Siphon drainage pipe

The siphon roof rainwater discharge system is a new type of rainwater discharge system that uses a siphon rainwater hopper that can isolate air and precise hydraulic balance calculation of pipelines. Relying on the potential energy of the building, rainwater flows through a closed pipeline system to form a full pipe flow, and falls outside the riser to produce siphon effect, quickly discharging rainwater from the roof.

The siphon roof rainwater drainage system is one of the most advanced roof rainwater drainage systems in the world today. This system has a history of nearly 40 years and is widely used in large-span and structurally complex roofs such as large factories, exhibition halls, airports, sports fields, and high-rise buildings. Due to the current design focus on factors such as the aesthetic appearance of buildings, ease of construction, and increasing the usable area and lifespan of buildings, traditional gravity based rainwater systems are becoming increasingly inadequate and cannot meet the increasingly advanced design concepts; The replaced siphon rainwater system not only solves some design difficulties that traditional gravity rainwater systems cannot achieve, but also has advantages in saving pipes and construction volume that traditional systems cannot match.

Application scope:

Residential, hospital, office building, standardized workshop, villa, hotel, theater, exhibition center and other high-end construction projects.

System principle:

The siphon roof rainwater drainage system utilizes the Bernoulli equation. Using meticulous calculations and fully utilizing the energy generated by the height difference between the roof and the ground to form a siphon effect, the system quickly discharges rainwater under full flow conditions.
