FISHWAY BLOCK, FISHWAY STRUCTURE BY MEANS OF FISHWAY BLOCKS, CONSTRUCTION METHOD OF FISHWAY STRUCTURE, AND CONNECTION STRUCTURE FOR CONNECTING FISHWAY STRUCTURE WITH THE OTHER WATERWAY STRUCTURE INCLUDING THE FISHWAY STRUCTURE
PURPOSE: To free the movement of fish and facilitate the repair of fishways by adjacently arranging a plurality of fishway block bodies, and by mutually communicating the water flow passages of the adjacent fishway block bodies. ;CONSTITUTION: Fishway block bodies 1 consisting of bottom structural parts 10 and erected structural parts 9 that have been erected upward therefrom are formed, and water stagnant parts 17 are provided in the appropriate positions thereof. Flowing water inlet/outlet parts 21 are provided to the side peripheral parts of the fishway block bodies 1, and they are communicated with the water stagnant parts 17. A plurality of fishway block bodies are adjacently juxtaposed for constituting fishway structures 2, and further a plurality of fishway structures 2 are juxtaposed. In this case, a communicating flow passage is formed between the water flow passage of the respective fishway block bodies 1 and the water flow passage of the other adjacent fishway block bodies 1. Out of the foot protection blocks being used in the floor protection structural part, necessary parts are properly replaced with these fishway blocks.;COPYRIGHT: (C)1994,JPO&Japio
