あることを知シ、研究の結果、本発明を開発したもので
、以下図面に従って説明する。As a well-known method for artificially cultivating edible seaweed, for example, gametophytes germinated into thin wires are suspended in the sea over the summer, and the thin wires are cut short after waiting for the emergence of young shoots from fertilized eggs in autumn. Methods of cultivating seaweed by placing them on a rope and hanging them in the sea in a loop-style manner or by stringing them on stakes have been adopted, but these are temporary cultivation methods and are not permanent. It is not a means of creating reefs. The present inventor has learned that marine gravel reefs and fish reefs are inseparable, and that something that has the functions of both is naturally useful for the cultivation of marine animals and plants.As a result of research, the present inventor developed the present invention. This will be explained below according to the drawings.
第１図は礁を構成する単位塊状体で、たとえば４０〜５
０聴径に破砕した高炉スラグであり、他に転炉滓や電気
炉滓等の鉱滓や自然石あるいは砕石、コンクリート屑な
どを用いることも出来る。Figure 1 shows the unit blocks that make up the reef, for example 40 to 5
This is blast furnace slag crushed to zero diameter, and other materials such as mine slag such as converter slag and electric furnace slag, natural stone or crushed stone, and concrete scraps can also be used.

通水性に富む塊となる。そこで第３図に示すようにＬ形

期間養生せしめると銅芯材７を包囲した礁８が出来る。When the aforementioned lump 1 is charged into a mixer or the like using a relatively small amount of cement and water and kneaded, a lump 1 as shown in Fig. 2 is obtained.
Cement sprinkled lumps 3 are formed on the surface of which a cement layer 2 is formed. These lumps 3 are fixed to each other through the cement layer 2, and the whole becomes a large lump like millet, and the surface is It becomes a mass with high water permeability, which is filled with irregularities and has multiple stages of voids 4. Therefore, as shown in FIG. 3, L-shaped frame plates 5a and 5b are stood upright on the bottom plate 6 at an appropriate interval, and a copper core material 7 is placed between them with an appropriate spacer. When the lumps 3 are charged using the same and allowed to cure for a predetermined period of time, a reef 8 surrounding the copper core material 7 is formed.

する。An annular fastening body 10, 12, 13, 14 having an annular head 9, 9a made of wire, fiber or plastic sticks as shown in FIGS. 5(a) to 5(d) is implanted. (b) is a concrete block that has been charged and fixed in advance to the concrete block body 11;
(C) is a wire with many annular heads formed, (d
) is a fastening annular body having a partially cut-off annular head 9a. This anchoring annular body can be embedded and installed in well-known fish reefs by embedding and adhesive, but the reason why it is easy to install and embed in the above-mentioned millet-shaped reef is because it is a block between the frame plates. This is because it is possible to insert and fix the body 3 during insertion.The heads of a large number of attachment annular bodies 15 protrude from the surface of the reef 16 in which the attachment annular bodies 15 (general term) are embedded. 8. As shown in FIG. 7, a short wire 17 to which germinated seaweed has been attached and penetrated is tied to the head of the anchoring annular body 15 and then thrown into a predetermined seabed. Useful seaweed 18 as shown in the figure grows in a short period of time and can be taken in.
1. Among the reefs 16, those fitted with steel core materials as shown in Figure 4, the protruding portions are joined by welding, bold fastening, joints, etc., similar to the joining means used for steel buildings. , it is easy to manufacture giant reefs, for example, reefs with a huge space of 20 m to 30,771 square meters, and because of their high mechanical strength, they are pre-assembled on land using a crane ship and transported offshore, as shown in Figure 9. It can be installed on the ocean floor. In other words, a huge seaweed/fish reef 16 is completed in a short period of time.
