[0002]

2. Description of the Related Art As one of slope protection techniques, there is known a method of spraying a solidifying material such as mortar or concrete onto a slope to prevent the slope from collapsing. It is pointed out that slopes constructed in this type of publication give an inorganic texture because the concrete of the lining layer remains exposed. On the other hand, interest in greening methods that harmonize with the surrounding landscape has increased,
Examples of such construction are also increasing. In general, the greening method employs a technique of spraying a plant growth base material on a slope in a layered manner and then greening the plant growth base material. The slopes that can be employed are basically limited to cut slopes. The reason that the slope covered with the lining layer of the consolidation material is not targeted is that if the revegetation method for the cut and sand surface is applied as it is on the lining layer of the consolidation material, the lining layer will grow In order to separate the base material and the ground, the presence of the lining layer not only inhibits the growth of the plant root system,
This is because the plant growth base material formed on the surface of the lining layer has a high possibility of being eroded or collapsed by rainwater or the like, and its application is difficult. As another method of greening the slope covered with the lining layer, it is conceivable to remove the entire lining layer and then apply the above-mentioned greening method, but the time and cost required for removing the lining layer can be considered. But large and poorly realized.

[0003] Accordingly, the applicant has filed a patent application on a method in which an inhibitor can be set up on the surface of a lining layer and fixed thereon, and a plant growth base material can be sprayed on the deterrent body to measure greening from above the lining layer. The application has been filed in Japanese Patent Application Laid-Open No. Hei 7-258172. Since this deterrent body is a long band-shaped wire net, it has been found that there is room for improvement in terms of transportability from the factory to the site, storage and installation.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and provides a support which has a high effect of preventing a plant growth substrate from collapsing and has excellent transportability and handleability. If there is a lining layer made of a consolidation material, as well as the slope of the plant, the greening can be achieved without removing the lining layer, and the plant growth base material has a high effect of preventing collapse of the plant growth base material. Is to provide.

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

<A> Overall Structure As shown in FIG. 2, the support 1 for a plant growth substrate of the present invention comprises:
A plurality of strips 10 and a connector 2 for connecting the strips 10
0 and an installation pin 30 that passes through the inside of the connecting tool 20.

<B> Band-shaped body The band-shaped body 10 is, for example, a plate having a rectangular shape as shown in FIG. 1 or FIG. 2, and is a member used by connecting a plurality of sheets in a column. As the band 10, for example, a perforated plate having appropriate flexibility such as a wire mesh or a lath wire mesh, or a resin, metal, or wooden plate may be used. Further, the mesh shape and mesh pitch of the belt-shaped body 10 are not limited to the shapes and pitches disclosed in the respective drawings, and any shape can be adopted as long as it can be connected by the connecting tool 20 described later. As shown in FIG. 3, a connecting member 2, which will be described later,
The vertical lines 111 are arranged so that connection by 0 is easy.

<C> Connecting Tool The connecting tool 20 is a member for connecting the strips 10 at their ends 11. As shown in FIGS. 2 and 3, it is conceivable to use a connecting member 20 in which a wire is formed in a coil shape. That is, the connecting tool 20 includes the vertical lines 111 of the ends 11, 11 of the opposed strips 10, 10.
By winding and attaching to the belt 111,
Connects each other. The dimensions of the coil-shaped connecting member 20 may be the same as the length of the end portion 11 of the strip 10, and the number of coils wound with the wire may be a multiple of the pitch between the horizontal lines 112, 112 of the strip 10. Conceivable. Thus, when the strips 10 are connected to each other, the horizontal line 112 of the strip 10
The same number of coils can be located for each pitch of. In addition to connecting the strips 10 together, a connecting tool 20
Is an insertion hole 2 through which an installation pin 30 described later is inserted.
Form one. Therefore, the connecting member 20 is manufactured so as to have an inner diameter having a space enough to allow the installation pin 30 to pass therethrough even after the belt-shaped members 10 are connected to each other. Conventionally, the following problems have occurred when the belt-like body is configured as a connectable divided body. First, in order to connect the respective band-shaped members, it is necessary to form, for example, a loop-shaped connecting portion at both ends of the band-shaped member in addition to the cylindrical portion for the mounting pin. Further, in order to rotatably connect the loop-shaped connecting portion of the above-mentioned band-shaped body, a pin material that penetrates the loop is separately required. On the other hand, the use of the coil-shaped connecting member 20 facilitates the connection between the strips 10 and does not require the processing of the connecting pin material or the loop-shaped connecting portion.

<D> Installation Pin As shown in FIGS. 1 and 4, the installation pin 30 is
A plurality of strips 10 connected to each other by a long
This is a member for fixing on the slope 3 covered with. The installation pin 30 is inserted into the insertion hole 22 of the connecting tool 20 for connecting the end portions 11 of the strips 10 to each other, thereby forming the strip 1.
Becomes one with 0. That is, the installation pin 30 is inserted through the insertion hole 21 of each connecting tool 20, penetrates the lining layer 2, and is driven into the ground of the slope 3, so that the plurality of strip-shaped bodies 10 connected in a long manner are connected. It is fixed on the lining layer 2. In addition, by inserting the installation pin 30 into the insertion hole 21 of each connecting member 20 for connecting each band 10, the movement of each band 10 on the slope 3 can be restricted. It is conceivable to use a known anchor body or the like as the mounting pin 30.

[0012]

[Construction method] The slope greening method of the present invention will be described below.

<A> Laying of Support FIG. 1 is a perspective view of a slope 3 covered with a lining layer 2 of a consolidated material. First, a support 1 for a plant growth substrate is provided on the surface of the lining layer 2.
(Hereinafter referred to as support 1) is laid with continuity in the transverse direction of the lining layer 2. Since the support 1 is configured by rotatably connecting the plurality of strips 10 with the connector 20, the support 1 is transported to a slope at a site in a state of being folded from a factory or the like. The folded support 1 carried into the site is
It is laid on the lining layer 2 in a developed state, and when laying a plurality of layers, they are laid hierarchically at predetermined intervals. At this time, the support 1 is placed vertically on the lining layer 2 in order to support the plant growth substrate 4 to be sprayed later. The positioning of the support 1 is performed by inserting the installation pins 30 into the connecting tools 20 attached to the end portions 11 of the respective strips 10 constituting the support 1 and driving the fixing tool 30 into the lining layer 2. On this occasion,
Each of the strips 10 constituting the support 1 has both end portions 1.
At the position of the connector 20 located at 1, it is fixed to the lining layer 2 by the installation pin 30, so that the movement in the lining layer 2 is restricted.

<B> Opening Opening Next, as shown in FIG. 4, a part of the lining layer 2 located between the support 1 and the support 1 is bored to expose the ground. 2
a is formed. The opening 2a is opened in consideration of the viability of the root system of the plant 5, and its shape, size, number of openings, and opening position are appropriately selected and determined according to the type of the plant 5 and the vegetation form. . The laying of the support 1 and the opening 2a described above may be performed in reverse order or may be performed in parallel.

<C> Spraying / Vegetation of Plant Growth Substrate To grow a plant, the plant growth substrate 4 needs to have a certain thickness or more. Therefore, the lining layer 2 having the opening 2a
Then, the plant growth substrate 4 is sprayed in a layer form until the support 1 is hidden. The plant growth base material 4 is mainly composed of sandy soil, in which dry cement is mixed, in which soil is mixed with short fibers, or where necessary, a fertilizer or a soil conditioner is mixed therein. Can be adopted. The plant growth substrate 4 immediately after spraying has poor shape stability and tends to collapse, but in the present invention, since the support 1 is continuously laid in the transverse direction of the lining layer 2, the support 1 Has a high dispersing effect of dispersing the load weight acting on a part of the others. Therefore, the support 1 supports the plant growth substrate 4 and effectively prevents the plant growth substrate 4 from collapsing. Next, the plant growth substrate 4
After laying a net 6 such as a wire net on the surface of a, the plant growth base material 4b is sprayed thin enough to hide the net 6. The plant growth substrate 4b is obtained by mixing plant seeds and fertilizer into sandy soil. Alternatively, a young plant, a young tree, a bulb, or the like may be planted on the sprayed plant growth substrate 4b.

<D> Growth of Plant The plant 5 first establishes a root on the plant growth substrate 4. Since the opening 2a is opened in the lining layer 2, the root system of the plant 5 grows through the opening 2a to the lower ground side of the lining layer 2.

[0017]

As described above, the present invention has the following effects. <B> The continuous growth support can reliably and efficiently support the plant growth substrate, and thus has a high effect of preventing the plant growth substrate from collapsing. <B> After the continuous belt-shaped support is vertically placed on the lining layer, the laying operation is completed only by fixing the support in places, so that the support laying work can be performed quickly and easily. <C> Since the support is formed by connecting a plurality of strips so as to be freely rotatable, it can be folded freely and is excellent in transportability, handling, and installation. <D> The formation of an opening in a part of the lining layer does not obstruct the growth of the root system. Therefore, the entire greening of the slope where the lining layer exists can be easily performed without removing the entire lining layer. <E> By simply inserting the installation pin into the tubular part formed on the belt-shaped support and driving it, the support can be laid down on the slope in a disciplined manner, so that the support is not only easy to lay, but also installed. Since the support does not move with respect to the pin, a high support force can be secured.
