Description

House drainage system

Technical Field

The utility model relates to the technical field of house drainage, in particular to a house drainage system.

Background

The purpose of the indoor drainage pipe is to discharge domestic sewage (such as toilet drainage) and domestic wastewater (other drainage) to the outside. Wherein the drainage riser is a main conduit that both drains water downwardly and vents air upwardly (suction and exhaust to control the pressure within the conduit). When the total floor number is higher, for example, more than 9 floors, the air suction and exhaust capacity of the drainage riser pipe cannot meet the ventilation requirement, which causes the internal pressure of the pipeline to be higher or lower, and therefore, an additional ventilation pipe needs to be added.

The existing sewage vertical pipe, waste water vertical pipe and ventilating vertical pipe are usually installed on site, namely, after a house is built, the vertical pipe unit is installed subsequently, so that the site construction period is increased, and time and labor are wasted. In addition, various existing drainage pipelines need to be embedded in building components such as walls, ceilings or floors, but if the pipelines leak, the building components are affected, so that the existing drainage pipelines are poor in installation sealing performance and heat preservation performance.

Detailed Description

The utility model will be described in further detail below with reference to the drawings and specific examples.

As shown in fig. 1 and 2: a house drainage system comprises a plurality of mould frames 1 which are connected up and down, wherein a vertical pipe joint 3 extending downwards is prefabricated at a preset position on a floor 2 of each mould frame, and when the upper mould frame and the lower mould frame are installed on site, a vertical pipe unit of the lower mould frame is fixedly connected with the vertical pipe joint 3 extending out of the upper mould frame.

The scheme has the following advantages: when the die carrier is installed on site, after the upper die carrier and the lower die carrier are assembled and installed, only the vertical pipe joint extending out of the floor in the upper die carrier is connected with the end part of the prefabricated vertical pipe unit in the lower die carrier, and the vertical pipes do not need to be installed on site, so that the installation period is greatly shortened, the installation speed is improved, and time and labor are saved.

In this embodiment, the riser unit includes a sewage riser 4, a waste water riser 5, and an aeration riser 6, and the number of riser joints 3 is set corresponding to the number of pipes of the riser unit. Wherein, the vertical sewage pipe 4 is mainly used for sewage discharge in a toilet, and the vertical waste water pipe 5 is mainly used for waste water discharge in the toilet and a kitchen, such as discharge of wash water, vegetable washing water and bath water; the ventilation vertical pipe 6 is mainly used for removing toxic and harmful gases and balancing air pressure. The sewage vertical pipe 4, the waste water vertical pipe 5 and the ventilation vertical pipe 6 are communicated, the sewage vertical pipe 4 and the waste water vertical pipe 5 are arranged on two sides of the ventilation vertical pipe 6, the ventilation vertical pipe 6 is respectively communicated with the sewage vertical pipe 4 and the waste water vertical pipe 5 through a combined ventilation pipe 61 which is obliquely arranged, and drainage can form air circulation through the ventilation vertical pipe 6.

In this embodiment, the lower ends of the sewage vertical pipe 4, the wastewater vertical pipe 5 and the ventilation vertical pipe 6 are all provided with vertical pipe joints 3, and the vertical pipe joints 3 extend out of the floor 2 and extend into the lower die carrier. And the upper end of each vertical pipe is connected with a vertical pipe joint 3 extending from the upper die frame. After each riser is inserted into the corresponding riser joint 3, the risers can be fixedly connected by threads, such as flange connection, or directly connected by colloid sealing. Thus, corrosion and water leakage can be prevented.

In this embodiment, branch pipes extend from the vertical sewage pipe 4 and the vertical wastewater pipe 5. For example: the branched sewage pipe 41 extending from the sewage vertical pipe 4 is connected with a corresponding toilet or squatting pan, wherein a communicating vessel is arranged between the branched sewage pipe 41 and waste water discharging equipment (such as the toilet), the communicating vessel is of a U-shaped structure, a water seal is arranged in the communicating vessel, the height of the water seal is 80mm, and the water seal can not only prevent air return, but also prevent water in the water seal from volatilizing naturally and quickly. In addition, when the toilets of two house types are arranged side by side and the toilet bowls of the two toilets are arranged back to back, one sewage vertical pipe 4 can be shared, and the two sides of the sewage vertical pipe 4 are connected with the sewage branch pipes 41 which are respectively connected with the communicating devices of the corresponding toilet bowls, so that the number of the vertical pipes is saved. Furthermore, the floor 2 of the toilet can be opened, and the sewage branch pipe 41 is buried in the floor 2 and the floor is blocked. The branch waste water pipes 51 extending from the waste water vertical pipe 5 are respectively connected to waste water discharge equipment of a toilet and a kitchen.

As shown in fig. 3: in this embodiment, the top of the topmost formwork is provided with a roof 7, the sewage riser 4, the wastewater riser 5 and the ventilation riser 6 are connected to a main ventilation pipe 8, and the main ventilation pipe 8 penetrates through the roof 7 to be communicated with the outside atmosphere, so that gas is exhausted to the atmosphere, and the gas pressure can be balanced.

As shown in fig. 4: in this embodiment, when each corresponding pipeline is prefabricated with a building component corresponding to a house, an insulating layer 9 is arranged between the pipeline and the building component, and the opening side of the building component where the pipeline extends in and out is coated with an anti-mildew sealant 10 or a weather-resistant sealant. For example: when the corresponding riser pipe passes through the ceiling or the floor, the mildew-proof sealant 10 is applied to the contact side of the riser pipe and the ceiling or the floor to prevent the floor or the ceiling from being affected by water leakage of the riser pipe. The ceiling/floor can be isolated from the pipe by providing an insulation layer 9, preferably of foamed polyurethane material, between the ceiling/floor and the pipe so that the ceiling/floor is not affected by cold or hot water in the pipe. Similarly, when the branch waste pipe 51 or the branch sewage pipe 41 passes through a wall or a floor, the heat-insulating layer 9 is arranged and the mildewproof sealant 10 is coated as before, so that the waterproof and heat-insulating effects are achieved.

In conclusion, on one hand, the stand pipe units and the stand pipe joints are prefabricated in the die carrier in advance, so that the stand pipes do not need to be installed on site, the installation period is greatly shortened, the installation speed is improved, and time and labor are saved; on the other hand, the heat retaining property and the waterproofness are good.
