After that, those construction methods will be explained. The slope in the present invention is a natural slope formed naturally, a cut slope that is artificially formed, that is, a slope.

≪Green cross-section frame structure for greening≫
First, as an example of the greening usage frame structure according to the present invention, an embodiment of a greening usage frame structure of a cross-sectionally rounded vertical frame type will be described.

  FIG. 1 is a perspective view showing an example of a greening method frame structure in a state of greening on a slope after a certain period of time has been installed on the slope S, and FIG. 2 is provided between the vertical frames 2. FIG. 3 is an enlarged perspective view showing the slope greening soil-holding holder 1 for one row, and FIG. 3 shows a state in which the slope-greening soil-holding holder 1 is applied to a green frame method frame structure with a cross-sectionally round frame. FIG.

  As shown in FIGS. 1 to 3, the slope greening soil-holding tool 1 is provided on a naturally formed natural slope, or an artificially formed cut slope, that is, a slope S such as a slope. And 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 shown in FIG. 2, the slope greening soil-holding tool 1 is rotated along a mountain-side metal mesh 11 that is a mountain-side porous sheet member provided along the slope S, and a base end side is rotated to the lower end of the mountain-side porous sheet member 11. On the other hand, a plurality of (here, three are provided for convenience) provided at predetermined intervals along the inclination direction of the slope S as shown in FIG. 6 and FIG. Angle-adjusting support that connects the valley-side metal mesh 12 that is the valley-side porous planar member having the hooked portions 121a to 121c, and the upper end of the mountain-side metal mesh 11 and the tip of the valley-side metal mesh 12 as close as possible to the horizontal. And a metal fitting 13.

  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 soil in the planting shelf 10 formed by the slope greening soil holder 1, and 52 denotes a slope S outside the planting shelf 10. It is a land for slope greening. In FIG. 3, reference numeral 21 denotes vertical frame reinforcing bars 21 and 31 that pass through the vertical frame 2, and horizontal frame reinforcing bars that pass through the horizontal frame 3.

  4 (a), 4 (b), 5 (a), and 5 (b) respectively show a cross-section lacking circular vertical frame type revegetation method constructed using the slope greening soil-holding holder 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 frame structure.

  That is, as shown in FIGS. 4A and 4B, the green frame method for greening with a cross-sectionally lacking vertical frame type is a spray frame after the rhombus wire mesh 4 is laid on the slope S. A vertical frame 2 is formed, and a plurality of planting shelves 10 are configured by using the soil holding tool 1 for slope greening.

  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, the greening frame structure constructed by using the slope greening soil-holding tool 1 is a planting shelf having an L-shaped head at the upper end of the mountain-side wire net 11 via a rhombus wire net 4 The stop anchor 14 is fixed to the slope S by driving it into 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 circular 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. .

  FIG. 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 tool 1 are connected and widened, and FIG. 7 is the slope greening site soil holding shown in FIG. FIG. 8 is a plan view of a valley-side wire net 12 constituting the slope greening customer-holding tool 1 shown in FIG. 6, and FIG. 9 is a slope greening view shown in 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 customer soil holding tool 1.

  FIG. 10 is a side view showing the side surface of the angle adjustment support fitting 13 constituting the slope greening soil-holding fixture 1, and FIG. 11 shows the support fixture 13 constituting the slope greening soil-holding fixture 1. It is sectional drawing which shows the state which connected the mountain side metal-mesh 11 and the valley | side metal-mesh 12.

  As shown in FIGS. 6 to 9, each of the mountain side wire mesh 11 and the valley side wire mesh 12 constituting the slope greening customer soil retainer 1 is a plurality of vertical lines made of a thin galvanized iron wire having a diameter of about 2.6 mm. 112 and 122 and horizontal lines 111 and 121 are composed of a crimp wire mesh or the like 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 upper end of 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 protruding portions 11a and 11b of the mountain side metal mesh 11 are crossed or connected to the vertical frame reinforcing bars 21 and the spacers 22 of the vertical frames 2 on both sides, and positioned and fixed. This is so that the robot can stand up without interfering with the motor 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 valley-side wire mesh 12 is raised at an arbitrary standing angle of about 51 degrees, about 63 degrees, and about 73 degrees around the lower end of the mountain-side wire mesh 11, and the upper end of the mountain-side wire mesh 11 and the tip of the valley-side wire mesh 12 are Can be connected so as to be substantially horizontal, so that workability and work efficiency can be improved.

  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 illustrating a state in which the green soil customer (vegetation base material) is sprayed after the slope green planting soil holder 1 is installed on the slope S.

  As shown in FIG. 12, after installing the slope greening soil-holding holder 1 on the slope S, the operator holds the vegetation base material feeding hose 6 and the like, and the seeds and fertilizers of various greening plants are mixed. The greening customer soil (vegetation base materials) 51 and 52 are sprayed on the planting shelf 10 constituted by the customer planting holder 1 for slope greening or the slope S between the planting shelf 10 and the vertical frame 2. At this time, for example, if the greening soil (vegetation base material) 51 sprayed on the planting shelf 10 includes seeds or seedlings of larger trees that are taller, the slope through the planting shelf 10 Since it grows rooted in 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 of the planting shelf 10 on the valley side wire net 12 side, a corrosive cloth or a greening sheet may be provided on the surface. Moreover, you may make it mix a water retention material in the soil for slope greening for the purpose of the water | moisture content retention of the soil for slope greening.

Therefore, according to the green frame method frame structure of the present embodiment to which the above-mentioned slope greening soil holding tool 1 is applied, the slope greening soil holding tool 1 is stored or transported. While the mountain-side wire mesh 11 and the valley-side wire mesh 12 are folded, the mountain-side wire mesh 11 is provided along the slope at the time of construction, while the valley-side wire mesh 12 is placed so that the upper end of the mountain-side wire mesh 11 and the tip of the valley-side wire mesh 12 approach horizontally. In addition, since the angle adjustment support bracket 13 supports and supports an arbitrary standing angle, the slope greening customer soil 51 is held between the mountain-side wire mesh 11 and the valley-side wire mesh 12 set to the standing angle. 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.

  In addition, according to the green frame method frame structure of the cross-sectionally lacking vertical frame type of the present embodiment, the length of the mountain-side wire mesh 11 in the longitudinal direction, which is perpendicular to the inclination direction of the slope S, is Since both ends in the longitudinal direction of the mountain side metal mesh 11 are formed longer than the length in the longitudinal direction, and both end projections 11 a and 11 b project from both ends in the longitudinal direction of the valley side metal mesh 12, both end projections of the mountain side metal mesh 11 are formed. 11a and 11b can be connected and fixed to the left and right vertical frames 2, respectively, and the slope greening soil-holding fixture 1 can be reliably positioned and fixed, improving workability and improving the trough-side wire mesh 12. Since it becomes difficult to interfere with the vertical frame 2 or the vertical frame reinforcing bar 21 constituting the vertical frame 2 or the spacer 22, both ends of the can easily cause the trough-side wire mesh 12, and the workability is improved in this respect as well. Whether or not to adopt such a configuration is arbitrary.

  Moreover, in the green frame method frame structure of the present embodiment, the valley-side metal mesh 12 is 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 the workability can be improved in this respect. Whether or not to adopt such a configuration is arbitrary.

<< Rectangular vertical frame type greening frame structure >>
Next, as another example of the greening usage frame structure according to the present invention, an embodiment of a greening usage frame structure having a rectangular cross-sectional frame 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 cross-sectional rectangular vertical frame type greening frame structure is formed by spraying a cement-based solidifying material such as mortar into a rectangular frame 2 ′. In this type, the form frame is used to form the vertical frame 2 ′. Therefore, the configuration other than the vertical frame 2 ′ is the same as that of the green frame usage frame structure of a circular frame type with a cross section not shown in FIGS. 1 to 12.

  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 intersection of the separator 22' with respect to the metal mesh form 24 ', and cemented solidified material such as mortar is sprayed toward the metal mesh form 24'.

  Therefore, according to the greening method frame structure of the cross-sectional rectangular vertical frame type of the present embodiment to which the slope greening soil-holding fixture 1 is applied, Similar effects can be obtained.

≪An example of other soil holding tool 1 'for greening of slopes≫
Next, an example of another soil holding tool 1 ′ for slope greening will be described. The slope greening soil-holding tool 1 ′ is similar to the slope greening soil-holding tool 1 in the above-mentioned cross-sectionally lacking circular vertical frame type greening frame structure. It can also be applied to usage frame structures.

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

  It is clear when compared with the mountain side wire mesh 11 and the valley side wire mesh 12 that constitute the slope greening customer soil holding tool 1 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, and the ring portion 131 of the angle adjustment support fitting 13 is rotatably connected to the upper end of the mountain side metal net 11. On the other hand, the hook portion 132 at the tip of the angle adjustment support metal 13 is configured to be hooked on one of the plurality of hooked portions 121a to 121c of the valley side metal mesh 12.

  On the other hand, in the other soil holding tool 1 ′ for slope greening, a plurality of hooked portions 111 a ′ provided at predetermined intervals along the slope direction of the slope S on the upper end side of the mountain side wire net 11 ′. ˜111c ′, 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 plurality of mountain side metal meshes 11 ′. The only difference is that it is configured to be hooked to one of the hooked portions 111a ′ to 111c ′.

  In this way, even if the other slope greening soil-holding fixture 1 ′ is configured, the mountain side wire mesh 11 ′ and the valley side during storage and transportation are the same as the other slope greening soil-holding fixtures 1 ′ described above. It is possible to fold and overlap the wire mesh 12 ′, and it is possible to improve the space efficiency during storage and the work efficiency during transportation, and the slope α of the slope S changes according to the slope of the slope S. Even so, by changing the plurality of hooked portions 111a ′ to 111c ′ of the mountain-side wire mesh 11 ′ to which the hook portion 132 at the tip of the angle adjusting support fitting 13 is hooked, the upper ends of the mountain-side wire mesh 11 ′ and the valley-side wire mesh 12 ′ are changed. Since it can hold | maintain which sets a front-end | tip substantially horizontal, the effect similar to the case of the above-mentioned other soil-retaining tool 1 for greening of a slope is acquired.

≪Example of construction method for greening frame structure≫
Next, an example of the construction method of the greening method frame structure of the cross-sectionally lacking vertical frame type and the greening method frame structure of the cross-sectional rectangular vertical frame type, which are specific examples of the greening method frame structure according to the present invention described above This will be described with reference to the flowchart shown in FIG. In addition, since this construction method is comprised from a reinforcing bar arrangement | positioning process-a visitor land spraying process as shown in FIG. 16, it will separate about each process.

(1) Reinforcing bar arrangement process In the reinforcing bar arrangement process, the vertical frame rebars 21 and 21 ′ are arranged in parallel at predetermined positions on the slope S. At that time, as a pre-stage before the arrangement of the vertical frame rebars 21 and 21 ′, a rhombus wire mesh (lass wire mesh) is used to hold the slope greening customer soils 51 and 52, particularly the slope greening customer soil 52 sprayed on the slope S. 4 may be laid on the slope S. However, in the vertical direction of the slope S, the rhombus metal mesh 4 may be omitted when the interval between the slope greening soil-holding holders 1 becomes small.

(2) Guest soil holder arrangement process In the customer soil holder arrangement process, the mountain side wire mesh 11 and the valley side wire mesh 12 which constitute the slope greening customer soil holder 1 are expanded on the slope S. At that time, the mountain-side wire mesh 11 is positioned above the slope S, and both end protrusions 11a and 11b (see FIG. 6 and the like) at both ends of the mountain-side wire mesh 11 are arranged so as to intersect the vertical frame rebars 21 and 21 ′. . And the side edge part of the longitudinal direction used as the upper end of the mountain side metal-mesh 11 is fixed to the slope S with the planting shelf stop anchor 14 (refer Fig.5 (a)). In addition, this customer earth holding tool arrangement process and the above-mentioned reinforcing bar arrangement process do not need to be in this order, the order is changed, the earth earth holding element arrangement process is performed first, and then the reinforcing bar arrangement process is performed. Anyway. That is, the vertical frame rebars 21 and 21 'may be installed first, and then the slope greening soil-holding fixture 1 may be placed. Conversely, the slope greening soil-holding fixture 1 may be placed. After that, either of the vertical frame rebars 21 and 21 'may be installed.

(3) Auxiliary member forming step for forming a vertical frame Next, in the auxiliary member forming step for forming a vertical frame, a vertical frame of each vertical frame type that serves as a guide when spraying cement-based solidifying material such as mortar around the vertical frame rebar. The forming auxiliary member is disposed along the vertical frame reinforcing bar. Specifically, in the case of the green frame method frame structure of the cross-sectionally lacking circular vertical frame type described above, as shown in FIG. 5B and the like, along the two vertical frame reinforcing bars 21 at predetermined intervals. Spacer 22 is arranged. On the other hand, in the case of a green frame usage frame structure with a rectangular vertical frame type, as shown in FIG. 14 (b) and the like, along the four vertical frame reinforcing bars 21 ', the cross-shaped separator 22' and its both sides A wire mesh form 24 'made of a crimp wire mesh 23' or the like provided in the above is disposed. At that time, the number of reinforcing bars 21 ′ in the reinforcing bar arrangement step is limited to two, and after the wire mesh form 24 ′ is arranged, the remaining reinforcing bars 21 ′ are installed at the intersections above the separator 22 ′.

(4) Valley Side Wire Mesh Standing Step In the valley side wire mesh standing step, an angle at which the valley side wire mesh 12 below the mountain side wire mesh 11 fixed to the slope S is erected and is pivotally connected to the upper end of the mountain side wire mesh 11. The hook portion 132 at the tip of the adjustment support fitting 13 is hooked on one of the hooked portions 121a to 121c at the tip of the valley side wire net 12 to complete the planting shelf 10. At that time, one of the three hooked portions 121a to 121c is selected and latched so that the upper end of the mountain-side wire mesh 11 and the tip of the valley-side wire mesh 12 are as horizontal as possible. . As shown in FIG. 15, the base end portion of the angle adjustment support fitting 13 is rotatably provided at the distal end portion of the valley side metal mesh 12 ′, and the hooked portion 111a ′ is provided at the distal end side of the mountain side metal mesh 11 ′. ˜111c ′ is provided, the hook portion 132 at the tip of the angle adjustment support fitting 13 is placed on one of the hooked portions 111a ′ to 111c ′ on the tip side of the mountain side metal mesh 11 ′. Try to hang it.

(5) Cement-based solidifying material spraying process In the cement-based solidifying material spraying process, cement-based solidifying material such as mortar is sprayed around the vertical frame reinforcing bars and auxiliary members for vertical frame formation in each vertical frame type. Complete 2, 2 '. Specifically, in the case of a vertical frame type greening frame structure with a cross-section, as shown in FIG. 5B and the like, a cement is formed around the vertical frame reinforcement 21 and the spacer 22 with the spacer 22 as a target. Spray the solidified material. On the other hand, in the case of a greening method frame structure having a rectangular vertical frame type, as shown in FIG. 14 (b) and the like, a wire mesh mold comprising a grid-like separator 22 'and a crimp wire mesh 23' provided on both sides thereof. Cement-based solidifying material is sprayed on and around the frame 24 '.

  Note that this cement-based solidifying material spraying step and the above-described valley-side wire mesh standing-up step do not have to be in this order, the order is changed, the cement-based solidifying material spraying step is performed first, and then the valley-based wire mesh standing-up step is performed. You may make it perform a side wire-mesh standing process. That is, the trough-side wire mesh 12 is first raised to complete the planting shelf 10, and then the cement-based solidified material is sprayed to complete the vertical frame 2, and conversely, the cement-based solidified material is sprayed vertically. After the frame 2 is completed, either one may be used so that the valley side wire net 12 is raised to complete the planting shelf 10.

  This is because both have advantages and disadvantages depending on the situation of the construction site. In other words, depending on the slope of the slope S, the predetermined interval for providing the slope greening soil-holding fixture 1, etc., after the other valley side wire net 12 is erected by the valley side wire mesh erecting step, the cement type solidifying material spraying step is performed. When the cement-based solidifying material such as mortar is sprayed, the hose 6 is caught on the raised valley-side metal mesh 12 when the vegetation base material pressure-feeding hose 6 (see FIG. 12) is moved. It is possible to become. In such a case, a cement-based solidifying material spraying step is performed before the valley side wire netting step.

  On the contrary, depending on the slope of the slope S and the predetermined interval for providing the slope greening soil-holding tool 1, the cement-based solidifying material such as mortar in the cement-based solidifying material spraying process may be applied after the spraying operation. When the valley side wire mesh 12 is erected in the valley side wire mesh standing process, the cement-based solidified material such as mortar scattered near the vertical frames 2 and 2 'adheres to the valley side wire mesh 12 and rises up. This is because inhibition is also considered. In such a case, the valley side wire net standing process is performed first, and then the cement-based solidifying material spraying process is performed.

(6) Customer soil spraying process Finally, in the customer soil spraying process, as shown in FIG. 12 described above, an operator holds the vegetation base material feeding hose 6 and the like, and seeds of various planting plants. The slope greening soil (vegetation base material) 51 mixed with fertilizer and the like is sprayed into the planting shelf 10 constituted by the slope greening soil soil holder 1. Here, not only the inside of the planting shelf 10 but also the slope greening on the slope S surrounded by the vertical frames 2, 2 'in the left-right direction and the planting shelf 10 in the vertical direction (vegetation base material) 52 may be sprayed.

  By the construction method as described above, a cross-section circular vertical frame type greening method frame structure and a cross-sectional rectangular vertical frame type greening method frame structure, which are specific examples of the greening frame structure according to the present invention, are completed. To do.
