双斗式虹吸排水系统泄流量理论与实验研究

Theoretical and Experimental Study on Discharge of Double-outlet Siphonic Drainage System

利用伯努利方程结合管路串并联理论对双斗式虹吸雨水排水系统进行理论公式推导,得到双斗式系统泄流量的计算式。搭建双斗虹吸式雨水排水系统实验台,对比实验结果与理论计算结果,得到了较好的一致性;双斗式虹吸系统中存在近排水立管处的雨水斗泄流量较大的规律。

Based on the Bernoulli equation combined with the series parallel theory of pipelines, the theoretical formula of the double-outlet siphonic drainage system is deduced, and the calculation formula for the discharge capacity of the double-outlet system is obtained. Good consistency is obtained by building a double-outlet siphonic rainwater drainage system test bed, and comparing experimental results with theoretical calculation results. In the double-outlet siphonic drainage system, there is a regularity of the higher discharge flow rate of the outlet which near the vertical drainage pipe.
