Introduction: The waterproof casing is divided into flexible waterproof casing and rigid waterproof casing. The rigid waterproof casing is seamless steel pipe with wing ring, which is installed in the wall to pass through the wall for general pipeline, which is conducive to the moisture-proof of the wall. According to the installation regulations of rigid waterproof casing and what should be paid attention to

Waterproof casing Share Flexible waterproof casing and Rigid waterproof casing In these two categories, the rigid waterproof casing is seamless steel pipe with wing ring, which is installed in the wall to pass through the wall, which is conducive to the moisture-proof of the wall. Do you know the installation regulations of rigid waterproof casing and the matters needing attention?
I. installation regulations of rigid waterproof casing
1. Carefully understand the engineering drawings and analyze how to make and install the casing of embedded parts before manufacturing and processing the casing.
2. Pay attention to the water supply and drainage casing in the manufacturing process. After installation, the branch pipe should be flush with the wall, beam and column.
3. The steel casing must be welded thoroughly with the water stop wing ring.
4. The gradient 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 flat roof should be expanded as much as possible.
5. Check whether there are gaps, sand holes and even wall thickness.
6. Before the pipeline is applied, the appearance, water injection and surface water flushing shall be inspected to see if there are cracks and sand holes one by one.
7. Check whether all sockets are timely, firm and dense.
8. The anti-seismic support shall be set according to the code for acceptance of engineering construction.
9. Determine the length of casing pipe according to the building plan, structural pipe surface drawing and building elevation, and then make it according to the water supply and drainage plane design drawing and detail drawing, and referring to the building atlas.
10. When making waterproof casing, the thickness of wing ring and casing shall meet the requirements. Both sides of wing ring of waterproof casing shall be welded thoroughly on both sides, and the welding shall be smooth, smooth, smooth, free of weld bead, bubble and crack. After welding, the welding penetration shall be cleaned up, and then the anticorrosive paint above shall be applied twice. During installation, both sides of the sleeve shall be clamped and fixed firmly on three sides of building steel bars, Do not tilt.
II. Common problems of rigid waterproof casing installation
1. Before the pipeline is applied, the appearance, water injection and surface water flushing shall be inspected to see if there is any gap and sand hole one by one.
2. When making waterproof casing, the thickness of wing ring and casing shall meet the requirements. Both sides of wing ring of waterproof casing shall be welded thoroughly on both sides, and the welding shall be smooth, smooth and smooth without weld bead.
3. Pay attention to the water supply and drainage casing during manufacturing. After installation, the branch pipe should be flush with the wall, beam and column.
4. The anti-seismic support shall be set according to the code for acceptance of engineering construction.
5. Make clear the length and length of the water supply and drainage pipe, and make the design according to the plan and the structure drawing of the building.
6. Carefully understand the engineering drawings and analyze how to make and install the embedded casing before manufacturing the casing.
7. 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 flat roof should be expanded as much as possible.
8. Check whether there are gaps, sand holes and even wall thickness.
9. The steel casing shall be fully welded with the periphery of the water stop wing ring.
10. Check whether all sockets are in place, firm and dense.
The above is about the rigid waterproof casing installation regulations and common problems, the content hope can help you, installation find professional personnel.
