Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening mechanism and a greening method on a slope where mortar, concrete, etc. are sprayed, or on a slope where it is difficult to grow plants such as bedrock.

[0002]

2. Description of the Related Art A so-called thick-layer soil revegetation method in which sandy soil and a soil conditioner, cement, fertilizer and plant seeds are mixed by stirring and sprayed with a shotgun etc. It has been known.

By the way, in general, there are problems in growing plants on slopes such as a mortar spraying surface, which are difficult to grow, because of the effect of drying the vegetation base and vegetation due to rainwater flowing on the surface such as mortar surface. Sliding down of the base,
Lack of nutrients and water due to the inability of roots to enter the ground,
and so on.

[0006] Looking at the above-mentioned thick layer soil revegetation method from this point of view, this method generally has weak adhesion (adhesion) to the slope and shear strength. Sliding of the vegetation base due to pore water pressure and the roots of grown plants cannot grow at the joint surface with the slope, resulting in slippage due to being on the mat or water supply from the ground itself which is a difficult slope for plant growth. There is a problem on the stability of the vegetation base such as cracks in the soil itself caused by rapid drying in places where it cannot be expected at all, and it is not possible to adequately address the above problems (1) to (3).

Therefore, as a means for solving the above-mentioned problems (1) to (4), there is one disclosed in Japanese Patent Publication No. 62-11127. That is, in this greening method, a belt-shaped fiber synthetic mat is stretched in a contour line on the slope at appropriate intervals with a concrete nail. Next, anchor bolts are driven along the lower end of the belt-shaped fiber synthetic mat at appropriate intervals, and the heads of the anchor bolts are connected by a reinforcing bar. Further, the drainage pipes are inserted at appropriate intervals into the strip-shaped fiber synthetic mat at an angle such that the back surface water of the slope is guided to the outside. Next, the tip of the drainage pipe is exposed to the outside, and mortar is sprayed downward from the central portion of the strip-shaped fiber synthetic mat so as to cover the drainage pipe, the reinforcing bars and the anchor bolts to form a horizontal beam in contour lines. After that, a vegetation material is sprayed on the slope sectioned by the horizontal beam to form a vegetation base, thereby greening the slope surface.

[0006]

However, the above-mentioned conventional greening method seems to have solved the above-mentioned problems (1) to (4), but when examined in detail, the following drawbacks were found. is there. That is, the vegetation material sprayed on the slope is located on the upper surface of the belt-shaped fiber synthetic mat stretched directly so as to adhere to the slope,
Considering the runoff after spraying, the vegetation material cannot be sprayed so thickly, therefore the vegetation base consisting of the vegetation material sprayed on the slope does not have much water retention capacity, and the above-mentioned problems are Not completely resolved.

The vegetation base is not connected to the ground beneath the mortar surface, and therefore the roots of the plants emerging from the vegetation base are not rooted in the ground. That is, the above problems are still unsolved.

Further, in the above conventional greening method,
Mortar must be sprayed to cover the drainage pipes, rebars and anchor bolts to form a horizontal beam, and then vegetation material must be sprayed.
Not only is it necessary to repeat the work, but it also requires the installation of drainage pipes, making the construction extremely complicated, and the horizontal beams made of mortar are exposed even after the vegetation material has been sprayed onto the slopes, providing a good view. There is the inconvenience of not having it.

Therefore, as a solution to the above problems, the applicant of the present application dated August 24, 1991, made a hole in the mortar surface, attached a fiber synthetic mat, and installed the partition member in a contour line shape. Then, a patent application has been filed for a greening method in which a mesh-like body is stretched on the vegetation material and sprayed over the entire slope (Japanese Patent Application No. 3-237451). However, it takes a lot of time to stretch a plurality of fiber synthetic mats, and further, to install a plurality of partition members on the fiber synthetic mat, and it is not easy to construct and easy to install the mesh body, And it is difficult to do it quickly.

The present invention has been made in view of the above matters, and an object of the present invention is to provide a planting-difficulty slope greening mechanism capable of easily and quickly attaching a reticulated body, and To provide a greening method.

[0011]

In order to achieve the above-mentioned object, the planting-difficulty slope greening mechanism according to the present invention is provided so as to be open even in a natural ground at an appropriate interval on the slope. A plurality of holes, and a plurality of strip-shaped fiber synthetic mats provided so as to be fixed to the slope at appropriate intervals,
A plurality of tubular bodies that can be erected in a contour line and are attached in a ladder shape across these belt-shaped fiber synthetic mats at appropriate intervals via each body wall surface. It is composed of a net-like body which is stretched from above so as to cover the entire slope, thereby allowing the vegetation material to be sprayed over the slope.

From another point of view of the present invention, a plurality of strip-shaped fiber synthetic mats and a plurality of cylindrical bodies which are attached in a ladder shape across these strip-shaped fiber synthetic mats at appropriate intervals. It is possible to provide a slope fixing unit composed of, and a plurality of slope fixing units in which a fiber synthetic mat and a tubular body are integrated are provided on each slope so that each tubular bag stands up in a contour line. It can be fixed individually.

That is, according to the present invention, a plurality of holes are provided on the slopes at appropriate intervals so as to be open in the ground, and are fixed on the slopes at appropriate intervals. It is composed of a plurality of strip-shaped fiber synthetic mats and a plurality of cylindrical bodies that are attached in a ladder shape across the strip-shaped fiber synthetic mats at appropriate intervals via each body wall surface. A plurality of slope fixing units that are fixed to the slope so that the tubular body is erected in a contour line, and stretched from above these units so as to cover the entire slope,
It is possible to provide a greening mechanism for a plant growth difficult slope, which is composed of a net-like body capable of spraying vegetation material on the entire slope.

Furthermore, the present invention provides a greening method using each of the above greening mechanisms. That is, a plurality of holes are formed on the slope at appropriate intervals so as to open even in the ground, and then a plurality of tubular bodies are spread over a plurality of strip-shaped fiber synthetic mats having appropriate intervals. Girders are installed in a ladder shape with appropriate intervals so that they stand upright in a contour line through each body wall,
Then, a net-like body is stretched from the top of each of the tubular bodies so as to cover the entire slope, and thereafter, vegetation material is sprayed onto the entire slope from above the net-like body. Provide a greening method for slopes.

Further, the planting difficult slope greening method of the present invention is provided with a plurality of holes on the slope at appropriate intervals so as to open even in the ground, and then a plurality of cylindrical bodies. Each of the tubular bodies is a contour-line-shaped slope fixing unit formed by straddling a plurality of strip-shaped fiber synthetic mats having an appropriate interval and being attached in a ladder shape at an appropriate interval via each body wall surface. To stand upright, fix a plurality of slopes, then stretch a net over each of the tubular bodies so as to cover the entire slope, and then vegetation material over the nets. It consisted of spraying the entire slope.

[0016]

With the above construction, a plurality of tubular bodies are integrally attached to a plurality of belt-shaped fiber synthetic mats to form a slope fixing unit, and the slope fixing unit is formed on the slope as much as necessary. Since it is fixed, compared to the one in which the fiber synthetic mat and the partition member are separate, it is possible to hang and fix a plurality of tubular bodies integrally with the fiber synthetic mat from the upper part of the slope, and to attach the mesh body. It can be done easily and quickly.

Further, the net-like body is held by a tubular body that is erected in a contour line with respect to the slope, and the net-like body is floated from the slope. Therefore, the vegetation material can be sprayed thickly on the slope as much as the net is floated, and the water retention capacity of the vegetation base formed by the vegetation material is increased accordingly. And since a plurality of holes are provided on the slope at appropriate intervals so as to open even in the natural ground, water from the natural ground travels along the body wall surface of the tubular body, and through this hole Will be replenished. As a result, there is no fear of drying in the vegetation base.

Further, since a plurality of belt-shaped fiber synthetic mats are fixed to the slope at appropriate intervals, collection and drainage are smoothly performed, and the tubular body extends over the belt-shaped fiber synthetic mat. The vegetation base is firmly attached to the slope without slipping off because it is erected in a contour line through each trunk wall and a net is provided so as to cover the entire slope. .

Further, the roots of the plants in the vegetation base reach the ground through a plurality of holes formed in the slope, and the plants on the slope are also supplied with water and nutrients from the ground. In other words, since the vegetation base and the ground are integrated to grow plants on the slope, the slope is more surely greened.

[0020]

A plurality of strips having a width of about 10 to 20 cm, a length of about 20 to 30 m, a length of 20 to 30 m, and a thickness of about 1 to 2 cm on the mortar spraying surface 2 at appropriate intervals. The fiber synthetic mat 4 (for example, Stella sheet: trade name) 4 is attached and fixed by concrete nails (not shown). In this case, a plurality of tubular bodies 7 are straddled over a plurality of strip-shaped fiber synthetic mats 4 having appropriate intervals, and each body wall surface 7a
Attach them in a ladder shape at appropriate intervals so as to stand upright in a contour line through (see FIG. 4). That is, in FIG. 4, each fiber synthetic mat 4 has a mounting portion 4a for a plurality of tubular bodies 7, and a plurality of tubular bodies 7 are inserted and fixed in advance in the mounting portions 4a. A plurality of Us are spread in the vertical direction (direction of arrow X in FIGS. 3 and 4), which is the direction in which the mortar spraying surface 2 is inclined. At this time, in each slope fixing unit U, the cylindrical bodies 7, 7 arranged adjacent to each other in the longitudinal direction (direction of arrow X in FIG. 3) are preferably provided at intervals of 50 to 100 cm, Further, the fiber synthetic mats 4 and 4 arranged adjacent to each other in the lateral direction (the direction of the arrow Y in FIG. 3) are 200 to 300c.

Each of the tubular bodies 7 of the slope fixing unit U has a diameter of about 5 cm, and the tubular body 7 is composed of a plurality of meshes (mesh of 0.5 to 1.0 cm square) 6. A plurality of body wall surfaces 7a are formed, and as described above, the contours are formed at intervals of 50 to 100 cm (see FIGS. 3 and 5) so as to be substantially vertical to the mortar spraying surface 2, and the anchors are provided. Fix with bolts 8 (see FIGS. 1 and 2). In this case, as the tubular body, in addition to the hollow reticulated pipe as in the present embodiment, reticulated pipe 7 is filled with a water-retaining material such as vermiculite, perlite, or polystyrene resin so as not to cause eye-catching. You may use. In this case, as shown in FIG. 7, for example, a super slow-acting product such as a trade name: High Control Fertilizer (manufactured by Chisso Asahi Fertilizer Co., Ltd.) or a urea-based condensation polymer [trade name: Micrea (manufactured by Nitto Chemical Industry Co., Ltd.)] It is more preferable to fill the fertilizer bag 28 made of a fertilizer. Further, as the cylindrical body, there may be mentioned a body wall surface 17a and ones having holes 16 on both side surfaces (see FIG. 6). Further, as shown in FIG. 8, a tubular body composed of a tubular body 27 and a lid 28 and configured to be divided into two parts may be used.

Further, the entire mortar spraying surface 2 is covered from above the cylindrical body 7 fixed by the anchor bolts 8, that is, the mortar spraying surface 2 is floated by about the thickness of the cylindrical body 7. In this state, the mesh body 9 is stretched and fixed to the anchor bolt 10 that reaches the natural ground 1. As the mesh body 9, for example, a diamond wire mesh or a tensor (molding net) can be used, and the mesh is, for example,
It is preferably about 50 mm x 50 mm.

After the mesh 9 is stretched as described above,
The vegetation material 11 is sprayed over the mortar spraying surface 2 from above the net 9 by either a wet spraying method or a dry spraying method. The vegetation base formed by the vegetation material 11 sprayed on the mortar spraying surface 2 is preferably thick so that the vegetation base is, for example, about 5 to 20 cm. In this case, it is preferable that the net-like body 9 be stretched so as to be located at the middle height position of the vegetation base. This is because the vegetation base does not easily run off when the net-like body 9 is provided at an intermediate height of the vegetation base.

The vegetation material 11 is mainly composed of a plant seed and a vegetation base material such as a fertilizer, a growth base material, a water retention material, and a paste material, and it is preferable to use a kind which is resistant to drying as the plant seed. for example Kentucky 31 fescue, bermudagrass, red top, Medohagi, Yamahagi, preferably appropriately selecting and blending the seeds, such as Dianthus chinensis. Then, as the fertilizer, a mixture of fast-acting, slow-acting, and ultra-slow-acting fertilizers at an appropriate ratio is used. Also,
Appropriate materials are used for the growth base material, the water retention material, the paste material, and the like.

Then, the vegetation material is prepared by the wet spraying method.
When spraying 11, for example, in a mixer, plant seeds, vegetation base material, and water to knead the vegetation material 11,
This is discharged from the spray nozzle by the air pressure of the compressor using a mortar spraying machine to spray the mortar spraying surface 2.

Further, the vegetation material 11 is prepared by the dry spraying method.
In case of spraying, for example, by the applicant of the present application, June 1, 1991
The “spraying method of spraying base material in the greening method” (Japanese Patent Application No. 3-157568) filed on the date of application can be adopted. That is, in the spraying device disclosed in this prior application, a plant seed and a vegetation base material are mixed to form a spraying base material, which is fed to a spraying nozzle by a blower, while introducing water into the spraying nozzle. The spraying base material and water are sprayed from the spraying nozzle onto the mortar spraying surface 2.

According to an experiment conducted by the inventor, it was found that the mesh 9 was stretched at a position approximately 6 cm from the mortar spraying surface 2 and the vegetation material 11 was sprayed so that the thickness of the vegetation base became approximately 12 cm. It turned out to be preferable.

In the above-mentioned greening method, the fiber synthetic mat 4 and the tubular body 7 are integrally formed, and the unit for fixing the slope surface U is simply fixed to the slope surface as necessary. As compared with the case where the fiber synthetic mat 4 and the tubular body 7 are separate bodies, the mesh body 9 can be attached easily and quickly.

Further, since the net body 9 is held by the tubular body 7 having a height corresponding to the thickness of the mortar spraying surface 2, the net body 9 is floated from the mortar spraying surface 2. The vegetation material 11 can be thickly sprayed onto the mortar spraying surface 2 by the amount by which the net-like body 9 is floated up, and the water retention capacity of the vegetation base formed by the vegetation material 11 is enhanced accordingly. Since a plurality of holes 3 are provided on the mortar spraying surface 2 at appropriate intervals so as to open also in the natural ground 1, water from the natural ground 1 is replenished through the holes 3. It As a result, there is no fear of drying in the vegetation base.

Further, since a plurality of belt-shaped fiber synthetic mats 4 are fixed to the mortar spraying surface 2 at appropriate intervals, collection and drainage are smoothly performed, and a cylinder having a plurality of holes 6 is provided. A plurality of the shaped bodies 7 are attached to the mortar spraying surface 2 in the form of ladders across the strip-shaped fiber synthetic mat 4 at appropriate intervals via the body wall surfaces 7a, and the entire mortar spraying surface 2 is attached. Since the net-like member 9 is provided so as to cover and cover the mortar-spraying surface 2, the net-like member 9 is provided so as to float by the thickness of the tubular member 7.

Further, the roots of the plants in the vegetation base reach the natural ground 1 through the plurality of holes 3 formed in the mortar spraying surface 2, and the plants on the mortar spraying surface 2 are
Water and nutrients are also supplied from the natural ground 1. That is, since the vegetation base and the natural ground 1 are united to grow the plants on the mortar spraying surface 2, the mortar spraying surface 2 is more reliably
Is greened.

It is needless to say that the method of the present invention can be widely applied to a slope other than the mortar spraying face 2 such as a concrete spraying slope or a slope where it is difficult to grow plants such as bedrock.

There is an effect that can be. Also, the net-like body is held by the tubular body that is erected in a contour line with respect to the slope,
Since the net-like body is floated from the slope, the vegetation material can be thickly sprayed on the slope by the amount of the lifted net-like body, and the water retention capacity of the vegetation base formed by the vegetation material is increased accordingly. And since a plurality of holes are provided on the slope at appropriate intervals so as to open even in the natural ground, water from the natural ground travels along the cylinder wall surface of the tubular body,
It is replenished through this hole. As a result, there is no fear of drying in the vegetation base. Moreover, since a plurality of belt-shaped fiber synthetic mats are fixed at appropriate intervals on the slope, collection and drainage can be performed smoothly, and the tubular body straddles the belt-shaped fiber synthetic mats. The vegetation base strongly adheres to the slope without slipping off because it is erected in a contour line shape via the wall surface and the net-like body is provided so as to cover the entire slope. Furthermore, the roots of the plants in the vegetation base reach the ground through a plurality of holes formed in the slope, and the plants on the slope are also supplied with water and nutrients from the ground, and on the slope.
