<Spraying process of planting soil>
A soil layer 12 is formed on the slope 2 so that the wire mesh 3 is buried as shown in FIG. 7 by spraying the soil for planting on the wire mesh 3 and the reinforcing frame 1 for planting with a mortar gun. At the same time, a planting soil base 13 raised from the soil layer 12 is formed so that the planting reinforcement frame 1 is buried.
[0066]
When spraying the soil for planting, place the soil tank on a flat ground below the slope 2 and extend the hose to the slope 2 to pump the soil for planting the soil tank with the mortar gun. And it will spray on the reinforcement frame 1 for planting.
[0067]
As the planting soil, it is preferable to use a seed and artificial soil kneaded with water. As seeds to be used, turf and other grasses are suitable, but are appropriately selected according to the climate of the land. As artificial soil, a mixture of sawdust and pulverized potato, fertilizer and glue can be used.
[0068]
<Planting process>
A hole reaching the inside of the planting reinforcement frame 1 is made in the planting soil base 13 and a seedling 14 is planted. This planting is performed after the grass has grown by the spraying of the previous planting soil and the soil tank 12 and the planting soil base 13 have become stable (for example, one year later). The seedling 14 may be planted so that its trunk is in the vertical direction, but is planted so as to be substantially perpendicular to the slope 2 as shown in FIG.
[0069]
Therefore, in the case of this example, since the soil for planting is sprayed with a mortar gun to form the soil layer 12 and the soil base 13 for planting, the filling of the soil into the reinforcing frame 1 for planting, It is not necessary to perform the outside arrangement in a separate process, the formation of the soil layer 12 and the formation of the planting soil base 13 can be performed simultaneously, and it is not necessary to separately transport the planting soil, Construction can be performed easily and quickly. Moreover, since the soil for planting can also be piled up outside the reinforcement frame 1 for planting, even if the reinforcement frame 1 for planting itself is not so large, the soil base 13 for planting can be enlarged, It is advantageous for planting.
[0070]
Thus, in the planting soil base 13, the planting soil inside the planting reinforcement frame 1 and the outer planting soil are joined together through the through holes 4 c and 5 c of the surrounding surfaces 4 and 5. In addition, rainwater and wind can prevent the outside planting soil from being washed away or scattered. In addition, since the enclosure surfaces 4 and 5 are inclined and rise up so that the inside becomes narrower as they go upward, the planting soil base 13 is prevented from falling off the planting soil that is inclined and raised. It is advantageous.
[0071]
Rain water flowing down the slope 2 from above and water flowing down from the ground is received by the mountain side surface of the planting reinforcement frame 1 and enters the planting reinforcement frame 1 from the opening surface 6. Even if the water that has entered inside flows down to the two sides of the valley side, it flows down through the surrounding surfaces 4 and 5, so that the water spreads over the entire soil base for planting, and the planting at that time The surrounding surfaces 4 and 5 prevent the soil from being washed away.
[0072]
As the seedling 14 grows, the roots protrude from the through holes 4c and 5c of the surrounding surfaces 4 and 5, and after several years, the roots may become thicker than the through holes 4c and 5c. Sometimes, the planting reinforcement frame 1 itself is corroded and does not hinder root growth. Therefore, the slope 2 can be greened by the growth of the seedling 14, and the soil layer 12 can be greened by germination growth of grass seeds.
[0073]
-Example 2-
This example is shown in FIG. 8, and the reinforcement frame 21 for planting is formed in a quadrangular pyramid shape.
[0074]
That is, the planting reinforcement frame 21 is formed in a quadrangular pyramid shape by a combination of three trapezoidal enclosure surfaces 22 and one trapezoidal opening surface 23 arranged on the slope side of the slope. The enclosure surface 22 is formed of a trapezoidal frame 22a in the form of an insulator in which a large number of vertical wires 22b connecting the upper side and the lower side or the oblique side and the lower side are arranged in parallel at predetermined intervals. A space between the wires 22b and 22b is formed in the through hole 22c. The opening surface 23 is formed by a trapezoidal frame member 23a. The frame member 23a includes a central hook member 24 projecting downward from the center of each of the upper side and the lower side, and oblique sides on both sides thereof. Both-end hook members 25, 25 projecting downward from the lower side are provided. Hooks 26 and 27 having hooking portions 26a and 27a protruding to the valley side are formed at the lower ends of these hook members 24 and 25. The upper and lower surfaces of the planting reinforcement frame 21 are open.
[0075]
The method of using the reinforcing frame 21 for planting is the same as that of the first embodiment, and the effect of taking in natural water such as rainwater flowing down from the mountain side and the effect of the through holes 22c are slightly different from those of the first embodiment. In the example, basically, the same effect as in the first embodiment can be obtained.
[0076]
-Example 3-
This example is shown in FIG. 9 and is characterized in that the reinforcing frame 31 for planting is formed in a truncated cone shape.
[0077]
That is, the reinforcing frame 31 for planting connects the three large, medium, and small circular frames 32, 33, and 34 by a large number of vertical wires 35 arranged in the circumferential direction at regular intervals, and the vertical wires 35 By connecting with four hook wire rods 36 arranged in parallel in the circumferential direction at intervals wider than the interval, a truncated cone shape is formed. A gap between four adjacent hook wires 36 forms an opening surface 37 disposed on the peak side of the slope, and a portion where a large number of vertical wires 35 are disposed forms a surrounding surface 38.
[0078]
A gap between adjacent vertical wires 35 on the surrounding surface 38 forms a through hole 39, and the four hook wires 36 have hooks 40 whose lower portions protrude downward from the large-diameter circular frame 32. The latching part 40a which protruded to the trough side is provided in the lower end part. The upper and lower surfaces of the planting reinforcement frame 31 are open.
[0079]
In the case of the reinforcing frame 31 for planting, it is considered that the intake of natural water is slightly lowered, but the same effect as in Example 2 is obtained.
[0080]
Example 4
This example is shown in FIG. 10 and is characterized in that the reinforcing frame 41 for planting is formed in a truncated cone shape and a metal lath is used for the enclosing surface.
[0081]
That is, the reinforcement frame 41 for planting connects the large and small circular frames 42 and 43 by three hook wire rods 44 arranged at equal intervals, and is attached to other surfaces except the surface on the slope side. A metal lath 45 is stretched so that the mountain side surface is formed on the opening surface 46, and a portion where the metal lath 45 is stretched is formed on the surrounding surface 47. Further, the mesh of the metal lath 45 forms a through hole 48. Further, the hook wire 44 protrudes downward from the large-diameter circular frame 42 to form an anchor 49, and the anchor 49 is driven into a slope. Further, the upper and lower surfaces of the planting reinforcement frame 41 are open.
[0082]
In the case of the reinforcing frame 41 for planting, it is considered that the intake of natural water is slightly lowered, but the same effect as in Example 1 is obtained.
[0083]
-Example 5
This example is shown in FIG. 11 and is characterized by the shape of the reinforcing frame 51 for planting.
[0084]
That is, as shown in FIG. 11, the planting reinforcement frame 51 includes a mountain-side opening 52 formed by a trapezoidal frame 52a, and a trapezoidal frame that is narrower and lower in height than the frame 52a. 53a between the side edge of the trough-side opening surface 52 and the side edge of the trough-side surrounding surface 53, respectively. A rectangular frustum having left and right laterally enclosing surfaces 54 and 54 formed by a net member in which a metal lath 54b is stretched on a rectangular frame 54a. The valley-side enclosure surface 53 is formed to be narrow and low in height. Moreover, the upper and lower surfaces of the reinforcing frame 51 for planting are open.
[0085]
−Reference example−
This example is shown in FIGS. 12 and 13, and is characterized by the enclosing surface of the reinforcing frame 61 for planting.
[0086]
That is, the reinforcing frame 61 for planting has a planar shape formed in a triangular shape as shown in FIG. 12, but each side is arranged in parallel at intervals in the longitudinal direction as shown in FIG. 13. The triangular frame 62 is formed in a triangular cylindrical shape formed by connecting the apexes of the triangular frame 62 by three wire members 63 extending in the longitudinal direction, and the three sides of the triangular frame 62 are adjacent to each other. An enclosure surface 65, which is 64, is formed. On one side arranged on the mountain side of the slope, hooks 66 projecting downward to be hooked on the slope metal mesh are provided at three places at the center and both ends. The upper and lower surfaces of the planting reinforcement frame 61 are open.
[0087]
Therefore, in the case of this example, since the surrounding surface 65 is formed by the triangular cylinder, the holding power of the planting soil is increased, which is advantageous for preventing the loss due to rainwater or the like.
[0088]
In addition, about the one side which should be arrange | positioned at the mountain side, you may make it open by providing the triangular frame 62 only in three places of a center and both ends.
[0089]
Further, for each of the sides, an inverted V-shaped wire 67 shown in FIG. 14 may be used instead of the triangular frame 62. Further, the number of hooks 66 may be increased for one side arranged on the mountain side.
[0090]
−Example 6−
This example is shown in FIGS. 15 and 16 and is an example in which the soil cover 70 is provided in the first embodiment.
[0091]
That is, as shown in FIG. 15, flexible metal fixing pins 71 projecting upward are provided at the lower ends of the three corners of the planting reinforcement frame 1. On the other hand, the soil cover 70 has a rectangular shape formed of a green felt material, and a pin hole 72 through which the fixing pin 71 of the planting reinforcement frame 1 passes is fixed to the planting reinforcement frame 1. Corresponding to the position of the pin 71, it is formed in three places. In addition, a cut is formed in the center of the soil cover 70 in an arc shape so that the planting hole 73 can be formed by raising the inner part of the cut.
[0092]
At the time of construction, as in Example 1, the wire mesh 3 is stretched on the slope 2, the planting reinforcement frame 1 is fixed, and the planting soil is sprayed (formation of the planting soil base). When spraying the planting soil, as shown in FIG. 15, the spraying is performed with the fixing pin 71 of the planting reinforcement frame 1 protruding obliquely upward. This is to prevent the fixing pin 71 from being buried in the planting soil.
[0093]
Then, as shown in FIG. 16, the soil cover 70 is put on the soil base for planting while passing the fixing pin 71 of the planting reinforcement frame 1 through the pin hole 72 of the soil cover 70. Then, the soil cover 70 is securely fixed to the planting reinforcement frame 1 by bending the fixing pin 71 inward along the surrounding surfaces 4 and 5 of the planting reinforcement frame 1.
[0094]
Therefore, since the soil base for planting is covered by the soil cover 70 so that the space for growing grass is not formed, and the irradiation of sunlight is blocked, the grass growth is prevented. The For this reason, for example, even when a seedling is planted after six months or one year has elapsed, the planting can be easily performed without being obstructed by the grass.
[0095]
The seedlings are planted by opening a planting hole 73 in the center of the soil cover 70 and leave the soil cover 70 for a while after planting. As a result, the seedlings can grow without being hindered by weeds, which is advantageous for their establishment. The soil cover 70 may be removed after the energization.
[0096]
In the above embodiment, the soil cover 70 is cut in advance so that the planting hole 73 can be immediately formed at the time of planting. You may make it form a hole for planting.
