摘　　要：为满足老年人在既有住宅中设置靠近卧室或床边且具有排水功能的介护坐便器的需求,提出采用压力流的排水方式,通过小型污物提升装置泵送污水至横支管系统。通过等比例试验模型,采用不同卫生器具组合排水的方式,探究压力流排水的介护坐便器对排水系统横支管的影响。结果表明,对于既有排水系统横支管,介护坐便器管道系统靠近立管端接入所产生的影响接近于不接入工况,能够满足介护坐便器的管道改造需求。To satisfy the seniors＇ requirements on functional drainage toilets which were set near ihe bedroom or at bedside in the residence, it was proposed to use a pressurized drainage pipe, by pum- ping sewage into a horizontal pipe system using a small lifting device. Multiple sanitary appliances and combinations were tested to explore the pressure fluctuation effects of the nursing toilet on the drainage pipe system through full-scale tests. The resuhs showed little influence on the existing horizontal＇ branch when the nursing toilet drainage pipe system connection was near the riser; therefore, it met the drainage pipe system＇ s requirement for the reconstruction.
