卫生间的标高是个老问题了。为什么很多卫生间(包括厕所)排水不畅,地漏偏高,主要有以下几个原因:一、对图纸未仔细审阅,按习惯做法行事;二、建设单位(个别的)在装修卫生间地面时才提出变更面层;三、未计算卫生间的流水坡度。前两个原因都好解决,容易疏忽的是第三个原因,尤其是初学施工的人员。 The elevation of the bathroom is an old problem. Why do many toilets (including toilets) have poor drainage and high floor drain? These are mainly due to the following reasons: First, the drawings have not been carefully reviewed and they have been followed in accordance with customary practices. Second, the construction units (individual) have only proposed renovation of the bathroom floor. Change the surface; Third, did not calculate the bathroom water slope. The first two reasons are all well resolved. It is easy to neglect the third reason, especially for beginners.
