What is the knowledge of siphon drainage system?

The siphon drainage system is a drainage system that uses the siphon principle to discharge rainwater, snow water, etc. Compared with the traditional gravity drainage system, this system has more advantages. The following is the information about the siphon drainage system. Introduce.

1. Working principle: Through the special rainwater bucket design, the control of the pipe diameter and height difference can be realized. When the accumulated water in the pipeline continues to increase, a stable siphon flow state can be formed. When the water level reaches the calculated water depth requirement , which can realize the natural drainage of the system.

2. Structural composition: The structure of siphon drainage system includes: siphon rainwater bucket, tail pipe, connecting pipe, suspension pipe, riser pipe, buried pipe, inspection port and fixed and suspension system; among which siphon rainwater Common materials for buckets are aluminum alloy, stainless steel, polyethylene, etc.; pipes used in siphon drainage system should choose cast iron pipes, steel pipes and other pipes.

3. Advantages: Under the condition that the design requirements are met, there is no limit to the number of rainwater buckets, and the flow rate of the rainwater buckets is large and the drainage efficiency is high; the suspension pipe set in the siphon drainage system is in a horizontal state, and no need to set Any slope, the number of risers and buried pipes to be installed is small, which reduces the difficulty of construction and the labor intensity of workers.

4. System inspection method: After the installation of the siphon drainage system pipeline is completed, the drainage pipeline needs to do the irrigation and drainage performance test according to the relevant specifications. The method of meter measurement, the method of calculating the drainage capacity of rainwater by using the actual observation during rainfall, etc.

The normal operation of the siphon drainage system depends on the siphon effect, so ensuring that the technical points of generating and maintaining the siphon effect are fault-free is a necessary condition to ensure the normal and continuous operation of the entire system.
