【 摘 要 】

In order to improve the drainage system of buildings in China, the drainage system based on pressure pipeline is studied. Firstly, the development background of building drainage in China is described, and the flow algorithm of pressure pipeline is introduced. On this basis, the drainage test of single riser and double riser system is designed. Through comparative analysis of the test, the drainage characteristics of the pipeline drainage system are obtained, and the relevant design methods of the drainage system in buildings are obtained based on the pressure pipeline. The drainage performance of double risers is better than that of single risers. Double risers should be used as much as possible in construction, especially in high-rise buildings. Drainage of high-rise buildings is complex, and large changes in water pressure are easily formed in pipeline, which may damage indoor water-using equipment, make odorous gases in pipelines enter indoors, and destroy living environment. The research results can provide data reference for building drainage design, provide parameter basis for testing standards of drainage capacity of residential drainage system, and improve building drainage system in China.
