Abstract

<P>PROBLEM TO BE SOLVED: To retard expansion of bamboo groves and restore fishery resources based on the fact that rich seaweeds and a large-scale fish bank to assist the growth of fries and young fishes are necessary for restoring fishery resources exhausted by change of global environment and over-fishing of the resources and that forest destructed by bamboo damage is a remote cause of the exhaustion of fishery resources. <P>SOLUTION: The fish bank is a standing fish bank produced by using a large quantity of bamboo materials in a vertical direction. The installation of the fish bank develops a solid article comprising small spaces and a natural material near the sea surface, forms habitats of small fishes and microorganisms, grows seaweeds on the bamboo material in a shallow water environment, proliferates the microorganisms and completes a food chain to restore fishery resources. The forest released from bamboo damages is revived by activating photosynthesis, and eventually supplies nutrient salts to the sea to form a remote cause of the restoration of fishery resources. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention cuts down a ruined bamboo forest and a bamboo forest that destroys the forest with vigorous fertility, bundles the bamboo material for the purpose of effectively using the waste bamboo material, and creates a bamboo reef using the bamboo material bundle in the standing direction It relates to the restoration of fishery resources by breeding seaweed and microorganisms to complete the food chain.

  Conventional fishing reefs are often made of concrete, plastic, thinned wood, iron, or a combination of them, and are expensive, or some are for the purpose of recycling waste tires, ships, etc. There are many artificial structures that are difficult for microorganisms to land on, and quadrangular pyramid reefs that combine bamboo and thinned logs are mostly based on the concept of land, and decomposition of microorganisms is not considered.

Although fishery resources are depleted, there are various problems such as global changes due to an increase in carbon dioxide, overfishing due to evolution of fishing methods, and environmental destruction due to the cultivation of specific fish species. The impact of this is great, and it has been devastated by the impact of landfills, industrial wastewater and domestic wastewater.
The problem to be solved by the present invention is, in short, the restoration of fishery resources in coastal seas and lakes, but in the background is the restoration of orchards, fields and forests that have been eroded by Mosouchiku, Hachiku, Madake, etc. Therefore, the restoration of healthy forests leads to the permanent resurgence of fishery resources, and there is a parallel problem of quantitative disposal of the enormous amount of waste bamboo.
Therefore, the method of using bamboo is not effective unless it is used for mass consumption, and the use of large-scale waste bamboo with low cost and continuity is an issue.

Japan's coastal waters where many seaweeds, such as kombu, wakame, arame, kajime, and hondawala, were prosperous, were supported by the rich forests behind them.
Now that rich hardwood has turned into an oligotrophic artificial coniferous forest, the artificial forest has been devastated due to sluggish timber prices, and is further transformed into an oligotrophic bamboo forest, and is also affected by landfills, etc. Sediment flows in, vertical revetment works destroy natural shallow waters, seaweeds are devastated and coastal fisheries are severely hit.
Even in subtropical waters, the coral reefs that died due to the abnormal breeding of the giant starfish, or the coral reefs that died due to the inflow of red soil and rising sea water temperature, disappeared immediately next to the coral reef where many kinds of creatures flock. The sea desert is spreading.
The decrease in seaweed and coral reefs naturally depletes fish that lay eggs only on seaweed, and fish that feed on microorganisms grown by seaweed, and the resurgence of fishery resources has the problem of reviving this disrupted food chain.

Used or obsolete fiber-reinforced plastic ships, commonly known as FRP ships, are lightweight, high-strength, and highly durable. Since it is moored at the port, it is difficult to collect, transport, and dismantle, and effective recycling technology has not been established.
In addition to abandoned boats that are estimated to be 140,000 ships, which have become a major social problem, the number of ships exceeding 10,000 ships will be abandoned every year. Therefore, inexpensive and effective recycling technologies and reuse methods are desired.

  Bamboo fishing reefs that use bamboo bundles in the vertical direction are broken down by beetles and microorganisms and are damaged in units of 1 to several years. Therefore, it is necessary to constantly replace new bamboo. Means are a challenge.

In the past, the bamboo forest damage was just a matter of extending the rhizomes to advance to the adjacent land, but the current bamboo forest damage is a few bamboos that suddenly appeared on the borders of grassland or roads, etc., grow in spring or two months Covering the sky of the trees, the underground stems stretched vertically and horizontally strangle the roots of the trees, instantly transform into a bamboo forest while destroying the forest, terraced rice fields, tea plantations, orchards, and even wild animals can enter It has been transformed into a bamboo tree with no yellow fade.
Although it is still an event near Satoyama, it has advanced to the depths of the mountains a few years away, and it is fully predicted that forests throughout Japan will become unrenewable in the near future, and prompt measures are being taken. Imminent.
The sea lives only when there is a rich forest, and the restoration of the forest that leads to the regeneration of the sea is an important parallel issue of the present invention.

Bamboo damage countermeasures are enormous, and permanent countermeasures are required for many years, but the present invention does not produce waste by bamboo reefs that need to be regenerated every one to several years, and is effective on a large scale Provide a solution.

  The present invention is a bamboo reef that uses a bamboo bundle in the standing direction, and the frame and the bamboo can be joined and separated repeatedly, and the bamboo bundle with the lower part fixed to the frame has a standing posture in the water. Bamboo fishing reef characterized by maintaining, creating a shallow sea state consisting of solid organic matter under the sea surface of about 8m or more where the arrival of sunlight is scarce, promoting the implantation of microorganisms and providing the starting point of the food chain .

  The bamboo material bundle of the present invention is a bamboo reef characterized by using bamboo material obtained by dividing a bamboo main trunk portion in the vertical direction and bundling bamboo material cut into an arbitrary length into a bamboo material bundle. I will provide a.

The frame body for fixing the lower part of the bamboo bundle according to the present invention is a frame body made of concrete, plastic, iron alone or a mixture thereof, or a frame body made of a hull of a fiber reinforced plastic ship. Provide bamboo reefs.
The shallow and flat Japanese boats and open boats, etc. of the so-called FRP abandoned boat used in the present invention have a short depth of about 3 m to fix a long bamboo material. It is advantageous to use it in freshwater lakes or brackish lakes that are less affected by tides and waves.

  The bamboo reef where the frame of the present invention and the bamboo bundle can be repeatedly joined and separated, the lower part of the bamboo bundle is inserted into the frame, and sand, earth, pebbles, concrete pieces, ceramic pieces, iron pieces are inserted from above. Fill with at least one kind of aggregate and fix it by applying vibration while adding water, making use of the unevenness of bamboo, or fixing it to the frame using a rope or wire tie, and filling the above A bamboo reef characterized in that a bamboo bundle is separated from the frame body by removing objects and binding tools, and provides a joining method in which the above-mentioned materials can be reused without generating waste when regenerating the reef. .

Provide bamboo fishing reef that reinforces the resistance to tidal and water pressure and guides in harmony with water current.

  The bamboo material bundle of the present invention provides a bamboo reef characterized by consisting of a single material of bamboo, a mixture of bamboo and thinned wood, a mixture of bamboo and building waste wood, or a mixture of bamboo and iron.

The present invention relates to a large amount of waste bamboo that cannot be processed by conventional small-scale demand, and there is no place, area, or volume for processing this enormous amount on land, and the coastal sea area that is the only space It was an invention that found its way into the sea and lakes.
Unlike the northern sea area where huge kelp and other areas grow, Honshu's inner bay and the inner sea area have many flat seabeds where only a few seaweeds are laid, and here we make bamboo reefs using bamboo in the standing direction. There is a big meaning.
That is, the present invention in which a large amount of waste bamboo material is utilized in the vertical direction as it exists on land is to reconstruct the sea area of approximately 3 m to 25 m where the amount of transmitted sunlight is reduced to any shallow sea environment. , Organic solids with a large surface area appear near the sea surface to grow abundant microbial communities, promote the implantation of seaweed, and many small spaces appear three-dimensionally to ensure the safety of fry and larvae, Plankton->fry->juvenile-> eventually, complete the food chain to adult fish, and have the effect of reviving true fishery resources by leaving many fishes.
The same applies to lakes.

Bamboo fishing reefs that use bamboo timber bundles installed in the sea in the vertical direction are decomposed by microorganisms or must be exchanged and regenerated every one to several years by diet of aquatic organisms. It was a simple food chain itself, and it completed an inexpensive fishing reef and a simple exchange system.
The bamboo reef using the bamboo bundle of the present invention in the standing direction is characterized in that the frame body and the bamboo bundle can be repeatedly joined and separated, and the mountain sand etc. for fixing the bamboo portion is reused Since the reef is regenerated by exchanging only bamboo material on the sea surface where the reef is installed, it is a reasonable and inexpensive means of replacement and regeneration.

Fiber-reinforced plastic ships, commonly known as FRP ships, are estimated to be 140,000 abandoned boats, and more than 10,000 ships are being abandoned every year. However, the product is large and can be collected, transported and dismantled. Because of the difficulty, effective recycling and reuse technologies are eagerly desired.
Reusing an FRP abandoned ship as a frame is the simplest reuse that makes the best use of the excellent product characteristics. Both the production cost of the new frame and the processing cost of the FRP abandoned ship have been reduced. It is utility.

In fishing reefs using FRP abandoned ships, Japanese boats and open boats with shallow and flat hulls are not suitable for coastal waters where the influence of tides and waves is large due to insufficient depth to secure long bamboo materials. However, it is an effective means in shallow lakes where there is no fluctuation in water level and the influence of waves is small.
It must be saved from extinction by promoting the growth of aquatic plants and phytoplankton, breeding native fish species, and providing a home to protect themselves against alien meat fish.

The current damage to bamboo forests has quickly been destroyed and transformed into yellow bamboo forests.
When entering into the ruined bamboo forest, the stone walls built by the predecessors for the former terraced rice fields, orchards, and tea plantations are exposed to the unreserved appearance, but now it is green even if it is impossible by cutting the bamboo forest There is a little chance of reviving into the forest.
In the era when rivers were in a natural state, if abundant forest resources were restored, drowning in coastal waters could be prevented, but now many dams have been built in the rivers, and organic matter from the mountains to the sea has been built. Circulation is blocked.
The present invention activates the food chain such as beetle beetle → coral → fish by supplementing the circulation of organic matter blocked by providing a large amount of waste bamboo to the ocean and providing a large amount of food for microorganisms and aquatic organisms. It is an invention that contributes to the revival of fishery resources.

Bamboo material bundles are obtained by dividing a bamboo material from which some or all of the branches have been cut off in the vertical direction, and tying them in fixed units and placing them on a transport ship.
The frame is molded from concrete and placed on a transport ship.
Alternatively, the frame body using the FRP abandoned ship removes the propulsion device, the steering device, the deck, etc., closes the hole generated for that purpose, and tows to the installation area.
Other assembly parts such as plastic pipes, floats, and ropes are placed on a transport ship.
The earth and sand used to fix the bamboo to the frame is the mountain sand produced in the quarry and placed on a transport ship.
In the sea area where the reef is set up, the work facility ship is the center, and the above-mentioned transport ships gather around it, assemble on board or on the sea, and set as a vertical fishing reef using bamboo material in an upright direction by sinking to the seabed.
