Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a construction method for vegetation and a vegetation member used therefor.

[0002]

2. Description of the Related Art In recent years, there has been a strong demand for greening of slopes.
Conventionally, various greening measures have been taken. For example, it has been done that a greening net is laid on the slope and the seeds are sprayed there, or a vegetation bag containing seeds and fertilizers is moored in advance on the net.

[0003]

However, in the case of using such a greening net, if the slope is bare ground, it was effective as a soil retaining material. In areas where vegetation is complete and overgrown to an unnecessarily long length without adequate care, it is difficult to lay the net stably, or the surrounding weeds may cause sunlight. There was a problem that even if germination was carried out, the subsequent growth would be hindered.

The present invention has been devised and devised in view of the above-mentioned conventional problems, and its object is to obtain desired vegetation such as woody plants at a place where a certain vegetation is growing. It is to provide a construction method suitable for mixing the above and a vegetation member used for the construction method.

[0005]

According to the invention of claim 1 for achieving the above object, a desired vegetation such as woody plants is pressured from other vegetation at a part of the target surface of the vegetation. In order to grow so as not to grow, vegetation members for securing these growth regions are scatteredly arranged.

According to the second aspect of the present invention, a bag body containing the vegetation material is provided inside, and the surface of the bag body facing the target surface of vegetation is poorer in weather resistance than other surfaces. It is made of a material and used as a penetration surface of the root, and around this penetration surface, a holding member for arranging a shape that can substantially adhere to the vegetation target surface is arranged. It is what

Furthermore, the invention of claim 3 is characterized in that, in the invention of claim 2, the bag body is provided with a water retaining material.

[0008]

According to the invention of claim 1, when another kind of vegetation is to be grown in a place where a certain kind of vegetation grows or will grow in the future, a vegetation member is attached to the planned growth area of this different kind of vegetation. It will be installed locally. Since each vegetation member is arranged with such a length or size that it is not pressed by the surrounding vegetation, that is, because its growth area can be secured, desired vegetation can be realized.

According to the second aspect of the present invention, since the holding member is provided around the penetrating surface, the penetrating surface is held in a substantially planar shape along the vegetation target surface. It can be installed stably.

Further, according to the third aspect of the invention, since the moisture inside the bag is retained by the water retaining material, corrosion is promoted at the bottom portion formed of a material having poor weather resistance. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
If it demonstrates based on FIG. 5, FIG. 1 shows the whole vegetation member which concerns on this embodiment, and is comprised mainly of the bag body 1 as shown in the same figure. The bag 1 has a vertical cross-section that is substantially a semi-cylindrical shape with the vegetation material S enclosed therein. Then, when the work is applied to the slope N, the surface facing the slope N becomes the ground contact portion 2, and the other portion forms the surface portion 3.

A frame line 4 for retaining the shape of the grounding portion 2 is formed in a portion of the bag body 1 that forms the peripheral edge of the grounding portion 2.
(The holding member of the present invention) is embedded. The frame wire 4 is formed by bending a metal wire having a diameter of about 3 mm into a rectangular shape as a whole, and each edge of the surface portion 3 and the grounding portion 2 is tied to the frame wire 4. There is.

The surface portion 3 is formed by knitting filaments made of a material having excellent weather resistance (for example, synthetic fibers such as polyethylene and polyester) into a net shape by plain weave, and the size of the stitches hinders germination. It is necessary that the vegetation material S inside does not come out easily and does not easily spill out. Further, the surface portion 3 is bound by crimping each edge of the surface portion 3 to the frame line 4 at appropriate intervals using a retaining ring 5 or the like.
In the state before being charged, only the portion corresponding to one short piece portion of the frame line 4 is in an unbonded state and is open. Further, the surface portion 3 is sufficiently larger than the area surrounded by the frame line 4 so that it is bound to the frame line 4 in a relaxed manner, whereby a necessary amount of the vegetation material S is enclosed inside. When you do, you will be in a kamaboko shape and become nervous.

Contrary to the surface portion 3, the grounding portion 2 is made of a material having poor weather resistance (for example, hemp, cotton, rayon, etc.) and is knitted in a net shape so that the vegetation material S inside can be easily formed. The knitting of the degree that does not spill is used for. The grounding portion 2 is formed to a size slightly larger than the portion surrounded by the frame line 4, and is fixed to the frame line 4 together with the surface portion 3 in the above-described manner. In this way, unlike the surface portion 3, the grounding portion 2 is bound to the frame line 4 in a substantially tensioned state, and therefore, even after the vegetation material S is enclosed, it keeps a substantially flat shape with respect to the slope N. It enables stable installation.

The vegetation material S enclosed in the bag 1 is
The slope N is a construction target, and various adjustments are made according to the required greening conditions.
General soil, seeds of flowers and woods, slow-acting and fast-acting fertilizers are used. Further, in the present embodiment, in addition to the vegetation material S described above, a powder water retention agent is mixed. Such a water retention agent plays a role of preventing the inside of the vegetation material S from drying and promoting the corrosion of the ground contact portion 2. As the water-retaining means, in addition to using such a powdery water-retaining agent, it is also possible to use one in which a non-woven fabric having water-retaining property (which allows free penetration of roots) is layered on the grounding portion 2. Conceivable.

Next, an example of construction for greening the slope N by the above vegetation material will be described. Here, you already have a Toshiba G (of course,
An example of construction in the case of growing flowers or woody plants on the slope N where other vegetation may be present is shown.

First, prior to construction, the above-mentioned vegetation material S is filled into the inside of the bag body 1 to a full state, and then the opening portion is closed. An appropriate number of bags 1 thus sealed are prepared and scattered at the planned vegetation site of woods with respect to the slope N. For example, as shown in FIG. 4, they are arranged in a staggered manner, and each longitudinal direction is along the inclination direction of the slope N. Then, a plurality of L-shaped anchors 6 are hooked on the frame line 4 and driven into the slope N while fixing the whole. The reason why each bag body 1 is formed vertically long and fixed along the slope of the slope N is as follows. That is, the grass T growing on the slope N generally extends downward along the slope of the slope N.
This is because, if is fixed laterally, the entire bag body 1 is buried in the lawn G when the height of the lawn G is high, and the growth of plants is inhibited.

Although it is not easy to stably install the bag 1 on the slope N where the grass G is prosperous, in the present embodiment, the bag 1 is stably installed as follows. Is now possible. That is, in the case where the bag body 1 has a general bag shape (a shape in which the peripheral edges of two cloth bodies are sewn together), when the vegetation material is fully enclosed inside, the vertical cross section approaches a circular shape. Then, the contact area with respect to the slope N becomes small, and the installation can be performed only in an unstable posture. On the other hand, in the present embodiment, even if the vegetation material S is fully enclosed by the frame line 4, the planar shape of the ground contact portion 2 is maintained, so that a large ground contact area with respect to the slope N can be secured. Therefore, the installation posture can be stabilized.

Now, as described above, each vegetation material has a slope N.
, The seeds inside the bag 1 germinate through the stitches of the surface portion 3 after a predetermined number of days. On the other hand, since the ground contacting portion 2 of the bag 1 is in contact with the soil surface of the slope N, the ground contacting portion 2 is gradually corroded due to the influence of soil moisture, etc., and a part of it deteriorates and breaks. In particular, in this embodiment, since the following two points are devised so that the corrosion is further promoted, the root can be easily penetrated into the slope N soil.

The first point is that since the water retaining agent is mixed in the vegetation material S, the vicinity of the ground contact portion 2 can be maintained at a relatively high humidity.

The second point is that since the grounding portion 2 is held in a planar shape, the entire grounding portion 2 is brought into close contact with the slope N so that it can always come into contact with soil moisture. In the case of such a normal bag shape, the cross-sectional shape becomes substantially circular and the contact area decreases, and conversely, the area in contact with the surface air increases and it becomes easy to dry.

That is, the ground contact portion 2 is necessary for preventing the vegetation material from falling down before being installed on the slope N, but is unnecessary from the viewpoint of rooting after installation. In the present embodiment, this point can be achieved by using a material that easily corrodes, such as hemp, for the ground contact portion.

From the above, in the present embodiment, the grounding portion 2
Corrosion is promoted and the roots can grow freely,
Therefore, good growth of the plant is realized.

The present invention can be variously modified.
The following modifications are also included in the technical scope of the present invention.

The frame line 4 may be formed in a lattice shape in addition to the one forming the peripheral edge of the ground portion 2, and may be formed three-dimensionally if necessary.

The grounding portion 2 does not necessarily have to be formed over the entire area of the bag body 1, but may be set in a region of a suitable size.

The bag 1 does not have to be rectangular, but may be circular, elliptical, or any other polygonal shape, as long as the entire surface of the bag 1 is not covered by the surrounding grass G.

In the present embodiment, an example of construction on the slope N is shown, but it is of course applicable to greening on a flat ground.
