Waterproof casing

Waterproof casing is also called through wall casing. Flexible waterproof casing is generally applicable to structures with vibration or strict waterproof requirements where the pipeline passes through the wall. After the casing part is processed, the outer wall shall be painted with primer (including camphor Dan or cold primer oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The flexible water-proof casing is mainly used in places with high requirements such as civil air defense wall and pool, while the rigid waterproof casing is generally used in the basement where the pipeline needs to pass through.

What are the benefits of using waterproof casing?
1. Protect the pipeline from damage
1) In order to prevent the pipeline from being damaged by overload, the pipeline should be protected from overload;
2) Plastic pipes should be protected in real time when passing through the wall;
3) When the pipeline passes through the foundation wall, it is generally concrete wall, and waterproof casing should be installed to protect the pipeline;
4) When the pipeline passes through three joints (expansion joint, settlement joint and anti vibration joint), in order to ensure that the pipeline will not be damaged by the three joints, waterproof casing should be installed to protect the sleeve;
5) When the geothermal coil passes through the expansion joint set in the middle of the room, waterproof casing should also be installed to protect the heat pipe.
2. Convenient installation and maintenance of pipes
1) Casing and temporary pipe support are used to fix the pipeline;
2) The setting of casing can avoid the damage to indoor decoration due to the replacement of pipes;
3) When the casing pipe is installed over the wall, the damage to the pipe shall be avoided;

Third, install casing in the room with water to prevent water seepage, flowing and flowing
1) After the completion of the project, due to improper reasons during the decoration of the user, the tap water flows through the casing and flows to the lower layer;
2) After the user enters, the tap water flows through the casing and flows to the lower layer due to unexpected reasons;
The causes are: 1. The casing is high and low; 2. The height is enough, but the casing seal is not tight.
Therefore, there are strict regulations on the height of the casing: in the room with water, the height of the casing should be 50 mm higher than the living ground; the height of the plastic water supply pipe should be more than 100 mm higher than the survival ground. And sealed tightly with ointment.

Fourth, prevent cross contamination
1) When the water supply pipe passes through the water supply pipe, it must be restricted by the water supply pipe;
2) Due to the limitation of indoor water supply pipeline, according to the requirement that the net moment of the septic tank is less than the specification requirements, the casing pipe must be set outside the water supply pipe, and the length should be made according to the design requirements.

Brief introduction of waterproof casing:
Waterproof casing is also called through wall casing. Flexible waterproof casing is generally applicable to structures with vibration or strict waterproof requirements where the pipeline passes through the wall. After the casing part is processed, the outer wall shall be painted with primer (including camphor Dan or cold primer oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The flexible water-proof casing is mainly used in places with high requirements such as civil air defense wall and pool, while the rigid waterproof casing is generally used in the basement where the pipeline needs to pass through.
Flexible waterproof sleeve is a kind of metal pipe fitting which is suitable for the structure with vibration or strict waterproof requirements where the pipe passes through the wall. The general manufacturers are manufactured according to S312 and 02s404 standard atlas developed and designed by the Architectural Science Research Institute. If the wall where the flexible waterproof casing passes through the wall, the concrete wall should be used if it is not concrete, and the casing must be solidified in the wall at one time; the flexible waterproof casing is widely used in construction, chemical industry, steel, tap water, sewage treatment and other units.  
Rigid waterproof casing is steel pipe with flange ring (steel plate is made of annular sleeve on steel pipe), which is installed in the wall (mostly concrete wall). It is used for general pipeline through the wall, which is conducive to the waterproof of the wall. Besides the external wing ring, the flexible waterproof sleeve also has baffle ring inside. It can be sold in sets or processed by itself. It can be used for pipeline with shock absorption, such as connecting with water pump When the pipe passes through the wall.
Both flexible and rigid water-proof sleeves are hardware fittings for pipes to pass through the walls of buildings subject to vibration or strict waterproof requirements. They are commonly used in construction, chemical industry, steel, tap water, sewage treatment and other units.
The most intuitive difference between the rigid waterproof casing and the flexible waterproof casing is that the appearance is different. The flexible waterproof casing has a rubber water stop ring inside, so as to prevent water leakage when used in the pool wall. Their installation length is different. The standard length of flexible casing is 300 mm, while that of rigid casing is 200 mm. However, they have one thing in common, which can be extended or shortened arbitrarily.

Installation method of waterproof casing:
1、 Installation together with civil construction
——When the pipeline passes through the shear wall foundation, beam and special-shaped column of concrete structure, it shall be installed together with the civil engineering. The reason is that the secondary pouring between the casing and the concrete is not easy to handle after the holes are reserved; some cannot be handled, such as installing rigid waterproof casing on the concrete shear wall of basement foundation.
2、 Installation before piping installation
——When the pipeline passes through the concrete floor and common brick wall, holes are generally reserved on the concrete floor, and the common brick wall can be drilled through the wall hole. At the floor, before installing the pipeline, drop the line and install the casing. On the brick wall, draw lines, plant supports, find the slope, and install the casing.
Construction of waterproof casing pipe:
1. The main pipe of waterproof casing adopts ductile cast iron pipe, rubber ring socket joint, d325 × 8 welded steel pipe is used for bridge pipe, d219 × 6 welded steel pipe is used for embedded branch pipe along the road.
2. Before the construction, the pipe fittings and valves shall be tested, and the pressure level shall not be lower than 1.5 times of the working pressure of the pipeline. After the materials enter the site and before the pipe laying, the pipes and accessories shall be inspected, including written certificate and physical inspection.
3. It is strictly forbidden to throw or collide violently in the process of transportation, loading and unloading and stacking. The laying of pipes shall be carried out only after the trench inspection is qualified. Before laying the pipes, the appearance of pipes and fittings shall be re inspected, and the pipes and fittings with problems shall not be used.
4. When the waterproof casing pipe is lifted and put into the groove, the reliable soft belt sling shall be used, and the trench shall be laid smoothly without violent collision with the groove bottom and groove wall. The pipes are distributed along the trench to reduce the secondary handling. In order to ensure the accuracy of the pipe laying position, it is necessary to place a level ruler with a center scale in the pipe. During the inspection, check whether the center suspension line sagging on the pipeline coordinate center line coincides with the center of the level ruler.
