Introduction: Toilet is one of the places where rigid waterproof casing is more commonly used. The rigid waterproof sleeve embedded in the concrete floor makes it convenient for the pipeline to pass through the concrete floor, and also provides convenience for the later maintenance of the pipeline.
Toilet waterproof sleeve Atlas

Toilets are rigid Waterproof casing One of the more commonly used places, embedded parts in the concrete floor Rigid waterproof casing It is convenient for the pipeline to pass through the concrete floor, and it also provides convenience for the maintenance of the pipeline in the later stage.
The sealing method of toilet waterproof sleeve atlas can refer to the relevant requirements of rigid waterproof sleeve in the industrial standard technical specification for rigid polyvinyl chloride pipe engineering of building drainage (CJJ / 29-98)
The construction of the road crossing the building shall meet the following requirements:
1. When the pipeline passes through the fixed fixed support point of the concrete floor, the support shall be carried out with the civil engineering after the pipeline installation, and the water stop ring with C20 fine 20mm and width no less than 30mm shall be selected.
2. When the pipe passes through the regenerating floor for non fixed support, the metal or plastic casing shall be modified. The nominal diameter of the casing is 10-20 mm larger than that of the crossing pipe, and the casing shall not be less than 50 mm above the ground.
When the sanitary ware drainage pipe connecting the horizontal branch pipe passes through the building, the sealing hole shall be set according to the engineering construction requirements of the pipeline crossing the building in this specification, and the water leakage prevention measures shall be adopted. In addition, the waterproof construction of the pavement of the fusion building should be done well, and the waterproof flanging of the inner wall of the pipeline should be done well. This kind of behavior can prevent the cost of lifting casing, and it is not easy to cause repair damage caused by positioning prohibition; for construction enterprises, the construction procedure is more complex, the cost is higher, and because the standards and regulations have been clearly stated, it is impossible to claim for the cost from the community owner, so there is a conflict mentality.
According to the above contents, it is suggested that rigid waterproof casing should be selected for the main standpipe when the toilet drainage pipe passes through the concrete floor, and the height width ratio of the casing is 50 mm higher than the decorative design road surface, while the connecting riser of sanitary ware and anti odor floor drain can adopt the method of embedding holes for secondary plugging when passing through the concrete floor.
