Requirements of flexible waterproof casing

Requirements of flexible waterproof casing
The selection of flexible waterproof casing can meet the high waterproof requirements of the project and also protect the pipeline from building settlement, vibration and so on. As long as the construction is carried out in strict accordance with the construction requirements, the product can be guaranteed to perform its proper function and ensure the quality of the project. Other pipelines (pipelines that do not belong to the above scope): flexible waterproof casing of the pipeline design pressure ≥ the greater of the change in working pressure. Flexible waterproof casing is generally produced by the S312 and 02S404 standard drawing set developed and designed by the Institute of Building Science. Flexible waterproof casing through the wall, non-concrete should be changed to concrete walls, casing must be in the wall at one time maintenance; flexible waterproof casing is widely used in construction, chemical industry, steel, water, sewage treatment and other units. Flexible waterproof casing is mainly used for airproof walls, pools and other demanding places; rigid waterproof casing is usually used in basements and other places where pipes need to pass through walls. Flexible wall waterproof casing is a kind of hardware fittings suitable for structures with strict pipeline vibration or waterproof requirements. General production enterprises in accordance with the building science research institute development and design of S312, 02S404 standard atlas production. Flexible waterproof casing through the wall through the wall, using concrete walls instead of concrete. Rigid waterproof casing through the wall is the outer wing ring of the steel pipe (steel plate ring over the steel pipe), installed on the wall (mostly concrete walls), used for general pipeline through the wall, conducive to wall waterproofing. Flexible waterproof casing through the wall and rigid waterproof casing through the wall are used for pipelines through the building wall, construction, chemical industry, steel, water, sewage treatment and other units with vibration or strict waterproofing requirements. When the pipeline through the concrete structure of the shear wall foundation, beam and shaped column, should be installed with the civil construction. The reason is: after the reserved holes, the secondary pouring between the casing and the concrete is not easy to handle; some cannot be handled, such as the installation of rigid wall casing in the basement foundation concrete shear wall.
