Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting base and a planting jig used therefor, and more particularly to a planting base and a planting jig used therefor which are useful when greening on a slope.

[0002]

2. Description of the Related Art Conventionally, when greening a slope, the slope was covered with a net or a wire net, and vines were made to crawl over the slope to carry out the greening. However, with this method, the types of plants for greening were limited, and it was not possible to plant various plants in terms of landscape or design. For this reason, attempts have been made to perform greening using a planting base made by filling the pores of a porous body with a water retention material.

[0003] However, a planting base that is usually used is that a concrete frame is installed on a base such as a slope, and then a porous body such as porous concrete is laid and water is retained in the voids of the porous body. Since the material is slurried and poured over the slope to be filled, the water retention material flows down on the slope and is not sufficiently filled inside.

In order to sufficiently fill the porous body with the water retaining material, a method of flowing a large amount of slurry or reducing the viscosity of the slurry was studied, but in the former case, a large loss occurs in the water retaining material. However, the latter was not preferable because the effective amount of the water retention material component filled in the voids was reduced.
This tendency becomes remarkable when the slope is steep, and when the soil is sprayed onto the surface of the planting base, there is a lot of rebound of the soil, and the roots of the planted plant are sufficient for the planting base. The soil was peeled off until it became alive, and the trees could not be fully replanted.

Further, although wire mesh is stretched on the surface of the slope, it is difficult to sufficiently protect the soil.

[0006]

As described above, in the conventional planting base, it was difficult to efficiently fill the water retaining material and hold the surface soil.

The present invention has been made in view of these drawbacks, and an object of the present invention is to allow a porous body, which is mounted on a slope, to be efficiently and sufficiently filled with a water retention material, which is sudden. The purpose is to provide a planting base to which the soil can be attached even on slopes.

[0008]

The planting base according to claim 1 of the present invention comprises a porous body attached to a slope and covering the slope, and a receiving plate provided on the surface of the porous body. It is characterized by being configured.

The planting base according to claim 2 of the present invention is the planting base according to claim 1, wherein the receiving plate is fixed to a wire net provided on the surface of the porous body. And

The planting base according to claim 3 of the present invention is the planting base according to claim 1 or 2, wherein the receiving plate or the wire net holds the porous body on an inclined surface. It is characterized by being fixed to.

A planting jig according to a fourth aspect of the present invention is characterized in that the planting jig is detachably attached to the surface of the porous body, and the receiving plates are extended in multiple stages in the vertical direction.

[0012]

The functioning planting base of the present invention is composed of a porous body attached to a slope. A receiving plate is provided on the surface of the porous body. Since the porous body is filled with the water retention material, when the water retention material slurry is flowed over the slope, the receiving plate reduces the flow rate of the slurry and also on the steep slope. The filling property of the water retention material can be improved. Therefore,
The required amount of slurry is reduced, and the water retention material can be efficiently filled. Furthermore, after that, when spraying the soil,
Because the backing plate reduces the rate at which the soil is peeled off,
The plant can be stably held by the soil until the roots of the planted plant grow and root in the voids of the porous body. Further, by fixing the receiving plate to the wire net provided on the surface of the porous body, the adhesion of the soil to be sprayed is improved by the synergistic effect of the unevenness of the wire net and the receiving plate. Further, by fixing the wire netting or the receiving plate with an anchor or the like for fixing the porous body to the slope, it is possible to stably hold the water holding material or the wire netting or the receiving plate for supporting the soil. On the other hand, a jig having a vertically extending multi-stage receiving plate is removably attached to the surface of the porous body to fill the water retaining material in the porous body, and if desired, Since the attached jig can be removed, the jig can be reused.

EXAMPLE A planting substrate 10 of this example is composed of concrete (porous concrete) having continuous voids on an inclined concrete wall body 12, as schematically shown in FIG. 1 as a partial cross section. The porous body 14 is cast by using a frame, and a metal net 18 having a receiving plate (fin) 16 attached in an upward oblique direction is provided on the surface of the porous body 14. The gap between the receiving plate 16 and the wire netting 18 is filled with the soil 20 which is a material having low water permeability, and the wire netting 18 is fixed by the iron wire 22 previously installed in the porous body 14. A water retaining material is filled in the voids of the porous body 14.

In this embodiment, the porous body 14 is made of concrete having continuous voids, that is, porous concrete, as described above. Porous concrete is a hardened body obtained by solidifying an aggregate with a binder made of low-alkali cement, and continuous voids having a porosity of 20% or more are formed inside the hardened body.

As the porous body 14 used in the present invention, any porous body having water permeability can be used. In the present embodiment, the porous body 14 is made of porous concrete having continuous voids, but if the structure has voids inside, aggregates such as crushed stone, glass cullet, slag are made of concrete, asphalt, epoxy. A hardened material that is solidified with a binder such as a resin, a porous hardened material that is formed by welding the surface of a glass cullet, and further concrete, glass, polymer resin, etc., in which any continuous voids are formed with a mold or the like A hardened material or the like can also be used as the porous material of the planting base of the present invention. These porous bodies are made by directly forming a formwork on the ground, and placing it, placing it on the foundation such as the concrete of the frame that is provided on top of the ground, and using the panel of the porous body manufactured in advance in the factory on the slope. It can be installed on the slope by any method such as fixing.

A water retaining material is filled in the voids in the porous body 14 to form the planting base 10. Examples of the water-retaining material to be filled include peat moss, wood chips, straw, fibrous organic materials such as palm compost, and palm, soil such as fertile soil, soil improvers such as perlite, and the like, and mixtures thereof, and the like. From the viewpoint of neutralizing alkalinity, weakly acidic peat moss or the like is preferably used as one of the materials. When the fibrous organic material is used, in the case of a material of long fibers such as straw and palm, it is preferable to cut it into a length of 3 mm or less, and further a length of 1 mm or less. Further, a fertilizer such as an organic solid fertilizer can be mixed and used with these water retention materials.

The receiving plate 16 in the present embodiment is
Although it is attached to the wire net 18 and attached to the porous body 14, the receiving plate 16 is also attached to a plurality of wire rods that are orthogonal to the receiving plate in multiple stages, and is also attached to the square frame in multiple stages. Alternatively, it may be directly attached to the porous body 14 for use.

Further, this planting base 10 is suitable for greening slopes, but in order to plant more effectively, it serves as a cover soil necessary for germination of plants, and improves water retention. In order to maintain fertilization and the like, the top surface of the planting substrate can be coated with seed soil, fertilizer, or the like mixed with soil or a thick-layer base material, if desired.

FIG. 2 shows a wire mesh 18 with fins 16.
FIG. 6 is a cross-sectional view showing a planting base 26 of the second embodiment, in which is fixed with an iron wire 24 that is erected from the concrete wall body 12 as an anchor for the porous body 14. The wire nets 18 with the fins 16 are fixed by the iron wires 24 fixed to the base 12 in advance, and the upper surface of the planting base 26 is covered with the thin layer soil 28. In the second embodiment, since the wire netting 18 is fixed to the ground and the concrete wall body 12 provided on the ground, the wire netting 18 with the fins 16 has high stability and a planting base 26 having excellent durability is obtained. be able to. Further, as shown in the cross-sectional views of FIGS. 3 and 4, the porous body 14 can be fixed to the concrete method frame 30 provided for pouring. Depending on the type of plant to be planted or the purpose of the installation site of the planting base, the porous concrete 14 layer, which is a porous body, can be made thick as shown in FIG. You may cast thinly only in the frame of the frame.

Further, in the above-described embodiment, the wire net 18 having the receiving plate 16 is fixed to the porous body 14 or the base 12 by the iron wires 22 and 24. The jig with the receiving plates extended in multiple stages on the porous body 14
It can also be detachably attached to the surface of. That is, for example, a jig, which is the wire net 18 to which the receiving plate 16 is attached in multiple stages, is placed on the slope, that is, simply leaned against the slope and temporarily fixed with a pile or the like, or the anchor or the like. By attaching to the iron wires 22 and 24 with wires or fasteners, the wires are made detachable. After the water-retaining material is filled in the planting base, the jig detachably attached in this manner can be removed by removing the fixing portion as necessary depending on the condition and slope of the slope to be greened. Further, the jig thus removed has an advantage that it can be reused for greening a new slope.

Next, the method for laying the planting base of the present invention will be described. First, a porous body such as porous concrete is placed using a mold on the slope where greening is required. After that, a wire net having a receiving plate on the upper surface of the porous body is provided so that the receiving plate is in an upward oblique direction. A porous body, for example, porous concrete having continuous voids inside is sufficiently dried, and then a slurry-like water retaining material is filled from above the porous body.

As described above, the water retaining material is premixed with a thickener, water, etc. to form a slurry for facilitating filling. The slurry-like water retention material is poured from above the slope to the upper surface of the planting base to fill it.However, the flow velocity of the poured slurry is lowered by the receiving plates provided in multiple steps on the wire mesh, and Since it temporarily stays on the sloped part,
The water retaining material penetrates from the surface of the planting base into the voids of the porous body, so that the water retaining material can be effectively filled.

By thus filling the water retaining material, the water retaining material that has flowed over does not fill the voids and does not flow down on the surface of the substrate, so that an excessive water retaining material is not required and efficient filling can be performed. .

When the planting base is sufficiently filled with the water retaining material after the water retaining material is filled and becomes stable, the wire net with a receiving plate (jig) can be removed as described above. After removing the wire net, you may spray the soil. However, in order to prevent rebound of the soil and thick-layer base material that cover the top surface of the planting base as desired, and to improve the retention and stabilization of the soil, the jig may be installed directly on the top surface. it can.

[0025]

Since the planting base of the present invention has the above-mentioned structure, the porous body can be efficiently and sufficiently filled with the water retaining material when constructing the green space on the slope, and even on a steep slope, It is possible to stably hold the soil, and by using the planting jig of the present invention, when constructing a green space on a slope, it is possible to efficiently fill the porous body with a sufficient water retention material, It has shown the excellent effect that the jig can be reused.
