摘要
地漏是连接排水管道系统与室内空气的重要接口,作为住宅排水系统的重要组成部分,其性能直接影响室内空气质量.为了防止排水系统产生臭气,有必要对地漏水封进行安全性测试.等比例搭建2层卫生间,以模拟别墅、复式楼建筑的排水情况,探究不同种类地漏在不同安装位置和不同排水情形下的水封保持能力.研究认为,在别墅及复式楼,建议尽量选用带水封的地漏,且原始水封高度应大于或等于50 mm,将其安装在DN110横干管更为安全可靠,若难以实施,应将其安装在横支管末端,并遵循《地漏》(GB/T 27710-2011)规范要求.
Abstract
Floor drain is an important connection between the drainage system and indoor air.As an important part of the residential drainage system,the performance of floor drain directly affects the quality of indoor air.In order to ensure no odor produced in the drainage system,it is necessary to carry out safety testing of trap seal.A two-story bathroom was built to simulate the drainage at villas and duplex houses.The trap seal capacity of different types of floor drains at different installation locations and under different drainage conditions was explored.It was suggested that floor drains with trap seals should be selected for the villas and duplex houses,the original seal height should be greater than or equal to 50 mm,and it should be installed in DN110 horizontal pipes.If it was difficult to implement,it should be installed in the end of horizontal branch,and follow the requirements in the Floor Drain (GB/T 27710-2011).
