Storm drainage pipe refers to a pipe system used for rainwater discharge and drainage. It is mainly composed of gutters, joints, pipes, etc., arranged inside or outside the building, and used to discharge rainwater from the inside or outside of the building to the sewer or other drainage system.
Function
1. Drainage: The main function of a Storm drainage pipe is to drain water, collect rainwater on the roof and the ground, and transfer it to the sewer or other drainage devices. Through the rainwater pipe, rainwater can be prevented from accumulating on the roof and the ground, causing damage or leakage.
2. Prevent flooding: Under the action of the rainwater pipe, the soil around the building will not be soaked by a large amount of rainwater, avoiding structural damage to the building and foundation settlement.
3. Collect tap water: In some places, due to insufficient water sources and other reasons, the supply of tap water may be interrupted, and at this time the outlet of the rainwater pipe in the building becomes an important source for collecting tap water. At this time, the collected rainwater only needs to be simply purified to become a source of drinking water.
What material is Storm drainage pipe made of
It is better to use PE pipes for rainwater discharge.
PE pipe, that is, a high-density polyethylene pipe, has high corrosion resistance and wear resistance, good flexibility, is not easy to break and has a long service life. This kind of pipe is widely used in building drainage, municipal pipe network construction, chemical industry, and other sewage drainage. The advantages of PE pipe include corrosion resistance, good environmental performance, and can meet the drainage and sewage needs of different industries. Therefore, PE pipe is the ideal choice for rainwater drainage, to ensure the normal operation of the drainage system
Storm drainage pipe In addition to PE pipe can also be made of PVC pipe. PVC pipe because of its lightweight, corrosion resistance, convenient construction, and other advantages, is generally used for low pressure, low temperature, small diameter rain, and sewage pipes. PVC pipe has good corrosion resistance and high-temperature resistance, making it suitable for home and some engineering uses.
Installation specifications
Size selection: The size of a storm drainage pipe needs to be based on the drainage volume, rainfall, and other conditions of the place of use. It is recommended to choose a larger size for urban underground rainwater pipes, preferably a size that can be entered for easy maintenance. Conventional specifications include 50mm, 75mm, 90mm, 110mm, etc. The length of the pipe is generally 4m or 6m. Other lengths can be negotiated by both parties. The specifications of the rainwater pipe are φ20, φ25, φ32, φ40, φ50, φ63, φ75, φ90, φ110, φ125, φ140, φ160, φ180, φ200, φ225, etc.
In urban construction and management, the Storm drainage pipe system is an indispensable part. It can not only protect buildings from damage but also improve the environmental quality of the city and the quality of life of residents. Through scientific and reasonable planning and implementation, the rainwater drainage system can also promote the natural circulation of rainwater, reduce the risk of urban floods, and alleviate the problem of urban water shortage to a certain extent.
