Abstract

PURPOSE:To commonly use a hollow body for both wave dissipation and fish nest and use also for water purification by forming the uppart of the hollow body in a semi-spherical shape in the hollow body providing a large number of through-holes in the surface thereof. CONSTITUTION:A permanent block body constituted of a semi-spherical upper block body A and a cylindrical lower block body B is installed at the sea bed. In the case of wave dissipation, the upper part of the upper block body A is so placed that it reaches near the water surface or that it projects slightly upward from the water surface. The force of waves is lessened by the sphere to dissipate waves. While, in the case it is used for a fish nest, the permanent block body is so placed that it is submerged into the sea. Small fish is made to freely enter from a plurality of through-holes 2. In addition, water purified agents 4 such as charcoal, ceramic, etc., are placed in the permanent block, and impurities, etc., into the sea are removed. According to the constitution, the permanent block body is used for both wave dissipation and fish nest.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose block body for use in wave breaking, fish reef, water purification in the sea, rivers, lakes and marshes.

[0002]

2. Description of the Related Art Conventionally, wave-dissipating blocks and artificial fish reefs have been used in the sea, rivers, etc., but their structures are different depending on their respective purposes, and no single product can be used in various ways.

[0003]

Conventionally, a wave-dissipating block has been used for the purpose of protecting the coast and the like, and a tetrapot having a plurality of convex portions is an example thereof. In addition, so-called artificial fish reefs are used in which various materials are submerged on the seabed to form a ridge for the purpose of creating a habitat for aquatic life. This aims to artificially grow organisms by utilizing the property of fish gathering on a bank or rocky reef protruding to the sea floor, and sunk concrete blocks, earth pipes, abandoned ships, and aged vehicles on the sea floor. However, the structure and shape of the wave-dissipating block for canceling the waves that hit the shore and the artificial fish reef for the purpose of cultivating living things are different, and the wave-dissipating block is mainly made of concrete. On the other hand, the artificial fish reef uses various materials and is not a structure that can be shared by a single article, so it lacks versatility and is disadvantageous in terms of manufacturing and cost. And, recently, the deterioration of water quality due to industrial wastewater and the like has been remarkable, and at present, there is no effective water purification product that can be submerged in water. The present invention has been invented with the object of providing a multipurpose block body that enables common use of the above-mentioned conventional wave-dissipating / fish reef blocks and can also be used for purification of water quality.

[0004]

As means for solving the above-mentioned problems, the present invention has a structure in which a large number of holes are provided in a block body having an upper portion formed in a spherical shape. That is, in the hollow body having a large number of through holes formed on its surface, the upper portion of the hollow body is formed in a hemispherical shape. The present invention is a multipurpose block body having the above structure.

[0005]

In order to use the present invention, the block body is installed on the bottom of the water. When breaking the waves, install the upper part of the block so that it is close to the water surface or slightly above the water surface. Since the upper part of the block body is a spherical surface, the wave force can be relaxed and the wave can be extinguished. When using it as a fish reef, put a block body so that it is submerged in water. A plurality of through holes are provided on the surface of the block body, and small fish and the like can freely enter and leave through these holes, and can serve as a fish reef.
As shown in the examples below, when a water purification agent such as charcoal or ceramic is placed in the block body, impurities, pigments, odors, etc. in the water can be removed by the adsorption action of these substances. it can. When used for a long period of time, algae and the like adhere to the periphery of these purifying agents, and fish can be eaten by the algae.

[0006]

EXAMPLES Examples of the present invention will be described below. (B) Forming a hemispherical hollow body with concrete,
A step portion (1) is provided in the lower portion, a plurality of through holes (2) are provided in the hemispherical portion of the hollow body, and the upper block body (A) having the above configuration is provided. (B) A bottomed cylindrical body having an inner diameter into which a step can be inserted is formed, and a plurality of through holes (2) are provided on the outer peripheral surface of the cylindrical body, and the lower block body (B) having the above configuration is formed. Set up. (C) A water purifying agent (4) is provided by containing an adsorbing substance made of charcoal inside a mesh bag body (3) having an appropriate mesh. (D) A water purification agent is stored in the lower block body, and the upper block body is inserted and locked onto the upper portion of the lower block body. The above is one embodiment of the present invention.

In this example, the block body is divided into an upper portion and a lower portion to facilitate transportation. In addition, the thickness of the stepped portion of the upper block body and the wall thickness of the lower block body are made substantially equal to each other to improve durability. The water purification agent is stored in the lower block body and then the upper block body is mounted, but depending on the situation, the purification agent may be replaced every few years. In the present invention, the block body thickness and the hole diameter are important, and a thickness of 20 cm or more and a hole diameter of about 15 cm are required in terms of durability and safety. It is easy to use charcoal as well as ceramics as the purifying agent. It is recommended to put it in a nylon net and put it in about half the volume of the lower block. INDUSTRIAL APPLICABILITY Since the present invention has a spherical upper portion, it has an excellent appearance and can be used for various purposes such as wave-dissipation, fish reef, and water purification.

[0008]

According to the present invention, since an upper hemispherical block body having a large number of holes is used, it can be used for both wave-dissipating and fish reef, and if a water purification agent is stored in the block body, It is possible to obtain a useful block body that is useful for purification and environmental protection. Further, since it is only necessary to manufacture an article having one shape, it is possible to provide a block body which is advantageous in terms of cost.
