Matters to be noted when pre-buried flexible waterproof sleeve sealing of pipes

The temperature will not only affect the progress of construction, but also play an important role in the solidification of concrete. Flexible water casing in the building pipeline through the wall waterproofing blocking , construction site construction process pre-buried flexible waterproof casing will be blocked off, or blocking is not complete, bringing great trouble later, which flexible waterproof casing blocking what matters need to pay attention to, we summarized the following four points, I hope you have help.
 
1 . Cast-in-place floor, column casing through the beam in line with the civil installation is completed, before pouring concrete should be filled tightly with newspaper, straw bales and other soft things to prevent mortar into the casing and junction box caused by blockage.
2 . To prevent outdoor groundwater or rainwater from entering the basement through the waterproof casing, it can ensure a good construction environment for subsequent equipment installation. Therefore, the basement out of the outer wall at the waterproof casing in addition to the use of soft material blocking, in the waterproof casing prefabricated processing, should be used in the casing end of the port welding steel plate blocking, to be waterproof casing pipe installation and then open.
3 . Pipe through the waterproof outer wall, should be pre-buried with the structure of rigid or flexible waterproof casing.
4 . Pipeline through the wall, through the floor, through the roof should be pre-set holes with the structure, to be buried after the construction of the structure and then casing, through the wall pre-set casing at both ends must be sealed with adhesive tape and so on. 02S404 flexible waterproof casing atlas use; after the design institute unified atlas number is to standardize the use of pipeline pre-buried parts requirements, better pipe fittings can be unified to avoid unnecessary loss of raw materials. 02S404 is a flexible waterproof casing production standards and basis, this standard is and other accessories of the pipeline is consistent, such as flange connection as long as the caliber is good, the back of the flexible waterproof casing Water surface flange and pipe connection flange caliber is the same, as long as the pipe through the casing after locking bolts, pipe and flexible waterproof casing is connected together, the construction of late pipe maintenance and repair are very convenient. This is also the big advantage of 02S404 flexible waterproof casing set after the unification.
