This product is preset above the formwork before cast-in-place construction in the early civil construction stage of the project. It is pre-buried in the floor with concrete to facilitate the later installation of drainage risers. It replaces the traditional method of reserving holes and avoids leakage caused by improper installation. This product is made of This product is pre-positioned above the formwork before the cast-in-place construction in the early stage of civil engineering construction. The concrete embeds it in the floor slab to facilitate the later installation of the drainage riser, replacing the traditional method of reserving holes and avoiding the problem of leakage caused by improper installation. This product is made of gray cast iron and consists of the main body of the pipe fitting, a special adjustable centering flange, a waterproof wing ring, staggered positioning lugs and screws. In the later stage, it is connected by the method of connecting the lower fl
Installation method: Before the cast-in-place construction, fix the pre-buried sleeve on the bottom formwork with screws or nails through the positioning lugs (note: when used with the pre-buried floor drain, it is fixed to the formwork in a staggered manner with the positioning lugs of the pre-buried floor drain) to ensure that the position is fixed and does not shift during the cast-in-place construction.
Precautions and fault-tolerance adjustment: When fixing to the formwork, it is necessary to pay attention to fixing the pre-buried sleeve at the same position on each layer of the formwork, and try to keep the vertical consistency of the positions of the pre-buried sleeves on each floor. At the same time, in order to prevent the vertical position error generated during the pre-buried stage in the later installation stage for this product, the installation position of the drainage riser can be adjusted by adjusting the special adjustable centering flange (which can correct the full-area installation error within 15mm) to ensure the smooth installation of the drainage riser.
