摘　　要：通过对单厢式矩形断面、单厢式梯形断面、迷宫式、旋流式等 4种结构形成的沉沙池沉沙效率对比试验表明 ,以迷宫式沉沙池效果最佳 ,平均沉沙效率可达 88.3%。此种结构形式的断面尺寸为 1m、宽 0 .4m ,迷宫室底部比集水渠低 0 .2 m,迷宫分成 5个小厢室 ,每个厢室长 0 .146 m,沉沙池首部的静水池深 0 .2 5Through contrast study on the sand sinking rate of 4 kinds of setting tanks, the results show that labyrinth style settling tank is the best among single echelon settling tank, single square shape settling tank, and rotary setting tank. The labyrinth tank can settle 88.3% of sand. The form of labyrinth tank with a 1×0.4 m 2 scale and with 5 intersection dams. The distance between intersection dams is 0.146 cm. Every dam has a 0.2×0.2 m 2 hole for waterway. The first intersection dam has built a 0.25 m deeper settling basin with which sand can be easily catched in tank.
