The difference between the layout of sewage pipes, rainwater pipes and integrated pipe gallery

1. Sewage pipes
The layout of sewage pipelines should be based on topography, drainage system, engineering and hydrogeology, distribution of factories and various buildings, and comprehensive consideration of urban development and other factors related to pipeline engineering. It is best to bury sewage mains in secondary streets. Or places close to sidewalks and green spaces, so as to facilitate the development of construction and daily maintenance work and have less impact on traffic. At the same time, the main sewage pipes should be considered and arranged in combination with the sewage branch lines and sewage sources in the residential area of the street, and the sewage pipes should be considered and arranged. There is a suitable burial depth. Generally speaking, it is appropriate to bury the main pipe at a depth of 3~6m and the branch pipe with a depth of 2~4m.

2. Stormwater pipes
There are two ways to discharge rainwater in cities: underground pipe trenches and above-ground open channels. For urban centers and main streets with dense buildings, complex traffic, and high sanitation standards and safety requirements, underground pipe trenches should be used to drain rainwater; in urban fringe areas and arid areas with little rainfall, in order to reduce investment, it is more appropriate to use open channels.

3. Urban drainage system and comprehensive pipeline engineering
There are generally two forms of urban drainage system, namely ground open channel drainage and underground pipe trench drainage system, which constitute the entire regional drainage system project. However, starting from the development of urban industrial production and people's living needs, the city also covers many underground pipelines and above-ground line projects. Therefore, according to the tasks undertaken by various pipelines, the urban drainage system and various pipeline systems must be comprehensively arranged. , overall arrangement, in order to achieve the unification of technology, economy and use.
