Description

[Detailed description of the invention]

[0001]

[Technical field to which the present invention belongs]

 The present invention relates to a modular artificial fish reef using waste concrete utility poles (hereinafter referred to as “con pillars”) laid on the sea floor or the like.

[0002]

[Prior art]

 Conventionally, there has been a proposal of an assembling type artificial reef using a con pillar as a constituent element. This type of artificial reef has the advantage of the material that the con pillars are pipes (hollow rods), which can be handled alone, and the construction of a self-sustaining heavy structure by assembling and sinking three-dimensionally. Has the advantage of In addition, the economic effect is high in terms of effective use of waste materials.

[0003] An overview of the prior art is disclosed in, for example, Japanese Patent Application Laid-Open No. 55-42575, which discloses a three-dimensional structure in which con columns are assembled in a cross-girder shape.

[0004] Japanese Patent Application Laid-Open No. Hei 8-289694 discloses a three-dimensional structure in which con columns are assembled in a checkerboard shape via supporting columns and stacked.

Further, in Japanese Utility Model Publication No. 59-20047, a beam member is assembled to form an outer structure, a utility pole is mounted between opposing beam members, and the utility pole and the beam member are connected to each other on the beam member. There is disclosed a three-dimensional structure that is more connected to enhance durability.

[0006] All of these conventional configurations use a connecting member, a support, a beam member (or a wall-shaped member), and form a box-shaped frame structure to secure installation stability. It is trying to do it.

[0007]

[Problems to be solved by the invention]

 However, according to the research and research conducted by the inventor, although it does not deny the above-mentioned prior art, it is not necessary to request a solid frame structure in which fixing means (support means) is an essential component with respect to installation stability. And almost completely filled with the weight of the stacked columns.

In addition, there is no need to be particular about forming a box-shaped frame structure.

Therefore, it is preferable to construct fish reefs of various shapes (structures) according to the installation environment.

[0010] For that purpose, it is considered that a con pillar is optimal as a component capable of flexibly responding to a design change.

The present invention has been made in view of such circumstances, and provides an assembling artificial reef which solves the above-mentioned problems and has improved gathering (fish collecting) effects, economic effects, recycling effects, and the like. is there.

[0012]

[Means for Solving the Problems]

 In order to solve the problem, the present invention is an improvement of an assembling artificial fish reef using con pillars laid on the sea floor, etc. It is characterized in that it has a substantially prismatic self-solid body having a watermark structure.

[0013] The second invention is characterized in that the con columns are laminated with a beam member or a sleeper member interposed therebetween to form a substantially box-shaped self-solid body having a watermark structure. It is a thing.

Further, the third invention is characterized in that a three-dimensional structure having a void portion is constructed by randomly stacking columns in a region of several tens of meters square.

[0015]

[Embodiment of the invention]

 In the embodiment of the first invention, in the above-described configuration, the self-solid body is formed into a substantially quadrangular prism shape or a substantially quadrangular prism shape.

Further, in the embodiment of the second invention, in the above configuration, the beam member or the sleeper member is arranged to face each other, and a plurality of connecting columns are bridged between the members.

[0017]

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an external view of an assembled artificial reef showing an embodiment according to the first invention.

As shown in the figure, the prefabricated artificial reef (X) of the present invention is obtained by stacking a plurality of columns (1), each of which has been appropriately sheared, into a substantially triangular prism-shaped self-solid body having a watermark structure. Has been established.

Here, the length of the connecting post (1) is 3 m, and the three connecting posts (1) are stacked one on another as sides of a triangle. The height of the three-dimensional stacked solid body is about 1.9 m, the volume is 7.4 m ³ , and the weight is about 3 t. The top column (1) is fixed to the bolt (2) at the intersection with the lower column.

FIG. 2 is an external view of an assembled fish reef showing another embodiment of the present invention.

As shown in the figure, the assembled artificial reef (X ′) of the present invention is obtained by stacking a plurality of columns (1) that have been appropriately sheared into a rectangular shape, and having a roughly square pillar shape having a watermark structure. It has its own solid body.

Here, the length of the connecting post (1) is 3 m, and three connecting posts (1) are stacked on each side of a square. The height of the ^three- dimensional stacked solid body is about 2.1 m, the volume is 18.9 m ³ , and the weight is about 5 t. Becomes The top column (1) is fixed by bolts (2) at the intersection with the lower column.

FIG. 3 is an external view of an assembled artificial reef showing an embodiment according to the second invention.

As shown in the drawing, the artificial fish reef (Y) of the present invention is constructed by laminating a pair of con pillars (1) with a beam member or a sleeper member (3) interposed therebetween to form a schematic box having an openwork structure. The body has its own solid body.

Here, the connecting column (1) is used in its original form (12 m to 15 m), and a beam member or a sleeper member (3) is arranged to face each other, and a plurality of members (3) are provided between the members (3). The column (1) is to be crossed. The shape of the three-dimensional self-solid is 3.5 m (width) x 12. It is about 0 to 15.0 m (length) × 3.58 m (height). Both ends of the beam member or the sleeper member (3) are fixed by through bolts (4) at both ends.

FIG. 4 is an external view of an assembled artificial reef showing an embodiment of the third invention.

[0028] As shown in the figure, the assembled artificial reef (Z) of the present invention constructs a three-dimensional structure having voids by randomly stacking the con pillars (1) in an area of several tens of square meters. ing.

Here, the column (1) is used as it is (12 m to 15 m), and several tens of them are piled up at random in an area of 20 to 30 m × 40 to 50 m square.

After installing the various reefs of the present invention in the southeastern part of Yamaguchi Prefecture (Seto Inland Sea; water depth of about 30 m), a follow-up survey (several times in about two years) was conducted to assemble (fish) and to improve the durability of the reef.・ Evaluation of installation stability, etc. showed that the collection and fish collection effects tended to increase and become fixed both in type and quantity at each survey, although there were seasonal fluctuations and environmental fluctuations such as weather and sea conditions. The durability and installation stability of the reefs were good with no damage, deformation, erosion, burial, etc., observed.

[0031]

[Effect of the invention]

 The present invention has the above-mentioned structure, and according to this, the artificial pillared reef can be formed by reusing the waste con columns, so that it is inexpensive and easy to construct. It can be expected that the project (fish production) effect on cost will be improved.

In addition, there is a recycling effect in terms of effective use of resources, and it is possible to contribute to the local community as a power company.
