[0025] The partition doors of the track area are set up in the tunnel section where the subway runs. Since the subway operation requires the overhead contact network to be energized, the partition doors set up between the section tunnels must have a contact network passing through the door opening. Since the function of the civil air defense door is to resist shock waves, it has airtightness requirements, so special treatment is required at the bus when closing the door. The conventional solution is to cut off the contact network when closing the door or to leave a reserved hole at the position where the bus passes on the upper part of the door body, and then seal it with a component. The existing structural seal is usually set up on the upper part of the door leaf, which generally requires high-altitude work and requires a more complicated installation operation process.
