 121 at predetermined intervals along the inclination direction of the slope S. Since the interval between the plurality of hooked portions 121a to 121c is larger than the interval between the horizontal lines 121 other than the hooked portions 121a to 121c, the hook portion 132 at the tip of the support fitting 13 is inserted, The hooks 121a to 121c can be easily hooked, and workability can be improved in this respect. Whether or not to adopt such a configuration is arbitrary.

Embodiment 2. FIG.
Next, the slope soil greening soil-holding tool 1 'according to the second embodiment will be described.

  FIG. 15 is an overall view showing a state in which the mountain side wire mesh 11 ′ and the valley side wire mesh 12 ′ constituting the slope greening soil-holding tool 1 ′ of Embodiment 2 are connected and expanded.

  Although it is clear when compared with the mountain side wire mesh 11 and the valley side wire mesh 12 that constitute the slope greening soil-holding tool 1 of the first embodiment shown in FIG. A plurality of hooked portions 121 a to 121 c provided at predetermined intervals along the inclination direction of the slope S are provided on the tip side of the valley side wire mesh 12, and the ring portion 131 of the angle adjustment support fitting 13 is connected to the mountain side wire mesh. 11, the hook portion 132 at the tip of the angle adjustment support fitting 13 is hooked on one of the plurality of hooked portions 121 a to 121 c of the valley side metal mesh 12.

  On the other hand, in the slope greening soil-holding implement 1 ′ according to the second embodiment, a plurality of hooks provided at predetermined intervals along the inclination direction of the slope S on the upper end side of the mountain side wire net 11 ′. 111a ′ to 111c ′ are provided, and the ring portion 131 of the angle adjustment support fitting 13 is rotatably connected to the tip end portion of the valley side metal mesh 12 ′, while the hook portion 132 at the tip end of the angle adjustment support fitting 13 is connected to the mountain side metal mesh 11. The only difference is that it is configured so as to be hooked to one of the plurality of hooked portions 111a 'to 111c'.

  As described above, even when the slope greening soil-holding tool 1 ′ according to the second embodiment is configured, like the slope greening soil-holding tool 1 according to the above-described first embodiment, the mountain side is stored or transported. It is possible to fold and overlap the metal mesh 11 ′ and the valley metal mesh 12 ′, and it is possible to improve the space efficiency during storage, the work efficiency during transportation, and the like. Even if the slope α of S changes, by changing the plurality of hooked portions 111 a ′ to 111 c ′ of the mountain side wire mesh 11 ′ on which the hook portion 132 at the tip of the angle adjustment support bracket 13 is hooked, the upper end of the mountain side wire mesh 11 ′ Since the tip of the valley-side wire mesh 12 ′ can be held to be set substantially horizontal, the same effect as the above-described slope greening customer soil retainer 1 of the first embodiment can be obtained.

  In the first and second embodiments, the valley side porous surface member, the mountain side porous surface member, the angle adjustment support member, etc. of the present invention are made of the metal mountain side metal mesh 11, the valley side metal mesh 12, and the angle adjustment. In the present invention, the support bracket 13 and the like have been described. However, the present invention is not limited to this, and it is needless to say that these members may be configured by other members such as plastic other than metal.

  In addition, the slope greening soil-holding tool according to the present invention may of course be mixed with various base materials as long as it prevents the slope greening soil to be sprayed against the slope S from sliding down. In addition, the application form of the soil retaining tool for slope greening according to the present invention may be a natural slope S such as a natural mountain, a slope S that has been created, or a slope S that has been previously covered with concrete or mortar. This method can be applied to the case where greening is attempted by spraying the soil for slope greening on the surface.
