Benefits of technology

[0033] In the second and sixth inventions of the invention, since the central part of the base is constituted by a flat plate, the entire base can be reduced in weight. Further, since a plurality of stable legs are protruded from an outer peripheral edge of this flat plate, the structure, when being submerged into the sea to be disposed therein, can be stable. This flat plate and stable legs can be integrally formed of a steel material, concrete material, or the like.
[0034] In the third and seventh inventions of the invention, as described above, since the pillar bodies raised from the central part of the base and the pillar bodies raised from the peripheral part of the base are respectively mutually coupled through a frame which is coupled with the base, or since the respective pillar bodies are accommodated in a frame body which is fixed to the base, the respective pillar bodies can be attached to the base securely. Accordingly, in addition to making the...

Problems solved by technology

In the techniques of Japanese Patent Nos. 2824232 and 2905432, since the carrying bases to which seaweed species fungi are allowed to adhere in advance have to be attached and fixed to the pillar bodies and to the stick-like bodies, respectively, in a branching manner, problems arise in that the workability is extremely poor and that the cost becomes high.
Further, in the technique of JP-A No. 2000-69878, since seaweed species fungi have to be planted on the pillar body standing at the central portion of the concrete base formed into the cross-shape by a predetermined means, similarly to Japanese Patent Nos. 2824232 and 2905432, problems arise in that the work is complicated and that the cost becomes high.
The technique of JP-A No. 2000-69878 has problems that the plurality of special pillar bodies independently standing by buoyancy have to be employed, that the lower ends of these pillar bodies have to be swingably attached and fixed to the base made of stone, employing the extremely complicated coupling means, that the structure thereof is comple...

first embodiment

[0048] Referring to FIGS. 1 to 3, a marine forest structure according to the invention will be described. This marine forest structure 1 is basically composed of a base 2 and a plurality of pillar bodies 3 raised from this base 2.

[0049] The base 2 is composed of a rectangular flat plate 4 formed of steel, concrete, or the like and legs 5 protruding from respective corners of this flat plate 4. These legs 5 are formed integrally with the flat plate 4 in advance. These legs 5 plays a role of making the base 2 stable on the bottom of the sea when the marine forest structure 1 is submerged and placed in the sea.

[0050] Holes 6 for raising the pillar bodies 3 respectively are provided in a central part A (central part of the base) and corner parts B (peripheral parts of the base) of the flat plate 4. In the present embodiment, four holes 6 are provided in the central part of the flat plate 4, and one hole 6 is provided on each corner part.

[0051] Steel, concrete, telegraph poles which ha...

second embodiment

[0056] In this second embodiment, pillar bodies 3a raised from the central part of the base 2 have a height of approximately 12 m, and pillar bodies 3b approximately 4 m. Accordingly, the entire height of the marine forest structure 9 is approximately 12.5 m, the bottom side width approximately 12 m, the space volume approximately 330 m3, and the entire weight approximately 36.7 t. This marine forest structure 9 can be effectively employed in a sea area which has a deep depth.

[0057] Referring to FIGS. 5 to 7, a marine forest structure 10 of the third embodiment according to the invention will be described. Although scrap telegraph poles are effectively utilized for the pillar bodies 3 in the above-described first and second embodiments, in the marine forest structure 10 of this third embodiment, thinning wood of mountains and forests is effectively utilized instead of scrap telegraph poles.

third embodiment

[0058] In describing the marine forest structure 10 of the third embodiment with reference to the drawing, pillar bodies 11a are thinning wood whose height is approximately 12 m, and pillar bodies 11b are thinning wood whose height is approximately 4 m. A plurality of pillar bodies 11a are respectively raised from four holes 6 of a central part A (central part of the base) of a flat plate 4 of a base 2, and pillar bodies 11b are raised from holes 6 of corner parts B (peripheral parts of the base) of the flat plate 4. The pillar body 11a raised from the central part A can be constructed by coupling the pillar bodies 11b which has a low height.

[0059] Although the number of pillar bodies 11a, 11b raised from the respective holes 6 changes depending on the diameters of the pillar bodies, generally approximately four to twelve pillar bodies 11a, 11b can be inserted into the respective holes 6 to be raised therefrom. The positions of the lower end portions of the plural pillar bodies 11a,...

Abstract

The present invention is to provide a marine forest structure by which many kinds of fishes and shellfishes can gather and inhabit and to which useful seaweeds such as of Laminariaceae and the like can adhere to propagate when the structure is submerged and disposed on the bottom of the sea. Provided is a marine forest structure 1 which is composed of a base 2 in which legs 5 are protruded from a peripheral edge of a flat plate 4 in which plural holes 6 are provided in a central part and a peripheral part thereof and two kinds of pillar bodies 3a, 3b whose lengths are different. The marine forest structure is constructed such that a plurality of pillar bodies 3a which has a predetermined height are raised from and fixed to the holes 6 of the flat plate 4 and that pillar bodies 3b which has a height lower than that of the pillar bodies 3a with the predetermined height are raised from and fixed to the plural holes 6 of the periphery of the flat plate 4.
