SAND SEDIMENTATION POND
To provide a sand sedimentation pond which can collect sands sedimented on a bottom surface in a groove without leaving the same.SOLUTION: A sand sedimentation pond 2 which causes received water to flow down in an orthogonal direction orthogonal to a pond width direction between a left side wall Wa and a right side wall Wb which constitute end faces in the pond width direction, and causes sands contained in water to sediment. The sand sedimentation pond has: an upstream side first main trough 815 and an upstream side second main trough 816 which are provided on a pond bottom, and respectively extend in the orthogonal direction at an interval therebetween in the pond width direction; and a projection wall 10 which is formed between the upstream side first main trough 815 and the upstream side second main trough 816, and projects upward from the pond bottom. At a portion of the pond bottom between the upstream side first main trough 815 and the upstream side second main trough 816 excluding an area in which the projection wall 10 is provided, a ridge line part 731 which extends along the orthogonal direction, a first connection surface 732 which connects the ridge line part 731 and the upstream side first main trough 815, and a second connection surface 733 which connects the ridge line part 731 and the upstream side second main trough 816 are formed.SELECTED DRAWING: Figure 3
【課題】底面に沈降した砂を残留させることなく溝内に集めることができる沈砂池を提供する。【解決手段】池幅方向の端面を構成する左側壁Ｗａと右側壁Ｗｂの間で、受け入れた水を池幅方向と直交する直交方向に流下させ水に含まれている砂を沈降させる沈砂池２において、池底部に設けられ、池幅方向に間隔をあけて、直交方向にそれぞれ延在した上流側第１主トラフ８１５および上流側第２主トラフ８１６と、上流側第１主トラフ８１５と上流側第２主トラフ８１６の間に形成され、池底部から上方に突出した突出壁１０とを有し、池底部のうち上流側第１主トラフ８１５と上流側第２主トラフ８１６の間であって突出壁１０が設けられた領域を除いた部分に、直交方向に沿って延在する稜線部７３１と、稜線部７３１と上流側第１主トラフ８１５とを接続する第１接続面７３２と、稜線部７３１と上流側第２主トラフ８１６とを接続する第２接続面７３３とが形成されている【選択図】図３
