Description
本発明は漁礁形成具並びに漁礁形成方法に関する。詳しくは、例えば海底に沈下させて漁礁を形成するための、漁礁形成具並びに漁礁形成方法に係るものである。 The present invention relates to a fishing reef forming tool and a fishing reef forming method. Specifically, the present invention relates to a fishing reef forming tool and a fishing reef forming method for forming a reef by sinking to the seabed, for example.
沿岸海域は、内陸部における広葉樹林の減少と人工林の荒廃の影響を大きく受け、さらには、埋立て、工業排水および生活排水によって汚染されているので、漁業資源が壊滅的打撃を受けている。 Coastal waters are heavily affected by the decline of broad-leaved forests and man-made forests in inland areas, and are also devastated by fishery resources because they are contaminated by landfills, industrial effluents and domestic effluents. .
このような漁業資源の打撃に対処するため、コンクリートブロックの人工漁礁を海中に設置して、魚類の生育場所と隠れ場を形成することが行なわれている。しかし、このような人工漁礁は、海中に栄養分を供給する機能を有していない。 In order to cope with such a blow of fishery resources, an artificial reef of concrete block is installed in the sea to form a habitat and a hiding place for fish. However, such artificial reefs do not have a function of supplying nutrients into the sea.
そこで、例えば特許文献１には、図５に示されるようなハイブリッド漁礁１１０が記載されている。すなわち、ハイブリッド漁礁１１０は、孔部１１１Ａが貫通して形成されたコンクリート製の底盤１１１と、底盤１１１上の孔部１１１Ａの角部近傍に立設された鋼製の柱材１１２と、柱材１１２の上端部を連結する横桁材１１３と、鋼材（１１４、１１５、１１６）によって形成された各棚部上に横置状として並置固定された間伐材１１８とを備えている。
Thus, for example, Patent Literature 1 describes a
しかしながら、特許文献１に記載されたハイブリッド漁礁は、コンクリート製の底盤を備えているので、設置場所がある程度平らな場所に限定されてしまい、しかも、間伐材の交換時にハイブリッド漁礁を吊り上げて回収する為の大掛かりな装置が必要であった。 However, since the hybrid fishing reef described in Patent Document 1 has a concrete bottom plate, the installation location is limited to a flat place to some extent, and the hybrid fishing reef is lifted and collected when the thinning material is replaced. A large-scale device was necessary.
本発明は、以上の点に鑑みて創案されたものであり、どこでも簡単に設置することができる漁礁形成具、並びにこのような漁礁形成具を用いた漁礁形成方法を提供することを目的とする。 The present invention has been developed in view of the above points, and an object thereof is to provide a fishing reef forming tool that can be easily installed anywhere, and a reef forming method using such a fishing reef forming tool. .
上記の目的を達成するために、本発明の漁礁形成具は、浮体と、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成された植物集合体と、前記植物の水分通導管に対して略平行方向に且つ前記植物に囲まれた空間に通されると共に、一端が前記浮体に取付けられ、さらに前記水分通導管の方向において前記植物集合体の長さよりも長い線状部材と、該線状部材の他端に取付けられた錘とを備える。 In order to achieve the above object, a fishing reef formation tool of the present invention is a plant assembly formed by binding a floating body and a plurality of plants arranged so that moisture conduits are positioned substantially parallel to each other. And passing through a space surrounded by the plant in a direction substantially parallel to the moisture conduit of the plant, and having one end attached to the floating body, and further in the direction of the moisture conduit of the plant assembly. A linear member longer than the length, and a weight attached to the other end of the linear member.
また、上記の目的を達成するために、本発明の漁礁形成具は、浮体と、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成された植物集合体と、前記植物の水分通導管に対して略平行方向に前記植物集合体に取付けられると共に、両端に開口部が形成され、前記植物の水分通導管に対して略平行に位置する水分通導管を有する植物円筒体と、該植物円筒体の内部に通されると共に、一端が前記浮体に取付けられ、前記植物円筒体の断面積よりも小さい断面積を有し、さらに前記水分通導管の方向において前記植物集合体の長さよりも長い線状部材と、該線状部材の他端に取付けられた錘とを備える。 In order to achieve the above object, the fishing reef formation tool of the present invention is a plant in which a floating body and a plurality of plants arranged so that moisture conduits are positioned substantially parallel to each other are bound by a bound body. The assembly is attached to the plant assembly in a direction substantially parallel to the water conduit of the plant, and an opening is formed at both ends, and the moisture passage located substantially parallel to the moisture conduit of the plant. A plant cylinder having a conduit, passed through the plant cylinder, one end attached to the floating body, having a cross-sectional area smaller than the cross-sectional area of the plant cylinder, and A linear member longer than the length of the plant aggregate in the direction, and a weight attached to the other end of the linear member.
ここで、植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通されると共に、一端が浮体に取付けられ、さらに水分通導管の方向において植物集合体の長さよりも長い線状部材と、線状部材の他端に取付けられた錘とによって、錘が水中に沈み、錘に引っ張られる形で植物に囲まれた空間に通された線状部材が鉛直方向に延びるようになる。 Here, it is passed through the space surrounded by the plant in a direction substantially parallel to the moisture conduit of the plant, and one end is attached to the floating body, and is longer than the length of the plant aggregate in the direction of the moisture conduit. The linear member and the weight attached to the other end of the linear member cause the weight to sink in the water, and the linear member passed through the space surrounded by the plant so as to be pulled by the weight extends in the vertical direction. become.
その結果、植物集合体の水分通導管は水面に対して略垂直になり、言い換えれば水中で植物が立った状態になり、よって植物に加わる上下の水圧差と植物の中の空気の浮力によって、植物の水分通導管に下から水が浸入し、空気が上方から追い出され、植物が水より重くなって、植物集合体は沈む。 As a result, the moisture conduit of the plant assembly is substantially perpendicular to the water surface, in other words, the plant is standing in the water, and thus, due to the difference between the upper and lower water pressure applied to the plant and the buoyancy of the air in the plant, Water enters the moisture conduit of the plant from below, air is expelled from above, the plant becomes heavier than water, and the plant aggregate sinks.
また、植物円筒体が、植物の水分通導管に対して略平行方向に植物集合体に取付けられる場合、植物円筒体が植物に囲まれた空間に通される場合よりも、束ねられた植物集合体に後から植物円筒体を取付けることができるので、漁礁形成具を製作しやすい。 In addition, when the plant cylinder is attached to the plant assembly in a direction substantially parallel to the water conduit of the plant, the bundled plant assembly is more than the case where the plant cylinder is passed through the space surrounded by the plants. Since the plant cylindrical body can be attached to the body later, it is easy to produce a fishing reef forming tool.
また、本発明の漁礁形成具は、植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通されると共に、両端に開口部が形成され、植物の水分通導管に対して略平行に位置する水分通導管を有し、さらに線状部材の断面積よりも大きい断面積を有する植物円筒体を備え、線状部材は、植物円筒体の内部に通されたこととすることができる。 The fishing reef former of the present invention is passed through the space surrounded by the plant in a direction substantially parallel to the moisture conduit of the plant, and has openings at both ends. A plant cylindrical body having a cross-sectional area larger than the cross-sectional area of the linear member, and the linear member is passed through the interior of the plant cylindrical body. be able to.
この場合、線状部材の断面積よりも植物円筒体の断面積の方が大きく、しかも円筒形であるので、線状部材が植物円筒体の内部において引っ掛かりにくくなる。 In this case, since the cross-sectional area of the plant cylindrical body is larger than the cross-sectional area of the linear member and is cylindrical, the linear member is less likely to be caught inside the plant cylindrical body.
また、本発明の漁礁形成具は、線状部材のうち、浮体と植物集合体との間の領域および植物集合体と錘との間の領域にそれぞれ固定されると共に、水分導通管に対して略垂直方向において、植物に囲まれた空間の長さよりも長いプレート部材を備えることとすることもできる。 Further, the reef forming tool of the present invention is fixed to the region between the floating body and the plant assembly and the region between the plant assembly and the weight of the linear member, and to the moisture conducting tube. In a substantially vertical direction, a plate member longer than the length of the space surrounded by the plant can be provided.
この場合、植物集合体が沈み始めると、浮体と植物集合体との間の領域に固定されたプレート部材との距離が拡がり、また、植物集合体と錘との間の領域に固定されたプレート部材との距離が縮まるので、植物集合体が沈み始めたかどうかを確認しやすくなる。 In this case, when the plant assembly begins to sink, the distance between the floating member and the plate member fixed in the region between the plant assembly increases, and the plate fixed in the region between the plant assembly and the weight. Since the distance to the member is reduced, it is easy to check whether the plant aggregate has started to sink.
また、この場合、水分導通管に対して略垂直方向において、植物に囲まれた空間の長さよりも長いので、プレート部材と浮体との間の線状部材を切断し、浮体から切り離して植物集合体を海底に沈める場合には、プレート部材が植物集合体に引っ掛かり、線状部材が植物集合体から抜け難くなる。 Further, in this case, the length of the space surrounded by the plant is longer in a direction substantially perpendicular to the moisture conducting tube, so that the linear member between the plate member and the floating body is cut, separated from the floating body, and the plant assembly When the body is submerged in the seabed, the plate member is caught on the plant aggregate, and the linear member is difficult to come off from the plant aggregate.
また、本発明の漁礁形成具において、植物円筒体の半径方向における錘の長さは、植物円筒体の直径よりも短いこととすることができる。 In the fishing reef formation tool of the present invention, the length of the weight in the radial direction of the plant cylinder can be shorter than the diameter of the plant cylinder.
この場合、植物集合体の植物中の空気が抜けて植物集合体が沈んでも、錘は植物円筒体の内部を通るので、植物集合体と共に沈むことはなく、その後の錘の回収の手間を省くことができる。 In this case, even if the air in the plants of the plant aggregate escapes and the plant aggregate sinks, the weight passes through the inside of the plant cylindrical body, so it does not sink with the plant aggregate and saves the trouble of collecting the weight thereafter. be able to.
また、本発明の漁礁形成具において、浮体から離れた植物の端部は、浮体に近い植物の端部よりも植物の根に近い箇所であることとすることができる。 Moreover, in the fishing reef forming tool of the present invention, the end of the plant away from the floating body can be a location closer to the root of the plant than the end of the plant close to the floating body.
この場合、植物は、根から茎を通って枝先へ水が流れるように構成されており、さらに、浮体から離れた植物の端部は、浮体に近い植物の端部よりも海中深くに位置して大きな水圧を受けるので、水が植物中を通りやすくなり、それによって植物中の空気も抜けやすくなる。 In this case, the plant is configured such that water flows from the root through the stem to the branch tip, and the end of the plant away from the floating body is located deeper in the sea than the end of the plant close to the floating body. Since the water pressure is high, the water easily passes through the plant, and the air in the plant also easily escapes.
また、本発明の漁礁形成具において、結束体および線状部材は、それぞれ鉄製であることとすることができる。
この場合、鉄から鉄イオンが放出され、鉄を栄養分とする微生物を繁殖させることができ、よって、微生物を餌とする魚を引きつけることができる。
Moreover, in the fishing reef formation tool of this invention, a united body and a linear member can each be made from iron.
In this case, iron ions are released from iron, and microorganisms that use iron as nutrients can be propagated, and therefore fish that feed on microorganisms can be attracted.
また、本発明の漁礁形成具において、結束体および線状部材は、それぞれ植物繊維で構成されたこととすることができる。
この場合、微生物を繁殖させやすく、よって、魚が好んで寄ってくる。また、この場合、鉄製の結束体や鉄製の線状部材に比べて分解が速い。
In the fishing reef forming tool of the present invention, the bundle and the linear member can be made of plant fibers, respectively.
In this case, it is easy for the microorganisms to propagate, and therefore fish prefers. Moreover, in this case, the decomposition is quicker than the iron bundle and the iron linear member.
また、本発明の漁礁形成具において、植物の両端は、植物の水分通導管に対して略垂直方向に切断加工されたこととすることができる。 In the fishing reef forming tool of the present invention, both ends of the plant can be cut in a substantially vertical direction with respect to the moisture conduit of the plant.
この場合、植物の両端が開放口になり、この開放口が空気の出口になるので、植物中の空気が抜けやすくなる。 In this case, both ends of the plant become open ports, and this open port becomes an air outlet, so that the air in the plant can easily escape.
また、本発明の漁礁形成具において、植物は、複数の切れ目を有することとすることができる。 Moreover, in the fishing reef formation tool of the present invention, the plant can have a plurality of cuts.
この場合、切れ目によって、植物の水分通導管を切断することになり、チップ状にする効果と同等の効果が得られる。
また、切れ目によって、植物を断片状にすることができると共に、水分通導管を縦方向に制御できる。
また、切れ目によって、植物の浮力消滅までの時間を著しく短縮できる。
In this case, the cut water cuts the water conduit of the plant, and an effect equivalent to the effect of making it into a chip shape is obtained.
Moreover, a plant can be made into a fragment form with a cut | interruption, and a moisture conduit can be controlled to the vertical direction.
Moreover, the time until the buoyancy of the plant disappears can be remarkably shortened by the cut.
また、上記の目的を達成するために、本発明の漁礁形成方法は、浮体と、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成された植物集合体と、前記植物の水分通導管に対して略平行方向に且つ前記植物に囲まれた空間に通されると共に、一端が前記浮体に取付けられ、さらに前記水分通導管の方向において前記植物集合体の長さよりも長い線状部材と、該線状部材の他端に取付けられた錘とを備える漁礁形成具を水に浮かせる工程と、水に浮かんだ前記漁礁形成具の前記植物集合体が、浮かび始めの前記植物集合体の位置から沈んだか確認する工程と、前記植物集合体が沈んだことを確認した場合に、前記植物集合体を前記浮体から分離して水底へ沈める工程とを備える。 In order to achieve the above object, the method for forming a reef according to the present invention is a plant in which a floating body and a plurality of plants arranged so that moisture conduits are positioned substantially parallel to each other are bound together by a bound body. The assembly is passed in a space substantially parallel to the moisture conduit of the plant and surrounded by the plant, one end is attached to the floating body, and the plant assembly is further attached in the direction of the moisture conduit. A step of floating a fishing reef former having a linear member longer than the length of the body and a weight attached to the other end of the linear member in the water, and the plant assembly of the fishing reef former floating in the water A step of confirming whether or not the plant aggregate has settled from the position of the beginning of floating, and a step of separating the plant aggregate from the floating body and sinking it to the bottom of the water when confirming that the plant aggregate has subsided .
また、上記の目的を達成するために、本発明の漁礁形成方法は、浮体と、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成された植物集合体と、前記植物の水分通導管に対して略平行方向に前記植物集合体に取付けられると共に、両端に開口部が形成され、前記植物の水分通導管に対して略平行に位置する水分通導管を有し、さらに前記線状部材の断面積よりも大きい断面積を有する植物円筒体と、該植物円筒体の内部に通されると共に、一端が前記浮体に取付けられ、さらに前記水分通導管の方向において前記植物集合体の長さよりも長い線状部材と、該線状部材の他端に取付けられた錘とを備える漁礁形成具を水に浮かせる工程と、水に浮かんだ前記漁礁形成具の前記植物集合体が、浮かび始めの前記植物集合体の位置から沈んだか確認する工程と、前記植物集合体が沈んだことを確認した場合に、前記植物集合体を前記浮体から分離して水底へ沈める工程とを備える。 In order to achieve the above object, the method for forming a reef according to the present invention is a plant in which a floating body and a plurality of plants arranged so that moisture conduits are positioned substantially parallel to each other are bound together by a bound body. The assembly is attached to the plant assembly in a direction substantially parallel to the water conduit of the plant, and an opening is formed at both ends, and the moisture passage located substantially parallel to the moisture conduit of the plant. A plant cylinder having a conduit and a cross-sectional area larger than the cross-sectional area of the linear member; the plant cylinder is passed through the plant cylinder; one end is attached to the floating body; and the moisture conduit A step of floating a fishing reef former having a linear member longer than the length of the plant assembly in the direction of the wire, and a weight attached to the other end of the linear member, and the fishing reef former floating in the water Of the plant aggregates began to float Wherein comprising a step of confirming whether sank from the position of the plant assembly, when it is confirmed that the sunken said plant assemblies, and a step of submerging the plant assembly to the bottom of the water is separated from said floating body.

Moreover, the fish reef former 1 of the present invention includes a timber aggregate (an example of a plant aggregate) 3. Here, in the

また、本発明の漁礁形成具１は、材木３Ａの水分通導管に対して略平行方向に且つ材木３Ａに囲まれた空間に通されると共に、両端に開口部が形成され、材木３Ａの水分通導管に対して略平行に位置する水分通導管を有する竹筒（植物円筒体の一例である。）７を備える。

また、本発明の漁礁形成具１は、竹筒７の内部に通されると共に、一端が浮体２に取付けられ、竹筒７の断面積よりも小さい断面積を有し、さらに水分通導管の方向において材木集合体３の長さ（例えば約２ｍ）よりも長い（例えば約３〜３．５ｍ）針金（線状部材の一例である。）５を備える。
In addition, the fish reef former 1 of the present invention is passed through the inside of the
また、本発明の漁礁形成具１は、針金５の他端に取付けられた錘６を備える。錘６の質量は、例えば５０〜１００ｋｇである。
また、竹筒７の半径方向における錘６の長さは、竹筒７の直径よりも長いが、竹筒７の直径よりも短いこととしてもよい。

また、プレート部材８は鉄製である。
Further, the reef forming tool 1 of the present invention is fixed to a region of the
The
ここで、線状部材が、植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通されるのであれば、線状部材は、必ずしも植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通された植物円筒体に通されなくてもよい。 Here, if the linear member is passed through the space surrounded by the plant in a direction substantially parallel to the moisture conduit of the plant, the linear member is not necessarily substantially relative to the moisture conduit of the plant. It does not have to be passed through the plant cylinder passed through the space surrounded by the plants in the parallel direction.
しかし、線状部材を、植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通す場合よりも、植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通された植物円筒体に通す方が、線状部材と植物集合体が互いに引っ掛かりにくくなり、円滑に植物集合体が線状部材に沿って沈むことができるので好ましい。 However, the linear member is surrounded by the plant in a direction substantially parallel to the moisture passage of the plant and in a direction substantially parallel to the moisture passage of the plant and through the space surrounded by the plant. Passing through the plant cylindrical body passed through the space is preferable because the linear member and the plant aggregate are less likely to catch each other, and the plant aggregate can sink smoothly along the linear member.
また、浮体２は必ずしも１つでなくてもよく、本発明の漁礁形成具１は、複数の浮体を備えることもできる。
Moreover, the floating
また、植物集合体が、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成されていれば、植物には、枝葉が付いていてもよい。 Further, if the plant aggregate is configured by binding a plurality of plants arranged so that the moisture conduits are positioned substantially parallel to each other, the plant may have branches and leaves.
また、植物集合体を結束できるのであれば、結束体は必ずしも、わら縄でなくてもよく、例えば、結束体として針金を用いてもよいし、また、わら縄と針金を併用してもよい。 Moreover, as long as a plant assembly can be bound, the bound body does not necessarily have to be a straw rope. For example, a wire may be used as the bound body, or a straw rope and a wire may be used in combination. .
また、線状部材が、植物の水分通導管に対して略平行方向に且つ植物に囲まれた空間に通され、一端が浮体に取付けられ、さらに水分通導管の方向において植物集合体の長さよりも長いのであれば、必ずしも針金でなくてもよく、例えば、麻紐などの天然繊維製の紐であってもよい。 Further, the linear member is passed through the space surrounded by the plant in a direction substantially parallel to the moisture conduit of the plant, one end is attached to the floating body, and further, the length of the plant aggregate in the direction of the moisture conduit. If it is long, it does not necessarily have to be a wire. For example, it may be a natural fiber string such as a hemp string.
また、植物円筒体として、竹筒を用いているが、必ずしも竹筒でなくてもよく、杉などの材木の内部を空洞にして得られた円筒体を用いてもよい。 Moreover, although bamboo cylinders are used as plant cylinders, they are not necessarily bamboo cylinders, and cylinders obtained by making the interior of timber such as cedar hollow may be used.
また、植物集合体が、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成されていれば、必ずしも浮体から離れた植物の端部は、浮体に近い植物の端部よりも植物の根に近い箇所でなくてもよい。 In addition, if the plant assembly is configured by binding a plurality of plants arranged so that the moisture conduits are located substantially parallel to each other, the end of the plant apart from the floating body is not necessarily the floating body. It does not have to be closer to the root of the plant than the end of the nearby plant.
しかし、浮体から離れた植物の端部は、浮体に近い植物の端部よりも植物の根に近い箇所であれば、植物は、根から茎（幹）を通って枝先へ水が流れるように構成されており、さらに、浮体から離れた植物の端部は、浮体に近い植物の端部よりも海中深くに位置して大きな水圧を受けるので、水が植物中を通りやすくなり、それによって植物中の空気も抜けやすくなって好ましい。 However, if the end of the plant away from the floating body is closer to the root of the plant than the end of the plant close to the floating body, the plant flows from the root through the stem (stem) to the branch tip. Furthermore, the end of the plant away from the floating body is located deeper in the sea than the end of the plant close to the floating body and receives a large water pressure, so that water can easily pass through the plant, thereby It is preferable because air in the plant is easily removed.
また、植物集合体が、互いに水分通導管が略平行に位置するよう並べられた複数の植物が結束体で結束されて構成されていれば、必ずしも植物の両端は、植物の水分通導管に対して略垂直方向に切断加工されていなくてもよい。 In addition, if the plant aggregate is configured by binding a plurality of plants arranged so that the moisture conduits are positioned substantially parallel to each other, the ends of the plant are not necessarily connected to the moisture conduit of the plant. Therefore, it may not be cut in a substantially vertical direction.
しかし、植物の両端が、植物の水分通導管に対して略垂直方向に切断加工されていれば、植物の両端が開放口になり、この開放口が空気の出口になるので、植物中の空気が抜けやすくなり、好ましい。 However, if both ends of the plant are cut and processed in a direction substantially perpendicular to the moisture conduit of the plant, both ends of the plant become open ports, and the open ports serve as air outlets. Is preferable because it is easy to come off.
また、必ずしも材木に切れ目が形成されていなくてもよい。
しかし、材木に切れ目が形成されていれば、水分通導管（例えば、道管や仮道管）を切断して、材木をチップ状にする効果と同等の効果が得られるので好ましい。
Moreover, the cut | interruption does not necessarily need to be formed in the timber.
However, it is preferable that a cut is formed in the timber because an effect equivalent to the effect of cutting the moisture conduit (for example, a road pipe or a temporary road pipe) to make the timber into a chip shape can be obtained.
また、材木に切れ目が形成されていれば、材木を断片状にすることができると共に、水分通導管（例えば、道管や仮道管）を全て縦方向に制御できるので好ましい。
また、材木に切れ目が形成されていれば、材木の浮力消滅までの時間を著しく短縮できるので好ましい。
In addition, it is preferable that the timber has a cut line, because the timber can be made into pieces and the moisture conduits (for example, the trachea and the temporary trachea) can be controlled in the vertical direction.
In addition, it is preferable that the timber has a cut line because the time until the buoyancy disappears can be significantly shortened.

また、本発明の漁礁形成具の第二の実施態様において、プレート部材８は、針金５のうち、浮体２と竹筒３との間の領域および竹筒７と錘６との間の領域にそれぞれ固定されると共に、竹筒の水分導通管に対して略垂直方向において、竹筒７の直径よりも長い。
その他の点は図１に示された本発明の漁礁形成具の第一の実施態様と同じである。
Further, in the second embodiment of the fishing reef forming tool of the present invention, the
Other points are the same as those of the first embodiment of the fishing reef former of the present invention shown in FIG.
図４は、本発明の漁礁形成具を海底に設置する様子を説明するための概略図である。図４を用いて本発明の漁礁形成具を用いた漁礁形成方法を説明する。 FIG. 4 is a schematic view for explaining a state where the fishing reef former of the present invention is installed on the seabed. The fishing reef formation method using the fishing reef formation tool of this invention is demonstrated using FIG.
海水９に投入された本発明の漁礁形成具１は、図４（ａ）に示されるように、浮体２によって海水９において浮く。また、一端に浮体２が取付けられた針金５の他端には、錘６が取付けられているので、錘６が水中に沈み、錘６に引っ張られる形で材木集合体３に通された針金５が鉛直方向に延びる。
The fishing reef formation tool 1 of the present invention thrown into the seawater 9 floats in the seawater 9 by the floating
また、図４（ａ）に示されるように、海水９に投入されて間もないときは、材木集合体３の材木中に空気が多く存在しているので、材木３Ａは海水９よりも軽く、従って材木集合体３は、浮体２近くのプレート部材８に接する位置にある。
Further, as shown in FIG. 4A, when the
次に、浮かび始めから３〜２１日程度経過した後、浮かび始めの位置から材木集合体３が沈んだかを確認する。
Next, after about 3 to 21 days have passed since the beginning of the floating, it is confirmed whether the
そして、材木集合体３の材木中の空気が抜けて、図４（ｂ）に示されるように、材木集合体３が錘６近くのプレートへ沈んだことが確認された場合に、図４（ｃ）に示されるように、針金５を切断して、錘６、針金５およびプレート部材８と共に、材木集合体３を浮体２から分離し、海底１０に沈める。
Then, when it is confirmed that the air in the timber of the
図４を用いて、材木集合体３と共に錘６、針金５およびプレート部材８も沈めた例を説明したが、材木集合体３を浮体２から分離することができれば、針金５を切断する必要はない。
The example in which the
例えば、錘６近くのプレート部材８を省略すると共に、竹筒７の半径方向における錘６の長さを竹筒７の直径よりも短くすれば、材木集合体３の材木中の空気が抜けて材木集合体３が沈んでも、錘６は竹筒７の内部を通るので、材木集合体３だけを浮体２から分離することができる。
For example, if the
また、本発明の漁礁形成具１を複数個連結し、漁礁の形成予定場所まで、漁船が複数の漁礁形成具１を曳航すると、曳航中に、単に漁礁形成具１を浮かばせた場合よりも早く材木集合体３の材木中の空気が抜け、漁船が漁礁の形成予定場所に到着したときに、すぐに材木集合体３を浮体２から分離して海底１０に沈めることができる。
空気の抜けが早くなる理由としては、曳航中の水流などが影響しているからだと考えられる。
In addition, when a plurality of reef formers 1 of the present invention are connected and a fishing boat tow a plurality of reef formers 1 to a place where the reefs are to be formed, than when the reef former 1 is simply floated during towing. As soon as the air in the timber of the
It is thought that the reason why the air escape becomes faster is that the current during towing has an effect.
以上のように、本発明の漁礁形成具は、材木の水分通導管に対して略平行方向に且つ材木に囲まれた空間に通される（すなわち、材木に囲まれた空間に通された竹筒に通される）と共に、一端が浮体に取付けられ、さらに水分通導管の方向において材木集合体の長さよりも長い針金と、針金の他端に取付けられた錘とを備えるので、錘が水中に沈み、錘に引っ張られる形で材木に囲まれた空間に通された針金が鉛直方向に延びるようになる。 As described above, the fishing reef forming tool of the present invention is passed through the space surrounded by the timber in a direction substantially parallel to the timber moisture conduit (that is, the bamboo cylinder passed through the space surrounded by the timber). One end is attached to the floating body, and further includes a wire longer than the length of the timber aggregate in the direction of the moisture conduit, and a weight attached to the other end of the wire. The wire passed through the space surrounded by the timber while sinking and being pulled by the weight extends in the vertical direction.
その結果、材木集合体の水分通導管は水面に対して略垂直になり、言い換えれば水中で材木が立った状態になり、よって材木に加わる上下の水圧差（例えば直径１０ｃｍ、長さ３ｍの材木の場合、２３ｋｇ）と材木の中の空気の浮力によって、材木の水分通導管に下から水が浸入し、空気が上方から追い出され、材木が水より重くなって、材木集合体は沈む。 As a result, the moisture conduit of the timber aggregate is substantially perpendicular to the water surface, in other words, the timber is standing in the water, so that the difference between the upper and lower water pressure applied to the timber (for example, a timber having a diameter of 10 cm and a length of 3 m) In this case, the buoyancy of the air in the timber and 23 kg) causes water to enter the moisture conduit of the timber from below, the air is expelled from above, the timber becomes heavier than the water, and the timber aggregate sinks.
よって、漁礁を形成したい場所付近に、本発明の漁礁形成具を浮かばせておくだけで、材木集合体が沈み始め、材木集合体を浮体から分離させて海底に沈めるだけで、どのような形状の海底でも簡単に漁礁を設置できる。 Therefore, just by floating the reef former of the present invention near the place where you want to form a fishing reef, the timber aggregate starts to sink, and the timber aggregate is separated from the floating body and submerged on the seabed, so Fishing reefs can be easily installed on the sea floor.
特に、竹筒の半径方向における錘の長さを、竹筒の直径よりも短くすれば、材木集合体の材木中の空気が抜けて材木集合体が沈んでも、錘は竹筒の内部を通るので、材木集合体だけを浮体から分離して海底に沈めることができ、本発明の漁礁形成具を浮かばせておくだけで漁礁を設置できる。
また、錘が材木集合体と共に沈むことはなく、その後の錘の回収の手間を省くことができる。
In particular, if the length of the weight in the radial direction of the bamboo cylinder is made shorter than the diameter of the bamboo cylinder, the weight will pass through the inside of the bamboo cylinder even if the timber aggregate sinks due to the release of air in the timber aggregate. Only the aggregate can be separated from the floating body and submerged on the seabed, and the fishing reef can be installed only by floating the fishing reef former of the present invention.
Further, the weight does not sink together with the timber aggregate, and it is possible to save the trouble of collecting the weight thereafter.
また、材木を結束する「わら縄」は、植物繊維で構成されており、微生物を繁殖させやすく、よって、魚が好んで寄ってくる。 In addition, the “straw rope” that binds timbers is made of plant fibers and is easy to propagate microorganisms.
また、針金も材木集合体と一緒に海底に沈められ、漁礁の一部となるが、針金の鉄から鉄イオンが放出され、鉄を栄養分とする微生物を繁殖させることができ、よって、微生物を餌とする魚を引きつけることができる。 Also, the wire is submerged together with the timber aggregate and becomes part of the reef, but iron ions are released from the iron of the wire, and it is possible to propagate microorganisms that use iron as nutrients, thus Attract fish to feed.
また、プレート部材は、針金のうち、浮体と材木集合体との間の領域および材木集合体と錘との間の領域にそれぞれ固定されているので、材木集合体が沈み始めると、浮体と材木集合体との間の領域に固定されたプレート部材との距離が拡がり、材木集合体と錘との間の領域に固定されたプレート部材との距離が縮まる。よって、材木集合体が沈み始めたかどうかを確認しやすい。 Further, since the plate member is fixed to a region of the wire between the floating body and the timber aggregate and an area between the timber aggregate and the weight, when the timber aggregate starts to sink, the floating body and the timber The distance between the plate member fixed in the region between the aggregates increases and the distance between the plate member fixed in the region between the timber aggregates and the weight decreases. Therefore, it is easy to confirm whether the timber aggregate has started to sink.
また、プレート部材は、水分導通管に対して略垂直方向において、竹筒の直径よりも長いので、プレート部材が竹筒に引っ掛かり、針金が竹筒さらには材木集合体から抜け難い。 Further, since the plate member is longer than the diameter of the bamboo cylinder in a direction substantially perpendicular to the moisture conducting tube, the plate member is caught by the bamboo cylinder, and the wire is difficult to come off from the bamboo cylinder and the timber aggregate.
また、浮体から離れた材木の端部は、浮体に近い材木の端部よりも材木の根に近い箇所であるから、材木は、根から幹を通って枝先へ水が流れるように構成されており、さらに、浮体から離れた材木の端部は、浮体に近い材木の端部よりも海中深くに位置して大きな水圧を受けるので、水が材木中を通りやすくなり、それによって材木中の空気も抜けやすい。 Also, because the end of the timber away from the floating body is closer to the root of the timber than the end of the timber close to the floating body, the timber is configured so that water flows from the root through the trunk to the branch tip. In addition, the end of the timber away from the floating body is located deeper in the sea than the end of the timber close to the floating body and receives a large water pressure, so that water can easily pass through the timber and thereby the air It is easy to come off.
さらに、材木の両端部は、水分通導管に対して略垂直方向に切断加工されているので、材木の両端が開放口になり、この開放口が空気の出口になるので、材木中の空気が抜けやすい。 Further, since both ends of the timber are cut in a direction substantially perpendicular to the moisture conduit, both ends of the timber become open ports, and the open ports serve as air outlets. Easy to come off.
また、材木には、切れ目が形成されているので、水分通導管（例えば、道管や仮道管）が切断されて、材木をチップ状にする効果と同等の効果が得られる。
また、材木に切れ目が形成されているので、材木を断片状にすることができると共に、水分通導管（例えば、道管や仮道管）を全て縦方向に制御できる。
また、材木に切れ目が形成されているので、材木の浮力消滅までの時間を著しく短縮できる。
Moreover, since the cut is formed in the timber, an effect equivalent to the effect of cutting the moisture conduit (for example, a road pipe or a temporary road pipe) and making the timber into chips is obtained.
In addition, since the cuts are formed in the timber, the timber can be fragmented, and all the moisture conduits (for example, the road pipe and the temporary road pipe) can be controlled in the vertical direction.
In addition, since the cuts are formed in the timber, the time until the buoyancy disappears of the timber can be remarkably shortened.
