- Abstract:
- According to the characteristics of hospital drainage, this paper puts forward the principles of floor drain setting, which should not only meet the functional requirements, but also meet the requirements of environmental sanitation and safety. In addition, the paper also gives some suggestions on the suitable place and position of floor drain for hospital drainage. This paper discusses the selection of floor drain, the arrangement of floor drain pipe and the setting requirements of indirect drainage, and points out the problems needing attention and the methods to deal with the reasonable setting of floor drain. This paper analyzes the problems of water seal protection and floor drain flow, and clarifies the importance and necessity of water seal. It compares the requirements of different standards for floor drain discharge. This paper suggests that there should be as little floor drain as possible in hospital drainage to reduce cross-infection. When it is necessary to set up floor drain, the design can adopt the drainage mode of trap and straight floor drain whithout water seal.
