Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block used for revetment work of rivers and lakes, and more particularly to an environmental protection block useful for improving a natural scenery in which waterside plants and the like are vegetated and greened.

[0002]

Heretofore, in the revetment of rivers and lakes, blocks made of concrete, tetrapots, royal walls, and the like have been often used, resulting in an artificial and unnatural landscape. In recent years, the importance of preserving and cultivating natural landscapes has been recognized, and various vegetation methods have been proposed and implemented, but no satisfactory method has been found.

[0003] For example, the use of a vegetation green block made of a concrete frame makes it possible to plant waterside plants and greatly improve the landscape, but it is difficult to obscure the concrete surface above the frame. No, some unnatural scenery remains. For this reason, attempts have been made to lay natural stones such as chestnut stone on the concrete surface, but this has not yet led to a satisfactory landscape.

[0004] Alternatively, attempts have been made to lay porous natural stones such as pumice stones. Porous stones such as pumice are excellent in water retention, and excrement and dead bodies of micro-animals breeding in the fine holes become fertilizers, so that an environment suitable for plant growth can be provided. As a result, it was expected that moss and grass would grow quickly in the place where the porous stones were laid, and that an almost satisfactory natural landscape would be obtained. However, porous stones such as pumice have poor strength, and are easily broken by various natural or artificial impacts or freezing of water accumulated in small holes, and may be blown off by wind or the like. For this reason, there has been a problem that moss and grass do not grow smoothly or wither even if they grow.

Therefore, the present inventor has proposed a block used for revetment work of rivers and lakes, which is provided with a vegetation part such as a waterside plant and covers a frame forming the block with natural stones and plants. As a result of intensive studies on environmental conservation blocks that can further improve the natural landscape, the present invention has been achieved.

[0006]

The present invention takes the following means to solve the above-mentioned problems. That is, the gist of the environmental protection block according to the present invention is a block provided with vegetation and used for revetment work of rivers and lakes, and a porous stone is formed on an upper surface of a frame forming the block. The natural stone boulders were exposed and arranged.

Another aspect of the environmental protection block according to the present invention is a block provided with vegetation and used for revetment work of rivers and lakes, and is provided on an upper surface of a frame forming the block. At least the porous stone is disposed so as to be exposed, and the porous stone is embedded and fixed in the frame.

Another aspect of the environmental protection block according to the present invention is a block provided with vegetation and used for revetment work of rivers and lakes, wherein the block is formed in an octagonal column shape. It is in.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an environmental protection block according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an environmental protection block 1 according to the present invention.
FIG. 4 is a diagram schematically illustrating an example of an octagon 0, in which a vegetation portion 14 is provided at the center of an octagonal cylindrical frame 12, and a porous stone 18 and a boulder 20 are arranged on an upper surface 16 of the frame 12. Has been established. Further, four hook-shaped connecting members 22 for connecting to another adjacent block 10 are provided on the side surface of the frame 12.

In the block of this embodiment, the connection between the adjacent blocks 10 is performed by a ring-shaped connecting member 26 via a hook-shaped connecting member 22 as shown in FIG. The four hook-shaped connecting members 22 are connected to the ring-shaped connecting members 26.
The four blocks 10 are connected to each other by passing through, and a substantially rectangular vegetation space 28 is formed around the connection portion where plants can be vegetated. Similarly, block 10
By connecting each of the hook-shaped connecting members 22 provided at the four corners, a large-area seawall can be integrally connected. As shown in Fig. 3, it becomes a seawall with a beautiful mosaic design. However, the connection method between the blocks according to the present invention is not limited to this example, and may be implemented by a connection using a bolt, a connection using an uneven engagement, or the like.

In the present embodiment, the shape of the frame 12 is an octagonal column, but is not limited to this. The shape may be a polygonal column such as a triangle, a quadrangle, a hexagon, or the like, or a column. The size is determined in consideration of the workability of transportation and construction, the molding cost, and the like.
About 2 m is preferable. The material is not limited, but it is preferable to use concrete because it is easy to mold and low in cost.

The vegetation section 14 houses a vegetation base. Since the block 10 of this example is supposed to be mainly used underwater or at the waterside, the cobblestone 20 made of chestnut stone and the vegetation soil are wrapped in sandbags or the like so that the vegetation base is not washed away by the water current. A waterside planting bag 24 and below it,
And a water-permeable vegetation medium 25 made of chestnut stone or the like. Cobblestone 20 placed on top of waterside planting bag 24
Is used for the purpose of preventing the waterside planting bag 24 from being washed away by the water flow of the river and for bringing it closer to a natural landscape. The configuration of the vegetation base is appropriately designed according to the place and environment where the block 10 is used. A vegetation mat or the like can be used when the influence of the water flow is small, and a special protective material does not need to be used on a slope having a relatively gentle slope with a small influence of the water flow.

The porous stone 18 disposed on the upper surface of the frame 12
Porous natural stones such as pumice, rock rhinoceros, and hyuga stone, or porous artificial stones such as vermiculite, perlite, unglazed pottery stone, and foamed concrete are used. Examples of the cobblestone 20 provided together with the porous stone include natural stones such as cobblestone, chestnut stone, and crushed stone, or artificial stones made artificially from waste or the like. Cobblestone 2
The purpose of using 0 is to improve the landscape by covering the top of the block and to protect the brittle and easily crushed porous stone. Therefore, it is preferable that the size of the cobble stone 20 is at least as large as that of the porous stone, and the cobble stone 20 and the porous stone are uniformly mixed and dispersed without being partially biased. As an arrangement method, the porous stone 18 can be laid on the upper surface of the block, but since the porous stone 18 has a relatively small specific gravity, the porous stone 18 is easily moved and moved by a water flow or wind. Therefore, when the block 10 is formed, the boulders 20
And the porous stone 18 are preferably embedded in the block 10 and disposed.

The porous stone 18 is excellent in water retention, and the excrement and the dead body of the small animal breeding in the fine hole serve as fertilizer, thus providing an environment suitable for plant growth. However, there is a problem that the porous stone 18 is relatively fragile and thus easily crushed, and is lightweight and easily scattered by a water flow or the like. In the present invention, since the porous stone 18 is disposed in a mixture with the cobblestone 20 containing chestnut stone or the like, the impact on the porous stone 18 is not interrupted by the cobblestone 20 and crushed. Shape is maintained. As a result, moss and grass grow quickly, and in harmony with the appearance of the cobblestone 20, a substantially satisfactory natural landscape can be obtained.

Although the embodiments of the environmental protection block according to the present invention have been described in detail, the present invention is not limited to the above embodiments.

For example, FIG. 4 shows an example in which the invention is applied to a fish nest block. A space 30 is provided below the environmental protection block 10 shown in FIG. It is configured. In order to provide the space 30 below the environmental protection block 10, a drop lid 33 is provided at an intermediate portion of the block 10 so as to allow water to flow. If a large number of such blocks 10 are connected,
As shown in FIG. 5, the space portions 30 are connected in a grid pattern by the openings 32, and a wide space suitable for a fish nest can be formed. FIG. 6 shows an example of the drop lid 33 that is located above the space 30 and receives the waterside planting bag 24.

FIGS. 7 and 8 show examples of environmental protection blocks suitable for a slope at a position relatively distant from the waterside.
As in FIG. 1, porous stones 18 and cobblestones 20 are disposed on the upper surface 16 of the frame 12, but the configuration of the vegetation 14 is different. That is, since there is no fear of the water flowing away, the chestnut stone or the cobblestone 20 is not laid on the flower greening bag 34, and relatively small-sized soil 35 is laid below.

In block 10 shown in FIG.
A flowering greening bag 34 for vegetation of flowers and trees is used, and the area of the vegetation part 14 is set to be large, which is suitable when the slope angle of the slope is relatively gentle. FIG.
In the block 10 shown in FIG. 1, a large number of small flower greening bags 34 are used to disperse a small height of flowers, and are arranged between the blocks 10. Suitable for steep angles. That is, when arranging the block 10 on a slope having a steep angle, the topsoil is easily washed away from the vegetation part 14 by rainwater or the like, and easily falls. For this reason, the vegetation part 14 is divided into a plurality, and the area of each vegetation part 14 is formed small.

As described above, since the porous stone has a small specific gravity and is light, it may be washed away by a river current or blown off by a strong wind. Therefore, simply laying on the upper surface of the block cannot maintain its excellent vegetation promoting action stably and for a long period of time. In order to maintain the vegetation promoting effect stably, the porous stone must be fixed to the upper surface of the block. It is preferable to embed and fix integrally when forming the block, instead of simply laying it. The porous stone alone or a mixture with natural stone boulder may be embedded and formed only in the upper surface of the block, or may be embedded in the entire block and formed, and then the upper surface may be cut to expose the porous stone. Can also.

The revetment blocks are not used alone, but are used in combination of tens or hundreds. Therefore, it is important not to evaluate the design of individual blocks, but to design the entire revetment that is assembled and completed. As shown in FIG. 2, a substantially quadrangular vegetation space 28 is formed around the connecting portion of the octagonal column-shaped block, and the entire seawall connected in a planar manner is formed as shown in FIG. 3 or FIG. A good mosaic design. By arranging and arranging an appropriate plant in each of the vegetation part 14 in the block and the vegetation space 28 between the blocks, it is possible to create an excellent landscape in which artificial patterns and natural vegetation are in harmony.

For example, a revetment as schematically shown in FIG. 9 can be constructed by using the environmental protection block according to the present invention. Block 36 made of concrete
Has a shape similar to that shown in FIG.
It is formed in an octagonal cylinder shape of × 1 m and height of 0.6 m. The vegetation part 14 of the block 36 has a waterside planting bag 24 (not shown) having a size of 45 cm × 45 cm and a height of 10 cm.
Can be accommodated. Block 38 is for a fish nest similar to that shown in FIG.
The only difference is that a space 30 (not shown) is provided. Therefore, it is constructed so that the flow of water is secured at the center of the river and vegetation is possible. In addition, on the revetment side of the river, a place that becomes a fish nest is formed, fish is bred, and the river becomes more natural.

The block 40 is for a slope similar to that shown in FIG. 7, and is formed in an octagonal cylinder having a size of 1 m × 1 m and a height of 0.3 m. Blocks 36, 3
Similarly to 8, the vegetation part 14 accommodates a flower greening bag 34 (not shown) having a size of 45 cm × 45 cm and a height of 10 cm. Each block upper surface 16 has a diameter of 30
A pumice stone and a chestnut stone having a size of 100 mm to 100 mm are embedded and exposed and arranged at the time of block molding. Block 3
A natural stone-stoned area 42 is applied to a flat portion where the block 8 and the slope block 40 intersect. The construction is such that 42 parts of earth and sand are not washed away.

Further, for example, the waterside planting bag 24 of the block 36 contains eel rhizomes, and the waterside planting bag 24 of the block 38 contains rhizomes of squid and sekisho. In addition, seeds such as cosmos, bermudagrass, and wildflower are stored in the flower greening bag 34 of the block 40, and cat willow seedlings are planted in some blocks.

A seawall as schematically shown in FIG. 10 can be constructed by using the environmental protection block according to the present invention. Blocks 36 and 38 may be the same as those used in the above embodiment. The block 44 is for a slope similar to that shown in FIG. 8, and for example, an octagonal cylinder having a size of 1 m × 1 m and a height of 0.3 m is used. For example, 15cm x 3
Flowering greening bags 34 (not shown) each having a size of 5 cm and a height of 10 cm are provided in the block at a ratio of four and two between the blocks.

Although various embodiments of the present invention have been described above, the present invention is not limited thereto, and the material and shape of the environmental protection block, the configuration of the vegetation, the porous stone, and the natural stone may be used without departing from the spirit of the present invention. The type and shape of the cobble stone, the method of fixing the porous stone, and the like can be implemented in various modified, modified, and modified modes based on the knowledge of those skilled in the art.

[0027]

According to the environmental protection block of the present invention, moss and grass can be propagated by the porous stone disposed on the top surface of the block, and the artificial appearance of the block can be covered. The scenery can be harmonized with. In addition, by arranging cobblestones such as natural stones on the top surface of the block together with the porous stones, it is possible to reduce the impact of the porous stones and prevent the porous stones from being crushed. Can be bred and maintained stably. Alternatively, by embedding and fixing the porous stone on the upper surface of the block, it is possible to prevent the outflow of the porous stone and the like, so that the growth of moss and grass is stabilized, and a natural landscape can be maintained. In addition, by making the shape of the environmental protection block an octagonal cylinder, a vegetation space is formed between the blocks, and as a whole, a seawall can be beautifully designed in a mosaic shape.
