Abstract: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.
