Non-falling-plate drainage system for building skip floor

Abstract

The invention discloses a non-falling-plate drainage system for building skip floor. The system involves a first-layer drainage system body and a second-layer drainage system body; the first-layer drainage system body comprises a first-layer drainage pipe assembly, and the upper portion, the side portion and the lower portion of the first-layer drainage pipe assembly communicate with an upper-layer main drainage pipeline, a first-layer closestool blow-off pipe and a first lower-layer main drainage pipeline; the second-layer drainage system body comprises a transverse pipe drainage assembly, and a second-layer drainage pipe assembly and a water seal assembly which communicate with the transverse pipe drainage assembly and located on two sides; and the upper portion, the side portion and thelower portion of the second-layer drainage pipe assembly communicate with the first lower-layer main drainage pipeline, the second-layer closestool blow-off pipe and the transverse pipe drainage assembly, the transverse pipe drainage assembly communicates with a second lower-layer main drainage pipeline, the interior of the transverse pipe drainage assembly is of a flat cavity structure, and thebottom face of the cavity structure is obliquely arranged. According to the system, by adopting the transverse pipe drainage assembly with the flat cavity structure, the occupied space is small, and the drainage can be achieved without falling a floor slab layer.

Description

technical field [0001] The invention relates to the field of building drainage systems, in particular to a non-falling board drainage system for building jumps. Background technique [0002] The development process of building drainage system roughly has the following two stages: [0003] refer to figure 1 , figure 1 The building drainage system shown in is the first-generation building drainage system, including a first connecting pipe 101 connected to the floor drain, a second connecting pipe 201 connected to the washstand, and a third connecting pipe 301 connected to the toilet. The connecting pipe 101 , the second connecting pipe 201 and the third connecting pipe 301 are all disposed through the floor 401 . The waste water in the first connecting pipe 101 , the waste water in the second connecting pipe 201 and the sewage in the third connecting pipe 301 pass into the confluence riser 601 through the main pipe 501 and are discharged. Since the first connecting pipe 10...

Problems solved by technology

Although the second-generation building drainage system solves the problem that the leakage of the first-generation building drainage system affects the lower-level residents, when using the second-generation building drainage system, the height of the floor 401 needs to be lowered at the pipe installation site, which still encroaches on the lower-level residents. space, and water accumulation is prone to occur in the cushion layer, making pipeline maintenance difficult and inconvenient for construction
