  Embodiments of the present invention will be described below with reference to the drawings.

First, the guide material according to the present embodiment will be described.
The guide material A according to the present embodiment is a member for placing the biodegradable frame material continuously at the four corners of the rhombus-shaped frame when the frame is constructed by continuously arranging the frame material. .

<1> Overall Shape FIG. 1 shows a first embodiment of the guide material.
The guide material A according to FIG. 1 has two sets of parallel plates 10 made up of two plates arranged in parallel with a gap between them, and is arranged so as to intersect them.
As a structure for arranging the parallel plates 10 so as to cross each other, a known method such as a structure in which notches are provided in the respective parallel plates may be adopted.
Therefore, the guide material has a shape like “#” or “well” in plan view.

<2> Selection of material Each member which comprises a guide material can be comprised from a biodegradable material.
Biodegradable materials include biodegradable resins, wood, paper, and all other materials having a biodegradable function.
Which of these biodegradable materials is to be selected may be determined as appropriate in consideration of the required strength and the period until decomposition.
Among these, in this embodiment, the guide material is a mixture of at least a granular material and a solidifying agent containing a food-derived component having a solidifying action or a natural-derived component as an active ingredient, and has a biodegradable solidification. A molded body is used.
Hereinafter, the details of the solidified molded body will be described.

<2-1> About solidified molding [granular material]
As the granular material, it is possible to use soil, sand, gravel, stones, or a mixture thereof, and those collected from on-site soil or those separately arranged.
[Solidifying agent]
As the solidifying agent, a food-derived or naturally-derived component having a solidifying action on the granular material is used as an active ingredient.
This biodegradable solidified component is egg white (ovalbumin), collagen, casein, gelatin, chitosan and the like. Since these components are derived from foods, they have a small load on the natural environment and have degradability (disintegration).
In addition, a biodegradation solidification component will not be restricted to the said component if it has a soil solidification effect | action and is a food origin or a natural origin component.
[Other admixtures]
In addition, when a biodegradable cross-linking agent is further added to the solidifying agent, the biodegradable solidified components are cross-linked to obtain a solidified molded body with higher strength.
Moreover, in order to change the density of a solidification molding, you may use the foaming material derived from a foodstuff.

<2-2> Method for Producing Solidified Molded Body An example of a method for producing a solidified molded body will be described.
The composition blended as described above is kneaded after using a soil mixer or the like. At this time, it is desirable to uniformly mix biodegradable solidified components such as egg white into the soil. Thereafter, a predetermined amount of water (such as tap water) is added and kneaded until uniform.
Subsequently, a predetermined amount of a crosslinking agent (urea, SDS, etc.) is added and further kneaded. And after becoming uniform, it pours into a predetermined mold, and is dried for about 3 days in the range of 50 to 100 ° C., and is dried and cured under the same temperature conditions for about 3 days after demolding to obtain a solidified molded body. . The drying time is appropriately adjusted depending on the size of the molded body.
By appropriately changing these blends, the properties (such as porosity, strength, water permeability, and water solubility) of the solidified molded product can be appropriately adjusted.

<3> Selection of strength When providing the guide material A with a worker's stepping function, the guide material A is adjusted by adjusting the composition of the solidified molded body or changing the overall shape of the guide material A. It is desirable that the strength of A is higher than that of the legal frame material.

<4> Name of Each Part Details of each part of the guide material A according to FIG. 1 will be described.
[Inside corner]
The corner portions 30 are provided at the four corners of the outer periphery of the guide material.
By abutting the tip of the scale material 60 to be described later against the corner portion 30, the arrangement position of the guide material A can be accurately determined.
[Containment space]
In places other than the four corners on the outer periphery of the guide material A, there is a space (accommodating space 40) that is sandwiched between parallel plates. By accommodating the end portion of the frame member 70 to be described later in the storage space 40, the arrangement position of the frame member 70 can be determined with high accuracy.
[Cavity]
In the center of the guide material A, there is a rectangular cavity 50 covered with the parallel plate 10. The hollow portion 50 is filled with customer soil after the completion of the frame.

<5> Formation of a through hole A through hole can be formed in each member constituting the guide material A (not shown).
By providing the through-hole, the green planted root penetrates the through-hole, so that the stability of the legal frame can be improved.
Further, when a biodegradable material is used for the guide material A, the surface area of the guide material A increases, which contributes to the promotion of biodegradability.
In addition, when a through-hole is provided, there is a concern about a decrease in strength. Therefore, it is also preferable to omit the through-hole in a portion of the guide material A that is easy for an operator to put on.
For example, the aspect which provides a through-hole in the parallel plate 10 except the location which forms the corner part 30 located in the shoulder side after installation in a grounding surface among the four corner parts 30 of the guide material A. Can be considered.

<6> Other Shape Examples The guide material A according to the present invention has any shape as long as it has at least an area for storing the end portion of the guide material (corresponding to the “accommodating space”). May be. In addition, it is more preferable if it has the area | region (equivalent to the said "corner corner 30") for accommodating the edge part of the scale material 60 mentioned later.
For example, even if the four side walls having an L shape are connected to each other with separate members in a state of being separated from each other, the configuration including the entrance corner and the accommodation space can be provided.
FIG. 2 shows another example of the shape of the guide material according to the present invention.
The guide material according to FIG. 2 integrates four side walls 20 having an L-shape with a bottom plate, forms a corner portion 30 at a bent portion of the side wall 20, and accommodates space at a separation portion between adjacent side walls. The aspect which comprises 40 is exhibited.

Next, the procedure of the method for constructing a legal framework according to the present invention will be described with reference to FIGS. 3A to 3F.
In addition, as long as there is no contradiction in work, each process can be changed in order or performed in parallel.

<1> Arrangement of scale material (FIG. 3A)
First, the scale material 60 is arranged inside the virtual region B where the arrangement of the method frame material 70 is planned from one side edge Y on the method edge X side.
The scale material 60 according to the present embodiment is configured by a cross-shaped member having a shape corresponding to a diagonal line of the virtual region B having a rhombus shape.

<2> Arrangement of guide material and frame material (FIG. 3B)
Next, the guide material A is arranged based on the scale material 60.
In FIG. 3B, the guide material described in the first embodiment is used as the guide material A.
First, the guide material A is arranged so that the open side end portion of the scale material 60 abuts on the corner 30 of the guide material A. At this time, the angle of the corner 30 is set to a position where the scale material 60 bisects the angle.
Next, the frame material 70 is arranged on the basis of the arranged guide material A.
At this time, if it arrange | positions so that the edge part of the legal frame material 70 may be accommodated in the accommodation space 40 in the guide material A, the legal frame material 70 will be installed in the natural correct position.
In this manner, a method frame C is formed in which the method frame material 70 is installed in a diamond shape.
In addition, after the installation of the legal frame material 70, the scale material 60 may be collected and used for the arrangement of the next legal frame material 70, or may be left in the legal frame C as it is.

<3> Construction of the first row of legal frameworks (FIGS. 3C and 3D)
In this way, by repeating the above steps <1> and <2> in the horizontal direction of the existing legal frame portion (FIG. 3C), the horizontal frame frame D (first-stage frame frame D1). Can be constructed (FIG. 3D).

<4> Construction of the second row of legal frameworks (FIG. 3E)
Next, the above steps <1> to <3> are repeated at the upper part of the first frame of legal frames D1 to construct a horizontal frame of frames (second legal frame). (FIG. 3E).
At this time, the worker carries out the work of transporting and installing the scale material 60, the guide material A, the legal frame material 70, and the like at the location where the second-stage legal frame row is constructed. In this case, the existing guide material A used in the first-stage frame can be used as the footrest A ′.

<5> Completion of Legal Frame The process of <4> above is further repeated up to the shoulder Z to complete the construction of the legal frame C (FIG. 3F).
After completing the frame C, a well-known operation such as a filling work of a land and a greening operation may be advanced to construct a slope.

The method for constructing a legal frame according to the present invention may include a step of separately providing a fixture for the installed guide material A and positioning it on the ground contact surface.
FIG. 4 shows a method of fixing the guide material A to the ground plane.
For example, a long bar 80 can be used as the fixture, and if the bar 80 is inserted into the corner located on the most shoulder side of the hollow part 50 of the guide A, the guide The material A is supported by the bar 80, and the guide material A can be prevented from shifting due to its own weight.
For example, when the target local board is hard, it is preferable to use a steel bar or the like that is not damaged by impact, and when the target local board is soft, a bar made of biodegradable plastic is preferably used.
These fixing operations may be performed immediately after each guide material A is arranged, or may be performed after the method frame C is partially or entirely formed.

  In addition, in the case where the greening of the target slope is made into a biodegradable greening, materials that do not biodegrade for a long time are removed after the vegetation has settled and the slope has stabilized.

The method for constructing a legal frame according to the present invention may further include a step of temporarily providing an arrangement reference line 90 in order to arrange the legal frame material 70 with high accuracy.
The arrangement reference line 90 can utilize the bar 80 described in the third embodiment.
In FIG. 5, after arranging the guide material A and the frame material 70 to some extent in the vertical and horizontal directions of the ground plane, an arrangement reference line 90 is used to confirm whether the installation position of the frame material 70 is correct. The state which has been provided is shown.
The arrangement reference line 90 is formed by a rope 91 that is connected from the tip of the rod 80 where the guide member A is positioned to the tip of the other rod 80.
If the rope 91 is connected so as to be parallel to the arrangement direction of the frame member 70 (directions of the sides constituting the frame C), the frame member 70 is correct with reference to the arrangement reference line 90. It can be easily confirmed whether or not it is arranged at the position.

In the method for constructing a legal frame according to the present invention, the configuration is not limited to a so-called “valley stack” in which the legal frame members 70 are continuous in a diamond shape.
For example, the guide material according to the second embodiment can be used as it is, as shown in FIG. 6, even if the method frame material 70 has a continuous configuration (so-called “clothing”) in a square shape.

  Further, as shown in FIG. 7, the shape of the normal frame C is not limited to a square shape or a rhombus shape, and the present invention can be applied to a rectangle (FIG. 7A), a triangle (FIG. 7B), or other polygons. Can be applied. At this time, the shape of the guide material A may be designed so as to correspond to the connecting portion of the normal frame material 70.
