Double-layered water and tidal drainage device of sectional combined floor drain and construction method

Abstract

The invention discloses a double-layered water and tidal drainage device of a sectional combined floor drain. The double-layered water and tidal drainage device comprises an adjustable double water drainage casing pipe which comprises an inner pipe and an outer pipe. The inner pipe and the outer pipe are adhered through a solvent adhesive for a plastic pipeline system. A plurality of first permeable holes are formed in the inner pipe, a plurality of second permeable holes are formed in the outer pipe, the second permeable holes are formed close to the upper end of the outer pipe, and first reinforced concrete structures are poured on two sides of the outer pipe. The adjustable double water drainage casing pipe is pre-buried in a position of a main drain pipe or the floor drain. By engineering means of joint action of the water drainage casing pipe, a plastic water drainage plate, geotechnical cloth and the like, sewage accumulated below a finish coat of a toilet is drained thoroughly,so that environment-friendly, healthy, attractive and safe purposes are achieved.

Description

technical field [0001] The invention relates to the technical field of indoor drainage, in particular to a segmented combined floor drain double-deck drainage device and a construction method. Background technique [0002] There are two main types of secondary drainage in existing bathrooms: the first is to install a secondary drainage floor drain, and a prefabricated reinforced concrete overhead layer is installed on the sinking layer; the second is to install a secondary drainage floor drain, and the sinking layer is made of ceramsite or waste slag backfill. The above method is mainly used in the drainage toilets on the same floor, and no attention is paid to the drainage toilets on the interlayer. The two methods have their own advantages and disadvantages, and it is difficult to achieve a perfect unity of appearance and function; at the same time, if the sunken toilet is not handled properly, problems will be found later Reprocessing is more cumbersome than that of the ...

Problems solved by technology

The above method is mainly used in the drainage toilets on the same floor, and no attention is paid to the drainage toilets on the interlayer. The two methods have their own advantages and disadvantages, and it is difficult to achieve a perfect unity of appearance and function; at the same time, if the sunken toilet is not handled properly, problems will be found later Reprocessing is more cumbersome than that of the compartment type toilet. Therefore, we propose a segmented combined floor drain double-layer drainage and moisture removal device and construction method to solve the above problems.
