在排水管道系统中,通常采用圆形断面的管道,混凝土管、钢筋混凝土管、陶土管、石棉水泥管等均属于这种断面形式。根据给水排水工程设计规范对排水管渠中液流充满度(α=h/d)的规定:1.污水管道应按非满流进行计算(即α=h/d<1);2.雨水管道、合流管道、以及某些生产废水管道,可以按满流进行计算(即α=h/d=1)。对于这类充满度小于1或等于1的排水管道,和液体
In the sewer system, circular cross-section pipes are generally used. Concrete pipes, reinforced concrete pipes, clay pipes, asbestos cement pipes, etc., belong to this type of section. According to the design rules for water supply and drainage engineering, the fullness of flow in the drainage canal (α=h/d): 1. The sewage pipeline shall be calculated according to non-full flow (ie α=h/d<1); 2. Rainwater Pipelines, converging pipes, and some production wastewater pipes can be calculated as full flow (ie, α=h/d=1). For such drain pipes with fullness less than 1 or equal to 1, and liquids
