Introduction: When processing and embedding the embedded pipe, pay attention to the consistency of the pipe diameter and the embedded position with the design requirements. After the embedded pipe is embedded in time, the steel bar is used to weld the pipe and wall steel bar firmly, so as to avoid the displacement during the concrete pouring and tamping, which will affect the subsequent connecting pipe construction. Since the embedded pipe is flush with the wall, after the formwork is removed, it is necessary to

When processing and embedding the embedded pipe, pay attention to the consistency of the pipe diameter and the embedded position with the design requirements. After the embedded pipe is embedded in time, the steel bar is used to weld the pipe and wall steel bar firmly, so as to avoid the displacement during the concrete pouring and tamping, which will affect the subsequent connecting pipe construction. Since the embedded pipe is flush with the wall, the concrete outside the wing ring needs to be cleaned up in time after the formwork is removed, so that all the wing rings can be completely exposed.
When the wing ring is painted on the wall, the anti-corrosion measures should be taken in time.
The method of embedded pipe out of the wall is the old one. Due to the great contradiction with the concrete construction, the embedded quality is not high, so now most of them are embedded in the way mentioned above.
At 02s404 Waterproof casing In the drawing set, DN is the diameter and model of the waterproof casing, and is the outer diameter of the waterproof casing that can pass through, with the unit of mm. D2 is the outer diameter of the waterproof casing, which can be ignored. D3 is the inner diameter of the flange gland of the waterproof sleeve, which is also equivalent to the inner diameter of the retaining ring of the waterproof sleeve, which is the outer diameter of the * large pipe that the sleeve can pass through. Therefore, the applicable waterproof casing model can be selected by referring to D1 and D3.
For example, if the outer diameter of the drainage pipe is 108mm, the applicable waterproof casing model should be DN 100. For the drain pipe with outer diameter of 133mm, the applicable waterproof casing model should be DN 125. For the drain pipe with outer diameter of 159mm, the applicable waterproof casing model should be DN 150. For the drainage pipe with outer diameter of 219mm, the applicable waterproof casing model should be DN200
Naturally, there are also unique conditions. For example, the outer diameter of the drainage pipe is 11 mm, and the inner diameter of the flat washer of the DN 100 waterproof sleeve is 114 mm. This pipe can not go through. If the DN200 casing is used, the pipe is too thin to play a waterproof role. What should be done? At this moment, if you tell us the outer diameter of the pipe to be penetrated, we can moderately increase the inner diameter of the DN 100 casing, for example, to 120 mm, so that the pipe can easily pass through, and then adjust the sealing ring.
