Usually, it serves as an urban underground traffic artery, and during wartime, it serves as the main place for urban civil air defense evacuation, material storage, or personnel shelter. A station and an adjacent tunnel form a protection unit. At both ends of each protection unit, there is a need to set up interval partition doors that can withstand bidirectional shock wave loads and have a sealing function. They are usually open during peacetime and closed during wartime. The catenary busbar is a transmission line erected above the subway to supply power to electric locomotives. It is suspended and fixed at a specified position and height, and its function is to transmit the electric energy obtained from the traction substation to the electric locomotive. During wartime when the doors are closed, the catenary busbar can be sealed without being disconnected.

Within the range of ±120 height difference, the airtight requirements of the catenary busbar can be met. After the hole size is determined, it can be regarded as a standard and general component, and production can be arranged in advance, effectively shortening the construction period.

[0027] 5. The present invention can seal the subway catenary busbar during wartime and can withstand a certain amount of shock wave, ensuring that the air defense door can be closed in place without disconnecting the catenary busbar. BRIEF DESCRIPTION OF THE DRAWINGS
