SAND REMOVING/WATER DISCHARGING TANK
To stabilize a flow rate for maintaining a river and to eliminate a periodical sediment removal work.SOLUTION: A sand removing/water discharging tank 5 comprises: a bottom portion 11; and wall portions 12 to 15 formed integrally with the bottom portion 11 and erected from a peripheral edge of the bottom portion 11. In the wall portion 12, an inlet 12A making water taken from a river flow-in is formed. In the wall portion 13, an outlet 13A making water flowing-in through the inlet flow out toward a conduit is formed. In the bottom portion 11, a sand removing/water discharging port 11A is formed. In the bottom portion 11, slope portions 18, 19 comprising a sloped face being sloped downward toward the sand removing/water discharging port 11A are formed. The sand removing/water discharging port is connected to the river by piping.SELECTED DRAWING: Figure 3
【課題】河川維持流量を安定させ，定期的な土砂の除去作業を不要とする。【解決手段】排砂放水槽５は，底部11と，底部11と一体に形成されて底部11の周縁から立ち上がる壁部12～15とを備えている。壁部12には河川から取水された水を流入させる流入口12Ａが形成され，壁部13には流入口から流入した水を導水管に向けて流出させる流出口13Ａが形成されている。底部11には排砂放水口11Ａがあけられており，この底部11には，上記排砂放水口11Ａに向かって下向きに傾斜する傾斜面を備える傾斜部18，19が形成されている。排砂放水口は配管によって上記河川につなげられる。【選択図】図３
