A method of constructing a sliding water gate having a free sliding function and a fish passage is provided to prevent water leakage perfectly, to purify a stream or a river, and to restore an ecosystem by installing a packing member on the guide rail, teetering plates on the sliding water gate, and partition walls inside the sliding water gate. A waterway(11) is formed between both side support structures(10) and a guide rail(12) is installed on the each support structure. A sliding water gate(20) moving along the guide rail is connected with a hydraulic cylinder to be rotated and is opened and closed by the hydraulic cylinder. A packing member(14) is installed on an upper part of the guide rail and contacted with a lower portion of the sliding water gate. Teetering plates(40,50) are installed on both upper and lower portion of the sliding water gate and hinged to a hinge axle(60) respectively. Inside the sliding water gate, zigzag shaped partition walls are formed to be used as a fish passage. |
