PROBLEM TO BE SOLVED: To provide a sand sedimentation pond suitable for a comparatively small site area such as a hydraulic power plant.SOLUTION: A vertical sand sedimentation pond includes: a sand sedimentation tank having a cylindrical inner surface with a water intake port and a discharge port; a water intake flow channel connected to the sand sedimentation tank via the water intake port; and a discharge flow channel connected to the sand sedimentation tank via the discharge port. The water intake port is disposed at a position lower than the discharge port. The center axis line of the water intake port extends along the tangential direction of the circular cross section of the sand sedimentation tank. Water introduced to the sand sedimentation tank via the water intake port becomes a swirl flow and is discharged to the discharge port.
【課題】小型の水力発電所のように比較的敷地が狭い場合に好適な沈砂池を提供する。【解決手段】立型沈砂池は、取水口及び排出口を有する円筒状内面を備えた沈砂槽と、前記取水口を介して前記沈砂槽に接続された取水流路と、前記排出口を介して前記沈砂槽に接続された排出流路と、を有し、前記取水口は前記排出口より低い位置に設けられ、前記取水流路の中心軸線は前記沈砂槽の円形断面の接線方向に沿って延びており、前記取水口を介して前記沈砂槽に導かれた水は旋回流となって前記排出口に排出される。【選択図】 図５
