The introduction of airtight waterproof casing
Generally when doing the pool to use casing, it is the channel to sink pipe. But ordinary casing is difficult to seal, thus there will be leakage between casing and pipeline, between casing and the wall is also easy to leak. Only use waterproof casing to solve the leaking between the casing and wall, can't solve the problem that casing and pipeline sealing, flexible waterproof casing can solve the two problems.

The classification of airtight waterproof casing
Casing can be divided into: ordinary casing - than to use the pipeline crude 2-4 cm, fixed inside a wall or board, pipe it through. Flexible casing - is between casing and pipe with flexible material to block the sealing effect. Rigidity - is casing pipe and the pipe plugging with rigid material to achieve sealing effect. Waterproof casing, casing is used by the environment is to prevent liquid leakage or leakage into the places (such as tank, septic tanks, basement, etc.), is of no less than 1 lap in the outside casing wall waterproof wing, when such casing casting within the walls as a whole, will not appear crack and leakage by expansion factor.

Airtight waterproof casing matters needing attention
1 the flexible waterproof casing generally applicable for pipe through the wall of the vibration or tight waterproof requirement of structures.
Part 2, casing processing is completed, both in its outer wall paint primer again (primer ZhangDan or cold priming oil). The outer corrosion is determined by the design.
3, casing wall in the wall, in case of the concrete wall should be switched to the concrete wall, the scope of concreting shall be colorful ring (D6) 200 mm in diameter, and must be poured casing solid and walls.
4, wear in the concrete wall thickness shall be not less than 300 mm otherwise should be made on both sides of the side wall thickening or upset. Increasing the diameter of the part minimum colorful ring diameter of 200 mm (D6).
5, the material weight of the casing is calculated on wall thickness value is 300 mm L, such as wall thickness is greater than 300 mm should be calculated separately.
