BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial reef effectively utilizing shells that become industrial waste.

2. Description of the Related Art Various types of artificial artificial reefs made of concrete that have a shape satisfying the habitat conditions of fish and shellfish and seaweed are known, and are submerged to a certain depth in which the amount of dissolved oxygen is large.

[0003] However, in the conventional artificial reef, the surface of the concrete block is a flat surface or an arc surface, and similarly, the internal cavity is cylindrical or spherical.
In any case, since it has a monotonous and regular shape that is too well-regulated due to restrictions on mass production, it is difficult for fish and shellfish and seaweed to collect and inhabit due to its weak alkalinity.

[0004] For example, if the surface of the concrete block is uniform, spores of seaweed are less likely to adhere and the roots do not prosper. In that sense, fishing reefs naturally made from steel fragments of a ruined ship that sank on the sea floor are more suitable habitats for various fish and shellfish and seaweeds. That said, it is difficult for artificial mass production methods to obtain reefs suitable for all types of aquatic products.

As is clear from the partially enlarged view of FIG. Not only does the surface present an at-random uneven rough surface, but also in the interior, many openings are distributed as voids (O) between adjacent particles. As a result, during installation and use in the sea as an artificial reef, the pores (O) exhibit water permeability, and extremely large numbers of spores of seaweed adhere to and prosper to the irregular surface and the internal void (O).

In the illustrated example, the base frame (13) of the mounting table (B) is formed in a rectangular shape, but the shell shell (A) is inserted into the channel groove (G) of the rail support (14). As far as possible, the base frame (13) may be frame-integrated into a plane shape other than a square, and the rail support (14) of the mounting table (B) may be suggested in the partially modified embodiment of FIG. Even if it is erected from the base frame (13) in an inclined installation state, it may be acceptable.

In any case, since the shell molded body (A) is adapted to be freely inserted into and removed from the rail support (14) of the mounting table (B), the artificial reef is pulled up from the sea, It is possible to collect seaweeds adhered and proliferated on the shell-shaped body (A) collectively on land, and that the shell-shaped body (A) weathers with time and gradually collapses from its surface. However, this can be exchanged for a new one on land, and the convenience of transportation to the installation location and handling work is enhanced.

Further, the mounting table (B) for the shell molded body of the second embodiment is the same as the mounting table (B) shown in the first embodiment.
In the same manner as the base frame (13), a hollow rectangular steel material is integrated into a polygonal planar shape. Reference numeral (17) denotes a large number of core rod receiving holes which are distributed in the installation table (B) and into which the core rod (16) for mounting the shell molded body (A) is inserted so as to be able to be pulled out and inserted again from above. Thus, an artificial reef as shown in FIG. 8 is completed. According to this, since the shell molded body (A) has a columnar shape, the flow resistance of seawater can be suppressed to a small value, which is useful for improving its durability.

As described above, in the artificial reef of the present invention, silica obtained by a reaction between sodium silicate and sulfuric acid due to its constitution is kneaded with a synthetic resin curable by a curing agent, A polymer binder (11) prepared to have an appropriate constant viscosity and a pulverized product of various shells (10) are kneaded and molded into a flat shell-shaped molded product (A) by a mold (12).
In addition to being molded and solidified, the mounting base (B) for the shell molded body in the sea is a polygonal base frame (1) made of hollow square steel.
3) and a channel support (1) made of channel-shaped steel members which are assembled as a pair facing each other from the base frame (13).
4), and the shell molded bodies (A) are freely inserted into and removed from each other between the rail supports (14) of the mounting table (B). The technical problem can be surely improved, and there is an effect that it can be provided as an artificial reef rich in attracting various fish and shellfishes and seaweeds.

In particular, since the shell formed body (A) of the artificial fishing reef is made of crushed shells (10), shells that become industrial waste are effectively used, and artificial shells that are not uncomfortable for fish and shellfish and seaweeds. The reefs can be mass-produced inexpensively, and in addition to exhibiting an at-random uneven rough surface, the block is solidified by binding with a special polymer binder (11). Since the voids (O) are distributed in the openings, there is an effect that spores of seaweeds can be attached and proliferated extremely reliably.

Furthermore, if the structure according to the fourth aspect is adopted, the ceramic ball (18) can also exert the action of purifying seawater, and the shell molded body (A) is originally a marine organism. Combined with the use of certain shells as aggregate, there is an effect that it can be provided as an artificial reef excellent in compatibility with the natural environment.
