A small bulkhead 2D is stretched at the left end of a block body in which the front and rear walls 2B and 2G are connected in a cross-sectional shape on the front and rear edges of the block body,
In addition, a beam-shaped notch 2D' is formed on the front wall 2B side at the upper edge of this small partition wall 2D, and a water inlet 2E is opened at the lower part of the septum wall, and the right opening of the upper air block body. A connecting receiving part 2F is formed in the upper left corner of the front and rear walls 2B and 2C, and an engaging notch 2B is formed in the upper left corner of the front and rear walls 2B and 2C.
', 2C' are formed on the lower surface of the bottom plate 2A, and an engagement step 2A' is formed on the lower surface of the bottom plate 2A, and a lighting opening 2C'' is formed on the rear wall 2C.
また、上記■型ブロック単体３は平面方形の底板３Ａの
前後縁部に前後壁３Ｂ、３Ｃを断面し状に連設せしめた
ブロック体における左方端面には小隔壁３Ｄを設け、当
該中隔壁３Ｄの上縁における前壁３Ｂ側にはり状の切欠

通水口３Ｅが開口され、上記ブロック単体の右方端面に
は右方壁３Ｆが張設され、かつ上記前後壁３Ｂ、３Ｃの
左上刃部には保合用切欠き３Ｂ’、 ３Ｃ’が形成さ
れると共に上記前壁３Ｂには連結用開口部３Ｂ″がまた
後壁３Ｃには採光用開口部３０″が形成され、かつ、上
記底板３Ａの下面には係合用段部３Ａ’が形成されてい
る。In addition, the above-mentioned ■-shaped block unit 3 has a small partition wall 3D on the left end surface of the block body in which the front and rear walls 3B and 3C are connected in a cross-sectional manner at the front and rear edges of the bottom plate 3A having a rectangular plane. A beam-shaped notch 3D' is formed on the front wall 3B side at the upper edge of 3D, and a water inlet 3E is opened at the lower part of the septal wall, and the right end surface of the block alone is provided with the right wall 3F. are stretched, and retaining notches 3B' and 3C' are formed in the upper left blade parts of the front and rear walls 3B and 3C, and a connecting opening 3B'' is formed in the front wall 3B and in the rear wall 3C. A lighting opening 30'' is formed, and an engagement step 3A' is formed on the lower surface of the bottom plate 3A.
そして、上記Ｉ型ブロック単体２と■型ブロック単体３
とは当該■型ブロック単体２の左方端部分を上記■型ブ
ロック単体３の連結用開口部３Ｂ″に嵌合した状態で、
平面うずまき状に連結されている。Then, the above-mentioned I type block single unit 2 and ■ type block single unit 3
means that when the left end portion of the ■-type block unit 2 is fitted into the connecting opening 3B'' of the ■-type block unit 3,
They are connected in a planar spiral shape.
このようにして、■型、■型の各ブロック単体４個の連
結組合せで一段階となり、流水は一巡して落差は１．８
７７Ｌ程度となる。In this way, one stage is formed by connecting and combining four individual blocks of each type ■ and ■ type, and the running water goes around once and the head is 1.8.
It will be about 77L.
そして、この連結に際しては上下左右に必要な個所をボ
ルト締めまたは溶接構造その他の緊結方法で緊密に連結
して一体化を図り、個体間の接合面には特殊ゴム製品を
使用して漏水を防止されている。When making this connection, the necessary parts on the top, bottom, left and right sides are tightly connected using bolts, welding structures, or other fastening methods to achieve integration, and special rubber products are used on the joint surfaces between the pieces to prevent water leakage. has been done.
本案のものは上述の如く構成されているから、Ａ 工場
における品質管理を充分にでき品質良好な製品を得るこ
とができる。Since the present invention is constructed as described above, quality control at factory A can be carried out sufficiently and products of good quality can be obtained.
Ｂ 機械による積重ね作業が容易であり特殊な技術は要
しない。B: Mechanical stacking work is easy and no special skills are required.
従って工期を短縮することができる。Therefore, the construction period can be shortened.
Ｃ直線型魚道に比して用地が小である。C The land area is smaller than the straight fish ladder.
Ｄ 上方に位置するブロック単体の係合段部が下方に位
置するブロック単体の上面開口部に嵌合するから横方向
への滑りに強い。D: Resistant to lateral slippage because the engagement step of the upper block fits into the upper opening of the lower block.
Ｅ ３０ｍ〜５α肌の高さの魚道の建設を可能にする
構造となっている。E The structure allows for the construction of a fishway with a height of 30m to 5α.
Ｆ 採光用開口部を設けたから、魚類のそ上を容易にす
る。F. The opening for daylighting makes it easier for fish to climb up.
など、数多くの利点を有する有用な考案と言うべきもの
である。This is a useful device with many advantages.
