In modern society, along with the acceleration of urbanization, the production of sewage, a category of pollution source, is increasing. Urban sewage is the wastewater discharged into the municipal sewage system, which mainly includes three parts: domestic sewage, industrial sewage and rainwater. Among them, domestic sewage is a general term for all kinds of sewage produced in human's daily life, and as common municipal sewage, it is closely related to our life. Sewage will pollute our environment and produce water pollution, air pollution and soil pollution, so sewage cannot be directly discharged into the natural environment. So how should domestic sewage be collected and treated?

In the context of continuous development of social and economic construction, the pace of urbanization in China is also advancing. With the improvement of urban infrastructure, the utilization of urban underground space has become more and more frequent. In order to effectively improve the utilization of urban underground space and avoid conflicts between various engineering pipelines, it is necessary to construct urban underground integrated pipeline corridor. This paper will start from the advantages, classification and shortcomings of the urban underground integrated pipe corridor project, and elaborate its construction technology.
