「発明の目的」
ａ 産業上の利用分野
本発明はブロツクの水没部分に魚が避難または
棲息する魚巣室部を設けたことを特徴とする魚巣
付Ｌ形水路ブロツク。Detailed Description of the Invention ``Object of the Invention'' a. Field of Industrial Application The present invention relates to an L-shaped waterway with a fish nest, characterized in that a fish nest chamber is provided in a submerged portion of a block for fish to take shelter or live in. Block.
ｂ 従来の技術
従来、断面Ｌ字形状で且つ表面に凹凸がない土
留め用ブロツクを多数個列設して水路を形成した
場合、水没部分がすべてコンクリートブロツクで
覆われ、然も平坦な水路が形成される。b. Conventional technology Conventionally, when a waterway is formed by arranging a large number of earth retaining blocks with an L-shaped cross section and no irregularities on the surface, all the submerged parts are covered with concrete blocks, and yet a flat waterway is created. It is formed.
ｃ 発明が解決しようとする問題点
水路に流速を緩和する形状抵抗面がないため水
流が速くなり、また魚類が避難する場所がなくな
るため下流へ押し流され棲息不能となり、著しく
自然環境を破壊することになる。c Problems to be solved by the invention Water currents become faster because there is no shaped resistance surface to reduce the flow velocity, and fish have no place to take shelter, so they are swept downstream and become unable to live, significantly destroying the natural environment. become.

The lower end of the wall 1 is bent in the lateral direction on the earth retaining side so that the angle of intersection with the rising wall 1 is an acute angle to form the bottom plate 2, and the bent part of the rising wall 1 and the bottom plate 2 is further bent into an earth retaining having the bottom plate 2. An L-shaped water channel block 4 with a fish nest is formed by recessing the rear side and providing a fish nest chamber part 3 on the bottom plate 2, and as shown in FIGS. 4 to 6, the L-shaped water channel block 4 with a fish nest As a modification of the block 4, the lower surface of the fish nest chamber 5 is bulged downward from the bottom plate 2 to form another L-shaped waterway block 6 with a fish nest.
「発明の効果」
本発明に係る魚巣付Ｌ形水路ブロツクを連設し
て水路を形成すると、各魚巣室部の形状抵抗によ
り水路面の粗度係数が大きくなり流速が緩和され
て各魚巣室部に魚類が避難し、或いは棲息するこ
とができ、河川改修によつて一時棲息不能となつ
ていた自然環境を回復することができる。"Effects of the Invention" When a waterway is formed by consecutively connecting the L-shaped waterway blocks with fish nests according to the present invention, the roughness coefficient of the waterway surface increases due to the shape resistance of each fish nest chamber, and the flow velocity is relaxed. Fish can take refuge or live in the fish nest chamber, and river improvement can restore a natural environment that has become temporarily uninhabitable.
而して、魚巣付Ｌ形水路ブロツク４または６の
立上がり壁１を後傾させ且つ、該立上がり壁との
交角が鋭角となるよう土留め側に底板２を水平方
向に設けているため、底板２上に背後土壌の重量
が加わり土圧による転倒を防止して安定よく列設
することができ、また魚巣付Ｌ形水路ブロツク６
の場合は、底板２の下面に魚巣室部５が膨出して
いるため滑り出しに対する抵抗が大となり安定し
た水路を構築できる。 Since the rising wall 1 of the L-shaped channel block 4 or 6 with a fish nest is tilted backwards, and the bottom plate 2 is provided horizontally on the retaining side so that the angle of intersection with the rising wall is an acute angle, The weight of the back soil is added to the bottom plate 2, preventing it from falling over due to earth pressure, making it possible to arrange the blocks in a stable manner.
In this case, since the fish nest chamber 5 bulges out on the lower surface of the bottom plate 2, the resistance against sliding is large and a stable waterway can be constructed.
このように本発明は構造が堅牢で然も大量生産
に適し、魚類の棲息できる水路を容易且つ迅速に
構築できるすぐれた発明である。 As described above, the present invention is an excellent invention that has a robust structure, is suitable for mass production, and can easily and quickly construct waterways in which fish can live.
