Waterproof casing is also called wall casing and wall pipe. Flexible waterproof casing is generally applicable to structures where vibrations or tight waterproofing requirements are applied to the pipelines passing through the wall. After the casing is partially processed, primers are applied to the outer walls of the casing (primer includes lutetium or cold base oil). . Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The two are mainly used in different places, flexible waterproof casing is mainly used in the air defense walls, pools and other places where demanding, rigid waterproof casing is generally used in the basement and other pipelines need to wear pipe. In modern water supply and drainage construction, the use of waterproof casing is almost normal. For use and construction problems in the process of use are also plaguing the majority of construction workers, the following by Xiao Bian to explain what is the price of waterproof casing and waterproof casing . Waterproof casing Waterproof casing is also called wall casing and wall pipe. Flexible waterproof casing is generally applicable to structures where vibrations or tight waterproofing requirements are applied to the pipelines passing through the wall. After the casing is partially processed, primers are applied to the outer walls of the casing (primer includes lutetium or cold base oil). . Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The two are mainly used in different places, flexible waterproof casing is mainly used in the air defense walls, pools and other places where demanding, rigid waterproof casing is generally used in the basement and other pipelines need to wear pipe. In the water supply and drainage construction standard, the waterproof casing is divided into a flexible waterproof casing and a rigid waterproof casing. The flexible waterproof casing is mainly used in areas where there are seismic protection requirements, and can withstand the vibration and pipeline expansion and deformation in the pipeline through the wall, or In a building with stringent waterproof requirements, the rigid waterproof casing is mainly used in buildings where pipelines are not subjected to pipe vibration and telescopic deformation. In general, waterproof casing is mainly embedded parts of building walls. , For the convenience of future pipelines to facilitate the flexible waterproof casing is suitable for pipelines through the wall where the vibration or watertight requirements of the structure of the hardware of the pipe fittings, the general production enterprise is based on the Institute of Building Research designed and developed S312 , 02S404 standard atlas manufacturing. 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. Whether it is a flexible waterproof casing or a rigid waterproof casing is a hardware fitting used for pipes through the walls of buildings that are subject to vibration or strict waterproofing requirements, and are commonly used in construction, chemical, steel, tap water, sewage treatment, and other units. The most intuitive difference between a rigid waterproof casing and a flexible waterproof casing is that the appearance is different. The flexible waterproof casing has a rubber water stop ring inside, which prevents water leakage when used in a pool wall. Their installation length is not the same, the standard length of the flexible sleeve is 300mm and the standard length of the rigid sleeve is 200mm, but all of them have in common that they can be arbitrarily lengthened or shortened according to the needs of the construction. Waterproof casing commonly used types 1, ordinary casing - When pipelines pass through foundations, interior walls, floors, etc., avoiding the use of pipelines (pressurized pipelines, such as water supply, heating, etc.), cause disturbances to buildings, and facilitate the installation and maintenance of pipelines. The pipe diameter, material and length are in line with the requirements, installed in the base, interior walls, floors and other pipe through the short tube. ——Ordinary casings are mostly made of welded tubes. Both ends of the casing should be mechanically cut (for example, with toothless saws, etc.), and the wall thickness is not strict. 2, waterproof casing - Specially-made sleeves are provided when pipelines pass through buildings and structures that require waterproofing, such as basements. Commonly used rigid waterproof casing. —— The rigid waterproof casing needs to be welded outside the casing to seal the water ring, and the wall thickness of the casing and the wall thickness of the ring wing are all strictly required, and the weld quality should be ensured. The role of waterproof casing Waterproof casing is a kind of hardware fittings that are mainly used in the pipe through the wall and have strict waterproof requirements. The product is mainly waterproof, anti-settling and anti-leakage. Since the waterproof casing has a good overall performance, this product is mainly used in construction projects. The function of this product is mainly to optimize the waterproof structure of the pipeline site, facilitate the detailed treatment of the waterproof layer construction, and avoid stress on the temperature and other factors. The destruction of the waterproof layer maintains the integrity of the waterproof layer. At the same time, the pipeline was protected, and when the settlement of the building occurred, 1, protect the pipeline from being destroyed (1) Plastic pipes need to be protected through floors. For example, the above-mentioned practice on the u-pvc drainage plastic pipe casing is a protective measure to prevent the pipe roots from being damaged by external forces. (Plastic pipes are most afraid of damage from the roots, because maintenance is very difficult). In the same way, for plastic water supply pipes, installing casing on the floor will not only consider construction or maintenance, but also protect the root from damage. As we all know, the casing of plastic water supply pipes does not have to pass through the floor slabs. However, there is a clear requirement on the height of the floor slabs. The purpose is here. (It can be seen that there are details of the procedure.) (2) When the pipeline crosses the basic wall, see more concrete shear walls, and also install casing to protect the pipeline. When the building is settling, it passes through the gap between the pipeline and casing to compensate for the settlement of the pipeline. The difference between the buildings reduces the pressure on the pipeline. (3) When the pipeline is passed through three joints (expansion joints, settlement joints, and shockproof joints), in order to ensure that the pipeline is not broken or twisted by uneven settlement on both sides of the building's three joints, a casing is usually provided. This type of bushing often has special requirements. Can be customized according to design requirements. (4) When the geothermal coil passes through the expansion joint provided in the middle of the room, it shall be provided with a sleeve on the outside of the coil to protect the heat pipe. 2. It is convenient to install pipelines and maintain pipelines (1) It is not necessary to say much about the casing that goes through the floor; (2) For a casing that has passed through the interior walls of a building, it is not good for maintenance. When pipelines are installed, the operator's space is very versatile and can be used freely. After the user stays in the maintenance, and the replacement of the pipeline (to reach the service age, etc.), the operator's space is limited. Only pipe brackets and sleeves can be used to temporarily secure the pipes for proper operation. At the same time, the setting of the sleeve can also avoid the destruction of the interior decoration when the pipeline is replaced. If the casing is not provided, when the above operation is performed, the wall of the pipeline will be damaged and the wall surface will be damaged. 3, there is a casing of the water room, there is a certain degree of prevention of water seepage, flow, to the role of the lower layer (1) There are two aspects of “preventionâ€. On the one hand, after the completion of the project, the user is in the decoration stage and causes improper flow, which causes tap water to flow and flow down through the casing. On the other hand, after the user enters the station, the cause of the accident causes Tap water flows down through the casing. Moreover, the former is often more than the latter. There are two reasons for the lower layers of the rogue. One is the low height of the bushing; the second is that although the height is enough, the casing is not sealed tightly. Therefore, the specification has strict requirements on the height of the casing: In a room with water (kitchen, bathroom, etc.), the casing height should be 50mm higher than the surviving floor, and the casing of the plastic water supply pipe should be more than 100mm above the surviving ground. And apply grease seal tightly. 4, to prevent cross-contamination (1) When the indoor water supply pipeline must pass under the drainage pipeline when conditions are restricted, the water supply pipeline must be provided with a casing. The length of the casing should not be less than the design requirements to prevent water pollution. (2) For outdoor water supply pipes, due to the restriction of the conditions, the net distance from the septic tank is less than the standard requirement, and the casing must be provided outside the water supply pipe, and the length should be designed according to the design requirements. Waterproof casing price The price of rigid waterproof casing and flexible waterproof casing varies greatly depending on the specifications of different varieties, and it ranges from 20 to 780 yuan. There are two factors that affect the unit price: 1, the size of the pipe diameter; 2, the length of the waterproof casing. The rigid waterproof casing is a steel pipe with a wing ring (an annular ring made of steel plated on the steel pipe) installed in a wall (mostly a concrete wall). It is used for the general pipeline through the wall to facilitate the waterproofing of the wall. The flexible waterproof casing is in addition to the exterior. Wing rings, internal rings and the like, flangene silk, sold in sets, can also be processed on their own, used for pipelines that require shock absorption, such as pipelines connected to water pumps through the wall.
