Waterproof casing Installation in basement wall board, cast-in-place slab, toilet floor slab, pool concrete slab, and forget to embed them during construction. How to open a hole and how to waterproof? Technical personnel here to explain to you, the key to solve the problem is: 1, how to punch? 2. How to fix and waterproof between waterproof casing and concrete? 3. How to deal with the surface waterproof after the installation of waterproof casing?
1. Drill holes with concrete drilling machine (concrete coring machine), and the hole diameter is 40mm larger than the pipe diameter. When drilling concrete, pay attention to the damage to the nearby concrete;
2. Try to fix the embedded waterproof sleeve with the reinforcement in the concrete slab by electric welding;
3. Fixation Rigid waterproof casing Apply 10 mm wide and 10 mm thick SM glue (water swelling sealant) on the outer wall of the front winding casing;
4. The joint between the rigid waterproof casing and the concrete shall be closed with wood plate or other methods, and a grouting hole shall be reserved for pouring in the self leveling cement mortar without retraction. The concrete surface shall be wetted and cleaned before pouring cement. If the general mixed mortar is poured into, it should be poured in layers at least twice. Each time of pouring should be carried out after the last final setting of mortar, and the mortar should be tamped and inserted tightly each time.
2) apply a layer of polyurethane waterproof coating to the two sides of the casing pipe, which is 50 mm thick. The width of architectural coating on concrete is greater than 100 mm. If the waterproof sleeve protrudes from the wall, the width of coating on the casing is about 50 mm; if the casing is flat with the concrete surface, the coating shall be applied to the inner cavity of the casing by 20 ~ 50 mm.
6. SM glue can be replaced by 50 mm wide × 2 mm thick butyl sealing tape, and the adhesive tape shall be around the pipe wall. If the concrete is thick, waterproof glue or tape can be applied twice;
7. The waterproof sleeve can not be used as waterproof wing ring, but it must be fixed firmly;
  8、 Flexible waterproof casing The waterproof between the pipe and the pipe should not be ignored.
The modern new integrated heat-resistant rigid waterproof casing has a water locking ring fixed outside the steel sleeve. A circular filling cavity is formed between the inner cavity of the steel sleeve and the surface of the working pipe. Two steel sleeves are respectively fixed in the circular filling cavity to produce a waterproof protection ring. The jugular vein of the waterproof spacer is welded and fixed on the steam insulation pipe, and the inner circumference of the waterproof spacer ring is welded On the surface of the jugular vein, the circular filling chamber is filled with thermal insulation material.
