厨房、卫生间给排水支管的传统设计多采取明敷设,特别是排水支管为隔层敷设安装,既影响了厨房、卫生间的使用效果,又留下潜在隐患,同时也给施工和住户带来不便。针对上述缺点,为减少住户入住后的二次装修费用,避免乱打乱凿,确保结构安全以及减小施工难度,杜绝管口周边渗漏等弊病,现提出将厨房、卫生间给排水支管改为暗敷设,具体作法如下。 The traditional design of the water supply and drainage pipes in the kitchen and bathroom should be more clearly laid out. In particular, the drainage pipes should be laid and installed for the partitions, which not only affects the use effect of the kitchen and bathroom, but also poses potential hidden dangers. Meanwhile, it also brings inconvenience to the construction and households. In response to the above shortcomings, in order to reduce the cost of second renovations after occupants’ stay, to avoid indiscriminate chipping, to ensure structural safety, to reduce the difficulty of construction and to eliminate the leakage around the nozzle, it is proposed to change the water supply and drainage pipes of the kitchen and toilet into Dark laying, the specific practices are as follows.
