虹吸雨排系统在商业综合体种植屋面的应用

Application of Siphon Rainwater Drainage System in Planted Roof of Commercial Complex

上海地区降雨量大,种植屋面结构荷载大,屋面雨水无法迅速排走,严重影响植物的正常生长。如果存在渗漏等情况,会给经营者带来经济损失,严重者还会因为负荷增加导致结构坍塌,从而造成重大人身和财产损失。通过从设计、材料选择、施工节点等方面介绍种植屋面虹吸雨排系统的关键技术要点,保证虹吸雨排的施工质量和应用效果,为后续同类型项目提供指导和借鉴。

The roof rainwater is hard to quickly discharge because of heavy rainfall in Shanghai and large load of planted roof structure,which seriously affects the normal growth of plants.The leakage and other conditions if existing will bring great economic losses to the operators,and if seriously will lead to the structural collapse because of the increase in load so as to cause the heavy personal and property losses.The key technical points of siphon rainwater drainage system for planted roof are introduced from the aspects of design,material selection and construction nodes,and the construction quality and application effect of siphon rainwater drainage are ensured,which provide the guidance and reference for the follow-up similar projects.
