Description

本発明は、網場のフロートに浮島の機能を兼ね備えさせた網場に関するものである。   The present invention relates to a mesh field in which the float of the mesh field also has a floating island function.

ダム、湖沼、河川等において流木、塵芥をせき止めて回収するとともに、景観を損なうことなく、水質の浄化、水面の緑化を行うために、従来から網場が使用されている。 この網場をダム、湖沼、河川等に設置することにより、野鳥の保護のための休息地又は魚類、昆虫類の水中生物繁殖のための産卵場所を提供することができ、その結果、自然環境保護を図ることができる。   Traditionally, nets have been used to dampen and collect driftwood and dust in dams, lakes, rivers, etc., and to purify water quality and green the water without sacrificing the landscape. By installing this network in dams, lakes, rivers, etc., it is possible to provide a resting place for the protection of wild birds or a spawning place for the propagation of aquatic organisms of fish and insects. Protection can be achieved.

従来、植生浮島は流木、塵芥に埋まることを避け、また、景観造成の観点から、人目に触れる所に設置して来たのに対して、流木、塵芥をせき止めて回収する網場は、流木、塵芥が景観を損なうので、人目に触れにくい上流その他の場所に設置して来た。そして、このような網場として、例えば、特許文献１のような技術が提案されている。   Traditionally, vegetation floating islands have been installed in places where people can see them from the viewpoint of landscape creation, while avoiding being buried in driftwood and dust. Because the rubbish detracts from the scenery, it has been installed upstream and other places where it is difficult to touch. And as such a network, the technique like patent document 1 is proposed, for example.

特開平１０−１１０４２４号公報（第２〜３頁、図３、図５）Japanese Patent Laid-Open No. 10-110424 (pages 2 and 3, FIGS. 3 and 5)

従来、植生浮島、網場をそれぞれ別個に設置して来たため、その設置場所に制約があるだけでなく、設置費用が嵩むことが問題となっていた。また、限られた施設で大きい効果を得ることが求められている。
一方、網場は風で飛来する塵芥を止める機能を果たすことが必要であるが、そのためには主ロープを通常水面上０．５ｍ位の高さに配置する必要がある。
また、上記特許文献１には、植生浮島に網場のロープを配置する一例が開示されているが、この技術によれば、主ロープの高さを水面上０．５ｍ位の高さに配置するためには、植生浮島の寸法を大きくする必要がある。 Conventionally, vegetation floating islands and nets have been installed separately, so that not only the installation location is restricted, but also the installation cost is problematic. In addition, it is required to obtain a large effect in a limited facility.
On the other hand, the net is required to fulfill the function of stopping the dust flying by the wind. For this purpose, it is necessary to arrange the main rope usually at a height of about 0.5 m above the water surface.
Moreover, although the example which arrange | positions the rope of a netting field to a vegetation floating island is disclosed by the said patent document 1, according to this technique, the height of a main rope is arrange | positioned at the height of about 0.5 m on a water surface. To do so, it is necessary to increase the size of the vegetation floating island.

本発明者等は、網場のフロートに浮島の機能を兼ね備えさせることにより、上述した欠点を解決できることを見出した。   The inventors of the present invention have found that the above-mentioned drawbacks can be solved by combining the float of the Aiba with the function of floating islands.

すなわち、本発明では、水生植物その他の植物を植栽し得るようにしたフロートを有するものとした。このようにすると、網場と浮島とを一体に構成することができ、係留設備を共用することにより、設置費用並びに維持経費を大幅に削減することができる。特に、水位の変動が大きく、水深の深いダムでは、設置費用における係留設備の割合が大きいため、より効果的である。また、網場のフロートに浮島の機能を兼ね備えさせることができ、このフロートに水生植物その他の植物を植栽することができるのみならず、植生浮島の周囲をフロートがカバーしているので、植生浮島が塵芥中に埋没するおそれがない。さらに、堆積した流木、塵芥を植物が繁茂した植生浮島によって視界から遮ることができるので、景観が向上する。   That is, the present invention has a float that can plant aquatic plants and other plants. If it does in this way, a network and a floating island can be comprised integrally, and installation cost and a maintenance cost can be reduced significantly by sharing mooring equipment. In particular, dams with large water level fluctuations and deep water depths are more effective because of the large proportion of mooring equipment in the installation costs. In addition, the float of Aiba can have the function of floating islands, and not only can you plant aquatic plants and other plants on this float, but also the vegetation floating islands are covered by the float, There is no risk of floating islands being buried in the garbage. In addition, the accumulated driftwood and dust can be shielded from view by the vegetation floating islands where plants have grown, so the landscape is improved.

内部が発泡材からなり、その外面を合成樹脂で被覆したフロートからなるものとすることが望ましい。この場合には、フロートをできるだけ軽くすることができるのみならず、流木でフロートが損傷するのを防止できる。   It is desirable that the inside is made of a foam and the outside surface is made of a float coated with a synthetic resin. In this case, not only can the float be made as light as possible, but also the float can be prevented from being damaged by driftwood.

網場の主ロープと網を前後から抱き合わせ得るように、フロートを縦２分割構造としておくとよい。フロートを縦２分割構造としておくと、網場と浮島の組立・分解が容易になる。   The float may be divided into two vertically-divided structures so that the main rope and net of the net can be tied together from the front and back. If the float has a vertically divided structure, it is easy to assemble and disassemble the net and floating islands.

フロートに、植生基盤材を収容し得る凹部を設けておくことが望ましい。この場合には、フロートの凹部に植生基盤材をすっぽりと収容することができるので、植生基盤材を安定して保持できるのみならず、植生基盤材の周囲がフロートで保護されて破損しにくい。   It is desirable to provide the float with a recess that can accommodate the vegetation base material. In this case, since the vegetation base material can be completely accommodated in the concave portion of the float, not only can the vegetation base material be stably held, but the periphery of the vegetation base material is protected by the float and is not easily damaged.

請求項１記載の発明によれば、以下に述べるような効果がある。
(1) 網場と浮島とを一体に構成することができ、係留設備を共用することにより、設置費用並びに維持経費を大幅に削減することができる。特に、水位の変動が大きく、水深の深いダムでは、設置費用における係留設備の割合が大きいため、より効果的である。
(2) 網場のフロートに浮島の機能を兼ね備えさせることができ、このフロートに水生植物その他の植物を植栽することができるのみならず、植生浮島の周囲をフロートがカバーしているので、植生浮島が塵芥中に埋没するおそれがない。

Hard to break.

本発明の好ましい実施の形態を、図面に基づいて詳細に説明する。図１に、本発明による浮島式網場の設置状態の一例を示す。そのうち、図１(a)は正面図、図１(b)はその側面図である。この浮島式網場は、網場のフロートに浮島の機能を兼ね備えさせたところに特徴がある。   Preferred embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, an example of the installation state of the floating island type net place by this invention is shown. 1A is a front view and FIG. 1B is a side view thereof. This floating island type Aiba is characterized by the fact that the float of Aiba has the functions of a floating island.

ダム、湖沼、河川等設置場所の両岸に張り渡した上下２本のロープ１ａ，１ｂ間に網２ａを張り、また、下側のロープ１ｂから網２ｂを垂下させる。そして、上側のロープ１ａと上側の網２ａの上端とを結束ロープ３ａで、また、上側の網２ａの下端と下側のロープ２ｂと下側の網２ｂの上端とを結束ロープ３ｂで結束する。なお、下側の網２ｂの下端部には、沈錘４（本例では、チェン）が取り付けられている。   A net 2a is stretched between the two upper and lower ropes 1a, 1b stretched on both banks of the dam, lake, river, etc., and the net 2b is suspended from the lower rope 1b. The upper rope 1a and the upper end of the upper net 2a are bound by a binding rope 3a, and the lower end of the upper net 2a, the lower rope 2b, and the upper end of the lower net 2b are bound by a binding rope 3b. . A sink weight 4 (in this example, a chain) is attached to the lower end of the lower net 2b.

上側のロープ１ａは水面Ｗ.Ｌより上に支持し、このロープ１ａと下側のロープ２ｂとを利用して上下２枚の網２ａ，２ｂからなる網体２にフロート５を取り付ける。フロート５の内部を発泡ウレタンその他の発泡材とすることができ、その外面をウレタン樹脂その他の合成樹脂で被覆しておくとよい。このようにすると、フロート５をできるだけ軽くすることができるのみならず、流木でフロート５が損傷するのを防止できる。フロート５はＦＲＰで作製してもよい。   The upper rope 1a is supported above the water surface W.L, and the float 5 is attached to the net body 2 composed of two upper and lower nets 2a and 2b using the rope 1a and the lower rope 2b. The interior of the float 5 can be made of foamed urethane or other foamed material, and its outer surface is preferably covered with a urethane resin or other synthetic resin. In this way, not only can the float 5 be made as light as possible, but also the float 5 can be prevented from being damaged by driftwood. The float 5 may be made of FRP.

また、上側のロープ１ａと下側のロープ２ｂとを利用して網体２にフロート５を取り付けるに当って、ここでは、網場のロープ１ａ，１ｂと網体２とを前後から抱き合わせ得るように、フロート５を縦２分割構造としてある。すなわち、図３の左側と右側とに示すように、左右対称形である縦２分割構造のフロート５ａ，５ｂの接合面に、上側のロープ１ａと下側のロープ２ｂを縦２分割した場合の半分を嵌め込むことのできる大きさの溝６ａ，６ｂ、７ａ，７ｂがフロート５ａ，５ｂの幅方向に形成してある。   In addition, when the float 5 is attached to the net body 2 using the upper rope 1a and the lower rope 2b, the net ropes 1a and 1b and the net body 2 can be entangled from the front and rear. The float 5 has a vertically divided structure. That is, as shown on the left side and the right side of FIG. 3, the upper rope 1a and the lower rope 2b are vertically divided into two on the joint surface of the floats 5a and 5b having a vertically divided structure that is bilaterally symmetric. Grooves 6a, 6b, 7a, 7b having a size capable of fitting half are formed in the width direction of the floats 5a, 5b.

したがって、これら縦２分割構造のフロート５ａ，５ｂを１枚の網体２の表側と裏側から抱き合わせると、１枚の網体２を挟んで表側と裏側から縦２分割構造のフロート５ａ，５ｂを一体的ならしめることができる。このとき、図１(b)に示すように、上下２本のロープ１ａ，１ｂは上下の溝６ａ，６ｂ、７ａ，７ｂ内に納まる。縦２分割構造のフロート５ａ，５ｂを一体的ならしめるに当っては、例えば、フロート５ａ，５ｂを表側から裏側に貫通するボルトとこれに螺合させ得るナットからなる固定具（図２(b)において、符号５ｃで略記する）を挙げることができるが、この固定具のみに限定されるものではなく、ロープその他の緊締具を用いて縦２分割構造のフロート５ａ，５ｂを一体的ならしめてもよい。   Accordingly, when the floats 5a and 5b having the vertically divided structure 2 are joined together from the front side and the back side of the single mesh body 2, the floats 5a and 5b having the vertically split structure from the front side and the back side with the single mesh body 2 interposed therebetween. Can be integrated. At this time, as shown in FIG. 1B, the two upper and lower ropes 1a and 1b are accommodated in the upper and lower grooves 6a, 6b, 7a and 7b. When the floats 5a and 5b having a vertically divided structure are integrally formed, for example, a fixing tool including a bolt that penetrates the floats 5a and 5b from the front side to the back side and a nut that can be screwed to the bolt (FIG. 2B). ) Is abbreviated as 5c), but is not limited to this fixing tool, and the floats 5a and 5b having a vertically divided structure are integrated with a rope or other fastening tool. Also good.

フロート５ａ，５ｂを縦２分割構造としておくと、網場と浮島の組立・分解が容易になる。そして、縦２分割構造のフロート５ａ，５ｂは、いずれも、水生植物その他の植物を植栽し得るようになっている。例えば、図２に示すように、フロート５に平面Ｕ字状の枠体８を形成し、その裏面（下面）にフロート５ａ，５ｂの幅方向の端から端に達する受桟８ａと、この受桟８ａと一体的であって平面Ｕ字状の枠体８の手前側に達する左右２本の受桟８ｂ，８ｂを取り付ければ、その枠内の凹部８ｃに植生基盤材９を収容することができる。また、図４に示すように、平面Ｕ字状の枠体８の枠内を有底とし、それに複数個の凹窩８ｄ，８ｄを形成すれば、凹部８ｃの各凹窩８ｄ，８ｄに水生植物の苗を植え込むことができる。したがって、図２に示す場合においても図４に示す場合においても、フロート５ａ，５ｂに水生植物その他の植物を植栽することができる。なお、例えば、平面Ｕ字状の枠体８の裏面（下面）から貫通して上面に達するように取り付けられるボルト８ｅとナット８ｆとにより、受桟８ａ，８ｂを枠体８の裏面（下面）に取り付けることができる。   If the floats 5a and 5b have a vertically divided structure, the assembling and disassembling of the net and the floating island becomes easy. Each of the floats 5a and 5b having a vertically divided structure can plant aquatic plants and other plants. For example, as shown in FIG. 2, a flat U-shaped frame 8 is formed on the float 5, and a receiving bar 8a reaching the end of the floats 5a and 5b in the width direction on the back surface (lower surface) thereof, and this receiving bar 8a If the two left and right receiving bars 8b, 8b that are integral with the flat U-shaped frame 8 are attached, the vegetation base material 9 can be accommodated in the recess 8c in the frame. Further, as shown in FIG. 4, if the inside of the plane U-shaped frame body 8 has a bottom and a plurality of recesses 8d and 8d are formed on the bottom, aquatic can be applied to each recess 8d and 8d of the recess 8c. Plant seedlings can be planted. Therefore, in both the case shown in FIG. 2 and the case shown in FIG. 4, aquatic plants and other plants can be planted on the floats 5a and 5b. For example, the receiving bars 8a and 8b are attached to the rear surface (lower surface) of the frame body 8 by bolts 8e and nuts 8f that are attached so as to penetrate the rear surface (lower surface) of the plane U-shaped frame body 8 and reach the upper surface. Can be attached.

植生基盤材９は、例えば、図５(a)、(b)に示すように、フロート５ａ，５ｂの枠内の凹部８ｃに収容させ得る大きさを有する網目板９ａ上の中央に、マット状の植物繊維（例えば、ヤシ殻繊維）を載置するとともに、その周囲を立体網状マット９ｃで囲み、それらの上面と四周を１枚のネット９ｄで覆ったものである。
網目板９ａは例えば硬質樹脂成型品とすることができる。また、立体網状マット９ｃは例えばポリエチレン製とすることができる。このような植生基盤材９にも、水生植物の苗を植え込むことができる。なお、植生基盤材９の全体の高さは、１０〜１５ｃｍ程度である。 For example, as shown in FIGS. 5 (a) and 5 (b), the vegetation base material 9 has a mat shape at the center on the mesh plate 9a having a size that can be accommodated in the recess 8c in the frame of the floats 5a and 5b. Plant fiber (for example, coconut shell fiber) is placed, the periphery thereof is surrounded by a three-dimensional net-like mat 9c, and the upper surface and four circumferences thereof are covered by a single net 9d.
The mesh plate 9a can be, for example, a hard resin molded product. The three-dimensional mesh mat 9c can be made of, for example, polyethylene. An aquatic plant seedling can also be planted in such a vegetation base material 9. In addition, the whole height of the vegetation base material 9 is about 10-15 cm.

フロート５の平面Ｕ字状の枠体８内の凹部８ｃに、この植生基盤材９をすっぽりと収容することができる。したがって、植生基盤材９を安定して保持できるのみならず、植生基盤材９の周囲がフロート５で保護されて破損しにくい。なお、図２(a)においては、枠体８内の凹部８ｃに収容されている植生基盤材９を、斜線で略記してある。   The vegetation base material 9 can be completely accommodated in the concave portion 8 c in the plane U-shaped frame 8 of the float 5. Therefore, not only can the vegetation base material 9 be stably held, but the periphery of the vegetation base material 9 is protected by the float 5 and is not easily damaged. In FIG. 2 (a), the vegetation base material 9 accommodated in the recess 8c in the frame 8 is abbreviated by hatching.

かくして、上下２枚の網２ａ，２ｂからなる網体２により網場を構成することができる。また、この１枚の網体２を挟んで表側と裏側から縦２分割構造のフロート５ａ，５ｂを抱き合わせ、両フロート５ａ，５ｂに備えられている枠体８内の凹部８ｃに植生基盤材９を収容し、この植生基盤材９に水生植物の苗を植え込めば、あるいは、平面Ｕ字状の枠体８の枠内の底部分に形成されている複数個の凹窩８ｂ，８ｂに水生植物の苗を植え込めば、浮島を構成することができる。   Thus, a network field can be constituted by the network body 2 composed of the upper and lower two networks 2a and 2b. In addition, the floats 5a and 5b having a vertically divided structure are joined to each other from the front side and the back side with the single net 2 interposed therebetween, and the vegetation base material 9 is placed in the recess 8c in the frame 8 provided in both the floats 5a and 5b. If a seedling of an aquatic plant is planted in the vegetation base material 9, or aquatic is formed in the plurality of recesses 8 b, 8 b formed in the bottom portion of the plane U-shaped frame 8. Floating islands can be constructed by planting plant seedlings.

このように、網場のフロートに浮島の機能を兼ね備えさせることにより、網場と浮島とを一体に構成することができる。そして、網場と浮島の係留設備を共用すれば、設置費用並びに維持経費を大幅に削減することができる。特に、水位の変動が大きく、水深の深いダムでは、設置費用における係留設備の割合が大きいため、より効果的である。また、網場のフロートに浮島の機能を兼ね備えさせることができ、このフロートに水生植物その他の植物を植栽することができるのみならず、植生浮島の周囲をフロートがカバーしているので、植生浮島が塵芥中に埋没するおそれがない。さらに、堆積した流木、塵芥を植物が繁茂した植生浮島によって視界から遮ることができるので、景観が向上する。   In this way, the network can be integrated with the floating island by combining the float of the network with the function of a floating island. And if you share the mooring facilities between Aiba and Ukishima, you can significantly reduce the installation and maintenance costs. In particular, dams with large water level fluctuations and deep water depths are more effective because of the large proportion of mooring equipment in the installation costs. In addition, the float of Aiba can have the function of floating islands, and not only can you plant aquatic plants and other plants on this float, but also the vegetation floating islands are covered by the float, There is no risk of floating islands being buried in the garbage. In addition, the accumulated driftwood and dust can be shielded from view by the vegetation floating islands where plants have grown, so the landscape is improved.

ここでは、ダム、湖沼、河川等に直接設置して流木、塵芥をせき止めるのに適用した場合を例示したが、ダム、堰その他の水門設備、取水設備やその付帯設備の流木止め、塵芥止めに適用することもできる。   Here, the case where it is directly installed in a dam, lake, river, etc. and applied to clog driftwood and dust is shown as an example, but for driftwood and dust control of dams, weirs and other sluice facilities, intake facilities and their associated facilities It can also be applied.
