Technical Field
The utility model relates to a toilet drainage system, in particular to a water return prevention drainage system of a different-layer drainage toilet easy to return water, and belongs to the technical field of constructional engineering.
Background
With the development of society, especially the progress of urban improvement in recent years, urban multi-storey and high-rise residential buildings brought by the vigorous growth of the house industry are increasing. Toilets are an indispensable part in residential buildings. At present, public drainage of domestic residential building toilets mainly adopts two forms of different-layer drainage and same-layer drainage, and the different-layer drainage form is the longest-application and most-extensive drainage system.
The principle is that the drainage branch pipe of the sanitary ware passes through the floor slab, and the drainage mode that the drainage branch pipe is connected under the top plate of the toilet of the lower resident is called different-layer drainage because the drainage pipeline and the sanitary ware are not on the same floor. The adoption of different-layer drainage has the main advantages that: the civil engineering construction is convenient, the cost is low, and the matched pipeline and sanitary ware market are mature.
For the drainage system of the form, many blockage of the transverse pipe at the bottom of the public vertical pipe or the turning part at the bottom of the vertical pipe caused by factors such as serious ageing of a long-aged residential pipeline, various sundries of a public main drainage pipeline, dumping of waste liquid in high-rise decoration construction, unreasonable pipeline design and the like occurs in application, the condition of water return of a toilet of a resident at the bottom layer is light, the whole toilet is polluted, and the whole set of house can be subjected to furniture bubbling, sewage passing and ozone smoking. Because the bathroom is built and can not be independently drained and reformed, no water backflow prevention reforming scheme for the bathroom is reasonably adopted at present, and the problems that the upper and lower layers of households and the property responsibilities and the blocking responsibilities of pipelines are unclear, the rights cannot be maintained and the like are solved, the water backflow problem of the bathroom is solved, the economy of the households is lost, the spirit is burdened, and the life is puzzled.

Description of the embodiments
As shown in fig. 1, the water return prevention drainage system of the different-layer drainage toilet easy to return water comprises an original floor drain pipe 2, an original floor drain pipe 3, an original basin drain pipe 4 and an original washing machine drain pipe 5 of the floor of the toilet, which are pre-buried in the floor, and a drainage pipeline of the lower-layer toilet of fig. 2, which is connected to a public main drainage vertical pipe 1. This range is the existing toilet drain, still being part of the retrofit system drain.
Before the pipeline is transformed, the existing decoration and water supply and drainage pipelines are removed from the bathroom of the layer, the state before the decoration is restored, the main drainage pipeline of the bathroom of the residential building is dredged, and the short-term non-blocking and non-return of water are ensured. The water supply, water resistance, other related decoration and the like of the bathroom are completed in good time in the implementation process of the whole scheme.
The area of this layer bathroom is divided into shower area, hanging toilet area, basin area, reservation washing machine area and passageway area, sets up the floor drain in shower area and passageway area, connects to floor former toilet drain pipe 2 through floor drain pipe 11, sets gradually check valve 8 and ball valve 7 on the pipeline, and the valve setting is in the maintenance groove 9. The wall-mounted toilet is arranged in a wall-mounted toilet area, is connected to the original floor toilet drain pipe 3 through a wall rear drain pipe 12, is sequentially provided with a check valve 8 and a ball valve 7, and is arranged in a decoration partition wall 10. The basin area is provided with a desk type basin, is connected to the original basin drain pipe 4 of the floor through a basin drain pipe 13, is provided with a check valve 8 and a ball valve 7 in sequence on the pipeline, and is provided with a space on the toilet completion surface below the basin. In addition, the floor original washing machine drain pipe 5 is used as a reserved area, and when the washing machine is arranged, the drain pipe and the valve are provided with the same basin area; the pipe plug can be used for temporary sealing when the washing machine is not arranged. After the pipeline and the valve are laid, the toilet determines the height of the cushion layer 6 and the thickness of the partition wall 10 according to the actual pipeline and the floor drain. In addition, a water blocking threshold 14 is arranged at the gate of the bathroom, so that the overflow of the ground water of the bathroom during water use at ordinary times is avoided.
After this scheme was implemented, when the trunk line bottom took place to block up, sewage in the riser can be through the drain pipe reflux at lower floor's bathroom figure 2 top, then through the former toilet drain pipe of floor 2 of this floor's bathroom, the former toilet drain pipe of floor 3, the former basin drain pipe of floor 4, the former washing machine drain pipe of floor 5, continue to reflux to each drain pipe's check valve 8, cause all valves to close, sewage is blocked in check valve 8 positions. When the resident on the floor uses the bathroom to drain, the water cannot be drained at the same time by finding out a plurality of pipelines, so that the problem that the main drainage pipeline is blocked is solved, and the property is required to be informed to dredge the main drainage pipeline in time. After the pipeline is dredged, the drainage of the toilet is recovered to be normal.
