Flat pipe preposition floor drain type non-descending board same floor drainage system

Abstract

The invention discloses a flat pipe preposition floor drain type non-descending board same floor drainage system. A bathroom composed of a drainage toilet, a shower room, a washbasin and a body cleaner is taken as a research object, a drainage pipeline is laid by dirty and waste diversion, and a back drainage toilet is drained into a vertical pipe through a sewage pipeline, the body cleaner, the washbasin, the shower room and other places floor drain drainage is drained into the vertical pipe through a waste water pipeline, and a waste water transverse pipe and the vertical pipe are connected in a flat shape rotational flow three-way mode. Preposition type floor drains are correspondingly installed in the shower room, and on one side of the washbasin in the spare ground; and in terms of a pipeline section form and a laying method, the sewage pipeline adopts the traditional round pipe hidden laying along a wall, the waste water pipeline adopts a flat shape pipeline buried hidden laying method, the height of a whole waste water pipeline to the greatest extent is reduced under the premise of meeting the drainage capacity is satisfied, and thus the flat pipe preposition floor drain type non-descending board same floor drainage system is one of the technical schemes with the minimum height in a present buried hidden laying same floor drainage system.

Description

technical field [0001] The invention relates to the technical field of same-floor drainage for building toilets, in particular to a flat-pipe pre-floor drain-type non-falling plate same-floor drainage system. Background technique [0002] At present, the existing same-level drainage system is divided into three types: full-falling slab, partial falling slab and non-falling slab same-floor drainage system. The thickness of the same-floor drainage system with full-falling slab and partial falling slab is 250-400mm. The main problem is that the thickness of the falling slab is too large 1. The use of bonding pipes leads to easy water accumulation in the caisson, and the project cost is uneconomical; the thickness of the descending plate of the drainage system on the same floor without falling slabs is 150-250mm. The main problem is that the pipe fittings for the sewage riser are embedded in the floor, and it is necessary to open more holes. Large, unable to effectively block, r...

Problems solved by technology

[0003] In view of the above existing problems, the present invention aims to provide a flat tube pre-floor drain type non-falling board same-floor drainage system, including the bathroom main body and the ground, and solves the need to open when the floor is pre-embedded by setting the pre-type floor drain and flat tube components. The problem of large holes and fire prevention between the upper and lower floors also greatly reduces the height of the descending plate
