A non-falling slab drainage system for building jump floors

Abstract

The invention provides a non-falling slab drainage system for a building jump, including a first-floor drainage system and a second-floor drainage system. The first-floor drainage system includes a first-floor drainage pipe assembly. The lower part is respectively connected with the upper general drainage pipe, the first floor toilet sewage pipe and the first lower general drainage pipe; the secondary drainage system includes horizontal pipe drainage components and secondary drainage pipes connected to the horizontal pipe drainage components and located on both sides components and water seal components, the upper part, side part and lower part of the secondary drainage pipe assembly are connected with the first lower general drainage pipe, the secondary toilet sewage pipe and the horizontal pipe drainage assembly respectively, and the horizontal pipe drainage assembly is connected with the second The main drainage pipes in the lower layer are connected; the interior of the horizontal pipe drainage assembly is a flat cavity structure, and the bottom surface of the cavity structure is inclined. Therefore, by adopting the horizontal pipe drainage assembly with a flat cavity structure, the occupied space is small, and drainage can be realized without lowering the floor.

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
