Same-floor drainage system without descending floor slab in bathroom

Abstract

The invention provides a same-floor drainage system without descending a floor slab in a bathroom. The same-floor drainage system is composed of a drainage vertical pipe, a sewage transverse branch pipe, a waste water transverse branch pipe, an integrated water seal, a floor drain, a wash basin pipeline and a ground floor slab, wherein the drainage vertical pipe penetrates through the ground floorslab; a water seal channel of the integrated water seal is arranged in the ground floor slab, and the outer wall of the transversely-closed bottom does not penetrate through the ground floor slab; the integrated water seal is provided with at least two openings above the ground floor slab, and the two openings communicate with each other and are converged and connected with the water seal channel; a waste water transverse branch pipe connector is connected with the floor drain and the wash basin pipeline; and the floor drain and the wash basin pipeline are correspondingly provided with a trapor a water seal device. The same-floor drainage system can solve the problems that floor descending is needed for same-floor drainage of a traditional building, and the traps are arranged below drainage points correspondingly and are prone to drying up and causing odor returning, and the effects that floor descending is not needed for same-floor drainage, no peculiar smell exists in the bathroom,and the pipelines are easy to overhaul are achieved.

Description

technical field [0001] The invention relates to a same-floor drainage system for building toilets, in particular to a same-floor drainage system for building toilets without falling boards. Background technique [0002] Bathrooms in traditional buildings are drained on the same floor. Due to the layout of drainage pipes, the building structure needs to be lowered to the floor. The height of the lowered slab is large (mostly about 300mm). They are all set separately, so that the water seals of infrequently used appliances are easy to dry up, the bathroom is prone to peculiar smell, and the maintenance and repair of pipelines is difficult. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a bathroom that drains water on the same floor of the building. It does not need to lower the floor of the building structure or reduce the height of the floor. It is a kind of non-falling board and same-floor d...
