る。[Detailed Description of the Invention] The present invention relates to an artificial fish reef, and its purpose is to provide a fish reef suitable for the growth of seaweed and also suitable for the habitat of small marine animals. Another objective of the present invention is to provide a fish reef having a scale and size that is difficult to construct by other means.

ものが少なくないのが現状である。Generally speaking, various artificial reefs have been proposed and put into practical use for the propagation of marine animals and plants, but with the exception of some assembled reefs made of cement, most of the unit structures are small, and their materials and surfaces vary. At present, there are only a few species that are suitable for the above-mentioned breeding due to their properties, and many species require improvement in terms of productivity and economic efficiency.
本発明は前記課題を解消すべく創案されたもので、以下
図面に従って説明する。The present invention was devised to solve the above problems, and will be described below with reference to the drawings.

魚礁が出来る。At this time, if the amounts of the slag lump l, water and cement are selected appropriately, a cement layer 3 is formed on the surface layer of the slag lump l as shown in Fig. 3. When the units of seven-point sprinkled lumps 4a to 4θ are assembled as shown in FIG. 4, the cement layers 3 are fixed to each other and the lumps 4a-4
Gaps 5a and 5b are formed between e, and after a predetermined curing period, a gigantic, amorphous fish reef resembling a giant millet stirrer is formed.

礁帯が経済的に設置できる。This amorphous fish reef can be produced at an extremely economical cost, and its large surface area and surface irregularities and voids make it suitable for the reproduction and growth of marine animals and plants. The present invention is a further development of the invention, and the manufacturing procedure thereof is shown in FIGS. 5 and 6. 6a and 6b in FIG. It is attached to the bottom plate 7 in an upright manner at appropriate intervals. Next, a copper core material (in this example, H-shaped m8) is placed on the bottom plate 7 via an appropriate spacer.Then, as shown in FIG. As shown in FIG. 7, the block 4 surrounds the copper core material 8 and solidifies to form a unit reef 10. Normally, when the unit reef 10 does not have the copper core material 8,
Although the tensile strength tends to be slightly lower than the compressive strength, the mechanical strength of the fish reef 10 of the present invention is sufficient and there is no concern at all.The copper core material 8 shown in FIG. Holes i1a''-11c, etc. and connecting fittings (not shown) are installed.Then, as shown in FIG. The assembly structure 12 is formed by connecting them using the following construction techniques.The assembly structure 12 is not limited to this embodiment, but can be in any shape such as a triangle, trapezoid, or round shape.According to the present invention Since the manufacturing method for fish reefs is simple, any number of fish reefs can be economically manufactured on land near the reef installation site.Furthermore, since the assembled structure 12 has a high mechanical strength, it can be easily manufactured by a crane ship as shown in FIG. 13a and 13b, it is possible to transport a huge assembled structure 12 of 20 to 30 m in length and width on the ocean and install it on the required seabed in an extremely short period of time. Figure 10 shows the situation of seabed installation. In the figures, the assembled structures 12a-12c of the present invention allow for economical installation of large reef zones on desired seabeds.
