1 Make a hole in the floor slab.
2. Before the installation of the drainage pipeline, the civil engineering negotiation shall be required to pay off, find the size of the dump of sanitary appliances and the height of the rejection, install the trunk pipe, the riser pipe to the branch pipe in turn, and verify whether the coordinates are accurate again before the civil engineering plugging the floor hole. >>>More
It's probably relatively simple.
It could be that you just do what is prescribed. >>>More
1) base treatment, first the embedded nozzle periphery is not dense concrete carefully chiseled off, the thickness of chiseling is about one-third of the plate thickness, when chiseling the caisson concrete floor slab to be inclined plane chiseling, careful construction, can not destroy the concrete floor slab that most of the pit is retained below, then rinse the chiseled part with clean water, and the base cleaning must ensure that it is clean, no debris such as broken concrete; >>>More
