Introduction: The water pipe is easy to crack, and it will affect the domestic water supply of the residents. Therefore, it is necessary to install waterproof sleeve in the area where damage is likely to occur. Do you know how to choose a suitable waterproof casing? Let's follow Xiaobian to have a look

The water pipe is easy to crack, and it will affect the domestic water supply of the residents. Therefore, it is necessary to install the water pipe in the vulnerable area Waterproof casing Do you know how to choose a suitable waterproof casing? Let's follow Xiaobian to have a look.
Manufacturing and installation of waterproof casing:
1. Carefully understand the drawings and analyze how to make and install the embedded casing before manufacturing the casing.
2. Determine the length of casing according to the building plan, structural pipe surface and building elevation. And then make the detailed drawing according to the standard of water supply and drainage.
3. Pay attention to the manufacturing of water supply and drainage casing. After installation, the branch pipe should be level with the completed surface of wall, beam and column.
4. The steel casing shall be fully welded near the water stop wing ring.
5. After the installation of electrical sleeve, both sides of the branch pipe should extend 5cm-10cm out of the wall, beam and column.
Making Flexible waterproof casing The thickness of wing ring and casing shall meet the requirements. Both sides of wing ring of waterproof casing shall be fully welded on both sides, and the welding seam shall be full, smooth, smooth, free of slag inclusion, bubble and crack. After welding, clean up the welding penetration, and then brush more than two times of anti-corrosion paint. During installation, the two sides of the casing shall be clamped and fixed firmly by more than three sides of reinforcement, and shall not be inclined.
Installation of waterproof sleeve:
1. Before the pipeline is applied, the appearance, irrigation and surface water flushing shall be inspected to see if there is any gap and sand hole one by one.
2. Check whether there are gaps, sand holes and even wall thickness.
3. Check whether all sockets are in place, firm and dense.
4. The inclination of the pipeline should be even and there should be no back slope. The inclination of the pipeline at the entrance and exit of the roof should be expanded as much as possible.
5. Supports and hangers shall be set according to the construction acceptance specification for pipeline installation. For rainwater pipe installation, inner drainage waterproof sleeve and downpipe installation, the pressure bearing capacity of pipe fittings must be considered and selected according to the design requirements.
6. The drainage pipes in high-rise buildings can be made of rare-earth cast iron, and the pressure of pipe fittings can be more than 0.8MPa. The length of pipe fittings can be based on the height of the floor. Only one pipe is needed for each floor, and a cement mortar mouth is twisted.
7. Cast iron drainage pipe is used for installation, and the installation method is the same as that of the drainage pipe in the room.
8. The connecting pipe of rainwater funnel shall be fixed on the roof bearing structure. The joint between the edge of rainwater funnel and the roof shall be tight without leakage.
9. After the installation of waterproof casing rainwater pipe, irrigation test shall be conducted, and the height width ratio must reach the rainwater funnel at the upper end of each riser.
10. During installation, the two sides of the casing shall be clamped and fixed firmly with more than three reinforcement bars, and shall not be inclined.
The maintenance of flexible waterproof sleeve is needed when the pipeline passes through the wall: analyze the damage that the pipeline is easy to suffer when passing through the wall. Generally, the pipeline is not stable, accompanied by the internal medium or the surrounding environment. It will vibrate in a small range. Once the protective measures are not taken, the fluctuation will be hindered by the wall, which will cause damage to the pipeline.
When the pipeline encounters the earthquake or the surrounding explosion shock wave, it will shake strongly. Similarly, because the wall is firmly locked, the internal energy can not be changed, resulting in the pipeline damage. There are many situations like that, and we do not give examples one by one. There is another example that is closer to our daily life. That is, the flexible waterproof casing used in the bathroom can prevent the corrosion of water from the outside to the pipeline.
