卫生间地面向地漏处排水坡度一般为2%~3%,卫生间的地面标高设计应比室内低20~50mm。 卫生间回填、找平时,应以地漏为中心向四面方向辐射,找准坡度,用刮尺刮平,抹面要求平整,表面无坑、无缝隙,不起沙,以不积水为准。 不止是地面需要坡度,在水管安装的时候也要注意水管的坡度,给水横管以0.002~0.005的坡度坡向泄水装置或配水点,给水引入管应有不小于0.003的坡度坡向室外给水管的。
The drainage slope from the toilet floor to the floor drain is generally 2% ~ 3%, and the design of the toilet floor elevation should be 20 ~ 50mm lower than that of the indoor For the backfilling and leveling of toilet, the floor drain shall be used as the center to radiate in all directions, and the gradient shall be found out. The scraper shall be used to level the surface. The surface shall be free of pit, gap, sand and ponding Not only the slope is required for the ground, but also the slope of the water pipe shall be paid attention to when the water pipe is installed. The horizontal water supply pipe shall slope to the discharge device or distribution point with a slope of 0.002-0.005, and the water supply inlet pipe shall slope to the outdoor water supply pipe with a slope of no less than 0.003.
