摘　　要：随着国家节水型城市的建设和水效标识的实施,节水型卫生器具的普及率增高、卫生器具用水量进一步减少,但用水量的减少可能会带来管道堵塞、二次冲洗等问题。为此,以公共卫生间为研究对象,以水效等级为1级的节水型坐便器为试验对象,通过搭建5个节水型坐便器、排水横管长12 m的足尺试验系统,模拟公共卫生间厕位(坐位)是否连续使用、厕位占用比以及排水横管坡度等对塑料排水横管输送性能的影响。结果表明,为了保证DN110、PVC-U塑料横管的输送性能,公共卫生间的排水横管坡度宜不小于0.012。The construction of national water‑saving city and the implementation of water efficiency label increase the popularity rate of water‑saving sanitary appliances,and further decrease the water consumption of sanitary appliances.However,the reduction of water consumption may lead to problems such as pipeline blockage and secondary flushing.This paper constructed a full‑scale test system consisting of five water‑saving toilets with water efficiency grade of 1 and a horizontal drainage pipe with length of 12 m in a public toilet,and simulated the effects of scenarios such as the continuous use of the toilet seat(or not),the occupancy ratio of the toilet and the slope of the horizontal drainage pipe on the conveying performance of the plastic horizontal drainage pipe.The slope of the horizontal drainage pipes in public toilets should not be less than 0.012 in order to ensure the conveying performance of DN110 and PVC‑U plastic horizontal pipes.
