Flexible waterproof casing pre-buried installation requirements

The construction method of flexible waterproof casing in the installation process is very important and needs to pay attention to its installation method. Waterproof casing pre-buried in the pipeline can effectively help the pipeline to waterproof, to prevent leakage and other phenomena. For installation conditions are poor or the pipe itself has certain quality problems, need to be repaired. Waterproof casing can be used on top of the wall, and there are very many uses in the construction industry. But for various reasons, we will ignore some details during the construction process, and accidentally be leaking water to the building caused by the loss. If there is no timely patch then these are the waterproof casing role will be affected. Therefore, in the choice of decoration materials to choose a good and reasonable materials. In the installation of construction time we have to follow the formal steps for installation, so that the project can be normal in progress. Waterproof casing pre-buried parts preparation: before the installation of casing to be pre-buried casing, the installation process of waterproof casing to do with gaps and voids and not allowed to appear in the concrete.
Centerline between the casing and the pipe is aligned. Both ends of the casing are welded with casing brackets, and the bottom must also be welded with casing brackets. The casing brackets are usually square steel plates or angles, and in order to ensure that the connections can be firmly fixed, the brackets also need to be set in pre-drilled holes, usually with a diameter of 40 mm. for easy access and fixing, the casing brackets should be set on the casing. The method of setting the casing bracket is the same as the method of anchoring the pipe. It should be designed and then constructed according to the civil construction drawings. Pre-set casing bracket position according to the civil construction design drawing, and then casing bracket pre-determined hole should be processed after all casing brackets are installed in place. Usually leave the casing bracket opening position. Waterproof casing pre-buried parts before use, must be tested. Before the test, carefully check whether the material meets the design requirements, check for leaks, no damage, unevenness and breakage. When testing, the casing through the wall should face upward, and the length of the casing should be the length of the pipe. The pipe through the wall shall be pre-buried after vertical penetration of the wall to ensure that the pipe can be kept in a horizontal state after installation. The end of the pipe should be smooth with the wall, and the casing should not be installed and used vertically or at an angle.
