The invention discloses a catenary sealing device for a subway section partition door and a construction method. The catenary sealing device comprises a sealing plate main body, a moving plate group,an upper pressing plate, a catenary busbar, an elastic rubber block and a sealing strip; the sealing plate main body comprises a bottom beam and a panel; a first notch is formed in the panel; the moving plate group is inserted into a gap of the sealing plate main body, and comprises a moving plate, a connecting frame, a pressing strip and a rolling shaft; a V-shaped second notch is formed in the moving plate, and a first arc-shaped groove is formed in the bottom of the second notch; the pressing strip is connected into the second notch of the moving plate in a pressing mode; a second arc-shaped groove is formed in the bottom of the pressing strip; the upper pressing plate in inserted into the pressing strip, and a third arc-shaped groove is formed in the bottom of the upper pressing plate;a first pore channel is formed by splicing the third arc-shaped groove and the second arc-shaped groove; the elastic rubber block in inserted into the first pore channel; a second pore channel is formed in the elastic rubber block; and the catenary busbar is inserted into the second pore channel. According to the catenary sealing device, the technical problems that a traditional catenary busbar is not tight in sealing, inconvenient in operation and large in space occupation, and cannot be used when the side wall of a tunnel is thin are solved.
Description
technical field [0001] The invention belongs to the field of underground engineering construction, and in particular relates to a catenary sealing device and a construction method for a partition door of a subway section. Background technique [0002] The civil air defense system in the urban subway is an extremely important part of the urban civil air defense. It is used as an urban underground traffic artery in peacetime, and as a main place for urban air defense evacuation, material storage or personnel shelter in wartime. A station and an adjacent tunnel are a protection unit. At both ends of each protection unit, partition doors that can withstand two-way shock wave loads and have airtight functions are required to be opened in normal times and closed in 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. Its function is to transmit the electri...
