The installation method of this embodiment is the same as that of embodiment 4.
The modular same-floor drainage device for the building has the technical characteristic that the lowest position of a water outlet of a water seal mechanism is not lower than the lowest position of a water outlet of a vertical pipe connecting pipe, otherwise, smooth drainage cannot be realized.
In use, the modular multi-storey drainage apparatus for buildings according to embodiments 1-13 is used, in which the outlet of the toilet bowl is directly connected to the inlet 31 of the sewer pipe 30, and the sewage discharged from the toilet bowl directly flows into the vertical pipe connecting pipe 40 through the sewer pipe 30 and is discharged into the drainage vertical pipe. Part of the pipe body of the sewage pipe 30 is arranged in the water collecting tank 10, and part of the pipe body is embedded in the ground surface layer of the floor slab building structure, compared with the prior art, the thickness of the ground surface layer can be reduced by 30-50mm, namely, the minimum thickness of the ground surface layer of the toilet can be 50mm on the basis of the design of drainage of the lower drainage layer of the toilet and the drainage of the same layer, the spatial layout is optimized, and the building material consumption is reduced;
meanwhile, the waste water in the drainage outlets such as floor drains, bathtubs, wash basins, mop pools and the like in the toilet is directly gathered into the waste water drainage pipe 14, is drained into the water gathering tank 10 after passing through a water sealing mechanism, then flows to the water outlet 41 of the vertical pipe connecting piece 40, and is drained into the drainage vertical pipe from the water outlet. The water sealing mechanism can effectively block odor which is turned over and gushes in the vertical drainage pipe and the water collecting tank 1.
The waste water drain pipe 14 is directly connected with the water seal box in the water collecting box 10, so that a structure for concentrating water seal and deodorization is formed, a plurality of water seal designs in the prior art are replaced, and the problem of indoor odor return caused by failure of a certain water seal is avoided.
The design of the flanging 12 of the header 11 forms a lap joint mechanism of flat joint → downward turnover with the waterproof layer 51 of the toilet, so that the waterproof layer 51 can effectively cover the installation gap between the header and the floor slab installation hole without adopting concrete for filling; meanwhile, the end part of the waterproof layer 51 is positioned on the header top cover 11, and the height difference is formed between the waterproof layer and the waterproof layer on the ground, so that the ground accumulated water can flow onto the header top cover 11 in a guiding manner and is discharged into the header 10, and the accumulated water cannot flow backwards from the bonding seam between the waterproof layer 51 and the header top cover 11, thereby thoroughly solving the problem of accumulated water leakage at the position where a pipeline passes through a floor slab in the prior art.
It should be particularly noted that it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof, such as: the specific connecting position of the water seal tank and the header of the header and the shape of the water seal tank, the water seal tank adopts a water seal cylinder, a water seal bent pipe, a partition plate or other water seal components in the prior art, the position distribution of the water seal tank and a sewage pipe in the header, the shape of the sewage pipe, the position distribution of a water outlet on the header of the header and other technical characteristics are deformed. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
