It cannot be used as a water stopper directly.
Generally, the water stop design does not specify what needs to be used. It should be remembered only if the design is clear, otherwise it is a construction measure.
The water stop section is mainly for waterproofing, and the casing is mainly for reserved pipeline construction (the function of passing through the pipeline).
From the perspective of construction examples, the embedded casing currently used in construction is the so-called finished casing, which is actually a water stop. The difference between it and casing is that the casing mainly functions A reserved hole is used. After the pipeline is installed, secondary hanging formwork needs to be carried out. In the past construction, bathroom leakage was basically caused by secondary hanging formwork, so the water stop section is what we often call the finished casing. , it is directly fixed on the formwork during the pre-embedding process, and there are sockets on the top and bottom. During installation, you only need to apply the corresponding glue on the corresponding pipes and insert them, avoiding the hidden dangers of secondary lifting of the formwork and leakage.
