[waterproof sleeve type introduction] 
Commonly used waterproof casing is divided into rigid and flexible two. Care should be taken when selecting the type: The waterproof casing is manufactured according to the S312, 02S404 standard atlas developed by the Building Science Research Institute. Rigid waterproof casing is suitable for installation of drinking water pool waterproof casing. After asbestos cement is filled, it is necessary to ensure that all contact surfaces in the seam are free of rust, paint, dirt, and are clean and dry. It is generally applicable to structures where vibrations or strict waterproofing requirements are applied to pipelines passing through the wall; in case of non-concrete walls, walls that pass through walls should be replaced with concrete walls, and the casing must be solidified in the wall; Pipes are applied to construction, chemical, steel, tap water, sewage treatment and other units.
The flexible waterproof casing is a hardware fitting that is suitable for pipelines that pass through the wall and is subject to vibration or strict waterproof requirements. The general production enterprises are manufactured according to the S312, 02S404 standard atlas developed by the Building Science Research Institute. Flexible waterproof casing through the walls of the wall, in case of non-concrete should be replaced with concrete walls, the casing must be solidified in a wall; flexible waterproof casing is widely used in construction, chemical, steel, tap water, sewage treatment, etc. unit.
Rigid waterproof casing is a steel pipe with a wing ring (an annular sleeve made of steel plate on a steel pipe) installed in a wall (mostly a concrete wall). It is used for general pipe wall penetration to facilitate the waterproof of the wall, and the flexible waterproof casing is not only The outer wing ring, the inner ring, and the like, flanged wire, are sold in kits, and can also be processed on their own, used for pipelines that require shock absorption, such as when a pipe connected to a water pump passes through a wall.
[waterproof sleeve installation method]
I. "Installation with civil construction"
- The pipeline should be installed along with the civil works when it is used to penetrate the shear wall foundations, cross beams, and special-shaped columns of concrete structures. The reason is that after the hole is reserved, the secondary pouring between the casing and the concrete is not easy to handle; some cannot be handled, such as installing a rigid waterproof casing on the concrete base shear wall of the basement.
Second, "install before installing the pipeline" 
- When the pipeline is passing through a concrete slab or an ordinary brick wall, holes are generally reserved on the concrete floor slab. Ordinary brick walls can be chiseled over the wall. Floors, before the safety pipe, dropped the line, install the casing. On the brick wall, draw a line, plant a stand, find a good slope, and install a casing.
First of all, before installing and using the waterproof casing pipe, it should first observe the appearance, irrigation and flushing of the outer wall to check whether there are cracks or blisters.
Next, check all fittings for cracks, presence of blisters, and whether the wall thickness is uniform.
Again, check that all sockets are in place, strong, and dense.
Finally, when the waterproof casing is installed, the slope of the pipeline should be uniform and there should be no inverted slope. The slope of the pipeline at the exit of the roof should be increased appropriately.
Xiaobian conclusion: The above introduced the waterproof casing installation method , I believe we have a more comprehensive understanding of the waterproof casing installation. For more relevant knowledge, please continue to pay attention to this website information platform.
