【産業上の利用分野】本発明は、人工魚礁用、護岸用な
どとして使用するコンクリートブロックに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block used for artificial reefs, revetments and the like.
【０００２】[0002]
【従来技術と問題点】近年、ぶり、鯛、ひらめ等の高級
魚、昆布、わかめ等の海藻類及びそれらの海藻を食して
成育するうに、あわび等の魚介類に対しては、これらを
人工的に成育する、いわゆる「育てる漁業」が盛んにな
ってきた。[Prior Art and Problems] In recent years, high-quality fish such as yellowtail, sea bream, and flounder, seaweeds such as kelp and seaweed, and seafood such as abalone have been artificially grown to grow by eating these seaweeds. The so-called "breeding fishery" that grows naturally has become popular.
【０００３】この背景には、俗称「磯焼け」といわれ

計をたてている沿岸漁民にとっては、非常に大きな痛手
になっている。Behind this, there is a phenomenon in which seaweeds such as kelp and wakame seaweed disappear, which is commonly called "isoyoke". When this sea shore phenomenon occurs, seaweeds do not grow at all, even though the sea in the vicinity is clear and very beautiful.Therefore, sea urchins, abalone, mussels, and other schools of fish disappear. This is a huge pain for coastal fishermen who collect their livelihood and earn a living.

とに起因する、蛋白質、ミネラル等の栄養素の欠如。 といった原因が考えられている。By the way, although the scientific elucidation of the above-mentioned rock burning phenomenon is insufficient, it is now rather (1) felling trees and improving rivers, rather than the simple pollution of the coast and underwater that was said before. Due to such reasons, the water of the river, which was rich in trace minerals such as iron, phosphorus and magnesium, stopped flowing into the sea. (2) Underwater rocks are contaminated by elution of alkaline components, mainly calcium, contained in large amounts in tetrapods, revetment blocks, concrete blocks such as artificial fish reefs. (3) Lack of nutrients such as proteins and minerals due to the inability to dump a large amount of seafood debris collected for fisheries processing into the sea due to the Water Pollution Control Act. The cause is considered.
【０００５】これらのことから、「磯焼け」は、微量ミ
ネラルの不足、アルカリの溶出などといったことが大き
な原因になっている。From these things, "isoyaki" is largely caused by lack of trace minerals, elution of alkali, and the like.

功した。[0006] The inventors of the present invention have found that, by covering concrete blocks such as tetrapots and revetment blocks with natural ore of 100% mineral,
In addition to preventing elution of alkaline components centered on calcium, he succeeded in producing a concrete block that continues to bleed into the sea by using his own minerals as a nutrient source for seafood.
【０００７】従って、本発明の目的は、上記アルカリ分

ックの提案にある。Therefore, an object of the present invention is to propose a concrete block which does not worry about elution of the above-mentioned alkali content and continues to bleed in the sea by using its own mineral content as a nutrient source for seafood.

It is said that a resin layer was formed on the surface of the concrete block body by the natural graphite silica mixed resin and the long glass fiber.
