Problems solved by technology
[0003] The structure of the protective airtight partition door in the subway section mainly includes a partition wall arranged in the subway corridor. The partition wall is provided with a partition door frame, and the partition door frame is provided with a partition door body, wherein the partition wall is made of bricks. Or it is poured by concrete, and it is easy to construct by bricks, but the structural strength of the wall is poor. By pouring concrete, the structural strength is increased, but it is troublesome to set up the formwork, and the wall takes a long time to form. It is formed by bricks and poured by concrete. , both exist in the poor connection effect of the subway corridor, which cannot be solved well

Description
technical field [0001] The invention relates to subway infrastructure, in particular to a protective airtight partition door for a subway section. Background technique [0002] The partition door of subway area is the main protection facility of subway civil air defense project, and it is an extremely important part of the whole subway civil air defense project, which plays the role of dividing the protection unit. [0003] The structure of the protective airtight partition door in the subway section mainly includes a partition wall arranged in the subway corridor. The partition wall is provided with a partition door frame, and the partition door frame is provided with a partition door body, wherein the partition wall is made of bricks. Or it is poured by concrete, and it is easy to construct by bricks, but the structural strength of the wall is poor. By pouring concrete, the structural strength is increased, but it is troublesome to set up the formwork, and the wall takes a...
