Notes on the installation of flexible waterproof casing
Waterproof casing is mainly used in the construction industry and a variety of different areas of pipe protection range, can bring protection, can make the building more stable, and can facilitate the pipeline for protection and repair, more convenient in the process of subsequent maintenance, so in the construction industry is very widely used, also been promoted. Flexible waterproof casing in the construction industry has also developed a lot of advantages, because it can avoid the impact of the pipeline on the stability of the building, and do not have to worry about the wall or underground pressure on the pipeline, can achieve high pressure strength, the pipeline to play a protective role.
Flexible waterproof casing is suitable for the pipeline through the wall where there is vibration or strict waterproofing requirements of the structure of the hardware fittings, flexible waterproof casing through the wall of the wall, such as in the case of non-concrete should be replaced with concrete walls, and the casing once solidified in the wall; flexible waterproof casing is widely used in construction, chemical industry, steel, water, sewage treatment and other units.
Installation of flexible waterproof casing need to pay attention to what issues; careful installation direction this is very critical, associated with the normal use of casing, because the casing, is in accordance with whether there is a set of water collection pit to determine the direction of installation. Be careful with the use of the occasion casing if the installation in a corrosive place, it is necessary to use sealing materials to do the gap sealing construction. If the casing is used on a non-concrete wall, the wall around the casing should be converted to concrete, and the scope of the conversion should be 20 meters larger than the outer diameter of the casing. Beware of the thickness of the concrete wall where the casing is installed should be more than thirty meters, and if the thickness is not qualified, it can be thickened, such as on one or both sides of the wall, while the scope of thickening should be greater than the outer diameter of the casing by twenty meters. Be careful of the filling material of the casing filling material can be used flexible asphalt hemp wire, can also be used polystyrene material, while the material used for closure, can use polysulfide sealing paste.
