Modularization same-layer drainage device for high-rises and mounting method thereof

Abstract

The invention provides a modularization same-layer drainage device for high-rises and a mounting method thereof. The drainage device comprises a water accumulating box, a vertical tube connecting pipe which penetrates in the water accumulating box, a lower air pipe which penetrate the bottom wall of the water accumulating box and is not higher than the top of a top cover of the water accumulating box, an upper air pipe which is installed on the top cover of the water accumulating box and is communicated with the inner part of the water accumulating box; and a waste water discharge inlet which is installed in the top cover of the water accumulating box; a gas passageway is installed between the upper air pipe and the lower air pipe; a vertical tube connecting pipe is provided with a water outlet which is positioned inside the water accumulating box; the waste water drainage inlet and a water outlet are communicated; the top of the lower air pipe is not lower than the highest point of the water outlet; a transversely arranged sewage pipe is embedded in an upper part of the water accumulating box; the axial distance between a water closet connecting port of the sewage pipe and the vertical tube connecting pipe is not larger than 500mm. The modularization same-layer drainage device for high-rises of the invention has a simple structure, scientific design and reliable performance and is convenient to use; the device has excellent seepage-proofing performance; stink proofing is realized by concentrated water sealing; the ground layer thickness is small and material is saved.

Description

technical field

[0001] The invention relates to the technical field of building water supply and drainage devices, in particular to a modular same-floor drainage device for high-rise buildings and an installation method thereof. Background technique

[0002] The drainage system of existing high-rise buildings mostly adopts a double riser drainage system. Usually, the riser connecting pipe and the ventilation pipe connecting pipe are pre-buried in the part where the drainage riser and the ventilation pipe pass through the floor, so as to connect the drainage riser and the lower floor. Ventilation pipe, at the same time, the connecting piece is used to connect the riser connecting pipe and the ventilating pipe connecting pipe; however, in the specific application process, the following disadvantages appear: 1) In order to avoid leakage, the waterproof layer is usually turned up along the pipe and a water blocking platform is installed , making the indoor floor layout appear me...
