のである。DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention is directed to the protection of useful algae and organisms related to them by sinking the seabed to a seabed suitable for creating a seaweed bed and allowing algae to propagate on its surface. This is related to reef blocks for cultivating etc.
（ロ）従来の技術
従来この種のブロックは単純なブロック材の表面に水溶
性薬品の粒子を吹き付は塗布したり、腐食コンクリート

面の形成を行ったものを用いてきた。(B) Conventional technology Conventionally, this type of block was made by spraying particles of water-soluble chemicals on the surface of a simple block material, or by forming a surface layer of corroded concrete, making it difficult for algae seeds to adhere to the surface. We have been using materials whose surfaces have been formed.
（ハ）発明が解決しようとする問題点

見られた。(c) Problems to be solved by the invention Since the surface of conventional reef blocks is integrally fixed with the core material, useful algae that have grown on the surface of the reef blocks will wither after 4 to 5 years after being immersed in seawater.・There have been many cases in which, after a spill, unneeded species such as limestone breed and become the dominant species, making it impossible for other useful species, algae, to attach or grow.

作り出すようにしたものである。(d) Means for Solving the Problems In order to solve the above problems, the present invention forms a salt-containing concrete layer that utilizes the heat-generating expansion of iron due to the action of salt contained in seawater, and immerses it in seawater. After a certain period of time passes, the surface layer of the reef bronc tends to peel off.
This is designed to activate the adhesion surface by constantly exposing new surfaces. In addition, the surface layer is immersed in seawater, which causes cracks and natural collapse areas, so the surface layer is made uneven, creating a condition to which seeds of useful species can easily adhere.
（ホ）実施例 以下図面に従って本発明の詳細な説明する。(e) Examples The present invention will be described in detail below with reference to the drawings.
１は芯材で表面を鉄網２によって被覆されその表部に塩

３が形成されている。この表皮層３は図面に示すように
芯材の上に何層かを積層し、状況に応じて含有される塩
分の量を調整して、剥離時期を沈設場所の状況に合わせ
て調整することにより、一定時期毎に次々と表皮層が剥
離し易くなるように構成する。Reference numeral 1 denotes a core material, the surface of which is covered with a steel mesh 2, and a skin layer 3 made of concrete containing salt is formed on the surface thereof. As shown in the drawing, several layers of this skin layer 3 are laminated on top of the core material, and the amount of salt contained in the skin layer 3 is adjusted according to the situation, so that the time of peeling is adjusted according to the situation of the place where it is deposited. Accordingly, the structure is such that the epidermal layers are easily peeled off one after another at regular intervals.
尚、表皮層を一層だけしか設けなくとも良いことは勿論
である。Of course, it is also possible to provide only one skin layer.
（へ）発明の作用及び効果
本発明は以上のように構成したので、これを海中に浸漬
すると主としてコンクリートに含有させた塩分の作用に
よって、表皮層３にひび割れや吸水現象が生じ、徐々に
海水が内部に浸透して、やがて鉄網２の部分に達する。(f) Functions and Effects of the Invention Since the present invention is constructed as described above, when it is immersed in the sea, cracks and water absorption phenomena occur in the skin layer 3 mainly due to the action of the salt contained in the concrete, and the seawater gradually absorbs water. penetrates into the interior and eventually reaches the part of the iron mesh 2.
鉄は主として海水の作用によって錆びて発熱膨張するか
ら、先ず最表部の表皮層が鉄網の錆に内部から押されて
剥がれやすくなり、次の表皮層３が現われる。そして次
の表皮層３のコンクリート中の塩分が主として作用を開
始し、順次表面部の更新が行なわれるものである。Since iron rusts mainly due to the action of seawater and expands due to heat generation, first the outermost skin layer is pushed from inside by the rust of the iron mesh and tends to peel off, and the next skin layer 3 appears. Then, the salt in the concrete of the next skin layer 3 starts to act, and the surface area is sequentially renewed.
これにより、藻類付着面の活性化を図る一方、表皮層を
構成するコンクリート中の含有塩分の吸水作用によって
発生する自壊作用により礁表面を有用藻類の種子が付着
し易い状態を作り出す。While this aims to activate the algae adhesion surface, it also creates a state in which the seeds of useful algae can easily adhere to the reef surface due to the self-destructive action that occurs due to the water absorption effect of the salt content in the concrete that makes up the skin layer.
以上のように本発明は塩分の吸水作用と鉄の発錆作用を
利用して表皮層の自動的な更新を行うもので、藻場礁は
勿論魚礁としても利用でき幅広い応用範囲をもつもので
ある。As described above, the present invention automatically renews the skin layer by utilizing the water absorption effect of salt and the rusting effect of iron, and can be used not only as a seaweed bed reef but also as a fish reef, and has a wide range of applications. be.
