What is a human defense sealed conduit?

1. The primary focus of the anti-personnel protection sealed conduit is to strictly adhere to the production standards as specified in the 04FS02 atlas. In summary, the core purpose is to address the need for pipeline crossing walls in certain underground projects, especially where there are stringent waterproofing requirements.

2. These structures still require pipeline penetrations multiple times. In addition, pipelines are restricted from expanding or contracting, or moving due to temperature changes, such as from external forces. Moreover, vibration of pipelines under external influencing factors is not necessarily permitted. Overall, the design and manufacturing are considered.

3. The civil defense sealed sleeve, in my view, is sealed on the outside diameter of the pipe or the left side of the sleeve when the pipe passes through, where sealing material is used to prevent water leakage and serve functions like shock absorption.

4. Either a civil defense sealed pipe sleeve or a waterproof sleeve, in my view, is required when removing the concrete structure or shear wall foundation, crossing beams, or when the same-shaped column is being installed. It should be swiftly installed with the civil construction work.

5. After leaving the pre-drilled holes, there was inadequate treatment in the Ivanov casting between the casing and the concrete.

6. Some cases are unprocessable, such as installing rigid waterproof sleeve pipes above the concrete shear walls on basement foundations.

7. "Post-installation of pipeline installation" - Refers to the process of installing pipelines after the concrete floor and common brick walls. Generally, it is almost the same as pre-drilling holes on the concrete floor, and holes can be drilled in the brick walls after this installation.
