DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a plant mixed with plant seeds.
The present invention relates to a slope vegetation method in which a green base material is sprayed on the outermost surface of the slope to prosper the plants early.

[0002]

BACKGROUND OF THE INVENTION new roads and reclamation areas, but will be slope and slope is convenience inevitably the formation of the construction work, and for this law surface or the like do not grow the plant at an early stage, rain As a result, soil on the slope is washed away (runs off), so that the shape of the slope itself cannot be maintained. In particular,
On the slope, if the soil and the like are left as they are, the natural environment such as the mountain surface is significantly impaired, the aesthetic appearance is deteriorated, and a depressed impression is given to a person.

[0003] For this reason, conventionally, a spraying method has been adopted in which plant seeds are sprayed onto a newly-formed or bare slope to promote early growth of the plants. In this conventional spraying method, the plant seeds are sprayed on a slope together with a fertilizer and a soil improving material, so as to achieve a short-term protection of a wide area of the slope and an early germination / growth of the plant seeds.

However, in this conventional spraying method, plant seeds, fertilizers and the like (hereinafter simply referred to as plant base materials) are mixed in a large amount of water, and the plant base materials and the like are sent by a pump and sprayed on the slope. Therefore, there is no problem as long as the slope has a gentle slope and good water absorbability. However, if the slope is a steep slope, or if the rock has a very exposed property with very poor water absorption, plant seeds etc. sprayed on the angled slope are treated with a large amount of water. It will flow down the surface.

[0005] In such a construction, even if the plant seeds 31 do not flow down, even if a large amount of rain falls after the construction, the vegetation base material 30 is not allowed to flow due to rainwater or the like. It is quite possible that they will run away.

[0006] The vegetation base material 3 at the time of construction as described above
A flow of 0 not only makes the construction itself difficult, but also requires a large amount of materials, which increases construction costs.

Also, if the vegetation base material 30 flows out after construction, it is natural that vegetation cannot be surely performed on the intended slope, and the construction site is inconvenient for remote traffic. In some cases, re-construction can be very costly.

The inventor of the present invention has made various studies to prevent the vegetation base material 30 from flowing down during construction and to prevent runoff after the construction, and as a result, the present invention has been completed.

[0009]

[SUMMARY OF THE INVENTION The present invention has been made in view of the above actual information <br/>, challenges to be its resolution,
First of all, it is to prevent the vegetation base material from flowing down at the time of construction, and to prevent runoff after the construction. Secondly, there is the prevention of rotation during and after the installation of the slope anchor.

[0010] Then, it is an First object of the invention according to claim 1, the slope face anchors 20 seen write out number to staggered hook shape, arranged in a dispersed state on the slopes Accordingly, it is possible to provide a slope vegetation method by relatively simple means, which can prevent the vegetation base material 30 from flowing down at the time of spraying construction and can surely prevent runoff even after construction. . In addition, the rotation of the anchor shaft is completely prevented during and after the driving.

The second object of the invention according to claim 2 achieves the same object as in claim 1 and further improves the object.
First, a long fiber 32 is mixed in the vegetation base 30 in advance.
In addition, the long fibers 32
An object of the present invention is to provide a slope vegetation method that can more reliably improve the fixation of the vegetation base material 30 to the slope by forming a large number of trapping recesses .

[0012]

Means for Solving the Problems In order to solve the above problems, means according to the first aspect of the present invention will be described with reference numerals used in the embodiments. A vegetation base material 30 in which sand, a binder, and the like are mixed in addition to the soil improvement material and fertilizer for spraying so that the first layer is formed on the surface layer of the slope 10, and directly on the surface layer of the slope 10. Slope vegetation method for vegetation on a slope 10
The upper side of the anchor shaft 21 has a slat 22 extending in a direction orthogonal to the anchor shaft 21, and the slope anchors 20 having the wings 23 are arranged in a zigzag manner below the lower part. implantation number, after <br/> allowed is formed in a dispersed state a number of weir Ru good the blade plate 22 of the slope anchors 20 on the slope, mixed plant seeds 31 in the vegetation base material 30 An object is sprayed onto the surface of the first base layer on the slope 10 located between the slope anchors 20 in a state where the upper end of the slat 22 is hidden so that the second layer of the vegetation base material 30 is formed. Slope vegetation method characterized by the fact that

That is, in the slope vegetation method of the present invention, a plurality of slope anchors 20 are staggered on the slope 10.
The vegetation base material 30 which does not mix plant seeds on the slope anchor 20
By spraying, the first layer of vegetation base material 30 sprayed on the slope anchor 20 is prevented from flowing down by the anchor shaft 21 of each slope anchor 20. Thereby, after the construction, the above-mentioned
The first vegetation base material 30 can be stabilized even during construction .

Further, the means adopted by the invention according to claim 2 is that, when the above-mentioned construction method is carried out, long fibers 32 are mixed in advance in the vegetation base material 30 to be sprayed on the slope 10. At the same time , one
Recessed recesses for long fibers 32 on the surface of the slats
Are formed in large numbers .

[0015]

The operation of the slope vegetation method according to the first aspect of the present invention will be described. First, a large number of slope anchors 2 are directly provided on the surface layer of the slope 10 which is bare.
However, since the bare ground, which is the ground, is softer than the concrete retaining wall, the wings 23 formed below the anchor shaft serve as a rotation preventing guide at the time of insertion. Are arranged in an orderly zigzag pattern as shown in FIG. In addition, each slope anchor 2
Constitute 0 has blades 22 which are integral to the anchor shaft 21, while being disposed as extending in the lateral direction, that the horizontal direction, the end portion of the front row and the back row of the slope anchors 20 have each other differences It is driven in such a way that it becomes a staggered shape . Thereby, the slope 1
In the surface layer of No. 0, the sprayed vegetation base material 30 is prevented from flowing down in the vertical direction and falling off. By performing the above construction, as shown in FIG.
Above, a large number of small weirs formed by the blades 22 of each of the slope anchors 20 are arranged in a staggered manner.

Then, each of the above-described slope anchors 2
After the vegetation base material 30 including the plant seeds 31 is blown onto the slope 10 located between the slope anchors 20, the vegetation base material 30 that has been sprayed is blown. When trying to flow down the slope 10, FIG.
As shown by the solid arrow in the middle, the blades 22 constituting the weir are securely dammed. Therefore, when the vegetation base material 30 is sprayed, the vegetation base material 30 does not flow down the slope 10 in a large amount, so that it is not necessary to prepare a large amount of the vegetation base material 30. In addition, since each vegetation base material 30 is blocked by the slats 22 of each of the slope anchors 20 during spraying, the vegetation base material 30 is exposed to a larger amount of water than in the conventional spraying method.
Can be mixed, whereby the operation of the pump becomes more reliable and stable.

[0017] In the slope vegetation method according to the invention of claim 2, for keeping the continuous fiber 32 is mixed because Ji pre respect to the vegetation base material 30, slope face 1 with the plant raw base material 30
The long fibers 32 sprayed on the zeros are entangled with the respective slope anchors 20 that have already been driven into the slope 10.

As shown in FIG. 1, the long fibers 32 entangled with each of the slope anchors 20 are further entangled with a part of the vegetation base material 30. As a result, the vegetation base material 30 is attached to the slope surface. 10 will be fixed. That is, the vegetation base material 30 is fixed to the slope 10 at the time of the spraying construction through the long fibers 32, so that the vegetation base material 30 is reliably prevented from flowing down.

On the other hand, when the vegetation base material 30 is sprayed by the pump, the blast plate 2
2 to change the angle, or the vegetation base material 30
The hole for transporting the slats 22 contacts the slats 22
2 may be changed.

However, for such a force,
This can be dealt with by inserting the lower surface of the slat 22 directly onto the slope 10 to make it difficult to rotate, or by firmly driving the anchor shaft 21 of the slope anchor 20 into the slope 10. Further, if necessary, as illustrated in the following example of the slope anchor 20, a lower portion of the anchor shaft 21 (a portion driven into the slope 10)
Since the wing portion 23 for preventing the rotation of the anchor shaft 21 is provided integrally, the rotation of the blade plate 22 is prevented.

Also, the slope 1 after the above construction is completed
0, the vegetation base material 30 is attached to each slope anchor 2
The long fiber trapping recess formed on the surface of the vane plate 22
(Not shown) entangles long fibers, and vegetation of these long fibers
Reinforcement prevention effect in the base material 30 and entanglement between fibers
Since the vegetation base material 30 is held firmly by the reinforcing effect, etc. , even if it rains and the like, a large amount of water is again contained in the vegetation base material 30 and water flows on the surface of the vegetation base material 30, The material 30 does not flow.

In particular, when the construction method of the second aspect is adopted, the vegetation base material 30 is connected to each other like the earth wall of a house on the slope 10 by the long fibers 32 therein. such Rutotomoni, the long fibers of the blade plate 22
Because and Tsu by that entangled to capture recess formed on the surface, erosion of the vegetation base material 30 will be fully prevented.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the invention according to each claim will be described with reference to the embodiments shown in the drawings. The invention according to claim 1 is substantially included in the invention according to claim 2. ,
The following description will be made mainly on the slope vegetation method according to claim 2.

First, in the present invention, as shown in FIG. 1, a large number of slope anchors 20 are driven onto the slope 10, and the arrangement of these slope anchors 20 is as shown in FIG. It is important to make a zigzag pattern. Because by arranging, as shown in FIG. 2, slopes 10
The vegetation base material 30 that is going to flow down with the water that falls in the vertical direction of
This is because it can be stopped at all weirs . Of course, the slope anchors 20, vane plate 22 which is integral to the anchor shank 21 be implanted arranged so as to be positioned in a horizontal state, slope vertical vegetation base material 30
This is most effective in preventing flow in the direction . Therefore,
It is preferable that the arrangement density of each slope anchor 20 is at least 1 / m ² .

Each of the slope anchors 20 used here
For example, as shown in FIGS. 3 to 5 , a portion of the anchor shaft 21 that is to be driven into the slope 10 (a portion exposed on the surface of the slope 10) is orthogonal to the anchor shaft 21. The blade plate 22 extending laterally is integrated.

The integration of the blade plate 22 with the anchor shaft 21 may be achieved by forming the entire slope anchor 20 by so-called integral molding, but may also be performed by bonding or welding. In the case of bonding or welding, as shown in FIG. 4 , a concave groove into which the anchor shaft 21 can be inserted is formed in the center of the blade plate 22, and the concave groove allows the blade plate 22 to be fixed to the anchor shaft 21. It is preferable to increase the contact area.

The blade plate 22 of the slope anchor 20 shown in each figure is formed as a simple plate, but this blade plate 22 is for damping the vegetation base material 30 which is going to flow down or run off. Therefore, in order to be able to reliably perform the damming, even if it is configured as a curved one that is convex below the slope 10 or a whole that has a large number of trapped recesses in a wavy shape, it may be implemented. Good.

When the arrangement and fixing of the slope anchors 20 are completed, the vegetation base material 30 is sprayed on the slope 10 located between them. In this embodiment, the spraying is performed twice. I made it. The first time, ie, the plant seeds 3 in the vegetation base material 30 to be sprayed directly on the slope 10
1, so that the plant seeds 31 are mixed into the vegetation base material 30 formed by the second spraying, that is, the vegetation base material 30 serving as the topsoil of the slope 10 which is the second layer of the vegetation base material 30. , A total of two sprays. The reason is that when the thickness of the vegetation base material 30 is large, plant seeds 31 for vegetation may be buried deep in the soil, and such plant seeds 31 have a low germination rate,
In other words, if the vegetation base material 30 has a thickness that does not hinder the germination of the plant seeds 31, the vegetation base material 30 may not be formed on the slope.
With the plant seeds 31 included from the beginning, the spraying operation can be completed only once.

When the spraying was divided into two times, the first vegetation base material 30 was configured to include sand, soil improvement material, fertilizer, joining material and the like. In this case, as the sand, soil or mountain sand at the construction site is used,
As the bonding agent, cement, lime or synthetic resin is used. Park compost or perlite is used as a soil improving material, and for example, superphosphate lime is used as a fertilizer.

More specifically, a fertilizer is added to a mixture of cement, water, and sand at a weight ratio of 1: 2: 26 to obtain a vegetation base material 30, which is used as a blade plate 2.
2 is sprayed to the extent that it hides.

The second layer of vegetation base material 30 comprises a plant seed 31 of a type suitable for vegetation of the slope 10 to those described above.
However, as the plant seed 31, Kentucky, weeping grass, or the like is selected. The thickness of the vegetation base material 30 mixed with the plant seeds 31 for forming the second layer after construction is equal to the thickness of the first layer vegetation base material 30 not including the plant seeds 31 formed thereunder. Is about 12 cm, it is preferably about 3 to 7 cm.

Of course, long fibers 32 are previously mixed in the above-mentioned two vegetation base materials 30 as shown in FIG. 1 , and the long fibers 32 are, for example, those of peat moss. the plant fibers or continuous filaments shape, such as
Cotton or chemical fiber

[0033]

As described above in detail, in the invention according to the first aspect, as exemplified in the above embodiment, "in addition to soil improvement material and fertilizer for growing and growing plants, sand and bonding A slope vegetation method for spraying a vegetation base material 30 mixed with an agent or the like so that a first layer is formed on the surface layer of the slope 10, and performing vegetation directly on the surface layer of the slope 10; Slope 1
On the upper side of the anchor shaft 21, a slat 22 extending in a direction perpendicular to the anchor shaft 21 is provided, and a sloping anchor 20 having a wing portion 23 is arranged in a zigzag pattern below the wing plate 22. implantation yo number, after the formation <br/> in a dispersed state a number of weir Ru good the blade plate 22 of the slope anchors 20 on the slope, mixed plant seeds 31 in the vegetation base material 30 An object is sprayed onto the surface of the first base layer on the slope 10 located between the slope anchors 20 in a state where the upper end of the slat 22 is hidden so that the second layer of the vegetation base material 30 is formed. What I did is that. This makes it possible to provide a slope vegetation method by simple means, which can prevent the vegetation base material from flowing down during spraying construction and can surely prevent runoff even after construction.

According to the slope vegetation method according to the second aspect, the plant seeds 31 and the long fibers 32 are mixed in the vegetation base material 30 in advance, and the blades of the slope anchor 20 are provided. Since many trapping recesses for long fibers 32 are formed on the surface of the plate 22, the long fibers 32 are entangled with the slats 22 of each of the slope anchors 20, and
And the plant seeds 31 and the like can be more reliably fixed to the slope 10, and it is possible to reliably prevent the vegetation base material 30 and the plant seeds 31 from flowing down and flowing out during or after construction.
