Roof unpowered siphon drainage method and system
The invention discloses a roof unpowered siphon drainage method. The roof unpowered siphon drainage method comprises the following steps that firstly, the minimum pipe diameter and the spiral angle of a pipe are calculated; secondly, a gutter with a slope is constructed on the building roof; thirdly, a first drainage hopper, a second drainage hopper and at least one third drainage hopper are installed in the gutter; 4, predicting the rainfall at the target moment; 5, selecting an execution strategy; and step six, the sampling period T is spaced, and the step four to the step five are repeated. The invention further comprises the roof unpowered siphon drainage system. According to the method, economic and balance calculation is carried out on system pipelines, the safety of roof drainage can be improved, pipes with inclined threads on the inner walls are constructed in a manual pipe roughening mode, different numbers of rainwater hoppers are continuously increased and selectively opened according to different rainfall capacities in the rainfall process, it is ensured that complete siphon full pipe flow is formed in the pipelines, and the drainage safety of the roof is improved. And system pipeline turbulent fluctuation and noise caused by the gas-liquid two-phase flow phenomenon are reduced.
本发明公开了一种屋面无动力虹吸排水方法，包括以下步骤：步骤一、计算管材的最小管径和螺旋角度；步骤二、在建筑屋面构建具有斜坡的天沟；步骤三、在天沟内安装第一排水斗、第二排水斗和至少一个第三排水斗；步骤四、预测目标时刻降雨量；步骤五、选择执行策略；步骤六、间隔采样周期T，重复步骤四至步骤五。本发明还包括一种屋面无动力虹吸排水系统。本发明不仅对系统管道进行了经济和平衡计算，还能提高屋面排水的安全性，以人工加糙管的形式构建内壁具有倾斜螺纹的管材，根据降雨过程中降雨量的不同，持续增大，选择性的打开不同数量的雨水斗，确保管道形成完全的虹吸满管流，降低气液两相流现象带来的系统管道紊动和噪声。
