Description

本発明は、繊維強化プラスチック船舶の鉛直方向上方に筒状の外枠を形成し、外枠に浮力付与手段を取付け、外枠内部の空間に個体の植物性有機物を挿入した浮沈式の有機物漁礁及び有機物漁礁集合体に関する。   The present invention relates to a floating and sinking organic reef in which a tubular outer frame is formed vertically above a fiber-reinforced plastic ship, buoyancy imparting means is attached to the outer frame, and individual plant organic matter is inserted into the space inside the outer frame. And organic matter reef aggregates.

例えば、棒状或いは索状の材料を用いて籠状に形成した枠体中に、間伐材や木材チップを含む林産物をネット状の袋に収納し、魚類の餌となる生物の育成増殖を図り、海藻類の付着育成を図り、魚類の定着育成を図る技術があるが、林産物をネット状の袋に入れ、海中に設置した籠状に形成した枠体中に入れるだけである。
間伐材などの林産物を再生する手段は、海中設置用構造体を引上げる方法であり、膨大な費用が必要である(例えば特許文献1参照)。
For example, in a frame formed in a rod shape using rod-like or cord-like material, forest products including thinned wood and wood chips are stored in a net-like bag, aiming to grow and proliferate organisms that become fish food, Although there is a technique to promote the growth of seaweeds by attaching and growing fish, it is only necessary to put forest products in a net-like bag and put it in a frame that is formed in the shape of a cage installed in the sea.
A means for regenerating forest products such as thinned wood is a method of pulling up a structure for installation in the sea, and enormous costs are required (for example, see Patent Document 1).

例えば、圧気供給機と浮力体を連結して気体量を調節する開放型浮力体によって、或いは密閉型浮力体によって浮沈機能を持たせた養殖用生け簀装置があるが、定型の生け簀を浮沈させる為だけの装置であり、中古或いは廃FRP船の有効利用を図り、伸縮する筒状の外枠を浮沈させ、有機物の再生、挿入を容易にした本発明とは異なる(例えば特許文献2参照)。   For example, there are aquaculture cages that have an ups and downs function by using an open type buoyant body that adjusts the amount of gas by connecting a pressurized air feeder and a buoyant body, or a closed type buoyancy body. The present invention is different from the present invention in which the used or waste FRP ship is effectively used, and the expanding and contracting cylindrical outer frame is floated and the organic matter is easily regenerated and inserted (see, for example, Patent Document 2).

特開2008−048687号JP 2008-048687 A 特開平11−178472号JP-A-11-178472

特許文献1に記載した背景技術では、間伐材等の林産物をネット状の袋に収納し魚類の定着育成を図る技術があるが、その食物連鎖により破壊される有機物漁礁を、廃棄物を出さず簡単に再生する方法が考慮されていない。   In the background art described in Patent Document 1, there is a technique for storing fishery products such as thinned wood in a net-like bag and trying to fix and grow fish. However, organic waste reefs destroyed by the food chain are not discharged. Easy playback method is not considered.

従って、竹材、人工林の間伐材、街路樹や植木の選定廃材、製材過程で生じる端材や廃木材などの未利用有機物を、安価な形状で貧栄養の海洋に提供する事を課題とする。   Therefore, it is an issue to provide unused organic matter such as bamboo, artificial forest thinning, roadside trees and planted waste, scrap wood and waste wood generated in the lumbering process to an oligotrophic ocean in an inexpensive form. .

前記の課題を解決するため本発明の有機物漁礁は、繊維強化プラスチックを少なくとも一部に使用した船舶が利用されている有機物漁礁であって、有機物漁礁は、水中に位置する船舶周縁部から船舶の鉛直方向上方に所定間隔を設け、外枠形成部材でもって筒状の外枠側面が形成されており、船舶周縁部或いは外枠形成部材に、或いはその両方に浮力付与手段を付加し、浮力付与手段は、内部に発泡樹脂が充填された容器からなる定常浮力部か、或いは密封された硬質容器からなる定常浮力部と、給排気ホースが接続され水面上より加圧空気の給排気で空間部の体積が変化する容器からなる変動浮力部が、単独で或いは混在して形成されており、筒状の外枠側面の下方にある船舶によって外枠下面が形成されており、外枠下面に、外枠の内部空間に充填する物体の和が嵩比重1より大きく浮力付与手段の最大浮力より小さい範囲内で、重量物が充填されており、外枠の内部空間に所定体積を持つ固体の植物性有機物が挿入されて、外枠上面が外枠形成部材でもって閉鎖されている有機物漁礁を提供する。   In order to solve the above-mentioned problems, the organic fishing reef of the present invention is an organic fishing reef in which a ship using at least a part of a fiber reinforced plastic is used. A predetermined interval is provided above the vertical direction, and the side surface of the cylindrical outer frame is formed by the outer frame forming member, and buoyancy imparting means is added to the ship periphery or the outer frame forming member, or both, to impart buoyancy. The means is a stationary buoyancy part made of a container filled with foamed resin inside, or a steady buoyancy part made of a sealed rigid container, and a space part by supplying and exhausting pressurized air from the water surface to which a supply / exhaust hose is connected. The floating buoyancy part consisting of a container whose volume changes is formed singly or mixedly, the outer frame lower surface is formed by the ship below the cylindrical outer frame side surface, Inside the outer frame A solid plant organic material having a predetermined volume is inserted into the inner space of the outer frame so that the sum of the objects to be filled is larger than the bulk specific gravity 1 and smaller than the maximum buoyancy of the buoyancy imparting means. Thus, an organic fishing reef in which the upper surface of the outer frame is closed with an outer frame forming member is provided.

前記の水中に位置する船舶周縁部とは、有機物漁礁が水中に設置されている状態を記述した表現である。   The ship peripheral part located in the said water is the expression describing the state by which the organic matter reef is installed in the water.

前記の船舶の鉛直方向上方に設ける所定間隔とは、水深や潮流により異なるが、船舶の船体長さの略4分の1から3倍程度であって、船舶を含み船舶周縁部の上方に形成される外枠の高さである。   The predetermined interval provided above the ship in the vertical direction varies depending on the water depth and tidal current, but is approximately one-fourth to three times the hull length of the ship and is formed above the periphery of the ship including the ship. Is the height of the outer frame.

船体長さの略4分の1から3倍程度の高さを持つ外枠は、大量の有機物をランダムに挿入する事が可能であり、ランダムに挿入する事によって適度の空隙が生じて稚魚や小型魚の住処が出現し、魚類の餌となる大量の水棲生物が繁殖して漁業資源が確保される。   The outer frame, which has a height of about one quarter to three times the hull length, can insert a large amount of organic matter at random. Small fish dwellings appear, and a large amount of aquatic organisms that feed on fish breed and fishery resources are secured.

前記の外枠形成部材とは、外枠の内部空間に挿入する所定体積の植物性有機物の離散を防ぎ、稚魚や小型魚が通過できる空隙を有するネット状弾性部材、ロープ部材、パイプ或いはホース状の中空部材、発泡樹脂が充填された棒状部材、船舶の内少なくとも1種以上で構成されている。   The outer frame forming member is a net-like elastic member, rope member, pipe, or hose shape that has a gap through which fry and small fish can pass, preventing dispersal of a predetermined volume of plant organic matter inserted into the inner space of the outer frame. The hollow member, the rod-shaped member filled with foamed resin, and at least one of the ships are configured.

外枠形成部材が稚魚や小型魚が通過できる空隙を有する事は、稚魚に大型魚から身を守る住処を提供する事であり、内部に挿入した有機物を分解する水棲生物を食物として提供する事であり、恒久的な漁業資源の確保に有効な手段である。   The fact that the outer frame forming member has a gap through which fry and small fish can pass is to provide a place for fry to protect themselves from large fish, and to provide aquatic organisms that decompose organic matter inserted inside as food. It is an effective means for securing permanent fishery resources.

前記の定常浮力部とは、内部に発泡樹脂が充填された容器からなる定常浮力部と、密封された硬質容器からなる定常浮力部があり、有機物漁礁を構成する筒状の外枠側面を直立させ、水中で一定姿勢を保持する為に重要である。   The steady buoyancy part includes a steady buoyancy part made of a container filled with foamed resin inside and a steady buoyancy part made of a sealed rigid container, and the cylindrical outer frame side surface constituting the organic matter reef is standing upright. This is important for maintaining a constant posture in water.

前記の変動浮力部とは、給排気ホースが接続され水面上より加圧空気の給排気で空間部の体積が変化する容器からなり、有機物漁礁を再生する為に浮上させる手段として重要である。   The fluctuating buoyancy part is composed of a container to which a supply / exhaust hose is connected and the volume of the space part is changed by supply / exhaust of pressurized air from the surface of the water, and is important as means for floating to regenerate the organic fishing reef.

前記の外枠下面に重量物が充填される事は、船舶が必然的に外枠の下方に位置し、浮力と重力を均衡させて有機物漁礁の姿勢安定を図る上で重要である。   Filling the lower surface of the outer frame with a heavy object is important in order to stabilize the posture of the organic reef by balancing the buoyancy and gravity with the ship inevitably positioned below the outer frame.

変動浮力部材に接続された前記の給排気ホースは、片方の先端が水面上に達し、水面上から変動浮力部材内に加圧空気の注入と排気を繰返す事が出来、設置場所の水圧に耐えうるホースである。   The supply / exhaust hose connected to the floating buoyancy member has one end that reaches the surface of the water, and can repeatedly inject and exhaust pressurized air into the variable buoyancy member from the surface of the water to withstand the water pressure at the installation site. It is a hose.

前記の所定体積を持つ固体の植物性有機物とは、粉末や顆粒状の物質を除く竹類や木質系有機物であって、稚魚や小型魚が通過可能な空隙を有するネット状弾性部材から容易に離脱しない体積を持つ植物性有機物である。   The solid plant organic matter having the predetermined volume is bamboo or woody organic matter excluding powder and granular substances, and can be easily obtained from a net-like elastic member having a gap through which fry and small fish can pass. It is a plant organic substance with a volume that does not leave.

また有機物漁礁が安定した形状を保つ為に、前記筒状の外枠側面に付加する外枠周回部材があって、外枠周回部材は、水平方向に外枠を周回する定型或いは略定型をしており、密閉された硬質の中空部材、或いは発泡樹脂が充填されたパイプ状部材、ホース状部材、棒状部材、或いはロープ状部材、の少なくとも一種以上で構成されており、外枠周回部材が外枠側面に付加されている、或いは外枠側面の最上部を構成している有機物漁礁を提供する。   In addition, in order to maintain a stable shape of the organic reef, there is an outer frame revolving member added to the side surface of the cylindrical outer frame, and the outer frame revolving member has a fixed shape or a substantially fixed shape that revolves around the outer frame in the horizontal direction. It is composed of at least one of a sealed hard hollow member, or a pipe-like member filled with foamed resin, a hose-like member, a rod-like member, or a rope-like member, and the outer frame surrounding member is Provided is an organic fishing reef that is added to the side of the frame or that constitutes the uppermost part of the side of the outer frame.

定型或いは略定型をした前記の外枠周回部材が、筒状の外枠側面に付加され、或いは外枠側面の最上部を構成している事は、筒状の外枠側面を直立させ、水中で一定姿勢を保持する為に必要である。   The outer frame orbiting member having a fixed or substantially fixed shape is added to the side surface of the cylindrical outer frame or constitutes the uppermost part of the side surface of the outer frame. This is necessary to maintain a constant posture.

また有機物漁礁を安定した姿勢で浮上させる為に、前記筒状の外枠側面に付加する姿勢制御装置であって、姿勢制御を担う姿勢制御ロープ部材が、前記の船舶周縁部に左右略均等に複数個接続されており、各姿勢制御ロープ部材は、筒状の外枠側面を経由して外枠側面の最上部の前記外枠周回部材を周回して外枠側面の外側に出され、外枠側面の外側で、移動式重量物が移動可能な状態で付加されて先端が船舶船底に接続され、浮上時の姿勢制御装置として付与された有機物漁礁を提供する。   In addition, in order to float the organic fishing reef in a stable posture, the posture control device is attached to the side surface of the cylindrical outer frame, and the posture control rope member responsible for the posture control is arranged substantially evenly on the left and right sides of the ship periphery. A plurality of the attitude control rope members are routed around the outer frame revolving member at the top of the outer frame side surface through the cylindrical outer frame side surface and are taken out to the outside of the outer frame side surface. Provided is an organic reef provided as a posture control device at the time of ascent when a mobile heavy object is added in a movable state on the outside of the side surface of the frame and the tip is connected to the ship bottom.

前記の姿勢制御を担う姿勢制御ロープ部材とは、有機物漁礁の再生作業を行う時、筒状の外枠側面の略中心部に船舶を浮上させる為の姿勢制御を担うロープであって、左右略均等に配置する必要があるので複数個とした。
従って前記の複数個とは、2の倍数であって通常は2×1、2×2、2×3、2×4、2×5である。
The attitude control rope member responsible for the attitude control is a rope responsible for attitude control for levitating the ship to the approximate center of the side surface of the cylindrical outer frame when regenerating the organic matter reef. Since it is necessary to arrange evenly, it was set as plural.
Therefore, the plurality is a multiple of 2 and is usually 2 × 1, 2 × 2, 2 × 3, 2 × 4, 2 × 5.

前記の移動式重量物とは、姿勢制御ロープ部材を通す空洞部があり、空洞部の直径はロープ直径の略2〜10倍あり、当該漁礁に使用する合計重量が、外枠最上部の浮力付与手段の浮力範囲内にあって各個数に均等配分されており、空洞部に姿勢制御ロープ部材を通す事によって、ロープ内の最下点に移動可能な重量物である。   The mobile heavy object has a cavity through which the posture control rope member is passed, and the diameter of the cavity is approximately 2 to 10 times the diameter of the rope, and the total weight used for the fishing reef is the buoyancy at the top of the outer frame. It is a heavy object that is within the buoyancy range of the applying means and is equally distributed to each number, and that can be moved to the lowest point in the rope by passing the attitude control rope member through the cavity.

前記の姿勢制御装置が付加された有機物漁礁が浮上する時、水面上よりの加圧空気の注入で最上部の変動浮力部材の空間体積が増加して浮上が開始され、最初に外枠最上段が水面まで浮上し、続いて上部の浮力部材から順に浮上する事になる。   When the organic reef with the above attitude control device ascends, the space volume of the uppermost variable buoyancy member is increased by injecting pressurized air from the surface of the water, and the ascending is started. Ascend to the surface of the water, and then surface from the top buoyancy member.

浮上に伴って筒状の外枠側面は収縮し、収縮に伴って緩んだ姿勢制御ロープ部材は外枠の外側にある移動可能な重量物によって引っ張られ、重量物は順次最下点に移動する。
前記の姿勢制御ロープ部材が左右略均等に配置されている事により、移動式重量物が同重量である事により、外枠最上部が外側に浮上し、上部から順に内側に浮上し、最後に船舶が略中心部に浮上する。
The side surface of the cylindrical outer frame contracts as it floats, and the posture control rope member loosened as it contracts is pulled by a movable heavy object outside the outer frame, and the heavy object moves sequentially to the lowest point. .
Since the posture control rope members are arranged substantially equally on the left and right, the movable heavy object has the same weight, so that the uppermost part of the outer frame floats outward, then floats inward from the top, and finally The ship rises to the approximate center.

また有機物漁礁が折りたたまれて浮上する機能を強化する為に、前記筒状の外枠側面に前記外枠周回部材が所定段数設けられており、各所定段の外枠周回部材は、前記定常浮力部が単独で外枠周回部材を構成しているか、或いは給排気口を有し密閉された略同体積の弾性部材からなる前記変動浮力部の複数個を略均等配分して付加された外枠周回部材とが、単独で或いは混在して形成されており、各所定段の変動浮力部は、給排気ホースで連結されており、各所定段間の変動浮力部も給排気ホースで連結されており、最上段の変動浮力部の給排気口は、片方が水面上に達した給排気ホースに接続されており、最下段の変動浮力部に排気専用口が取付けられている有機物漁礁を提供する。   In addition, in order to enhance the function of the organic reef being folded and levitated, a predetermined number of the outer frame revolving members are provided on the side surface of the cylindrical outer frame, and the outer frame revolving members of each predetermined step have the steady buoyancy. An outer frame in which a plurality of the floating buoyancy portions are made of substantially the same volume of elastic members that are sealed and have an air supply / exhaust port. Circulating members are formed singly or mixedly, the floating buoyancy parts of each predetermined stage are connected by a supply / exhaust hose, and the variable buoyancy parts between the predetermined stages are also connected by a supply / exhaust hose. In addition, the air supply / exhaust port of the uppermost floating buoyancy part is connected to the air supply / exhaust hose, one of which reaches the surface of the water, and the lowermost floating buoyancy part is provided with an organic exhaust reef. .

前記の所定段数とは、2〜10段程度であって、筒状の外枠側面が水中にあって安定した形状を保持する役目を強化し、浮上する時の姿勢制御に役立つ。   The predetermined number of steps is about 2 to 10 steps, and the side surface of the cylindrical outer frame is in water and strengthens the role of maintaining a stable shape, which is useful for posture control when ascending.

各所定段に均等配分された変動浮力部は、最上段から最下段の変動浮力部が1単位の給排気ホースで連結され、水面上に達した給排気ホースから給気する事によって変動浮力部の上方から体積が増加して浮力が生じ、最下段まで移行した気圧が水圧に勝った場合は最下段の排気専用口から排出され、変動浮力部内の気圧は水圧と均衡する。   Fluctuating buoyancy parts evenly distributed to each predetermined stage are connected to each other by a unit of air supply / exhaust hose and supplied from the air supply / exhaust hose reaching the water surface. When the volume increases from above and buoyancy occurs, and the atmospheric pressure that has shifted to the lowest level exceeds the water pressure, the pressure is discharged from the exhaust port at the lowest level, and the atmospheric pressure in the variable buoyancy part is balanced with the water pressure.

また有機物漁礁が折りたたまれて浮上する機能を強化する為に、前記筒状の外枠側面に前記外枠周回部材が所定段数設けられており、各所定段の外枠周回部材は、前記定常浮力部が単独で外枠周回部材を構成しているか、或いは給排気口を有し閉鎖された硬質或いは準硬質の定型容器からなる前記変動浮力部の複数個を略均等配分して付加された外枠周回部材とが、単独で或いは混在して形成されており、各所定段の変動浮力部は、給排気ホース或いはパイプ状部材或いは伸曲するホース状部材で連結されており、各所定段間の変動浮力部は、給排気ホース或いは伸曲するホース状部材で連結されており、最上段の変動浮力部の給排気口は、片方が水面上に達した給排気ホースに接続されており、最下段の変動浮力部は、少なくとも下部の一部が開放されている有機物漁礁を提供する。   In addition, in order to enhance the function of the organic reef being folded and levitated, a predetermined number of the outer frame revolving members are provided on the side surface of the cylindrical outer frame, and the outer frame revolving members of each predetermined step have the steady buoyancy. The outer part is configured as an outer frame rotating member by itself, or the outer part is provided with a plurality of the variable buoyancy parts made of a rigid or semi-rigid fixed container having an air supply / exhaust opening and distributed substantially evenly. The frame orbiting members are formed singly or mixedly, and the variable buoyancy portions of each predetermined stage are connected by a supply / exhaust hose, a pipe-shaped member, or an extending hose-shaped member, The variable buoyancy part is connected with a supply / exhaust hose or a hose-like member that extends, and the supply / exhaust port of the uppermost variable buoyancy part is connected to the supply / exhaust hose with one side reaching the water surface, The bottom floating buoyancy part is at least one But to provide the organic matter reefs that are open.

前記の閉鎖された硬質或いは準硬質の定型容器とは、1.1気圧以下では変形しない閉鎖可能な定型容器であって、水中にある定型容器は常時水圧の影響下にあり、同時に加圧空気を注入する事によって過剰な内圧が生じる場合がある。
この弊害を避けるため、本発明では連結された最下段の定型容器の下部を開放する事により、下方から水が浸入し或いは排出される為、定型容器内は常時水圧と均衡している。
The closed rigid or semi-rigid fixed container is a closable fixed container that does not deform below 1.1 atm. The fixed container in the water is always under the influence of water pressure and at the same time pressurized air. Excessive internal pressure may be generated by injecting.
In order to avoid this problem, in the present invention, by opening the lower part of the connected lowermost fixed container, water enters or is discharged from below, so that the fixed container is always in balance with the water pressure.

前記の有機物漁礁を水面下の安定した位置に設置する為に、前記筒状の外枠側面の最上部は、水面にあって独立しており、内部に発泡樹脂が充填された容器からなる定常浮力部材と、或いは密封された硬質容器からなる定常浮力部材と、牽引手段でもって連結されている有機物漁礁を提供する。   In order to install the organic matter reef at a stable position below the surface of the water, the uppermost part of the side surface of the cylindrical outer frame is on the surface of the water and is independent, and is a steady state consisting of a container filled with foamed resin inside. An organic reef is provided which is connected to a buoyancy member, or a steady buoyancy member made of a sealed rigid container, and a traction means.

吊漁礁として安定した位置に有機物漁礁を設置する為に、有機物漁礁の水中重力が浮力より若干重くなる程度に設定し、その重力と浮力の差よりも大きな浮力を有し水面上にある独立した定常浮力部に接続する方法が最良である。   In order to install the organic reef in a stable position as a suspended reef, the underwater gravity of the organic reef is set to be slightly heavier than the buoyancy, and it has a buoyancy greater than the difference between its gravity and buoyancy and is independent on the water surface The method of connecting to the steady buoyancy part is the best.

前記の有機物漁礁を有効に利用する為に、前記の水面にあって独立している定常浮力部材の複数個が、棒状或いはパイプ状或いは板状の部材でもって水面で接続されて一体化して集合浮力部材として形成されており、集合浮力部材に複数個の前記有機物漁礁が接続されている有機物漁礁を提供する。   In order to effectively use the organic matter reef, a plurality of independent buoyancy members that are independent of each other on the water surface are connected and integrated by a rod-like, pipe-like, or plate-like member. Provided is an organic matter reef that is formed as a buoyancy member and in which a plurality of the organic matter reefs are connected to a collective buoyancy member.

前記の水面とは、常時波の影響下にある為に水面下略30cmから水面上略60cmを含む概念であって、複数個とは設置海域や用途によって著しく異なるが2個から略120個である。   The above-mentioned water surface is a concept including approximately 30 cm below the water surface and approximately 60 cm above the water surface because it is always under the influence of waves. is there.

有機物漁礁は一定海域に固定する必要があり、前記の筒状の外枠側面は、或いは前記の外枠下面は、或いは前記の水面にあって独立している定常浮力部材は、或いは前記の集合浮力部材は、海底に設置された装置と係留手段によって係留されており、係留手段は離脱と接続を繰返す事ができる有機物漁礁を提供する。   It is necessary to fix organic reefs in a certain sea area, and the side surface of the cylindrical outer frame, the lower surface of the outer frame, or the stationary buoyancy member that is on the water surface and independent, or the assembly The buoyancy member is moored by a device installed on the seabed and mooring means, and the mooring means provides an organic reef that can be repeatedly detached and connected.

また有機物漁礁は、漁礁をより安定させるために隣接する漁礁同士を外枠連結手段でもって接続し、横移動を制限し、水中で安定した漁礁群を提供する。   In addition, organic fishing reefs connect adjacent reefs with outer frame connecting means to further stabilize the reefs, limit lateral movement, and provide a stable reef group in water.

前記の有機物漁礁が、水面から吊下げられて、或いは海底或いは湖底に設置されて、定置網の一部として使用されている、或いは定置網と合体している、或いは集魚施設の一部として使用されている、或いは集魚施設と合体している有機物漁礁集合体を提供する。   The organic reefs are suspended from the surface of the water, installed on the seabed or lake bottom, used as part of a stationary net, combined with a stationary net, or used as part of a fish collection facility Provide organic reef aggregates that are or are integrated with fish collection facilities.

前記の有機物漁礁は、稚魚や小型魚が自由に通過できる外枠を持っている事から安全な住処が確保され、有機物を食する水棲生物が食料となって稚魚や小型魚が繁殖する。
従って、その小型魚を求めて大型魚が集まり、大型魚を捕獲する効率の良い定置網や集魚施設の補助手段となった、或いは定置網や集魚施設の一部となった有機物漁礁集合体を提供する。
Since the organic reef has an outer frame through which fry fish and small fish can pass freely, a safe residence is secured, and aquatic organisms that eat organic matter are used as food to breed fry and small fish.
Therefore, in order to find the small fish, large fish gather and provide an organic reef aggregate that has become an efficient means of catching large fish and an auxiliary means of a stationary net and a fish collection facility, or has become a part of a stationary net and a fish collection facility .

前記課題を解決する方法として、本発明では繊維強化プラスチック船舶の中古船或いは廃船をも利用し、未利用資源を活用し、安価な有機物漁礁を目指した。
FRP船は、14万隻と推定される放置艇に加え毎年1万隻を越える隻数が廃船時期を迎えているが、軽量で高強度、高耐久性である優れた製品特性が解体時になって災いし、安価で有効なリサイクル技術、新たなエネルギーを消費しないリユースが課題とされている。
As a method for solving the above-mentioned problems, the present invention aims at an inexpensive organic fishing reef by utilizing a used ship or abandoned ship of a fiber reinforced plastic ship, utilizing unused resources.
The number of FRP ships, which are estimated to be 140,000 in addition to the neglected boats, is reaching abandonment every year. However, the excellent product characteristics of light weight, high strength, and high durability are at the time of dismantling. Recycling that is cheap and effective and that does not consume new energy is an issue.

図1〜4は同一の実施例であるが、まず図1に基づき記述する。
繊維強化プラスチック船舶の中古漁船(10)からデッキや付属部品を取除いた船体(長さ13m×巾2.5m×深さ1m)を利用し、その周縁部から上方に筒状の外枠側面を製作する。

以上述べてきた如く、本発明は廃棄物を利用し、新たなエネルギーの投入を最小限にとどめ、漁業資源の復活を提起する。
森が海を育てる、この重要課題が再認識され、植林を行う漁業者が現れ始めているが、人工林は3倍の幼木を植林し、間伐を繰返す事によって立派な針葉樹林に成長するものの、山村の過疎化と高齢化によって放置され、超過密に陥った人工林は生物の本能に従って最後の力を振り絞り、数倍もの花粉をばら撒いている。
間伐をして豊かな森林に育て上げる事は、花粉症対策の医療費削減にも寄与する。
As described above, the present invention uses waste, minimizes the input of new energy, and proposes the restoration of fishery resources.
Forests nurture the sea, this important issue has been reaffirmed, and fishermen who are planting trees are beginning to appear, but planted forests grow into splendid coniferous forests by planting three times as many young trees and repeating thinning. Abandoned due to the depopulation and aging of the mountain village, the overgrown plantation has squeezed its last power according to the instincts of the organism and scattered pollen several times.
Thinning and growing into rich forests also contributes to reducing medical expenses for hay fever countermeasures.

街路樹や植木の選定廃材は、水分を含んだまま化石燃料を浪費して焼却処分されており、その有効利用が切望されている。   Waste trees selected from roadside trees and planted trees are incinerated by wasting fossil fuels while containing moisture, and their effective use is desired.

また、竹の進出によって森林が破壊されている地域がある。
昔の竹林被害は、地下茎を延ばして隣地に進出する程度であったが、現在の竹林被害は道路等の境界域に忽然と現れた数本の竹が、1〜2ヶ月で成長して樹木の上空を覆い、地下茎を縦横に張り巡らせ、瞬く間に森林を破壊しながら竹林へと姿を変え、野生動物でさえ立ち入ることが出来ない荒廃した竹林に変貌している。
照葉樹林は、地中深くに根を下ろし、緑のダムとして雨水を蓄え、多様な生物を育む豊かな森林を形成するのに反し、竹林は表層にのみ根を張って貧栄養な単一の生物層を形成し、枯れた竹はぽっかりと地中に穴を開け、大規模な地滑りの要因をはらんでいる。
森林に進出した貧栄養の竹を伐採する事は、植林して森を育てるよりも簡単で効果的な方法であり、豊かな森林の復元が切望さている。
これらの現象は、九州・四国を含む本州の南部地方で顕著に見られる現象で、現在はまだ里山近くの出来事であるものの、数年先には山奥にまで達する勢いで拡大し、進行しており、近い将来、日本中の森林が再生不可能となる事態が充分予測され、早急な対策が差し迫っている。
There are also areas where forests are being destroyed by the advance of bamboo.
The old bamboo forest damage was to extend to the adjacent land by extending the rhizome, but the current bamboo forest damage is a few trees that suddenly appeared on the border areas such as roads grew in a month or two Covering the sky, stretching the underground stems vertically and horizontally, quickly transforming into a bamboo forest while destroying the forest, transforming into a ruined bamboo forest that even wild animals cannot enter.
The laurel forest is deeply rooted in the ground, stores rainwater as a green dam, and forms a rich forest that nurtures diverse organisms. Forming a biological layer, the withered bamboo gaps deeply into the ground, causing large-scale landslides.
Cutting oligotrophic bamboo that has entered the forest is a simpler and more effective method than planting and growing the forest, and the restoration of a rich forest is eagerly desired.
These phenomena are prominently seen in the southern region of Honshu, including Kyushu and Shikoku, and are still happening near Satoyama, but in a few years ahead, they spread to the depths of the mountains and progressed. In the near future, it is fully predicted that forests in Japan will become unrenewable, and immediate measures are imminent.

一方海では、コンブ・ワカメ・カジメ・ホンダワラなど、かっては多くの海藻が繁茂していた日本の沿岸海域は、背後に展開する豊かな森林によって支えられていた。
森林が失われ、開発によって土砂が流入し、垂直護岸によって浄化機能に満ちた浅瀬や干潟が失われ、有機物の供給がダム湖によって分断され、海底ではサンゴモによる石灰層の拡大で磯焼けが蔓延し、海藻が消失して魚群が姿を消し、里海は壊滅的打撃を受けている。
亜熱帯地方の海域でも、多種類の生物が息づくサンゴ礁のすぐ隣で、オニヒトデの異常繁殖により、或いは赤土の流入により、或いは海水温の上昇によって死滅したサンゴ礁が拡大し、海の砂漠が広がっている。
海藻やサンゴ礁の減少は、海藻にしか産卵しない魚類、海藻によって育まれる魚類が枯渇するのは当然であり、途切れた食物連鎖を復活させねばならない。
On the other hand, in the sea, Japan's coastal waters, where many seaweeds such as kombu, wakame, kajime, and hondawala were once prosperous, were supported by the rich forests behind them.
Forests are lost, earth and sand flows in through development, shallow waters and tidal flats filled with purification functions are lost due to vertical revetment, the supply of organic matter is divided by the dam lake, and the limestone layer is expanded by coral spiders on the sea floor, and the burning of the toast is widespread However, seaweed disappeared and the school of fish disappeared, and Satoumi was devastated.
Even in subtropical waters, coral reefs that are killed by coral reefs that live with a variety of organisms, by abnormal breeding of giant starfish, by inflow of red soil, or by rising seawater temperature, are expanding and the sea desert is spreading. .
The decrease in seaweed and coral reefs naturally depletes fish that lay eggs only on seaweed and fish grown by seaweed, and it is necessary to restore a broken food chain.

大都市近郊の限られた海域は、水に溶けた窒素やリンの大量の養分が供給され、微生物が爆発的に増殖して赤潮などの弊害が生まれているが、その反面で多くの沿岸海域が有機物やミネラルの供給不足にあえいでいる。
森林が育んだ貴重な有機物資源を海洋に運ぶ河川には、多くのダムが横たわって水が澱み、有機物が堰き止められ、低酸素状態の湖底で無気分解され、里海が貧栄養に曝されている。
里海は豊かな森林と繋がって初めて生きるのであり、ダム湖で遮断された河川に替わり、本発明が固体の有機物を海洋に提供する事によって食物連鎖を完成させる。
The limited sea area near large cities is supplied with a large amount of nutrients such as nitrogen and phosphorus dissolved in water, causing microorganisms to explode and causing adverse effects such as red tide, but on the other hand, many coastal sea areas However, there is a shortage of organic and mineral supplies.
Rivers that carry precious organic resources grown in forests to the ocean, many dams lay down, water is stagnated, organic matter is dammed up, and airlessly decomposed at the bottom of hypoxic lakes, and satoumi is exposed to poor nutrition. ing.
Satoumi lives only when it is connected to abundant forests. Instead of rivers cut off by dam lakes, the present invention completes the food chain by providing solid organic matter to the ocean.

しかし、里海に恒久的な漁業資源が復活する事は大きな経済効果であっても、高額の漁礁では費用に対する経済効果が伴わず、実効性が無い。
本発明は、持続的な食物連鎖の原点である固体の有機物を大量に供給し、有機物が分解され消失した時に漁礁を再生する手段に主眼を置き、繊維強化プラスチック船舶の中古や廃船を利用する事によって安価な有機物漁礁を可能にし、安価な有機物漁礁が連結した大規模漁礁群によって恒久的な漁業資源が確保され、或いは既存の定置網漁と合体させて里海が復活し、外洋に進出しなくとも生計が成り立つ事は漁村の活性化に繋がる。
里山においても、廃竹材や木質有機物の未利用資源が活用される事は、新たな雇用と活気が蘇り、漁村と山村を結びつけた大きな経済効果が期待できる。
However, even if the permanent recovery of fishery resources in Satoumi is a major economic effect, it is not effective for high-priced fishing reefs because there is no economic effect on costs.
The present invention supplies a large amount of solid organic matter, which is the origin of a sustainable food chain, and focuses on means for regenerating a fishing reef when the organic matter is decomposed and lost, and uses second-hand or abandoned fiber-reinforced plastic ships. By doing so, it is possible to make cheap organic fishing reefs, and permanent fishing resources are secured by large-scale reefs connected by cheap organic fishing reefs, or satoumi is revived by combining with existing stationary net fishing and advance into the open ocean Even if it is possible to make a living, the fishing village will be activated.
In Satoyama, the utilization of unused resources such as waste bamboo and woody organic materials will bring back new employment and vitality, and can be expected to have a great economic effect connecting fishing villages and mountain villages.
