Background technique

The siphon drainage system is widely used in large-scale roof buildings, such as gymnasiums, factory buildings and other roofs with large spans and complex structures. It is an effective way to solve roof drainage. The traditional siphon drainage system uses the height of the building roof to make the rainwater have potential energy. When the rainwater continuously flows through the rainwater suspension pipe and transfers to the rainwater standpipe, the pipe generates the maximum negative pressure. The roof rainwater can be absorbed by the negative pressure in the pipe. Higher flow rates are vented to the outside.

The setting and installation of suspension pipes are an important part of the traditional siphon drainage system. However, installing suspension pipes in buildings will bring certain difficulties to the installation and construction.
