Anonymous users2024-01-23Hello, what is the ratio of ground backfill pottery coarse with dry mix sand bath paddle.
Of course it's important, or it's always pouring back the smell, which will make people annoyed. I know that the kitchen flue industry or Wanju Technology Residential Kitchen and Bathroom Exhaust Pressure Transformation System is more powerful, mainly due to technical improvement, which can ensure that there is no backflow of odor.
Please explain the specific situation, some cases cannot be simply filled, you need to open the ground to fill and tamp. Once!
According to the Ministry of Housing and Urban-Rural Development of the People's Republic of China issued the "Code for the Calculation of Building Surface of Construction Projects", regardless of whether the balcony is closed or open, concave balcony or picky balcony, it will be included in the construction area according to 1 2 of the balcony projection area.
The full area of a single-storey building should be calculated if it is above and above; If the height is insufficient, the area of 1 2 shall be calculated, and the balcony of the building shall be calculated according to the area of 1 2 of its horizontal projection.
Generally, it is 30--50mm, there is no hard rule, the concrete strength is high, and a small value can be taken; The strength of concrete is low, and the large value is taken.
