摘要

The artificial aquatic block for fish movement in the river underwater section according to the present invention allows the fish in the river to move freely upstream and downstream beyond the underwater beam, and can also create a nature-friendly environment suitable for fish habitat. It is intended to be easily constructed according to the height of the underwater beam.;Artificial aquatic block for fish movement of the river submerged section according to the present invention is made of a different length, a plurality of lower support plates (10, 20, 30) stacked in a stairway form from the bottom to the downstream side of the submersible (1) )Wow; A support part 41 is formed at the bottom of the bottom beam of the submersible beam or on the upper surface of the lower support plate, and a connection part 42 connected to the support of the other lower installation frame is provided at the top of the rear end of the lower support plate. A plurality of lower installation frames 40 installed in a stepped form along the shape; The upper fastening frame 50 is provided with an inserting portion 52 at the lower part of the myelin sheath assembly rail 51 at the upper part, and the fitting portion protruding in the middle of the upper surface of the lower installation frame is connected to the inserting portion and fastened by the fastening pins 53. and; A myelin sheath 60 which is detachably coupled to the upper fastening frame and in which myelin F is planted; Then, it is composed of a natural stone 70 placed around the water frame.
