[0002] Civil air defense fortifications refer to underground protective buildings built separately to ensure the shelter of personnel and materials, civil air defense command, and medical rescue in wartime, as well as basements built in combination with ground buildings that can be used for air defense in wartime. Due to the need to combine civil air defense projects with flat stations, a large number of fire-fighting, water supply, drainage and other pipes need to be installed. In order to prevent damage to the water supply and drainage pipes in the later stage, the water supply and drainage pipes need to be protected to improve their impact resistance.

[0003] However, although some protective devices are installed on the surface of the existing water supply and drainage pipes for protection, there are no protective devices to protect the joints of the water supply and drainage pipes. The joints of the water supply and drainage pipes are only spliced ​​and fixed by flanges with fixing components. When encountering external force impact, they are prone to loosening, affecting the sealing of the drainage pipe connections, causing water leakage. Secondly, after being in the dark and humid underground for a long time, the fixing components (bolts and nuts) of the water supply and drainage pipes connected with flanges are prone to rust, which is not convenient for later disassembly.
