Introduction: Building waterproof engineering is to ensure that the building and its structure will not be eroded by water and the internal space will not be damaged. In the whole process, the flexible waterproof casing has great effect. The flexible waterproof sleeve is 2-4cm thicker than the available pipeline,

Building waterproof engineering is to ensure that the building and its structure will not be eroded by water and the internal space will not be damaged. Here, the whole process is flexible Waterproof casing It's very effective, Flexible waterproof casing It is 2-4cm thicker than the used pipe and is fixed in the wall or plate through which the pipe passes.
Flexible waterproof casing is to use flexible material to stop leakage between casing and pipeline, which has sealing effect. Steel casing is flexible waterproof casing and pipeline with steel raw materials to achieve sealing effect. Flexible waterproof casing is the natural environment for casing application, which is to avoid liquid exposure or leakage (such as reservoir, septic tank, basement, etc.), many more than one ring of waterproof wing rings are lifted on the surface of flexible waterproof casing, so that the casing concrete will become a whole when it is poured into the wall body, and it is not easy to leak water due to cracks caused by expansion and contraction factors. Generally, casing pipe should be used in the case of reservoir, which is the safe passage from pipeline to reservoir. However, the general casing can not be sealed, and then there will be water seepage between the casing and the pipe, and between the casing and the wall. If only casing is used to deal with the water seepage between the casing and the wall, it can not deal with the sealing between the flexible waterproof casing and the pipeline. The flexible waterproof casing can deal with two kinds of problems.
1. Ductile iron pipe, rubber ring socket, d325 × 8 welded pipe and d219 × 6 welded steel pipe are used for main pipe of flexible waterproof casing.
2. Before the construction of the project, it is necessary to carry out bridge detection on the flexible waterproof casing, and its working pressure level shall not be less than 1.5 times of the pipeline pressure. After the raw materials enter the site and before the pipe is buried, the pipe materials and notes shall be tested, including text verification and commodity inspection.
3. Pay attention to the inspection of pipe materials. It is stipulated that the construction enterprise should use the pipe materials manufactured by reliable manufacturers, and check whether the product certificate and structural mechanics test report of the pipe are complete.
4. Pay attention to the inspection of pipe appearance. After the pipes enter the site, the construction material personnel shall carry out inspection on the appearance of the pipes. The pipes shall be free from damage, molting, honeycomb vulgarity and cracks, and the pipes failing to pass the external type inspection shall not be applied.
5. Improve the maintenance of pipe. The flexible pipe manufacturer shall provide the installation of the flexible pipe during the pipe transportation.
