Introduction: Sewage treatment rigid waterproof casing is generally used in the basement and other parts where the pipeline should pass through. The pool is to avoid water leakage from the outer wall. It is required that the water pipes passing through the pool should be installed with sewage treatment rigid waterproof casing. After the installation, the rigid waterproof sleeve for sewage treatment is not allowed

Sewage treatment rigidity Waterproof casing It is generally used in the basement and other places where the pipeline should pass through the pipe, and the pool to avoid water leakage from the outer wall. The water pipe passing through the pool should be installed with sewage treatment Rigid waterproof casing After installation, no visible variable is allowed in the rigid waterproof casing of sewage treatment.
The thickness of concrete wall of rigid waterproof casing for sewage treatment shall not be less than 200 mm, otherwise one or both sides of the wall shall be thickened. The diameter of thickened part shall be 200 mm larger than that of flange ring (D4). When the pipeline passes through buildings and structures with waterproof requirements such as basement, the special made casing is set, and the rigid waterproof casing for sewage treatment is common. In the process of installation, it is necessary to weld the sealing ring flange outside the rigid waterproof casing for sewage treatment. There are strict requirements for the thickness of the rigid waterproof casing and the thickness of the ring wing, and the weld quality should be guaranteed.
Pay attention to the method of building the rigid waterproof casing for sewage treatment, and master the application of rigid waterproof casing in sewage treatment according to the method of making pool It is important to master the airtightness when leading to the pool. For example, the design of rigid waterproof casing for general sewage treatment is more prominent, and it is important to fully comply with the requirements, such as how to avoid water seepage and how to prevent water seepage.
The base metal and welding material used in the project must be checked before use to confirm that the material is consistent with the raw material, and the raw material conforms to the design document, and the relevant engineering standard can be used. The design document rules for the project with sewage treatment rigid waterproof casing welding index of 1, the design document related engineering standards or welding operation instructions rule that all welding shall be subject to radiographic inspection or ultrasonic testing The base metal and welding material used in the project should be rechecked.
1. Installation of waterproof casing before pipeline installation: when the pipeline passes through concrete floor and common brick wall, holes will be embedded on the concrete floor generally, and the wall can be drilled through the wall hole later. Before installation, the casing pipe should be installed on the floor. On the wall, draw lines, plant the support frame, find the inclination, and install the casing.
2. Waterproof casing shall be installed together with civil engineering
When the pipeline passes through the shear wall of the concrete structure, the basic, beam and special-shaped column, it should be installed together with the civil engineering. The reason is that the secondary pouring between the casing and the concrete is not easy to handle after the hole is embedded; some cannot be treated, such as installing rigid waterproof casing on the basement foundation concrete shear wall.
