摘　　要：塑料管以其诸多优越性在建筑排水。程中得到愈来愈广泛的应用，然而塑料管因材料本身、设计方法等因素的影响，实际工程中经常发生底层排水水封破坏问题。从分析排水管道流态和塑料管特点出发，通过终限流速的分析，得出了水封破坏的原因，提出了保护水封的相应措施，并对塑料排水立管排水能力的确定提出了探讨性意见。Plastics sewer is more and more widely used in building sewage engineeringfor a lot of advantages of itself. But as influences of plastics sewer material and desingningmethods, water seal destruction in first floor often takes place in practice engineering. Byanalysis of flow forms,characteristic of plastics sewer and terminal velocity, water seal destroyed reasons are found. The paper also puts forward measurements against water sealkeeping and makes suggesting opinions for fixing discharge capacity of vertical plastics sewer.
