Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a river weir, a waterway wall,
The present invention relates to a concrete structure having a planting layer in which a plant can grow on the surface of a concrete structure such as a retaining wall, and a method for producing the same.

[0002]

2. Description of the Related Art In conventional concrete structures such as river dams, waterway walls, retaining walls, etc., a formwork corresponding to the shape of the structure is provided, and ready-mixed concrete is placed in the formwork to produce concrete. A structure is made and the surface of the structure is finished with a trowel or the like.

[0003]

The concrete structure described above does not harmonize with the surrounding scenery because the skin of white concrete is exposed on the surface, and at the time when grass and flowers bloom on the shore of the river. Then, there is a problem that it gives an unnatural feeling.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a planting layer which allows plants to grow on the surface of a concrete structure in order to match the surrounding landscape. A concrete structure and its manufacturing method are provided.

[0005]

A concrete structure provided with a planting layer according to claim 1 is a concrete structure body, and a planting layer having a large number of recesses formed on the surface of the structure body. And a vegetation material obtained by mixing plant seeds, fertilizers, and water retaining members attached to the planting layer.

According to a second aspect of the present invention, there is provided a method for producing a concrete structure having a planting layer, in which fresh concrete is cast to provide a structure body, and before the raw concrete hardens, plant seeds and fertilizers are applied to the surface thereof. After attaching the vegetation material formed by mixing the water retention member and the water retaining member, the surface of the vegetation material and the fresh concrete is struck by a sharp object such as a stick to form a vegetation layer having a large number of recesses, and the vegetation layer The feature is that the concave portion of is filled with the vegetation material.

According to a third aspect of the present invention, there is provided a method for producing a concrete structure having a planting layer, in which fresh concrete is poured to provide a structure body, and the surface of the fresh concrete is sharpened with a stick or the like before hardening. It is characterized in that a planting layer having a large number of recesses is formed by abutting with a material and a vegetation material obtained by mixing plant seeds, fertilizers and a water retaining member is attached to the planting layer.

[0008]

According to the present invention, the strength of the concrete structure is ensured by the structure body. Also, because the vegetation material was attached to the planting layer having a large number of recesses formed on the surface,
Fertilizer and water contained between the water retaining members are supplied to the seeds of the plant mixed with this, and the plant grows on the surface of the concrete structure.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. First, the formwork 1 is provided on the construction site G. As shown in FIGS. 1 and 5, the concrete structure 2 includes a plurality of layers 3 a to 3 of ready-mixed concrete inside the formwork 1.
The structure main body 3 is formed by piling up on n, and the structure main body 3 is cured and cured to form the structure main body 3. First, as shown in FIG. 2, green concrete is poured into the inside of the form 1 to form the first layer 3 a of the structure body 3. This green concrete is usually composed of cement, aggregate such as sand, gravel and crushed stone, and water.

Then, before the first layer 3a is hardened, the vegetation material 4 is attached so as to cover the left and right end surfaces. The vegetation material 4 is a mixture of plant seeds, fertilizer, soil and a water retaining member. As plants, flowers that grow naturally on river beds,
Clover, Bermuda glass, Kentucky bluegrass, creeping red fest, hyrant bentgrass, safari, etc. are preferable, and as water retention material, finely crushed materials such as soil, river sand, rocks, crushed bricks, roof tiles, pottery, etc. A crushed product of lightweight cellular concrete, a product obtained by finely tearing paper or cloth and hardening it, or a crushed product of wood or sawdust is preferred. Further, the seeds included in the vegetation material 4 are not limited to one kind, for example, on the structure body 3,
Different seeds may be mixed in the middle and lower layers.

Next, in FIG. 3, before the first layer 3a is hardened, the surface of the first layer 3a is pierced with a pointed object such as a rod 5 from above the vegetation material 4. ~ 8
A planting layer 6 having a recess 6a with a depth of cm is formed. At the same time, the recesses 6a are filled with the vegetation material 4. Next, in FIG. 4, green concrete is poured on the first layer 3a to form the second layer 3b of the structure body 3. Then, in the same manner as described above, the vegetation material 4 is attached to the end surface of the second layer 3b, and the surface thereof is abutted with a pointed object such as a rod 5 to form a planted layer 6. This is repeated to form the third layer 3c,
Finally, the uppermost layer 3n is formed (see FIG. 5). On the uppermost layer 3n of the structure body 3, a vegetation layer 6 is also formed on the upper surface, and the vegetation material 4 is attached to the upper surface. And
When the structure body 3 is cured and hardened, the concrete structure 2 is formed.

In such a concrete structure 2, the overall strength is ensured by the structure body 3.
Further, the vegetation material 4 is attached to the surface of the planting layer 6 and the large number of recesses 6a. The seeds of the vegetation material 4 are supplied with nutrients from fertilizers, water stored between the water retaining members, and light is supplied from the outside, so that the plants P grow from the seeds so that the concrete structure 2 Cover the surface (see FIGS. 1 and 7). By preparing a plurality of vegetation materials 4 mixed with different seeds and using different vegetation materials 4 for each layer of the structure body 3, it is possible to cover the concrete structure 2 with a plurality of different plants.

According to the above-described embodiment, the strength of the concrete structure 2 can be ensured and the surface of the concrete structure 2 can be covered with the plant P. The skin is not exposed and has the effect of blending well with the surrounding natural scenery. In addition, since a large number of recesses 6a are formed in the vegetation layer 6, the vegetation material 4 can be reliably attached to the vegetation layer 6.

The present invention is not limited to the above embodiment, but when the first layer 3a to the uppermost layer 3n of the structure body 3 are formed, the sticks 5 and the like are sharpened before each surface is cured. After arranging them to form a planting layer 6 having a large number of recesses 6a, curing and hardening the structure body 3, the surface of the planting layer 6 and the recesses 6a are attached so that the vegetation material 4 is applied. May be. According to this embodiment, the range for attaching the vegetation material 4 can be freely selected. Therefore, if a plurality of vegetation materials 4 in which seeds of different plants are mixed are prepared and the vegetation materials 4 and their mounting ranges are selected according to the design, the surface of the concrete structure 2 can be decorated with a desired design. The effect is that it can be done.

8 to 16 show an embodiment in which the present invention is applied to another concrete structure, FIGS. 8 and 9 show an embodiment applied to the retaining walls 11 and 12, and FIG. , Applied to the dam 13, FIG. 11 applied to the waterway wall 14, FIG. 12 applied to the boundary block 15,
13 is applied to the artificial rock 16, FIGS.
Is applied to blocks 18 and 19 on which natural stones 17 are arranged. Also in these examples, the same effects as those of the above-described examples are obtained.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the vegetation material is not limited to the one that grows plants, but may be the one that grows moss and the like. Various modifications are possible without departing from the above.
