〔産業上の利用分野〕
この発明は、潜堤の改良に関するものであり、−層詳細
には、魚巣機能を具える潜堤に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement of a submerged embankment, and more particularly to a submerged embankment having a fish nest function.
従来より、海岸などの浸食対策に使用される構造物とし
ては離岸堤や潜堤などが知られているが、このうち離岸
堤は堤体が海岸から少し離れた海面上に突出するような
構成であるため景観上好ましくなく、近年は堤体の天端
面が海面下にあって景観を阻害することなく静穏海域を
確保できる潜堤が積極的に採用されている。Offshore breakwaters and submerged breakwaters have traditionally been known as structures used to prevent erosion on beaches, etc. Among these, breakwaters are structures in which the breakwater body protrudes above the sea surface a little distance from the coast. Because of this structure, it is not aesthetically pleasing, and in recent years, submerged levees have been actively adopted because the top of the levee body is below the sea surface, ensuring calm waters without disturbing the landscape.
ところで、この潜堤においては基礎マウンド上に積み上
げた捨石やブロックにより堤体が構成されているため、
堤体内部の空隙が極めて少なくしかも外部光もさし込ま
ないので魚巣としての機能に欠け、また捨石やブロック
の使用量も多くなるので構築コストが嵩み、さらには堤
体内外の海水交換機能も満足とは言えないなど解決すべ
き種々の課題が指摘されていた。By the way, in this submerged embankment, the embankment body is composed of rubble and blocks piled up on the foundation mound, so
Since there are very few voids inside the dam body and no external light penetrates, it lacks the function as a fish nest, and the construction cost increases because a large amount of rubble and blocks are used.Furthermore, it is difficult to exchange seawater inside and outside the dam body. Various issues were pointed out that needed to be resolved, including unsatisfactory functionality.
そこで、この発明では基礎マウンド上に好ましくは頂部
に採光部を形成した箱形の本体ブロックとこの本体ブロ
ックに連通ずる魚道ブロックとを配設する構成を採用す
ることにより、堤体に魚巣としての機能を付与するとと
もに構築コストの低減をも図ろうとするものである。Therefore, in this invention, by adopting a configuration in which a box-shaped main body block with a lighting section preferably formed at the top and a fishway block communicating with this main body block are arranged on the foundation mound, the embankment body can be used as a fish nest. The aim is to provide these functions as well as reduce construction costs.
そして、具体的には所定個所に採光部を形成した複数の

で被覆することにより構成するのが好ましい。Specifically, a plurality of main body blocks each having a lighting section formed at a predetermined location are arranged in series on a foundation mound, and the internal spaces of these main body blocks are communicated with each other, while a fishway is installed on the side of a predetermined main body block. It is preferable to connect the blocks, laminate a filling material on the upper part of the fishway block and the spaced apart part thereof, and further cover the bottom and top portions of the filling material with a covering material.
また、この場合、本体ブロックは、箱形本体の少なくと
も一方の対向する側面に連通口を開設するとともに頂部

。Further, in this case, the main body block has a communication port on at least one opposing side surface of the box-shaped main body, and a slit-shaped lighting section that communicates with the internal space at the top,
The fishway block is constructed by opening a communication hole for the fishway block as necessary on the other opposing side, and the fishway block is formed of a generally inverted U-shaped block with both ends open and the bottom open. It is preferable to form a flange along the bottom edge of the glyph block.

その頂部などに形成した採光部を介して外部光がさしこ
むだけでなく、各魚道ブロックは魚介類が内部空間へ出
入りするための出入路として使用されるので堤体に魚巣
としての機能が付与できる。In the submersible embankment according to the present invention, not only external light shines into the internal space of the main block through the lighting section formed at the top of the main block, but also each fishway block is an entrance/exit path for fish and shellfish to enter and exit the internal space. Since it is used as a fish nest, the embankment body can function as a fish nest.
次に本発明に係る潜堤の好適な実施例につき添付図面を
参照しながら以下詳細に説明する。Next, preferred embodiments of the submerged embankment according to the present invention will be described in detail with reference to the accompanying drawings.

ている。That is, the submerged embankment 10 according to the present invention is shown in FIGS. 1 and 2.
As shown in the figure, for example, a foundation mound 12 of a predetermined length is formed using rubble or the like on the seabed at a depth of about 6 m to 10 m, and a slit-shaped lighting section 14 is provided along the longitudinal direction of this foundation mound 12. Box-shaped main body blocks 16 are arranged in series to communicate with each other, and fishway blocks 1 are installed on both sides of a predetermined main body block 16°.
8.18, and stack stones 20 on top of these fishway blocks 18 and in the space between them, and then cover the slope and top portions of the stones 20 with a covering material such as a covering stone or a covering block. 22.

構成されている。The main body block 16 consists of a box-shaped main body 24 made of reinforced concrete or the like with an open bottom, and has a communication port 26.2 in at least one opposing side wall of the main body 24.
6 is opened, and a plurality of slit-shaped lighting sections 14 are opened at the top in the direction of the communication port 26 and 26.

（第３ａ図および第３ｂ図参照）。The fishway block 1 is provided on the other opposing side surface of the predetermined main body block 16', that is, on both side walls in the elongated direction.
8, the internal space 16a of the main body block 16'
A communication hole 28 is provided to communicate the fishway 18a with the fishway 18a (see FIGS. 3a and 3b).
また、魚道ブロック１８は、本体ブロック１６と同様に

成すれば好適である（第４ａ図および第４ｂ図参照〉。The fishway block 18 is made of reinforced concrete or the like like the main block 16, and has an open bottom and a flange 30 on the edge for the purpose of stabilizing the block and preventing it from sinking.
．． 30 to form a substantially inverted U-shape, it is preferable to form a sheath stopper 32 on the top end of the fishway block 18' used at the end (see Figures 4a and 4b).

ることは言うまでもない。The fishway block 18 may include a structure in which a shelf 34 is formed in the fishway 18a (see Figure 5a), or a double structure in combination with an internal fishway pro-7ri 36 with a smaller circumference (see Figure 5a). It goes without saying that a structure constructed by covering a block body using a large side gutter, a manhole, etc. with a cover member 38 (FIG. 5C) can also be used as appropriate.

通路として機能することになる。In the submerged embankment according to the present invention configured as described above, not only external light enters into the interior of the embankment body, that is, each main body block 16 (16゛) through a large number of slit-shaped lighting sections 14, but also the lighting section 14 and fishway block 18 (1B'
) functions as a passageway for fish and shellfish etc. to enter and exit the internal space 16a of the main body block 16, or as a seawater flow passageway to the inside and outside (inside and outside) of the embankment body.

。As mentioned above, according to the submersible embankment of the present invention, a large space with a fishway is formed inside the embankment body, and external light enters into this internal space (fish nest) from the light-taking part such as the top, so that various types of light can be seen. Since fish and shellfish can settle in a suitable manner and young children can be protected and raised, it can not only be used suitably as a fish reef or seaweed bed, but also promote the exchange of seawater between the inside and outside of the embankment body. In addition, since the porosity of the embankment body is large, the amount of filling material and covering material used is not small, making it economical, and furthermore, the entire construction work, including leveling of the foundation mound, can be carried out easily. Therefore, it has various advantages such as being able to significantly reduce construction costs.

Of course, various design changes can be made within the scope.
