PURPOSE:To effectively utilizing the excessive water in a high water season so as to increase the output of a waterwheel by, without ineffectively discharging said water, by jetting-out the stored water in a pool toward the downstream in an outlet pipe on the downstream of a waterwheel. CONSTITUTION:A jet injection port 5 for jetting-out the stored water in a pool towards the downstream is formed onto an outlet pipe 4 on the downstream of a waterwheel 3, and a water feeding pipe 6 having a gate 7 is connected between the jet injection port 5 and the pool. Therefore, when the gate 7 is opened in a high-water season, the excessive water is jetted into the outlet pipe from the jet injection port 5, and accelerates the water stream, and the output of the waterwheel can be increased. |
