This product, like the pre-buried sleeve, is pre-positioned above the formwork before the cast-in-place construction in the early stage of civil engineering construction, and the concrete embeds it in the floor slab. Its main purpose is to drain the accumulated water in the caisson in the same-floor drainage. After the riser is inserted, it ingeniously forms a water seal with the pre-buried floor drain, playing the role of inhibiting bacteria and preventing odor. It is mainly composed of the main body of the pipe fitting, the inner eccentric ring, the outer eccentric ring (including the diversion rib), the waterproof wing ring, and the staggered positioning lugs. In the later stage, it is connected by the method of connecting the lower flange rubber ring and the upper clamp. The lower flange is a through-type connection, and can also adjust the insertion depth of the riser up and down, which is convenient for maintenance and disassembly. The waterproof wing ring is used to prevent wat
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 adjust the installation position of the drainage riser, so as to ensure the smooth installation of the drainage riser.
