After the formwork is supported by civil engineering and the bottom reinforcement is tied, the installer will locate it on site, fix the embedded parts on the bottom formwork with appropriate round nails through the fixing holes on the connecting bracket, and then cover the top opening with a pipe cap to prevent concrete mortar and sundries from falling into it; When pouring concrete, installation workers should be on-site supervision, and civil workers should also cooperate closely. If the embedded parts are inclined, they should be handled in time. After civil form removal, before the next working procedure, the protruding part of the round nail fixing the embedded parts should be removed, and the removed part should be painted with antirust paint.
Water-stop is mainly used in toilets, kitchens, balconies, terraces and other places where pipes pass through the floor, mainly for drainage pipes. A new technology of embedding casing in water-stop joint is adopted, which is mainly composed of pipe body, water-stop wing ring, bottom double-layer plug-in socket, fixed bracket and pipe cap.
