Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete consolidation which is arranged vertically and horizontally on the water bottom of a river or a seashore and provides a habitat for aquatic organisms such as fishes while also preventing scouring of the water bottom. For blocks.

[0002]

2. Description of the Related Art As this kind of prior art, there is, for example, one disclosed in Japanese Utility Model Registration No. 3016551. That is, in this prior art, a block having an octagonal cross section and a concave portion on the bottom surface is applied, and the blocks are closely and vertically and horizontally aligned to consolidate the bottom of a river or other water bottom. Further, each block is provided with a hole from the outer peripheral surface toward the concave portion, and the hole is used as an entrance so that the concave portion serves as a habitat for fish and the like.

[0003]

By the way, in order for the above-mentioned blocks to function continuously as a solidification, it is necessary to maintain the arrangement of these blocks against water flow. For example, in the above prior art, a convex portion and a concave portion are provided on the outer periphery of a block, and these are fitted to each other in an adjacent block, so that the alignment is maintained even with a strong water flow.

[0004] However, in such a block, since the convex portion and the concave portion must be accurately fitted at the bottom of the water, a complicated operation is required in arrangement.
In addition, the convex portion protruding from the outer periphery not only complicates the handling of the block, but also may be damaged during transportation or during construction on site.

On the other hand, as a habitat for fish and the like, it is preferable that moss and aquatic plants are overgrown, and it is necessary to be exposed to running water to supply sufficient oxygen.

[0006] However, in the above-mentioned conventional technology, the concave portion which is to be a habitat for fish and the like is completely closed on its upper surface and the entire periphery except for the holes.
Therefore, the incidence of sunlight is blocked, and moss and aquatic plants do not grow. In addition, the water in the recesses tends to stagnate, making it difficult to supply sufficient oxygen, and is not always preferable as a habitat for aquatic organisms.

In view of the above, in the above-mentioned prior art, it is conceivable to open the upper part of the block. However,
If the upper part of the block is opened, the sunlight will be too strong this time, making it unsuitable as a habitat for fish that prefer dark places such as eels and catfish.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a rooting block which facilitates the arrangement work on the water bottom and can provide a suitable habitat for aquatic organisms.

[0009]

SUMMARY OF THE INVENTION According to the present invention, a block body having a cross-sectional shape which defines adjacent spaces at four meeting portions in the vertical and horizontal directions when closely aligned in the vertical and horizontal directions, A central opening that is open at least in the upper surface at the central portion and accommodates a boulder therein, a through hole that extends radially from the central opening and that opens to the outside of the block body in the adjacent space, and an outer periphery of the block body And a connecting arm member extending outward from the portion and being connected to each other in the adjacent space, to form a block for rooting.

The cross section of the block body is, for example, an octagon. However, a polygon other than an octagon may be used, or a circle may be used as long as adjacent spaces can be defined in four vertical and horizontal junctions when closely arranged vertically and horizontally. Absent. The central opening preferably extends through the block body in the vertical direction, and is also open to the bottom surface of the block body. Further, it is preferable to lay natural stone on the upper surface of the block body. The connecting arm member extending from the block body is preferably made of a highly rigid metal.

The central opening 13 is an opening having a circular cross section, and penetrates vertically through a portion serving as an axis of the block body 10. As is clear from the figure, the central opening 13 has a slightly smaller opening F on the bottom surface than the opening E on the upper surface, and is formed in a tapered shape so that the space therebetween is continuous.

The fishway hole 14 is a through hole having an inner diameter G that extends radially from the inner peripheral surface of the central opening 13 and has a distal end opening to the outer surface 12 for space. Each fishway hole 1
Numeral 4 extends from a portion J, which is substantially intermediate with respect to the height H of the block main body 10, along the bottom surface of the block main body 10.

The block main body 10 has a large number of raised portions 15 on its upper surface, and a connecting arm member 20 on each outer surface 12 for space.

The raised portion 15 is formed by laying a large number of natural stones on the upper surface of the block body 10. Specifically, before the concrete material constituting the block body 10 solidifies, a part of the natural stone may be buried in a position to be the upper surface, and the concrete material may be solidified as it is. The amount of protrusion of each raised portion 15 from the block body 10 may be various, but is preferably less than the maximum height K in consideration of the handleability of the block 1 for consolidation.

The connecting arm member 20 is made of a metal rod-shaped member.
It is a high-rigidity member formed in the shape of a letter, and protrudes outward from a portion below the fishway hole 14 on each outer surface 12 for space. In this case, in the present embodiment, the connecting arm member 20 is arranged so as to be curved in a U-shape along the vertical direction. In addition, each connecting arm member 2

m, the protruding amount L of the connecting arm member 20 from the outer side surface 12 for space
Is about 205 mm. The weight of a product satisfying these dimensions is approximately 2000 kg. These dimensions are merely examples, and other dimensions may of course be used.

[0020] Root stiffening block 1 constructed as described above.
As shown in FIG. 4, in a state where the outer surfaces for joining 11 are in contact with each other, they are arranged vertically and horizontally on the water bottom of a river to be prevented from being scoured. At this time, according to the above-mentioned block 1 for solidification, since the connecting arm member 20 can be used as a hanging tool, the operation for slinging the hanging wire of the crane can be performed extremely easily. become able to. In addition, if the bonding outer surfaces 11 are in contact with each other, the connecting arm member 20 contacts the other rooting block 1 even if the positions of both are shifted. Nothing. Therefore, there is no possibility that the connecting arm member 20 is deformed or damaged during transportation of the root-fixing block 1 or during construction on site.

In the solidification block 1 arranged in this manner, a columnar adjacent space 30 having a square cross section and defined by four vertical and horizontal meeting portions is defined by each of the four joint portions. The connecting arm member 20 described above is arranged in the adjacent space 30. Therefore, from the block 1 for consolidation after arrangement, the adjacent space 30
The suspension wire can be easily removed via the.
Further, in this adjacent space 30, the four connecting arm members 2
0 are connected to each other by the connecting ring 21, each consolidation block 1 is connected to the eight surrounding consolidation blocks 1 via the connecting ring 21 and the connecting arm member 20. The arrangement of each other is maintained continuously even in a strong water flow, and scouring of the water bottom can be prevented.

On the other hand, as shown in FIG. 3, a relatively small diameter, for example, 10 to 15 cm, is formed in each of the central openings 13 for each of the root-fixing blocks 1 arranged as described above.
A large boulder 40 is accommodated. Furthermore, in order to prevent the small-diameter cobblestone 40 previously accommodated from flowing away at the time of increasing water, a relatively large diameter, for example, 3
A coated boulder 41 having a size of 0 to 40 cm is arranged. For the method of storing these boulders 40 and 41, for example, a fishing method using boulders referred to as "Ishikura fishing method" or "eel kagura fishing method" is referred to.

In such a block 1, sunlight is appropriately incident on the inside of the central opening 13 through the gap between the various boulders 40 and 41, and the central opening 13
Moss and aquatic plants can be grown. in this case,
The amount of incident solar rays depends on the size of the cobblestone 4 stored in the central opening 13.
It can be appropriately adjusted according to the number and size of 0 and 41, and can cope with various aquatic organisms.

Further, from the gap between the various boulders 40 and 41, new water, that is, sufficient oxygen is always supplied to the inside of the central opening 13, so that the central opening 13 is supplied.
However, it is particularly suitable as a habitat for fish that prefer dark places such as eels and catfish, or for aquatic organisms such as river crab. In this case, with respect to the central opening 13, the fishway hole 14 serves as an entrance for these aquatic organisms, and the above-described adjacent space 3
You will be able to enter and exit through 0. In addition, moss grows quickly on the raised portion 15 made of natural stone disposed on the upper surface of each of the root compaction blocks 1, and the landscape becomes more natural.

As a result, according to the above-described block 1 for solidification, it is possible to continuously prevent scouring of a river by an easy arranging operation and to provide a suitable habitat for aquatic organisms. Can be provided.

FIG. 5 shows a concrete example of the construction of the above-mentioned root consolidation block 1 on a river.

In this construction example, first, the blocks 1 for consolidation are sequentially arranged on the water bottom of the river with respect to the existing seawall 100. In this case, a block 1 'for foundation type rooting as shown in FIG. 6 is applied to a portion close to the revetment block 100. In other words, the foundation type block 1 'is provided with a basic inclined surface 16' on a part of the upper surface of the block body 10 'so as to be perpendicular to the slope of the seawall block 100.

Next, the revetment block 1 is constructed on the basis of the foundation inclined surface 16 'of the foundation type block 1'.
The fish nest block 200 and the vegetation block 300 are laid so as to cover the 00 slope. Specifically, a fish nest block 200 is laid in a part immersed in a river,
A vegetation block 300 is laid on a portion exposed from the river.

The fish nest block 200 and the vegetation block 300 are, for example, as shown in FIG.

That is, the fish nest block 200 is composed of a fish nest front wall 201 and a fish nest retaining wall 20 arranged in parallel with each other.
2 are connected to each other by a pair of fish nest partition walls 203, a window hole 204 is provided in the center of the fish nest front wall 201, and a communication hole 205 is provided in each fish nest partition wall 203. It is a block. Note that a raised portion 206 made of natural stone is provided on the outer surface of the fish nest front wall 201, as in the case of the root consolidation block 1. For the fish nest block 200 at the top, each upper surface is covered with a lid 207.
Closed by In this fish nest block 200, a communication hole 2 is provided between a fish nest front wall 201 and a fish nest retaining wall 202.
A series of water passages through the water passages 05 are formed, and the window holes 204 of the fish nest front wall 201 function as doorways to the water passages.

On the other hand, the vegetation block 300 is a block in which a vegetation front wall 301 and a vegetation retaining wall 302 arranged in parallel to each other are connected to each other by a pair of vegetation partition walls 303. A raised portion 304 made of natural stone is provided on the outer surface of the front wall 301 for vegetation, similarly to the fish nest block 200. The vegetation block 300 is filled with high-quality soil 400 between the vegetation front wall 301 and the vegetation retaining wall 302, and is further planted with a plant having an optimum breeding environment on the riverside.

The river constructed in this way not only has the function of preventing scouring and revetment, but also has a landscape covered with natural stones instead of the existing tasteless revetment block 100. Instead, you will be able to get a very natural environment where plants and aquatic organisms actually live.

FIG. 8 shows a modified example of the above-described shoring block 1 applied to a river. The shape of the foundation type shoring block 1 ″ is different from that of the working example shown in FIG. In other words, as shown in FIG. 9, the foundation type block 1 "applied to this construction modification has a lower part of the upper surface 1 of the block body 10" as shown in FIG.
6 "is provided, on which the fish nest block 200 and the vegetation block 300 are sequentially stacked. A gap between the existing revetment block 100 and the fish nest block 200 and the vegetation block 300 is filled with a backing material 401, and a plant having the riverside as an optimum breeding environment is also planted here.

Even the river constructed in this way has not only the function of preventing scouring and revetment, but also the scenery covered with natural stones instead of the existing tasteless revetment block 100. Instead, you will be able to get a very natural environment where plants and aquatic organisms actually live.

In the above embodiment, the block body 10 has an octagonal cross section. However, the present invention is not limited to this. As long as the adjacent space 30 can be defined in each of the four vertical and horizontal meeting portions, it may be a polygon other than an octagon or a circle.

Further, although the block 1 for consolidation is arranged on the bottom of a river, the same effect can be expected even if it is arranged on the bottom of the sea, a lake or the like.

Further, the connecting arm member 20 is illustrated as being curved in a U-shape, but may have any other shape as long as it can be easily connected to each other. For example, a rod-shaped member that extends linearly and has a circular portion at the distal end can also be applied as the connecting arm member. In the above-described embodiment, when the connecting arm member 20 curved in a U-shape is applied, the connecting arm member 20 is provided in a direction curved in the vertical direction, but is curved in another direction such as the left-right direction. It may be provided as follows.

[0038] Further, although an example having four through holes 14 is illustrated, the number of through holes 14 is arbitrary. further,
The extending direction of the through hole 14 does not necessarily have to be horizontal. Although the center opening 13 has a circular cross section, the center opening 13 may have any shape. The central opening 13 does not necessarily have to have a gradually decreasing cross-sectional area toward the bottom, and does not need to be open to the bottom surface of the block body 10.

[0039]

As described above, according to the present invention,
By connecting the connecting arm members to each other, it is possible to maintain the mutual alignment against the water flow. In this case, the connecting arm members may be connected to each other in the adjacent space defined in each of the joint portions after the blocks for root consolidation are arranged closely and vertically and horizontally, so that the work becomes complicated in arrangement. Nothing. Furthermore, if this connecting arm member is made of metal, not only there is no risk of breakage during construction at the site, but also the connecting arm member is used as a hanger, and the work of arranging the blocks for rooting is facilitated. Is also possible. In addition, the central opening serving as a habitat for aquatic organisms opens at least on the upper surface of the block main body, and accommodates cobblestone inside. Therefore, in this central opening,
Sunlight will be incident as appropriate, and it will be possible to grow moss and aquatic plants, and new water, that is, sufficient oxygen will always be supplied, making it suitable as a habitat for aquatic organisms .
