Non-falling-plate same-floor drainage system for building toilet

Abstract

The invention provides a non-falling-plate same-floor drainage system for a building toilet. The system involves a transverse pipe drainage assembly arranged in a floor slab, and a drainage pipe assembly and a water seal assembly which communicate with the transverse pipe drainage assembly and positioned on two sides; the drainage pipe assembly communicates with an upper-layer main drainage pipeline and a closestool blow-off pipe; the water seal assembly comprises a floor drain arranged on the floor slab; the transverse pipe drainage assembly communicates with a lower-layer main drainage pipeline, collects waste water discharged from the drainage pipe assembly and the water seal assembly, and discharges the waste water through the lower-layer main drainage pipeline; and the interior of thetransverse pipe drainage assembly is of a flat cavity structure, and the bottom face of the cavity structure is obliquely arranged. According to the drainage system, the transverse pipe drainage assembly with the flat cavity structure is connected with the drainage pipe assembly and the water seal assembly, so that the occupied space is small, and the stable drainage effect 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 same-floor drainage system with non-falling boards for building toilets. 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...
