Description
【０００１】[0001]
本考案は、魚道のない既存の堰等に簡単に設けることのできる簡易魚道装置に 関するものである。 The present invention relates to a simple fishway device that can be easily installed in an existing weir without a fishway.
【０００２】[0002]
従来、河川に設けられたダム、堰は、貯水、水害防止等に利用されている。近 年、設計され構築されたダム、堰においては、魚の生態系を維持するために魚道 を併設したものがある。魚道には、ダム、堰を迂回するコンクリート製の上流側 から下流側までの傾斜した長い水路を設け、該水路にコンクリート製または鋼板 製の隔壁を複数個間隔を開けて設けたものがある。この魚道の水位は隔壁により 階段状に形成される。通常、上流の水位の変動に合わせて隔壁の高さを調節する ようになっている。また、複数の隔壁は堰頂の一部を切り欠いて、魚の遡行を容 易にする水流を得ている。 Conventionally, dams and weirs installed in rivers have been used for water storage, water damage prevention, etc. In recent years, some dams and weirs that have been designed and constructed have a fishway installed to maintain the fish ecosystem. In some fishways, a long canal made of concrete bypassing a dam or weir is provided from the upstream side to the downstream side, and a plurality of concrete or steel plate partition walls are provided at intervals in the canal. The water level of this fishway is formed by a partition wall in a stepwise manner. Normally, the partition height is adjusted according to the fluctuation of the upstream water level. In addition, a plurality of bulkheads cut out a part of the top of the weir to obtain a water stream that facilitates the retrogression of fish.
【０００３】[0003]
しかしながら、堰を構築するとき、堰の周囲の敷地が狭く魚道を併設すること が出来ない場合、計画予定地を変更しなければならなくなる。また、魚道のない 既存の堰においても、自然環境を優先するようになると、魚道を設けるための堰 の補修工事にも設置スペースの制約を受けるようになる。また、地形の険しい地 域であれば魚道のための資材運搬、整地作業も困難であり費用もかかる。このた め、堰の設置箇所に影響されず、簡単に組み立てられる魚道装置が望まれている 。 However, when constructing a weir, if the site around the weir is small and it is not possible to add a fishway, the planned site will have to be changed. In addition, even if the existing weirs without fishways are given priority to the natural environment, the installation space will be constrained in the repair work of the weirs for the fishways. In addition, it is difficult and costly to transport materials for the fishway and level the land if the area is rugged. Therefore, there is a need for a fishway device that can be easily assembled without being affected by the location of the weir.
【０００４】 本考案は、新たな設置スペースを必要とせず、組み付けが容易な簡易魚道装置 を提供することを目的とする。An object of the present invention is to provide a simple fishway device that does not require a new installation space and is easy to assemble.
【０００５】[0005]
【課題を解決するための手段】 本考案は上記目的を達成するために、固定堰の下流側に設けた護岸壁に、堰頂 部から下流側河床に向けて傾斜させて配置した側板の護岸側縁を前記護岸壁に係 着させ、該側板の水路側縁を連結部材を介して前記護岸壁から離して支持し、前 記護岸壁と前記側板とで形成する溝に間隔を開けて複数の隔壁を設けたことを特 徴とする。[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention aims to achieve the above-mentioned object. On the revetment wall provided on the downstream side of the fixed weir, the revetment of the side plate inclined from the top of the weir toward the downstream riverbed The side edge is attached to the revetment wall, the waterway side edge of the side plate is supported by a connecting member away from the revetment wall, and a plurality of grooves are formed at intervals in the groove formed by the revetment wall and the side plate. It is characterized by the provision of a partition wall.
【０００６】[0006]
本考案の魚道装置は上記のように構成したものであるから、堰頂部からの越流 により前記護岸壁と前記側板とで形成する溝内に水路ができ隔壁によって階段状 の魚道が形成される。また、水量による荷重が側板にかかっても連結部材と接続 されているので溝形状を維持することができる。また、洪水時には隔壁を取外し て護岸壁に側板を沿わせ流水の圧力を回避することができる。 Since the fishway device of the present invention is constructed as described above, a waterway is formed in the groove formed by the revetment wall and the side plate due to the overflow from the weir top, and the staircase-shaped fishway is formed by the partition wall. . Further, even if a load due to the amount of water is applied to the side plate, the groove shape can be maintained because it is connected to the connecting member. In addition, during floods, the bulkheads can be removed and side walls can be placed along the revetment wall to avoid the pressure of running water.
【０００７】[0007]
以下、本考案の実施例を添付図面に基づいて説明する。図１および図２に示す ように、水路１を横断して設けられた固定堰２の下流側には、水路中央に向かっ て傾斜した護岸壁３に魚道装置４が設けられている。すなわち、堰頂部2aから下 流側河床に向けて鋼製の側板５を傾斜させ、側板５の護岸側縁5aはヒンジ６を介 して護岸壁３に取付けられ、側板５の他方の水路側縁5bは一方の縁5aより高くし て連結部材７によって護岸壁３から所定の間隔を開けて取付けられ、護岸壁３と 側板５とでＶ字状の溝を形成している。また、溝内にはゴム製の逆三角形状の隔 壁８が間隔を開けて設けられ階段状の魚道が形成される。この場合、隔壁８の上 辺に凹部を形成しても良い。なお、連結部材７は接続部および中間部にヒンジ９ を有し折り曲げられるようになっている。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 and 2, on the downstream side of the fixed weir 2 provided across the waterway 1, a fishway device 4 is provided on a seawall 3 inclined toward the center of the waterway. That is, the steel side plate 5 is inclined from the weir top part 2a toward the downstream riverbed, and the revetment side edge 5a of the side plate 5 is attached to the revetment wall 3 via the hinge 6, and the other waterway side of the side plate 5 is attached. The edge 5b is made higher than the one edge 5a and is attached to the revetment wall 3 with a predetermined space therebetween by a connecting member 7, and the revetment wall 3 and the side plate 5 form a V-shaped groove. Further, rubber-made inverted triangular partition walls 8 are provided at intervals in the groove to form a staircase-shaped fishway. In this case, a recess may be formed on the upper side of the partition wall 8. The connecting member 7 has a hinge 9 at the connecting portion and an intermediate portion and can be bent.
【０００８】 また、側板５の上側の縁5bにはロープ10が接続され護岸上の巻上げ機11によっ て側板５を護岸側に倒すようになっている。この場合、隔壁８は外され連結部材 ７は折れ曲がるようになっており、図３に示すように、巻上げ機11を操作して側 板５を引上げるようにすると、連結部材７はヒンジ９の箇所で折れ曲がり側板５ が護岸壁３に近接した状態になる。A rope 10 is connected to the upper edge 5b of the side plate 5 so that the side plate 5 is tilted to the bank side by a hoisting machine 11 on the bank. In this case, the partition wall 8 is removed and the connecting member 7 is bent. As shown in FIG. 3, when the hoist 11 is operated to pull up the side plate 5, the connecting member 7 is connected to the hinge 9. The bent side plate 5 becomes close to the seawall 3 at some point.
【０００９】 このように構成した魚道装置４は、固定堰２からの越流水が溝内に流れて魚の 遡行を可能にしている。洪水時には側板５を護岸側に倒して流水の抵抗を少なく し、しかも、装置の破損を防ぐようにし、また、下流域に影響のないようにして いる。なお、隔壁８に護岸壁３と側板５とを接続する連結機構を設ければ連結部 材７は省略することができる。また、護岸壁３を魚道装置４の水路の一部に利用 しているので組み立て部品を少なくし、コストを安くし、魚道装置４の組立作業 を簡易なものにしている。In the fishway device 4 configured in this way, the overflow water from the fixed weir 2 flows into the groove to enable the fish to go back. In the event of a flood, the side plate 5 is tilted toward the revetment side to reduce the resistance to running water, prevent damage to the equipment, and prevent the downstream area from being affected. If the partition wall 8 is provided with a connecting mechanism for connecting the revetment wall 3 and the side plate 5, the connecting member 7 can be omitted. Moreover, since the seawall 3 is used as a part of the waterway of the fishway device 4, the number of parts to be assembled is reduced, the cost is reduced, and the assembling work of the fishway device 4 is simplified.
【００１０】 図４および図５に示す魚道装置４は同様に固定堰２に付設するものであり、側 板５の護岸側の縁5aを護岸壁３に設けた固定金具12で係止し、側板５の護岸側の 縁5aを下端としてＶ字形状の溝を護岸壁３に沿って傾斜して形成するように、連 結部材７で側板５のもう一方の縁5bを高く固定したものである。そして、隔壁８ を配置して階段状魚道を形成している。洪水時には固定金具12から側板５の下縁 5aを取外すことにより、側板５は連結部材７に吊下がり護岸壁３に沿って置かれ ることになる。The fishway device 4 shown in FIGS. 4 and 5 is also attached to the fixed weir 2, and the edge 5a of the side plate 5 on the revetment side is locked by the fixing metal fitting 12 provided on the revetment wall 3, The other edge 5b of the side plate 5 is fixed high by the connecting member 7 so that a V-shaped groove is formed along the revetment wall 3 with the edge 5a on the seawall side of the side plate 5 being the lower end. is there. And the partition wall 8 is arrange | positioned and the staircase-shaped fishway is formed. At the time of flood, by removing the lower edge 5a of the side plate 5 from the fixing bracket 12, the side plate 5 is suspended by the connecting member 7 and placed along the revetment wall 3.
【００１１】 図６および図７に示す魚道装置４の上記のものと異なる箇所は、連結部材７の 護岸壁３に取付ける側を、護岸壁３に設けた固定金具12で係止し、側板５の護岸 側の縁5aをヒンジ６を介して取付けたものである。洪水時には固定金具12から連 結部材７の端部を取外すことになっており、側板５はヒンジ６を中心にして下方 に回転し護岸壁３に沿って置かれることになる。6 and 7 is different from the above-mentioned one, the side of the side plate 5 where the side of the connecting member 7 to be attached to the revetment wall 3 is locked by the fixing metal fitting 12 provided on the revetment wall 3. The edge 5a on the revetment side is attached via a hinge 6. At the time of flood, the end of the connecting member 7 is to be removed from the fixing metal fitting 12, and the side plate 5 rotates downward around the hinge 6 and is placed along the seawall 3.
【００１２】 図８ないし図10に示す魚道装置４は、側板５に隔壁８の一端を接着したもので 護岸壁３に接触する隔壁８の他端は、護岸壁３に固定した支持部材13によって係 止されるようになっている。隔壁８は水流に対して斜めに取付けられ、水流の圧 力によって支持部材13に押付けられている。隔壁８は側板５に接着されているの で、洪水時には隔壁８を取らずに固定金具12から連結部材７の端部を取外すこと ができる。このようにすると、隔壁８は側板５と共に水中に沈むが、側板５に斜 めに取付けられているので、流水の抵抗は隔壁８が直交して接着されているとき よりも軽減され、水流の勢いを阻害しないで済む。The fishway device 4 shown in FIGS. 8 to 10 is one in which one end of a partition wall 8 is adhered to a side plate 5, and the other end of the partition wall 8 that contacts the revetment wall 3 is supported by a support member 13 fixed to the revetment wall 3. It is supposed to be locked. The partition wall 8 is obliquely attached to the water flow and is pressed against the support member 13 by the pressure force of the water flow. Since the partition wall 8 is adhered to the side plate 5, it is possible to remove the end of the connecting member 7 from the fixing bracket 12 without removing the partition wall 8 in case of flood. In this way, the partition wall 8 sinks in the water together with the side plate 5, but since the partition wall 8 is obliquely attached to the side plate 5, the resistance of running water is reduced more than when the partition wall 8 is bonded orthogonally, and the water flow You don't have to slow down.
【００１３】[0013]
本考案は以上のように構成したものであるから、固定堰の下流側の護岸壁を利 用して側板と隔壁とを組み合わせて簡単に魚道を形成することができ、また、側 板と隔壁とを運搬するだけなので各地の魚道のない既存の堰に設置することがで きる。また、設置するときに堰の改修工事の必要がなく地域の環境を維持するこ とができる。 Since the present invention is configured as described above, it is possible to easily form a fishway by combining the side plate and the partition wall by using the revetment wall on the downstream side of the fixed weir, and the side plate and the partition wall. It can be installed in existing weirs without fishways in various places because it only transports and. In addition, the environment of the area can be maintained without the need to repair the weir when installing.
