In the construction and interior decoration stage, outdoor and indoor drainage occupy a very important position. The setting of the drainage pipe slope will directly affect the fluency of the outdoor and indoor drainage of the building, so it will be directly related to the daily use of the residents. There is a very strict acceptance and setup process for the setting of pipe gradients. The following small series for everyone to introduce underground toilet drainage slope requirements and underground toilet drainage plug how to do.
Underground bathroom drainage slope requirements
According to Article 4.2.10 of the Code for Design of Outdoor Drainage (GB50014-2006), the minimum diameter of the drainage pipe and the corresponding minimum design gradient are specified as follows: minimum diameter of the sewage pipe d300mm / corresponding minimum design gradient plastic pipe 0.002 , Others 0.003. Rainwater pipe minimum diameter d300mm / corresponding minimum design grade plastic pipe 0.002, other pipes 0.003. Slopes of outdoor drainage pipes In general, there is no specific specification for the setting of the maximum slope, because the setting of the slope of the outdoor drainage pipe also has many influencing factors, such as the material of the pipe, the size of the pipe diameter, and the size of the flow rate. Aspects affect the setting of the slope of the drainage pipe. The setting of the slope of outdoor drainage pipes and the installation and acceptance procedures for pipelines are particularly rigorous. It is necessary to carry out detailed inspection of some projects. The project manager, construction agency, and supervision agency jointly participate in the quality inspection of inspection batches. If there are subcontracting items, they also need to be divided. The project manager of the package unit signed and accepted and performed acceptance and signature on all aspects of the slope of the drainage pipe, irrigation before the pipeline was laid, water flow, trench treatment, and the strength of the well floor.
The slope of the indoor drainage pipe is different from that of the outdoor drainage pipe, and the design of the interior is relatively complicated. Therefore, it is generally not calculated separately in sub-areas and sub-areas, but a specific value is used to directly determine the drainage pipe. slope. The slope of such a drain pipe is generally stipulated in relevant documents such as the acceptance standard. When the interior decoration is performed, the owner and the design and construction personnel must understand the relevant acceptance specifications, determine the standard value of the relevant drainage pipe slope, and the minimum The slope value and the standard spacing between fulcrums can better complete the smooth design of indoor drainage. The slope of the drainage pipe is related to the material of the drainage pipe used. In general, the cast iron pipe has a larger friction coefficient, so when designing the slope of the drainage pipe, the slope design should be larger than the plastic drainage pipe. Conventionally, the slope of the indoor drainage pipe is controlled between 25% and 30%, and the specific value still needs to refer to the corresponding specification. For the toilet slope of the toilet, generally set at about 2% is appropriate, set the slope as little as possible, if the slope is too high, may cause inconvenience to the use of other related parts of the bathroom.
How to do underground toilet drainage
1, sewer dredge agent: is the best product on the market, this product is good for hair, oily, paper towels and other blocking effect. It is used to clear the clogged basins, washbasins, floor drains, toilets, etc. It does not damage the sewer pipe, including the PVC pipe. Use it according to the above instructions.
2, you can use the care of home care, the sewer mouth, and then put a half pool of water, under the influence of suction and pressure, the toilet can also pass.
3, to the market to buy a special toilet through the pito child, aimed at the mouth of the sewer, hard to pull, in the role of suction, the toilet can also pass.
Editor's summary: The underground bathroom drainage slope requirements and how to do the underground toilet drainage are introduced here, and I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
