众多的套三住宅中,卫生间排水立管一般设在图1中右侧。立管由于受温度变化变形,极易引起防水层与立管脱落而失效,造成渗漏。我们在相邻户之间增设管道井≥70厘米。排水立管和给水立管均安装在图2井内,这样既减少了卫生间、厨房间现浇平台穿管孔洞造成的渗漏,又便于安装、检修和收水费人员的工作。各住户的太阳能立管均可安装在管道并内,防止抽气孔堵塞失去作用。消除了浴缸与轴
In many sets of three houses, the toilet drainage risers are generally located on the right side of Figure 1. The riser is deformed due to temperature changes, which can easily cause the waterproof layer and riser to fall off and fail, resulting in leakage. We added more than 70 cm of pipe wells between adjacent households. Both the drainage riser and the water supply riser are installed in the well of Figure 2, which not only reduces the leakage caused by the holes in the cast-in-place platform between the toilet and the kitchen, but also facilitates the installation, maintenance and the work of the water collecting personnel. The solar risers of all households can be installed inside the pipeline to prevent the plugging of the suction holes from functioning. Eliminate bathtubs and shafts
